The difference between Torturbo from Twinturbo. What are the differences between Twin Turbo and Buturbo systems? Differences between data systems

Twinturbo and Buturbo what the difference and what differences

You have repeatedly heard the names of Twinturbo (Twinturbo) and Buturbo (Biturbo), but what's the difference? And there is really no difference! Twin-turbo and bi-turbo are all marketing tricks and various names for the same turbocharging system. By the way, read the useful article of the bone of Nezludin about the advantages and minuses of various turbocharge systems

Contrary to the convictions of some "experts" the name of the Buturbo system or Tweinturbo does not display the process of operation of the turbine - parallel or sequential (sequential).

For example, the car Mitsubishi 3000 VR-4 turbocharging system is called Twinturbo (Twinturbo). In the car there is a V6 engine and it has two turbines, each of which uses the energy of exhaust gases from its three cylinders, but they fond of one common intake manifold. For example, German cars have similar on the working principle of the system, but they are not called twinturbo (Twinturbo), and Buturbo (Biturbo).

On the Toyota Supra car with a row six, two turbines are installed, the turbocharging system is called Twinturbo (Twinturbo), but they work in a special sequence, including and turning off using special overflow valves. At the Subaru B4 car, there are also two turbines, but they work successively: a small turbine is blowing on low revs, and at high, when it does not cope, the second larger turbine is connected.

Let us now look at both Bi Turbo (Biturbo) and Twinturbo (Twinturbo), or rather, what they write about them in "these your online":

Bi-Turbo (Biturbo) is a turbocharging system, which is two consistently included turbines. In the Buturbo system, two turbines are used, one small size, and the second larger size. A small turbine is spinning faster, but at high engine speed, the small turbine cannot cope with the air compression and the creation of the desired pressure. Then a large turbine is connected, adding a powerful charge of compressed air. Consequently, the delay (or turbo) is minimized, smooth accelerating dynamics is formed. Buturbo systems are not very cheap pleasure and are usually installed on high-class cars.

Buturbo system (Bitrubo) can be installed on the V6 engine, where each turbine will be installed on its part, but with a common intake. Either in a row motor, where the installation of the turbine is carried out by cylinders (for example, 2 for small and 2 for a hollow turbine), and a large tribone is first installed on the exhaust manifold, and then a small one first.

Twin-Turbo (Twinturbo) - this system is different from Bi-turbo what is aimed at reducing turbo lag or aligning acceleration dynamics, but to increase productivity. Twinturbo systems (Twinturbo) use two identical turbines, respectively, the performance of such a turbocharger system efficiently than the system with one turbine. In addition, if you apply 2 small turbines similar to the performance with one large, you can reduce the undesirable turbolag. But this does not mean that no one uses two large turbines. For example, two large turbines can be used in a serious drag for even greater performance. The Twin Turbo System can work both on V-shaped motors and in the row. The turbine inclusion sequence may vary, as well as on the Buturbo systems.

In general, for even more fun, no one bothers you to stick at once 3 (!) Turbines or more. The goal is persecuted as well as for Twinturbo. I must note that it is often applied to racing drag and never on serial cars.

Do you like turbo or do you have a car with turbocharged? Then join our group!

On modern cars, turbocharging is often used - it allows you to increase the engine power due to an increase in the amount of fuel injected into the cylinder for one cycle. From the middle of the 20th century there are cars in which two turbines are used at once - such a layout is called Twinturbo, Biturbo, Double Turbo and in other words. Often, you can find information about the fundamental differences of Twinturbo and Buturbo - in separate articles, the definitions and essence of unique structural elements are given. Let's try to figure out the layout of these systems and we.

Turbochards are increasingly used to increase engine power

The most interesting moment in this problem is that the fundamental differences just do not exist. Biturbo and its counterpart Twinturbo are simply alternative names of the same superchard systems with two compressors. Moreover, both Biturbo and Twinturbo assume the use of various variations of the technical part.

Different names were invented by marketers of famous automotive manufacturers in order to highlight their products among many similar machines built using the same layout. Interestingly, the Japanese to prefer their twinturbo dual turbochargers, while European companies write Biturbo - it also happened. Machines from both parts of the world come to our country, so the name is Biturbo, that Twinturbo is familiar to the domestic consumer. Therefore, the dispute about the differences between the names of turbochargers can be considered insolvent - and here to learn about the fundamentally different systems used in international practice will be interesting.

If you know what turbocharging is, you will understand that in the installation of two turbocompressors there are difficulties. Both turbines of the BITURBO system have to be installed on one exhaust highway, and a certain distance should be saved between them. The problem is that the far turbocharger will get less energy and work is not so efficient. In the middle of the 20th century, this problem was solved quite simply - the second turbine in the layout Twinturbo had the characteristics of the bearings and the shape of the impeller. Due to this, it was possible to synchronize the work of two aggregates and significantly increase the engine power using the Biturbo system.

BITURBO system is used less and less

However, practice has shown that the Twinturbo sequential layout has several important drawbacks:

• The presence of a serious "turboyama", i.e., the turn range in which the turbines simply do not work;
• Quite a long time of the response to the supply of gas;
• Accelerated wear of the near turbine;
• Disadvantage of installation on V-shaped motors.

The problem was tried to solve various ways. However, the most elegant and efficient engineering decision suggested Toyota, which made the inclusion of the turbocharger of its Biturbo variant. On low speed valves, the valves are closed and exhaust gases pass only through a small first turbine, easily spinning it and ensuring an early exit from the Turboyama. After reaching 3500 rpm, when the gas pressure is already excessive, the electronics opens a special damper, and the hot stream rushes to the second largest turbochargeor, providing a significant increase in engine power.

However, with the mass distribution of V-shaped motors, the biturbo sequential system began to be applied more and less often because it was uncomfortable from a constructive point of view. Approximately at the beginning of the 80s, the twinturbo alternative layout was proposed, in which each turbine was fixed behind several engine cylinders - as a rule, it was about one or another "half of the block. Turbocompressors could be located much closer to the inlet and exhaust collector, which significantly reduced the level of mechanical and aerodynamic losses, as well as increased the engine power. In addition, the Biturbo parallel system using compact turbines allowed to get rid of the "turboyama" and make the motor very sensitive to changing fuel supply.

In most cases, the TWIN TURBO parallel scheme involves the use of a common intake manifold, which simplifies it and makes less costly in service, but limits the dynamic potential of the car. Therefore, as an alternative, Biturbo layout was proposed with separate intake paths and collectors. Among other things, it allowed to adapt the system to use on compact row engines that were previously equipped with exceptionally two turbochargers located sequentially.

However, the most interesting TWINTURBO scheme was offered by BMW - its difference was the location of the turbines in the collapse of V8, and not parties from the cylinder block. Moreover, each of the turbocompressors wasted from cylinders located on both sides of the engine! Despite the huge difficulties that engineers had to overcome, the result exceeded all the expectations. Such an original BITURBO system reduced the length of the "turboyama" by 40% without reducing the reliability of the node. In addition, the stability of the engine was significantly increased and the intensity of its vibrations decreased.

Sometimes TwinScroll turbine is confused with TWINTURBO layout. The latter involves the use of one turbine having two channels and two parts of the impeller with a different shape of the blades. On low revs, a valve is opened leading to a smaller impeller - as a result, the turbocharger accelerates quite quickly and ensures the increase in power without "turboyama". However, with an increase in the speed of rotation of the crankshaft, the pressure of exhaust gases becomes redundant and the second valve opens - only a large impeller is used. As a result, the car receives additional productivity growth.

Of course, such a system has a slightly smaller efficiency than the classic Biturbo. However, in comparison with one turbine, the traction capacity of the engine is still increasing. Of course, the TWINSCROLL layout is complex in production and is considered to be quite unreliable. However, it is currently very often used in powerful vehicles - including in the Biturbo system.

If you know what the mechanical compressor is different from the turbine, then you will understand why these two systems are considered incompatible - the first is driven from the crankshaft, while the turbocharger uses the energy of exhaust gases and combine them almost impossible. However, there is nothing impossible for Volkswagen engineers - in your version of Twinturbo system, they included both nodes. The turbine works constantly, while the compressor helps to eliminate the "turboyam" on low revs. Subsequently, it turns off, but with a sharp press of the gas pedal, it comes into effect, improving the reaction of the engine to supply the fuel.

The result of using such a Biturbo variant has become a significant increase in power, reaching the torque limit on small revolutions, accelerating the revolutions, as well as a decrease in the response time to press the gas pedal. The difference with simple Twinturbo for the driver is practically imperceptible - it only feels easily predicted powerful dynamics and is not distracted by power failures or other problems. However, the system developed by Volkswagen turned out to be very complex in production and unreliable. Therefore, at present, only one of the two boost options uses on brands of brands.

Summarizing the above, we can conclude that the differences in Twinturbo from Biturbo are only in the title. If you are really interested in various boost systems, you should pay attention to parallel and consistent layouts. In addition, it will be less detailed to familiarize themselves with the differences between the turbocharger from the mechanical supervision and the advantages of their joint use.

How do Biturbo and Twin Turbo engines work in cars?

In the literal translation from English, the phrase Twin-Turbo denotes a "double turbo" or "twice turbo". The correct are both translated options. Now let's leave the linguistic aspect and study in detail the technical side of this type of turbocharging.

In order to achieve a noticeable increase in engine power in its design, the turbine is installed. Twin-Turbo is one of the types of car turbo-system and it is on it that we will stop our attention. Twin Turbo implies the installation of two identical turbines at once, which repeatedly increase the performance of the entire turbocharging system. Such a layout is much more efficient to the turbosystem, in which only one turbine is used.

Initially, Burbo was designed to solve the main problem of all inflatable engines - elimination of the so-called "turboyama". This phenomenon is manifested in reducing elasticity and a sharp drop in the engine power on low revs. All this happens at the moment when the engine turbine under the pressure of exhaust gases does not have time to unwind up to optimal revolutions.

Subsequently, it was noted that dual turbines allow to significantly expand the range of revolutions of the rated torque, thereby increasing the maximum power, while at the same time reducing the total fuel consumption.

Did you know? The exclusive Supercar Bugatti Veyron is equipped with four turbines at once, and such a turbocharging system received the corresponding name - Quad-Turbo.

There are several main types of Twin-Turbo systems: parallel, sequential and speed. Each type of turbocharging is characterized by its own geometry, the principle of work and issued by dynamic characteristics.

This is a relatively simple type of turbosystem, the design of which includes a symmetric pair of simultaneously working compressors. Due to such synchronization, a uniform distribution of incoming air is achieved.

Often this scheme is used in diesel V-shaped engines, where each compressor is responsible for supplying air to the intake manifold of its cylinder group.

The decrease in inertia is achieved by reducing the mass of the turbine rotor, since 2 small compressors create greater pressure, spinning at the same time much faster than one large and more productive compressor. As a result, the turboyama is significantly reduced, which was mentioned above, and the engine gives the best characteristics in the entire turn range.

This type implies a layout consisting of two commensurate compressors, which can have different characteristics and work in complementary mode. The easier and fast supercharger works in continuous mode, thereby eliminating the deep and wide turboyam. The second supercharger according to the special electronics signals controls the engine speed and turns on with more severe engine operation modes, thus ensuring the maximum power and fuel efficiency.

On the peak modes of the engine operations are included at once 2 turbines, working in a pair. A similar scheme can be applied on engines with any fuel cycle.

The most complicated and progressive type of turbocharging, providing the widest range of power. Creating a necessary superior becomes possible due to the installation of two multiple compressors interconnected by a special system bypass valves and pipes.

This type of turbocharging is called a step due to the fact that the exhaust gases in the minimum modes are unchecked by a small turbine, and this allows the engine to easily gain momentum and work with greater efficiency. With increasing revolutions, the valve is discovered, which in turn leads to a large turbine. But the pressure it creates must be increased, which makes a small turbine.

After reaching the maximum revolutions, the large turbine issues a huge pressure, which turns a small supercharger into aerodynamic resistance. At this very moment, the automation opens the bypass valve, and the compressed air enters the engine, by passing a small turbine in its path.

But all the complexity of this system is fully compensated for by the flexibility of the engine operation and its highest characteristics.

What are the advantages of using twin-turbo and is there any deficiencies

The undoubted advantage of the Twin Turbo system is high power with a relatively small operating volume of the engine. This also includes a high torque and excellent car dynamics equipped with Twin-Turbo. The engine with two turbines is much more environmentally friendly than the usual, since turbocharging allows fuel to be much more efficient to burn in the system of cylinders.

Of the disadvantages of Buturbo, the complexity of the operation of such a system can be distinguished. The power plant becomes more sensitive to the quality of fuel and engine oil. Turbated engines need special oil, as the service filter service life is noticeably reduced without it. High temperatures in which turbines work negatively affect the entire car engine.

The main drawback of the Twin-Turbo system is a great fuel consumption. To create a fuel-air mixture in the cylinders, a large amount of air is needed, which entails an increase in fuel supply.

Turbines are pretty quickly wear out if you stop the car immediately jumper. To extend the life of Twin-Turbo to give the engine to work for some time at idle, thus cooling the turbine, and only after that you can safely reach the ignition key.

Remember! Twin-Turbo is a complex and very sensitive turbocharging system that needs careful relationships and high-quality components. Compliance with these simple rules allows you to make the most enjoy the speed and dynamics of the car.

Bi-Turbo (Bi-Turbo) and Twin-Turbo (Twin-Turbo), double supervision - differences. So different or not?

Turbated engines are not so simple, as it seems, there are many misunderstandings and uncertainties near this topic. One of these is about the two buildings "Bi-Turbo" and "Twin-Turbo." Not so long ago, he personally witnessed the conversation of two car owners, one assured - that there is a difference, but the other is that there is no difference! So what is the truth? Indeed, what is the difference between these two buildings of turbo engines, let's understand ...

To be honest, then the difference, of course, will be, but it will not be categorical! Just because the names are taken from different manufacturers who set their units with different layout and structure.

However, the Bi-Turbo and Twi-Nuturbo system is essentially the same thing. If you take English and look at the designation, Bi-Turbo and Twin-Turbo, you can see two "BI" and "twin" consoles - if it is rudely translated that it turns out - "two" or "two". Not otherwise - as the designation of the presence of two turbines on the engine, and the same name can be applied to the same engine, that is, they are absolutely interchangeable. These names do not carry some technical differences in themselves, so it is "naked marketing".

Now there may be a question, but why? Everything just has only two questions that they are called to decide:

• Elimination of turboyama, we can say that this is a priority problem.
• Increase power.
• Engine structure.

I will, perhaps, from the simplest item - this is the structure of the engine. Of course, it is easy to install one turbine when you have an inline engine for 4 or 6 cylinders. Silencer then one. But what to do when you say v shaped motor? And three - four cylinders on each strand, then the silencer is two! So put on every turbine, medium or low power.

Elimination of the turboyama - as I wrote from above, this is the task number "1". The fact is that the turbocharged motor, there is a failure - when you click on gas, the exhaust gases need to go through and unwind the impeller of the turbine, it is that time and "seats" power, it can be from 2 to 3 seconds! And if you need to do the overtook maneuver at speed - this is not safe! So you set various turbines, and often compressor + turbine. One works on low revs, that is, at the start to avoid the "turboyama", the second - at speed when you need to leave cravings.

Increased power is the most banal case. That is, to increase the power of the engine, another powerful turbine is installed to a low-power turbine, so they blow two, which significantly improves productivity. By the way on some racing machines, there are three and even four turbines, but it is very difficult and in the series, as a rule, does not go!

Here is the actual and solutions for which the "Twinturbo" or "Buturbo" apply and you know this is really a way out, from getting rid of the turboyama and increasing power.

Now only two main buildings are applied on many cars - the location of two turbines. This is parallel and consistent (known as sequential).

For example, some Mitsubishi have a "Twinturbo", but parallel work, as I have already noted from above, these are two turbines on the V6 unit, one for each side. They blow in a common manifold. But for example, on some Audi, there is also a parallel work on the V6 engine, but the name "Buturbo".

On Toyota cars, in particular, on "Supra", there is a row six, however, there are also two superhairs - they work in a cunning order, they can work at once two, can one work, another no, may be included alternately. It all depends on your travel manner - they seek such work with "cunning" bypass valves. Here is a sequential-parallel job.

As on some Subaru cars, the first (small) air pumps air on low revs, the second (large) is connected only when the revolutions have grown significantly, here is the parallel inclusion.

So there are no difference or there are no differences at all? You know the busy, the manufacturers still distinguish these two buildings, let us know more.

As a rule, these are two consistently included turbines to work. At the bright example, Subaru is one small and then the other big.

Small is spinning much faster, because it does not have a large inertial energy - it is logical, it turns on to work on the bottoms, that is, the first. For low speeds and to low revolutions, this is quite enough. But at high speeds and turns, this "baby" is practically useless, there is a flow, where more compressed air is needed - the second is more severe and powerful turbine. Which gives the desired power and performance. What gives such consistent accommodation in Bi-Turbo? It is almost an exception of turboyama (comfortable acceleration) and high performance at high speeds when the thrust remains even at speeds for 200 km / h.

It should be noted that they can be installed both on the V6 unit (on each side by its turbine) and in the row version (there may be an exhaust manifold here, for example, one with two other cylinders).

The minuses can be called high cost and work on setting up such a system. After all, the thin settings of the bypass valves are used here. Therefore, the installation is due to expensive sports cars, such as Toyota Supra, or on auto elite class - Maceratti, Aston Martin, etc.

Here, mainly the task is not to get rid of the "turboyama", but to maximize the productivity (discharge of compressed air). As a rule, such a system on high revs is working when one supercharger cannot cope with the load increased by it, therefore it is set (parallel) another same. Together they injected air twice as much as we give almost the same increase in productivity!

But what about the "turboyama", what does she get buried here? But there is no, it is also effectively defeated only a little different way. As I said, small turbines are much faster thanked, so imagine - change 1 large, 2 small - performance practically does not fall (work in parallel), but the "pit" leaves because the reaction is faster. Therefore, it turns out, create a normal craving, from the bottom.

Installation can be both in line models of power units and V-shaped.

Production and setup is much cheaper, so this building is used in many manufacturers.

This can also be called "bi-turbo" or "Twin-turbo" - as you wish. In essence, the compressor and the turbo version make one work, only one (mechanical) is much more efficient in the nizakh, another (from spent gases) - in the top! About the differences in pans read here.

As a rule, the compressor is installed on the belt transmission from the crankshaft of the engine, so it is quickly spinning with it as quickly as possible. Thus, allowing you to avoid "pits", but at high speed it is useless - a turbo version is already entering.

This symbiosis is used on some German machines, a large plus compressor that he has a much higher resource than an opponent!

Many are mistaken, considering these turbine systems to differ different!
Twin-Turbo and Torturbo are only different commercial names of the supervision system consisting of 2 turbines.
The name does not displays the turbine work scheme (parallel or sequential (sequential)
For example, Mitsubishi 3000 VR-4 and the name Twinturbo, there are V6 and two turbines, each of which is powered by its 3 cylinders and blows in the common skull. Similarly, Audi S4 2.7, but there is already in the title of Biturbo.Analogically on the Maser of the Gilboa or Quatroport.
On Toyota SupratWinturbo Row six, and turbines there are in a cunning order, including and turning off using special overflow valves (sequential-parallel scheme)
There are two turbines to Nashubaru, but they work sequenters: one-little-turbine is operating on low-speed, the high-speed connector-large.
Bi-Turbo (Biturbo) is a turbocharging system consisting of two consistently included turbines. In the subsystem, 2 turbines are used, one small size is different, this is done because the small turbine is unwinding to significantly, and comes into operation first, then the second, large turbine is spinning, and there is a significantly greater air charge. Thus, it is minimized by the lag, it is formed quite smooth accelerating acceleration of a car without a jerk, characteristic of large turbines, it is also possible to use large turbines on the engine engines in cars intended not only to drive through the racing tracks, but also in city roads, where the possibility of twistor is constantly not always, but It makes sense to get more power with a motor-wide volume, for example, for example with the legislation on the taxes of this country on the litter. Bi-turbo systems are quite expensive, and on this, they are installed, asked in mass production, is made on high-fox cars, such as Maserati or Aston Martin (there compressors).
The such asystem can be installed on the V6 engine, each turbinbabid hanging on its exhaust head, the inlet is general and in an input one, for example, in this case, in this case, the turbine can be included in the velney as pairrally, 2 cylinders per one, 2 to another, So it's a sequence - first a large turbine, then small. There are optional options when the exhaust is suitable for a small turbine only with 2-Cylindrids, and to a large one, respectively, from the 2 remaining, and with a turbine output.

Twin-Turbo (Twinturbo) - in this system of location from the bi-turbo system, the main task is not to reduce the lag, but to achieve greater performance by the pumped airproof airproof pressure. Performance for pumped aircraft, in cases where the motor running on high revs, consumes air more than the turbine is capable of providing, it is possible to drop downward pressure. Two identical turbines are displayed in twinturb systems. Accordingly, the performance of the system is 2 times larger than the system consisting of one turbine, with the applied 2 small turbines that will be equal to one large, then it is possible to achieve a lag reduction, with identical performance. There are existence of the situation when the performance of the existing Bolshesturbin is not enough, for example, when building a MOTDDERGSTER, then a combination of 2 turbines is also used. This such as the Biturbo variant can work both on engines with vaga collapse heads and in row engines. Options for turbines are the same as in Buturbo.
There are also system spaces from 3 and more identical turbines, the result is pursued by Totzy as in Twinturbo. Such systems in civilian use, as a rule, are applied as a rule, to bring powerful sports motors, for cars involved in vygraising.
In modern turbocharged engines (in particular, the V8 diesel), the turbines have a variable impeller geometry. This will increase the turboyama problem and gives high turbocharging potential on the lowest engine crankshaft. In addition, etodduks fuel savings

Twin-turbo and bi-turbo - These are two different production designations of one supercharge system with two turbines. Bi-turbo is such a system that consists of two turbines, which are accepted alternately after each other. They differ in different sizes: one of them is more, and the other is smaller.

A small turbine has a property quickly promotion and activates the first. And then (with more powerful motor vehicles) the second turbine starts to work, which acts on a greater charge of air.

Thus, it creates even overclocking the car without a jerk with minimal delay, which is inherent in large turbines.

It is possible to use large turbines on the engines of such machines, which are created not only for high-speed travel on racing highways, but also for urban trips on ordinary roads.

Bi-turbo systems are very expensive, so they are used exclusively for cars sufficiently high cost.

Also, this system can be used to work the V6 engine, where such turbines will be filled on their head near the exhaust, and for the row motor.

For example, the turbine engine can be included on the exhaust and at the same time, and in successively each other, i.e. the first turns on a large turbine, and after it is small.

There are cases when the exhaust of only two cylinders is applicable to the first turbine, and the second or two remaining. Twin-turbo differs from the bi-turbo system in that it remains important not to reduce delay, but to create a much greater effect of pumping air and more upgraded pressure.

The pumpable air is needed if the engine, acting on high revs, has air flow rates more than the turbine can give.

That is, the pressure of the superior may fall. In the Twin-Turbo system, equivalent turbines are used. Thus, the performance of this system is twice as much as the system with one turbine.

If, for example, to use two small turbines, they will sometimes be equivalent to one large, it is also possible to reproduce and lower the delay.

In some cases, if the effectiveness of large turbines is too small, two turbines can also be applied. Both of these systems can act on engines with in-shaped head collapse and in row motor. These turbines are included in the same in two data systems. There are systems that consist of several equivalent turbines.

Data systems are not at all distributed in mass use, and are mainly used when creating engines for racing cars . This is justified by the fact that racing car It should accelerate as soon as possible, respectively, from the engine and requires increased power initially.

In modern engines with turbines Such turbines have impeller with a changed geometry, which allows you to increase its power at a given load, and increases tURBANDUVA ACTION Even on minor engine speeds, when the flow of gases remains small and unwinding the turbine is not enough for a sharp Lada.

In other words, the efficiency of the engine itself increases, thereby ensuring a very significant reduction in fuel consumption.

Currently, there are such types of engines that have two turbines. However, due to its value, such motors can afford not all car owners. Today, the most popular car engines for which the demand grows every day is Twin-Turbo and Bi-Turbo. Of course, not every car enthusiast knows the difference between them, and at first glance, it can be said that they are identical. However, this is not at all. It is also not necessary to think that BI and TWIN are the same, the same in its properties and qualities of the turbocharging system, but with different names.

TWIN-TURBO turbocharger system

In order to understand this system, it is necessary to clearly imagine its principle of operation. The system produces the necessary air pressure, which should be made in the Move Cylinders themselves. As the arrow runs along the tachometer, the engine loses its power, and the production of the turbine itself is rapidly decreasing. It is in order for the motor to not lose power, and the development of the turbine just increased, and the second one similar to the turbine was built-in.

Of course, the work of such a system should be adjusted independently or in the car service. The turbines can be included in the work at the same time, but it is advisable to configure the turbine so that one of them began their work first, and as the revolutions increase on the tachometer, the second one is increasing. However, with such work, the turbines arises such a problem as turboyama. Also, do not forget that this system can be installed not only on V-shaped engines, but also on ordinary row engines.

BI-TURBO turbocharger system

Bi-Turbo, like TWIN, has two turbines. However, they are distinguished among themselves two completely different in the power of the turbine. If in the first case two turbines have the same power, the Bi-Turbo has one standard turbine and one with an increased power. Turbine data does not need to regulate independently. They are originally configured so that at the beginning of the movement includes the first ordinary turbine, and when the tachometer arrow shows an increasing number of revolutions on the tachometer, the second, more powerful turbine turns into operation. This system provides not only fast, but also smooth acceleration of the machine. In addition, such a supervision avoids the turbists. Such a turbine, as well as twin-turbo, Bi-Turbo can be installed not only on the V-shaped engine, but also on the usual inline motor.

Differences between data systems

First, Bi-Turbo creates a smooth and uniform start and overclocking, and twin-turbo reduces the maximum engine power.

Secondly, BI does not create turboes, which cannot be said about TWIN.

Thirdly, Bi-Turbo allows operating not only around the city and the track, but also on racing tracks, while TWIN-TURBO does not have such an opportunity.
