It is said that there is a lack of cylinders, what should be replaced, and what should I do if the c

1. Fault judgment:

It is usually manifested as: the engine is found to work abnormally or the power is insufficient, the engine works unevenly at high, medium and low speeds, and the rhythmic vibrating muffler discharges black smoke and discharges guns. The lack of cylinder in the engine can lead to large fuel consumption, black smoke, weakness, horsepower decline, the vehicle cannot increase speed, serious shaking, and increased driving noise.

And it is very bad for driving safety. Especially on the road section that needs to be sloped, the engine load of the vehicle with a lack of cylinder increases, the body shake is more obvious, and it is very easy to have an instantaneous dead fire.

Second, the lack of cylinder operation of the engine will bring great harm

1.The speed and power of the engine decreased.

2.Increased fuel consumption and emissions of pollution.

3.Aggravate the wear of running parts and shorten the service life of lubricating oil.

Third, the maintenance method: first check the circuit fault, and then check the valve tightness (cylinder compression ratio), if there is no problem with the above inspection, it is more troublesome, belongs to mechanical aging or damage, need to be overhauled.

1. Circuit failure: spark plugs, cylinder wires, ignition coils, etc. are damaged, and it is easy to lack cylinders. You can use the broken fire to determine which cylinder parts are damaged, and replace the damaged parts.

2. Oil circuit: the fuel injector is blocked, and the fuel injector line is short-circuited or broken. The oil cut-off test is used to detect the fault point and carry out maintenance.

3. Mechanical failure: the internal piston, connecting rod, piston ring, piston pin, etc. of the engine are faulty, which are generally accompanied by obvious abnormal noise, and obvious metal chips can be seen when detecting the oil. Engine overhaul.

Petrochemical and petroleum clean the underground oil tank once in February, who added the oil before cleaning, how do you guarantee that the fuel is okay? How to determine that the oil circuit is not dirty and the combustion is not good, and the long-term bad carbon deposition caused by the problem of carbon deposition is brought about? Repair is the method of elimination, do not rule out any possible problems, clean the oil circuit, add 3 divisions of fuel additives to run three tanks of oil, and your problem will probably be solved.

Because you have changed a lot of accessories many times, it is not a matter of accessories, you can learn from it.

There are three main reasons for the lack of cylinders in automobiles: one is the engine cylinder liner and piston rings, which have a large wear clearance. The second is the wear of the injector, resulting in poor fuel atomization. The third is the ECU of the engine computer board, which is caused by the lack of cylinders.

Hello, frequent lack of cylinder, check the following places, 1, ignition coil, spark plug, 2Gasoline pressure and fuel injectors, 3Mechanically, the valve seal is poor.

What does it mean that the engine is "missing cylinders"?

How do you know that your car is missing cylinder burning, and the factors that affect the lack of cylinder in the car are, the spark plug has reached the service life, the gap is increased and can not jump the fire, and there is too much carbon accumulation in your car that causes the fuel injector to be blocked and unable to inject fuel, it is recommended that you go to the 4S shop to check It is recommended to do a big maintenance of the car, and replace the spark plug, cylinder line, clean the fuel injector, and check the fuel pressure The cost of cleaning the fuel injection may be higher Thank you for stepping on it.

The key is to see whether it is a lack of fire, lack of oil, or lack of cylinder pressure caused by the lack of cylinder, the first two reasons are easier to repair, if there is no cylinder pressure, you can only remove the cylinder pressure to further analyze the cause of the failure, generally the cylinder pressure is not enough is the probability of valve leakage.

It depends on whether it is an occasional failure or a long-term one, if it is occasional, the problem is not big, if there is a long-term lack of cylinder, it is better to repair and deal with it as soon as possible. There are many reasons for this, and you need to check it out.

First of all, check the circuit fault, and then check the valve tightness (cylinder compression ratio), if there is no problem with the above inspection, it will be more troublesome, it is mechanical aging or damage, and it needs to be overhauled.

The lack of cylinders in automobiles is mainly caused by the failure of the ignition system of the automobile engine. The specific replacement parts are the ignition coil and spark plug! The probability of the ignition coil being bad is greater than that of the spark plug!

Go to the car 4S shop (**high), go to the car fast repair shop (**relatively low), yourself**, and then go to the 4S shop (only charge manual fees, the most affordable)!

The problem comes from poor combustion, which causes this phenomenon.

If it is a lack of cylinder, the obvious phenomenon is jitter, and there is a fault light on, you can go directly to the 4S shop and use the computer detector to read the fault**. In addition, you can also go to the car quality network for related complaints, as the largest complaint in China, the car quality network itself has a very large influence and the strength to solve the problem, you can go to the car quality network for complaint feedback.

The lack of cylinders in the car mainly refers to the engine has one or more cylinders that do not work normally, which is usually manifested as abnormal engine work or insufficient power, and the engine works unevenly and rhythmically shakes at high, medium and low speeds, and the muffler discharges black smoke and fires.

Causes of lack of cylinders in automobiles: The causes of engine cylinder shortage mainly come from the ignition system and fuel injection impulse system. If the contacts of the distributor cover of the ignition system are severely ablated, there will be a jumper, most of which occurs between the corresponding stigma heads on the cover, and the idle speed is seriously high and low, the power drops seriously, and the vehicle feels like a severe asthma attack.

The failure of the ignition coil can also lead to the lack of cylinder, and often the problem of the ignition coil will cause serious ablation of the distributor cover. After the ignition coil has a problem, it is also the most likely to have a serious power drop, and the car will be extinguished in an instant. The most likely to lead to the lack of cylinder is the spark plug, many problems are related to the spark plug, sometimes the ignition problem can also make the spark plug work for a period of time, the electrode discharge part can directly cause the cylinder not to work due to ablation.

The spark plug belongs to the medium and high calorific value type, and the selection of the hot field with low return value is also easy to cause more carbon deposits, and the spark plug has too much carbon deposit, after the fuel is wetted, it is equivalent to the parallel shunt resistance between the spark plug electrodes, resulting in spark plug leakage, and the flashing fire is too weak, and the spark plug can not work when it is serious, so it is naturally easy to cause a lack of cylinder.

Missing cylinders in cars are caused by damage to the ignition coil or spark plug. If the cylinder is missing, simply locate the ignition coil damaged by the hailist or replace the spark plug. Spark plugs and ignition coils are important components of the engine ignition system, and spark plugs are wearing parts that need to be replaced regularly.

There is an electrode on the spark plug. This electrode can be discharged.

At the end of the compression stroke, the electrodes of the spark plug can release an electric spark that ignites the combustible mixture in the cylinder.

The combustible mixture pushes the piston downwards and powers the engine.

However, as the time of use increases, the electrode gap of the spark plug will become larger and larger, resulting in a weakening of the ignition energy.

If the spark plug is not replaced for a long time, it may cause the spark plug to fail to ignite.

The ignition coil is connected to the spark plug, and its function is to increase the voltage.

If the voltage is not high enough, the spark plug will not ignite smoothly.

Although the ignition coil is not a wearing part that needs to be replaced regularly, the ignition coil can be easily damaged when it runs in a high-temperature environment for a long time.

If the ignition coil is damaged, the spark plug cannot release the spark.

If the ignition source is damaged or the coil is damaged, it needs to be replaced immediately.

It is recommended that you replace the spark plugs regularly when you are using the car.

Millions of car purchase subsidies.

It is recommended to go to the 4S store to check it out.

1. The main reason for the lack of cylinder in the engine and its maintenance method: the main reason for the lack of cylinder comes from the ignition system and fuel injection system.

1) The spark plug pin of the ignition system does not skip the ignition, the high-voltage coil is damaged and cannot produce high-voltage electricity, the high-voltage coil relay is damaged, and it is possible that the high-voltage coil does not ignite due to ECU failure.

Maintenance method: In this case, the spark plug should be replaced in time according to the maintenance manual, and the high-voltage coil resistance value should be detected by a universal meter (1-4 ohms for the primary stage, and 8000 to 16000 ohms for the secondary stage). Relay damage can be detected with a multimeter, or you can hear whether there is a "da-da" sound in the ignition, which means normal, otherwise it may be damaged.

The detection of ECU can be checked by a professional decoder in a 4S store.

2) The fuel supply pressure of the fuel injection system is insufficient, the oil circuit is damaged, the oil tank is too worn out, the gasoline filter is blocked, the pressure of the high-pressure oil pump is insufficient, the fuel injector is blocked or the fuel injection atomization effect is not good or the ejector pin is worn too much, resulting in the fuel injector dripping is that the gasoline vapor in the cylinder is too thick and wets the spark plug, resulting in the spark plug not jumping.

Maintenance method: use the oil pressure gauge to detect whether the oil pressure is sufficient; Lift the car up and observe if the oil pipe is worn out and leaking. Replace the gasoline filter, check whether the tank oil pump and high-pressure oil pump are overworn, and replace them in time.

Clean or replace the fuel injector in time according to the use of the fuel injector (every two major maintenance cleaning, 200,000 kilometers to replace).

2. If the engine is missing due to insufficient cylinder pressure due to cylinder pulling, excessive valve clearance, valve deformation and pinning, and insufficient cylinder pressure caused by the plane of the cylinder head, it should be overhauled. Because the wear and tear of these parts has broken the original state of the engine, it is necessary to disassemble and repair it.

Pacific Automobile Network] The method of engine cylinder maintenance: 1. The fuel injector is blocked, and the short circuit or open circuit fault of the fuel injector line will lead to the lack of cylinder in the engine. 2. If the ignition parts such as spark plugs and ignition coils are lost, the lack of cylinder of the engine will be more likely to occur.

What are the most common faults of car engine cylinder missing, how much does it cost to repair a car engine cylinder, and what are the most common faults when encountering a car engine cylinder missing, and how much does it cost to repair a car engine cylinder? Do you have any good ideas?

Asked by: Ram Wei'e|2022-07-2833870 Write Please first log in the reason for the lack of cylinder in the best engine:

1. The piston ring of the engine cylinder liner is worn with a large gap, the intake and exhaust valves are not closed tightly, and the valve oil seal leaks resulting in insufficient cylinder pressure.

2. Poor fuel atomization caused by injector wear, increasing or decreasing fuel volume, or even lack of cylinder caused by no fuel injection.

3. If it is a high-pressure common rail engine, there may be a lack of cylinder caused by problems with the ECU of the engine computer board.

4. There is a main reason for the lack of cylinder in the engine is whether the quality of the diesel is passed, and too many impurities will cause wear and tear of the engine, so remember to fill regular fuel, and usually maintain the engine, which can greatly reduce the probability of lack of rubber cylinder.

The most common engine cylinder is caused by ignition system failure, the ignition system is mainly divided into spark plugs and ignition coils, all of which are wear parts, if it is because of the lack of cylinders caused by spark plug damage, then the repair needs about 500 pieces (4 spark plug processing time costs), if it is because of the ignition coil damage caused by the lack of cylinders, then the repair needs about 700 pieces (4 ignition coil processing time costs).

The consequences of the lack of cylinders and non-repair of the engine: 1. The oil content of the exhaust gas is seriously exceeded, and the three-way catalytic converter will burn the oily exhaust gas, which will inevitably accelerate the deterioration of the catalytic converter; 2. The vibration amplitude of the engine increases, accompanied by abnormal sound, the acceleration is weak and the exhaust pipe shakes obviously, there is an obvious intermittent feeling when the exhaust is discharged, and the amplitude will be reduced when stepping on the accelerator when the neutral gear is stepped on; 3. The cylinder refers to the cylindrical metal parts that guide the piston to carry out linear reciprocating motion in the cylinder. The working fluid converts thermal energy into mechanical energy by expansion in the engine cylinder; The gas is compressed by a piston or an eggplant in the compressor cylinder to increase the pressure.

The housings of turbines, rotary piston engines, etc., are also commonly referred to as cylinders.
