Chevrolet Cruze. Increased fuel consumption. Chevrolet Troit Cruz: reasons and methods of elimination badly pulls Chevrolet Cruise 1.6

the main / Engine

The arms of jerking car Chevrolet Cruz worsen security and driving comfort. The appearance of jerks can speak, both about a serious malfunction and about the easy stop breakdown.

Tightening with the identification of the problem is not worth it, as this can lead to excessive wear of the main nodes of the car.

Ignition system

The most common cause of the jurles of the Chevrolet car Cruz are ignition pass due to faulty candles. To eliminate breakage, you need to change them to new ones.


If the replacement of the candle set does not help, the fault may be hidden in the ignition module. To diagnose a malfunction, you need to check the coils and high-voltage wires. In case of detection of a defective element, it is replaced.

Upon reaching a car 120 thousand km, car owners are confronted with problems in the throttle node. The car ceases to obtain a fuel-air mixture of normal composition. To eliminate the fault, it is necessary to remove the throttle node and clean the damper.

Injectors

The absence of a normal spraying torch is the cause of the unstable operation of the power plant. As a result, the car is twitching both when starting and overclocking.

To eliminate a malfunction, it is necessary to rinse the nozzles from the deposits, which were formed due to the presence of a resin in gasoline.

If the cleaning did not help and the torch spray did not become normal, then the replacement of a faulty nozzle is necessary.

Filters

The negligence attitude towards carrying out maintenance can also be the cause of why the thrust has disappeared and the car began to twitch. The oil filter is most often clogged. The absence of normal lubrication circulation in the circuit leads to excessive efforts in friction nodes.

The surfaces appear on the surfaces, the engine ceases to work steadily and Chevrolet Cruze begins to twitch. To troubleshoot a malfunction, you need to replace the filter and oil. If there is excessive wear, complete disassembly of the power plant and the defecting of the main elements appeared.

The cause of the velinge of the car at speed and when overclocking can be a scored fuel filter. The lack of normal pressure in the fuel line leads to an unstable supply of fuel to nozzles. Therefore, the engine operates normally on small revolutions, but when the load appears, it starts to collect. To troubleshoot a malfunction, you must remove the fuel filter and clean it.

The reason why the car twisted can be hidden in a clogged air filter. This malfunction usually occurs gradually. The engine ceases to obtain the normal composition of the fuel-air mixture. As a result, its power drops and the car twisted during acceleration. To eliminate the fault, you need to remove the old filter element and replace it with a new one.

Unsuccessful upgrade by car owner

The most common reason why after modernization the car twitches, is chip tuning.

Incorrect reconfiguration of the motor control unit leads to the fact that the car installation of the car ceases to work stably. This in turn causes twitching Chevrolet Cruz.

To eliminate the fault, it is required to return everything to the factory settings or contact the tuning studio for the normal reconfiguration of the motor ECU.

In the most difficult cases, jerking is caused by the replacement of the standard elements of the power plant on the stock. The owners of Chevrolet Cruz with a 1.6 liter engine are most often resorted to this type of tuning. In this case, it is necessary to replace non-corporate elements on the branded.

Clutch

Sporty ride style leads to excessive clutch wear. The problem is especially relevant for cars with a 1.8 liter power unit. As a result, vibration and jerking when touching from the place, as well as at speeds. The amplitude and intensity of the jerks may vary depending on the revolutions. To eliminate the fault, the clutch basket is usually changing.

Transmission

In cars with a manual transmission rarely, the reason for the jerking of the machine occurs due to the MCPP. This situation is possible only due to the fact that the box is overly worn. Most often, the jerks occur on the first gear.

The machine is less reliable compared to mechanics. Damage in friction packages and a hydrotransformer leads to the occurrence of vibrations and jerks during overclocking.

To eliminate the malfunction, you need diagnostics of the gearbox and replacing the elements failed. Very often car owners resort to the purchase of contract automatic transmission.

The operation of the automatic transmission change box directly depends on the oil. In the system, it performs not only a lubricating role, but also transmits an effort. Therefore, its late replacement causes the absence of normal operation of the machine and the car begins to twitch. In most cases, it is impossible to solve a simple replacement problem with a disassembly of the automatic transmission and flushing system.

When interruptions, the engine is unstable running at idle, does not develop sufficient power, gasoline extensive. In addition, it is possible to fail the neutralizer of exhaust gases. Interruptions, as a rule, are explained by the malfunction of nozzles or electrical displacement (see ""), a malfunction of the spark plug of one of the cylinders, air seats into one of the cylinders. It is necessary to find a malfunction and if possible to eliminate it.

1. Lay the engine and leave it to work at idle. Come to the exhaust pipe and listen to the sound of the exhaust. You can bring your hand to the cutting pipe of the exhaust pipe - so interruptions are better felt. The sound should be smooth, "soft", one tone. Cotton from the exhaust pipe at regular intervals indicate that one cylinder does not work because of the failure of the candle, the absence of a spark on it, on the failure of the nozzle, about the strong air secession into one cylinder or a significant decrease in compression in it. Cotton through irregular intervals arise due to contamination of nozzle sprayers, strong wear or contamination of spark plugs. If cotton occur after unequal intervals, you can try to independently replace the entire set of candles regardless of the mileage and appearance, but it is better to do after contacting the car service to diagnose and repair the engine control system.

2. If cotton is regular, stop the engine and open the hood. Check the state of the ignition system wires. The insulation of high-voltage wires should not be damaged, and the lugs of the wires should not be oxidized. If there are damage to the wires, replace the faulty wire.

Useful Tip: The most simple and at the same time an effective way to check high-voltage wires is the dark check. Install the car in a dark place, let the engine and open the hood. Inspect the high-voltage wires. If the insulation of the wires is broken, you will see the characteristic sparkling of the blue-violet color ("Northern Light"). In this case, high-voltage wires require a mandatory replacement.

3. Remove the spark plugs (see "").

Warning: When removing the tips of high-voltage wires, never pull the wire itself. Hold your hand directly for the tip, before removing, check it out of the side to the side and then pull.

4. Inspect the candles and compare their appearance with the photos shown in the next subsection "". If the candle is black and wet, it can be thrown out.

5. If all the candles look good, install them in place and connect high-voltage wires. The operating order of cylinders 1-3-4-2, the numbering of cylinders (1, 2, 3, 4th) is carried out from the pulley of the engine crankshaft.

6. Take a spare candle. In any way, lock it on the engine.

Connect the high-voltage wire of the 1st cylinder to the spare candle. Let the engine. If the engine interruptions did not intensify, replace the candle in the 1st cylinder is obviously good, put on the high-voltage wire and let the engine. If interruptions intensified, repeat this procedure consistently with all the cylinders to reveal the faulty candle.

WARNINGS: Reliable contact of the body of the candle with "mass" is required, since when an additional spark gap appears, greater than the gap between the candle electrodes, it is possible to damage the high-voltage chain of the ignition coil or the engine control system.

Trying to be described above, try to spend for the maximum short period of time, since with a long admission to the catalytic neutralizer of exhaust gases of unburned gasoline, it may fail due to overheating, since gasoline will burn in it.

If, as a result of the measures taken, the engine interruptions are not eliminated, check the compression in each of the cylinders (see ""). Normal compression is more than 1.0 MPa (10 kgf / cm 2), the difference in more than 0.1 MPa (1 kgf / cm 2) in one cylinder indicates the need to repair the engine.

Many owners of Chevrolet Cruz faced the fact that the engine began to trim. The reasons for the effect may be quite a lot. How to troubleshoot try to figure out.

Engine diagnostics

Why Troit engine Chevrolet Cruz? Before proceeding with the analysis of the mechanical part of the malfunction, many owners and mechanics are recommended to diagnose the car. Maybe it's really not worth climbing the mechanical part and look for a fault there, but it's just worth seeing that in this case the electronic engine control unit will show.

Chevrolet engine Cruz.

To diagnose the engine, you will need a cable for connecting to a car (OBD II), a portable PC or tablet, as well as the appropriate software.

Connecting and synchronizing with the car, diagnoses the state of the electronic control unit, as well as analyze the errors that it issued. Based on this information, you can understand whether all the sensors are working, and whether there are problems in software.

Icon "Check" and Troy - What is the reason?

The next step will be the inspection of the engine sensors using the tester. They are diagnosed by calling contacts for performance in the onboard network and at the return of the impulse, which goes to the ECU. So, what sensors need to be checked:

  • Coolant temperature sensor.
  • Mass flow sensor.
  • Idle regulator.
  • Knock sensor.
  • Crankshaft position sensor.

When exiting the meter, it must be replaced. After that, you need to reset all the errors that were detected in the control unit. The electronic procedure is completed.

Computer diagnostics as a malfunction for troubleshooting.

Faults in systems

If the electoral cannot be detected in the electronic part, then you need to go to the analysis of the mechanical part. So, on the occurrence of the effect of the trimming is affected by one of three systems - air, fuel and spark. Therefore, it is worth checking each system separately.

Spark

In this case, it is worth considering the output of the spark plugs and high-voltage wires. Checking these items is quite simple. To begin with, it is worth removing from the car wires. To do this, pull the tip of the wire with the candle, and the second from the ignition coil. Then, with the help of a candle wrench, spark plugs from the block head are unscrewed.

Troit is a matter of candles.

The diagnosis of candles is simply carried out. To begin with, it is necessary to view the elements visually for cracks or damage. Clear the contact group by cloth if they are contaminated and set the candle back. The high-voltage wire is checked with the tester for resistance. Previously, each product should be examined for a breakdown of isolation.

Or maybe this candles are to blame?

Fuel elements

In the high-quality combustion supply process, three details play a role: pump, filter and nozzles. First, examine the immediate elements of injection into the cylinders. For this, they are removed from the vehicle and are installed in a special stand, which will show - how suitable it is suitable for further use. After that, it is worth carrying out the cleaning procedure.

Fuel filter - the reason for all troubles.

The next is worth checking the fuel pump. It is located in the fuel tank, and you can only get to it from the cabin, after removing the rear sofa. After that, the power and fuel lines are turned off. Then, it is necessary to remove the fuel pump outside and inspect the filter grid. If it is dirty and clogged, it should be replaced.

In the case of a filtering element of fuel, then everything is simple to change. This item is unbalanced and accurately determine the state will not succeed.

Air flow

Another system, without which the ignition of the air-fuel mixture is impossible. To begin with, it is necessary to dismantle the element of the filtering air (air filter) and inspect its condition. If it is too contaminated, it should be replaced.

DIY repair of the car.

In addition to the air filter, it is worth viewing the state of the throttle. A too contaminated element can be twisted and not to give the air normally to the combustion chamber. So, to clean it, it is worth it first to dismantle and then clean the liquid to clean the carburetors.

Also, to be mixed with choke, it is recommended to clean the air corrugation that supplies air to the damper and the mass flow sensor. The DMRV is equipped with a mesh-indicator that passes air, and adjusts the amount that is required for incineration. The clogging of the element can lead to incorrect indicators. The damper, in turn, will not be closed in the desired position, which will lead to excess air in the combustion chamber.

Output

The reasons why Troit engine on Chevrolet Cruz can be determined independently, but not all motorists can be eliminated themselves alone. Therefore, if the induced materials in the article did not help, or found themselves, too complicated for understanding, it is recommended to contact the car service.

Causes of big fuel consumption

There are several typical errors that allow inexperienced drivers leading to fuel consumption. Remember that the extra volume of gasoline or diesel fuel will be spent at:

Air conditioning or climate control system. The functioning of these devices is associated with the operation of the compressor. After all, the pump is needed to rotate the pump pullee, which is taken from the spinless crankshaft. And it requires an additional fuel.
The operation of the heating system. This applies not only to the work of "stoves", but also heating seats, glasses and mirrors (in machines where these options are provided). Logic here is similar to the situation described above.
Sharp overclocks. If you like to dramatically touch the traffic lights or elsewhere, then be prepared for your car to spend more fuel than usual. This is due to the fact that any transition process (in this case, bringing the car in motion) is associated with increased energy consumption. And than he is sharper, the more energy you need. Therefore, try to trim smoothly. So you will not only save fuel, but also save the tires, grip and nodes of the power unit.
Engine operation at high revs. Try not to fatherize. This will not only save fuel for your car, but also will be favorable at the engine work as a whole.
Use of low-quality fuel. Try to refuel on the proven gas stations, and pour the fuel brand to the tank, which is recommended by the automaker. You will burn bad fuel worse, gives an insufficient amount of energy and requires additional costs.

Technical reasons for increasing fuel consumption

First, let's understand with technical problems that contribute to the increase in the consumption of gasoline in the car. We find out the most common causes associated with the engine and other elements due to which the flow rate increases.

Engine wear

It usually occurs due to the large mileage of the car or when its incorrect operation. Some moments related to engine operation:

The temperature of the coolant (coolant) is lower than calculated;
- with a cylindrophone group;
- with a crank-connecting mechanism;
-Inutrition mechanism of gas distribution and non-regulated valve gaps.

Clutch wear

When the driver needs to keep high speeds in order to travel from place and switches to increased gear - this directly affects fuel consumption. It will help in this case the clutch replacement.

One of the reasons for the increased fuel consumption is the wear of the clutch disk. The situation is quite simple here. In the process of touching the motor consumes more fuel than with constant revs. This fact is present even with a good clutch. If the disk or other parts of the system are faulty, it turns out that the fuel is consumed, and the car stands still. The more often the car rises from the spot, the greater the overrun of the fuel takes place.

In critical cases, such a situation may occur even when driving in constant mode. That is, when the clutch disc does not provide synchronous rotation of the engine and gearbox. This situation, though rare, can happen in the most "running" cases.

Diagnose clutch wear is simple enough. To do this, put the car on the handbrake, turn on the fifth or fourth gear (depending on the gearbox, that is, the highest) and try to touch. If at the same time you do not stuck with gas - this means that the grip must be repaired or change completely.

The ignition is incorrectly configured

Incorrect ignition is also the cause of increased fuel consumption. In particular, if the engine "Troit", then gasoline from the non-working cylinder is ejected directly to the exhaust system. This leads not only to the overruns of fuel, but also to increased wear of the catalyst.

If the ignition is simply appointed incorrectly, the situation occurs when the fuel is not completely combustible. That is, the spark occurs before the fuel mixture appears in the cylinder in full, or after. In any case, this leads to its incomplete combustion. And this automatically means that the fuel is being consumed.

Therefore, always follow the state of the ignition system. The amount of consumable fuel directly depends on this. In addition, an incorrectly configured ignition system can cause problems when starting the engine.

Wear tires

If the tires are rather worn or the pressure in them is less than the norm, it will also lead to the fact that the car will begin to "eat" more than "eating". In such a situation, it is necessary to replace the tires, and regularly check tire pressure.
Low profile tires with a wide protector create increased resistance, and accordingly, increased fuel consumption.

Brake system malfunctions
They are different, consider those that lead to an incomplete solution of calipers when the so-called "subcinition" occurs. If the caliper is not completely cleaned, then with time not only brake pads become unsuitable, but also discs. Due to excessive friction and resistance force, fuel consumption naturally increases.

Introduction Candles

Through unsuitable candles, the car works incorrectly, as a result - an additional load on the engine. This leads not only to the fact that there is a great fuel consumption, but also to a general deterioration of work. To avoid, you need to check the candles.
Such an inspection includes an inspection of the color of the nagar, the electrode clearance measurement, check the resistor on the breakdown. Also, it is worth paying attention to the place of the adjoining of a white insulator to the threaded part of the candle - the red flask is unacceptable.

Scored nozzles or carburetor

The slaughtered nozzles are one of the most common causes of fuel recalculation. They are clogged as a result of natural reasons. Such is the use of poor-quality gasoline, a late replacement of the fuel filter, the ingress of dirt into the windscreen space and so on.

With the nozzles clogged, a violation of the form of sputtering of fuel in the combustion chamber occurs. Because of this, the formation of the fuel mixture is disturbed. That is, for this process, a larger amount of gasoline is used than necessary under normal conditions.

In some cases, due to clogging, the engine can start troitting. This is expressed in reducing the dynamic characteristics of the car. It is also possible to learn the engine at elevated circulation, even in idle mode. It leads to an increase in fuel consumption.

Similar arguments are valid for cars with a carburetor engine. When clogged, the carburetor arises the same situation with gasoline overrun and falling dynamic characteristics.

Therefore, always follow the state of the fuel system, in particular, the injectors on the injection engine and the carburetor on the carburetor. Their clogging is the direct cause of fuel recalculation.

Low-foam fuel is also well affected by the flow rate (for low price and poor quality accounted for quantities).

Lambda Probe or DMRV breakdown

Significant fuel consumption can also be caused by the failure of the oxygen sensor (lambda probe). Its task is to control the amount of oxygen, which is part of the fuel mixture. Therefore, if this sensor is faulty, the mixture will be created incorrectly, and this will result in fuel consumption.

Lambda probe is quite fragile. There are a number of reasons for which it may fail. Among them:

Depressurization of its housing and penetration into its exhaust gases;
-The surveillance of the sensor (this may be caused by the incorrect operation of the ignition system);
-theless aging and wear;
-The closers with the car power grid;
-Maehanic damage to the sensor.
Similar arguments are valid and relative to the air flow sensor (DMRV). It is intended to regulate the air supply level into the engine cylinders. Sensor malfunctions to identify easy. As a rule, while the engine begins to work unstable, especially at idle (very high or low "jumping" turns), the loss of dynamic characteristics (the car is poorly accelerated). The mass flow sensor is not subject to repair. It can only be replaced, although its cleaning can temporarily correct the situation.

Crashing air filter

Recommended replacement frequency - every 15,000 km of mileage. Requires a timely replacement of the air filter, because if he is scored and you ignored it, then be prepared for the fact that the car appears a good appetite.

The consumption also affects the use of air filtering elements with heavy or-made predominates, since, as in the case of a scored filter, the air resistance increases. Filter elements of light type are recommended to resist the air flow to be minimal.
