Daewoo Nexia Ignition Candle Replacement. Candle gaps on Daewoo Nexia which candles on Daewoo Nexia

the main / Tuning

Selection of candles on the 8-valve engine Daewoo Nexia can be carried out exclusively according to the manufacturer's instructions. Nevertheless, a thoughtless purchase at first glance similar candles in the nearest store can turn out not only the waste of nerves when you refuse to start with minimal frost, but it can negatively affect both fuel consumption and on the dynamics of the car. Let's discern in this issue more.

Ignition Candle Parameters The manufacturer chooses, based on the parameters of the combustion chamber - pressure, type of gasoline and operating temperature.

In specific conditions, the combustion chamber of the 8-valve motor SESS is very important to choose the desired gallinal number of the candle. This is the conditional parameter characterizing the pressure at which the self-ignition of the mixture occurs, without a spark. Western companies slowly depart from this parameter, conventionally divided candles on hot and cold. Cold candles are screwed into forced sports engines, and hot goes to all other gasoline engines operating without extreme loads.

Marking

Daewoo unconditionally recommends use in the 8-valve motor SonS candle NGK R BPR6E. (Catalogue number 94837756 ). How decent alternative stands Candle Champion RN9YC. . To understand what what, consider closing the marking of these candles. And at the same time and select decent replacements, according to the declared parameters. On labeling NGK:

  • BP - diameter of the threaded part 14 mm, turnkey size - 21 mm;
  • R. - The resistance to suppressing radio interim is mounted in the candle;
  • 6 - a calil number;
  • E. - The length of the threaded part is 19 mm.

The gap between the electrodes in this candle is not specified (it is indicated by the latter), therefore, it must be standard - 0.7-0.8 mm.

Champion RN9YC.

Original Champion RN9YC candle for 8-valve DEU Nexia.

According to standard Champion RN9YC. Marking means the following:

  • R. - mounted resistance;
  • N. - Thread diameter 14 mm, turnkey 21 mm;
  • 9 - a calil number;
  • Y. - The heat sink cone stands for the housing;
  • FROM - Candle covering material - copper.

Nickel and iridium candles, is it worth it?

In addition to the standard, on sale there are candles with nickel or iridium spraying or with electrodes from iridium alloys, there are more expensive of gold and silver alloys.

In principle, such candles should be an order of magnitude longer than standard. If the classic candle requires a replacement after 50-60 thousand, then Iridium can be left 100, and 120 thousand km. Summing up, let's say that the candle can be at least from platinum, but her calm number is obliged to be within the manufacturer allowed by the manufacturer (6-9). Light all launches and stable spark!

In the electronic ignition system, which is one of the most important components of a modern car, high voltage current is created and distributed through electronic devices. The electronic system has many explicit advantages, and also makes it easier to launch the engine in winter.

troch depending on the car model. The electronic control unit processes signals from the input sensors, affecting, in turn, on the igniter. The igniter, the basis of which is the transistor, is a kind of electronic board, which includes / turning off the ignition. When the transistor is open, the current goes on the primary winding of the coil. If the transistor is closed, its cut-off is carried out, and the current is guided by the secondary winding of the coil. The electronic ignition system may have different coils: one common, individual or dual. Common coils are used in systems that have a distributor. Individual coils are installed directly on the candle, so high-voltage wires are not used in such a system. Dual coils are used in direct ignition systems. If the engine has four cylinders, on the 1st and 4th, and also on the 2nd and 3rd cylinders are installed on one coil, each of which is responsible for

Ignition systems: from simple to the best!

The ignition system is an integral attribute of any gasoline or gas engine. With all the manifold of technical nuances in this issue, all ignition systems with the dynamic distribution of the supply voltage can be divided into contact and non-contact. The following article is devoted to their main features, as well as reasons for the occurrence of systems with a static voltage distribution (electron ignition).

switch. Initially, such blocks possessed extremely low reliability (sometimes even less than 10 thousand km.) However, in the process of design improvements, this parameter was derived to a more or less acceptable level. Contactless ignition systems made it possible to reduce fuel consumption, simplify the launch of the car during the cold season, increase the engine torque on small revolutions and its power at high, and also slightly reduce the harmfulness of exhaust gases due to the increase in the power of the spark and the more complete combustion of the fuel mixture. Nevertheless, the control of the ignition advance angle was carried out using physical sensors included in the track. The interrupter-distributor ("TRABLLER") The ignition distributor, also known from the motorists called "Draver", is an integral part of both contact and contactless ignition systems, even in the second case, its design is somewhat different

For the internal combustion engine, the ignition candle is an important element without which the power unit will not work. Over time, the efficiency of the ignition elements is worsening. As a result, urgent replacement is required.

When is the replacement of candles in Daewoo Nexia?

The Russian automaster advise to replace the candles on Daewoo Nexia once every 15,000 mileage kilometers. It is explained by the low quality fuel and a harsh Russian climate. Note: Ignition element withstands high loads. A high-quality ignition element cannot be cheap. If the ignition element faults are malfunctioning on the instrument panel, Check Engine light can light up.

Replacement is recommended to be carried out in a timely manner. This will reduce the cost of purchasing additional faulty equipment and fuel (gasoline consumption with faulty ignition elements increases significantly).

Visual Ignition Candle Diagnostics:

  1. The presence of mechanical damage in the form of a nagar, breakdowns, etc.
  2. Check the gaps between the electrodes. The distance must be within the factory values. For four-cylinder engines, the gap should be approximately 0.7-0.9 mm.
  3. The presence of molten electrodes. Arises due to overheating of the power unit, setting the wrong ignition moment, etc.;
  4. The formation of an oily plaque on the surface of the candle element and electrodes. It may have been damaged rings or oil-challenged caps.

Differences of the types of spark plugs

Candles are distinguished by:

  • The number of electrodes;
  • Material that was used in the manufacture;
  • A calic number.

Budget standard candle Most common. It can boast a small resource. The electrode is made of heat-resistant metal. Over time, traces of wear appear. Low cost allows them to change periodically without thinking about quality.

Multielectrode candles. Have a few side electrodes. The resource of such parts is significantly increased.

Pluses of multielectrodes:

  • Spark appears at the right moment;
  • Fuel burns without a residue;
  • You can use a depleted mixture;
  • Minimization of the exit of harmful waste into the atmosphere.

Platinum and iridium candles. Appeared not so long ago.

Properties:

  • The central electrode has a thickness of up to 0.7 mm;
  • The side electrode is pointed, has a special profile.

Benefits of platinum and iridium candles:

  • Long service life;
  • The effect of self-cleaning.

How to independently change the spark plugs in the Dae Nexty?

Before starting the procedure for replacing candles on Daewo Nexia 16 valves, it is necessary to prepare. It will be necessary to study safety and pick up the necessary toolkit that will be needed.

Safety regulations:

  1. Car must be de-energized. Disable the minus terminal of the battery.
  2. You need to work in gloves. This will exclude the likelihood of burns and secure from small injuries: random scratches and small blows.
  3. The procedure is carried out only after the engine cools. After the trip you need to wait until one hour while the engine temperature decreases to permissible values. note: Spark plugs are very hot. Be careful.

Required tools and materials:

  1. Candle wrench;
  2. Screwdriver;
  3. New ignition elements;
  4. Pure rag;
  5. Brush for cleaning the contamination from the surface of the candle element.

Step-by-step candle replacement instructions:

  1. Open hood.
  2. Disassemble candle tips. It is impossible to pull the wires and pull. They can break.
  3. Remove the ignition elements. Locate next to the cylinders. By quarrels on the candle, you can reveal a problem cylinder. Please note: when unscrewed, problems may occur. As a result, the thread may be damaged. You will have to start the power unit, warm it up and try to unscrew the ignition elements re-.
  4. By installing new details, you need to remember that cold parts cannot be twisted into a hot engine. In the future, unscrew it will be impossible.
  5. Tightening torque is 20 nm. It is possible to determine the force using a dynamometric key.
  6. Collect everything in reverse order.

The procedure for replacing ignition candles in Daewo Nexia 16 CL completed.

Very often, the problems with the engine of the car arise due to the fact that a gap is incorrect in the spark plugs between the electrodes. Such a situation is often provoked by the fact that manufacturers of these parts in most cases say that there is no need to adjust the clearance in the ignition candlelight. But this approval is made incorrect and unreasonable, because each car owner will not be superfluous to know how to check and adjust the clearance in the ignition candlelight.

Clear

It is clear that if, for example, there is no spark on the ignition coil, then the clearance in the candlelight is completely nothing to do with it. But still, this value has an important impact on the operation of the engine. In order to understand it better, it is necessary to consider the processes that occur in the combustion chamber when the air-fuel mixture is flammed from the spark. At this point, the cylinder filling is compressed with the piston. The hydrocarbon air mixture at the same time is condensed to the limit and that the spark has passed successfully through such a dense substance, the difference in potentials is needed.

Why is the adjustment of the gap in the ignition candle

In standard gasoline engines, the ignition system is designed so that it can work normally only if all elements of the mechanism are working. In particular, you will not hurt to know how to check the coil, how to diagnose the generator, because each of these nodes affects the efficiency of the engine.

And even a small violation in all this complex mechanism, for example, a nagar on the candlelight may cause not only the deterioration of the engine, but also its breakdowns. As for the gap in the ignition candles, then for example, if its natural increase occurred, the spark may simply disgrace the power to break through the dense mixture of air and hydrocarbon. Naturally, it will have to spend more energy to break through the breakdown and as a result, the sparks are fused, which in turn, in most cases, reduces the engine power.

When studying the process of work of automotive spark plugs, it is often necessary to encounter some more not fully studied factors. That is why if the question arises, "what candles should be on your car", the answer must be unequivocal - the original, which the manufacturer recommends. It is also important and periodic verification of candles, which implies the determination of the size of the gap and its adjustment if necessary. As a rule, each manufacturer of the engine provides recommendations for the required gap and it is better to observe them, only so you can guarantee high-quality operation and complete operation of the engine.

Drivers with experience, which already have a clear idea of \u200b\u200bthe spark plug device, changing the clearance in the candles, can affect the power and operation of the engine. But it should be remembered that the wrong gap can and negatively affect the engine power and on fuel consumption, as well as mediocre the cause of the increased load on the crankshaft and the piston system.

It should also be noted that in old models of engines, the candle clearance is not as important as in modern. In the work of the latest modifications, the maximum compressed mixtures are used, and therefore the requirements for the accuracy of the gaps are very high. For example, if you disrupt the value of the candle clearance on a four-stroke-dual-litter four-cylinder eight-ganglip engine only by 1/5 millimeter, this will increase fuel consumption by 4% and will lead to the loss of the power engine for about the same.

Check and adjust the ignition candle clearance in the service center and independently. It is best to follow the recommendations of the manufacturer or the advice of experienced motorists to correctly place the gap. Do not forget that at least through every 15 thousand kilometers this procedure must be repeated. Only so your car will always be fine and please the maximum speed and power.

Elephant Ignition Candle Clearance

The interelectrine spark plug clearance is of great importance, since it is too large and with too small a gap, the size of the spark is changed, which leads to a decrease in the efficiency of the engine. The gap must always meet the specifications.

When combining the fuel-air mixture, the electrodes of the candle are slightly overtaken. It also contributes to a spark discharge that knocks out metal particles from the electrodes, as a result of which the interelectrode gap increases with an increase in the duration of the operation of the spark plugs.

For breakdown of a too large interelectrode gap requires a higher voltage, which can lead to ignition pass, or the engine cannot be allowed at all. Therefore, it is necessary to check and adjust the gap if necessary.

The clearance is checked with a wire pattern or probe, and adjust the lateral electrode. The clearance must be within 1.0-1.1 mm.

Diagnostics of the status of the engine in the appearance of the spark plugs

According to the appearance of the spark plugs, approximately can be judged on the state of the engine, deviations in its operation from optimal parameters. The check must be carried out after a thorough warm-up of the car engine at the speed automotive highway. Checking after a trip to a short distance can lead to erroneous results. During the inspection, carefully inspect the top of the thermal cone of the insulator with the central electrode and the side electrode.

Light gray or brown color of the insulator cone

it indicates that fuel injection and ignition systems work normally, ensuring the cost-effective operation of the engine.

Large sediments point to the use of fuel brands or engine oil that do not meet the requirements of the manufacturer. If possible, replace the brand of motor fuel and, accordingly, oils.

Large sediments appear in the case when the engine is often used to travel for short distances and does not heat up to normal operating temperature, the combustion temperature of the fuel does not correspond to the one at which the carbon oxide content increases.

The white color of the insulator cone indicates that the engine works with too much the ignition advance angle (early ignition), which is characteristic of the ignition advance control and operation of the detonation sensor.

The melting of the central and lateral electrodes shows that the calle number of the spark plug does not match the desired, the functioning of the adjustment angle of the ignition and the detonation sensor is impaired or the cooling system operating mode is broken.

The destruction of the upper part of the insulator cone - indicates that the fuel-air mixture burns with detonation due to the control of the ignition advance angle, the functioning of the detonation sensor, the mode of operation of the cooling system or depletion of the fuel and air mixture due to the possible air supply.

A yellow colors on the top of the insulator cone - appears when burning up fuel additives or engine oil. They melt when the engine is running with maximum loads, forming a conductive layer, as a result of which ignition skips may occur. After a large number of trips for short distances, it is not recommended to immediately exploit the engine with the maximum power.

The layer of oil on the cone of the insulator and the electrodes is precipitated when the piston rings are deposited, the valve sleeves or oil-circulation caps.

Output

If the appearance of the Ignition Candles of the Daewoo Nexia without deviations, but the engine operation is broken, possibly candles are defective. Invisible cracks in the insulator when starting a cold engine can be filled with fuel, which assigns a spark. In addition, spar formation can be broken under pressure, despite the fact that the candle is open normally outdoors.

Nexia, worries every car owner, as they relate to consumables, which, according to the technical regulations, the model must be changed every 10,000 km. And to their selection should be due to responsibility. The candle bought without taking into account the manufacturer's instructions is often turning to the "cat in a bag", which leads to unpleasant consequences. It becomes the main reason for the poor engine launch at the slightest frost, leads to an increase in fuel consumption, negatively reflected on the dynamics of the machine.


Which candles are optimal for DEU Nexia 8 valves, suggests the manufacturer itself. "Native" for the machine with a motor SONS, coming from the conveyor, are products of production of the famous Japanese company NGK. The main advantage of the Corryon products that dominates the ignition candles since 1936 is the maximum compliance of the candle parameters by the main characteristics of the combustion chamber. To which include:

  • working temperature;
  • pressure;
  • type of gasoline.

Therefore, when choosing a candle for service replacement, first of all, attention should be paid to the marking.

The calil number and the gap between the electrodes that are constantly in the field of high temperature and pressure are the most important indicators of conformity. It is from them that the optimal ignition rate of the mixture and quick start depends.

Car Manufacturer - Daewoo Motor Corporation strongly recommends for an 8-valve motor SONS NGK R BPR6E spark plug, running under the original number 94837756. This is a win-win version for gasoline engines operating in normal mode without overload.

Bump6e beep decoding reads:

  • BP - the diameter of the thread is 14 mm, the size of the 6-face key is 21 mm.
  • R - denotes that the candle is equipped with a radio intermission system.
  • 6 is the most magical caliper.
  • E - shows that the length of the threaded part is 19 mm.

The absence in the marking of the distance parameter between the electrodes implies that the gap corresponds to the brand standard and is 0.7-0.8 mm.

What candles can still be put on Daewoo Nexia?

CHAMPION RN9YC mixture devices produced by the American concern of the same name are an excellent option for replacing NGK R BPR6E and protrude under the same number 94837756. And although they have some differences in marking, in fact, they are the same NGK:

  • N - indicates the same diameter of the thread and the key size is 14 mm and 21 mm;
  • 9 - the value of a gauge;
  • Y and C - emphasize the characteristic signs of the brand. Y reports that the sample of the candle insulator goes beyond the housing. C - that its core is covered with copper.

Many Daewoo Owners Nexia with an 8-valve engine chosen and spark plugs of the famous German manufacturer Bosch. Doubt in their quality does not have to. They are very similar to Champion RC9YC. The only difference between brands is a calic number that in Bosch candles is 7 units.

Iridium or nickel? What candle to buy?

As for the question, which candles are better to buy Nexia, iridium or ordinary, it is an individual choice of each driver. Progressive iridium candle works longer, it is necessary to change it less often, but its cost is much higher than usual. Any innovation, like a medal, has 2 sides. But whatever the candle, nickel or iridium, the same requirement is put forward to it: a gallinal number should be within 6-9 units.

Everyone in this life everyone chooses for himself. Choose, buy for your favorite the best candles and travel with pleasure! Sustainable sparks and easy start!
