The phenomenon of spark plug leakage, what is the effect of spark plug leakage, is the spark plug le

When the owner finds that the top of the spark plug is scarred or damaged, and the electrode is melted or ablated, it indicates that the spark plug has been destroyed, and the spark plug should be replaced. During the replacement process, the owner can check the symptoms of spark plug ablation and the change in color.

Symptom 1: The electrode is melted and the insulator is white.

Diagnosis: This phenomenon indicates that the temperature inside the combustion chamber is too high. This can be caused by too much carbon build-up in the combustion chamber, which causes the valve clearance to be too small, which can further lead to overheating of the exhaust valves or poor cooling of the unit.

When the spark plug is not tightened according to the specified torque, the electrode will melt and the insulator will appear white.

Symptom 2: The electrodes are rounded and the insulator is scarred.

Diagnosis: This indicates that the engine is prematurely ignited, which may be caused by too early ignition time or too low octane number of gasoline and high calorific value of spark plugs.

Symptom 3: Chipping of the tip of the insulator.

Diagnosis: In general, knock combustion is the main cause of insulator rupture. Ignition too early, low octane number of gasoline, and high temperature in the combustion chamber can all lead to engine knock combustion.

Symptom 4: Gray-black streaks on the tip of the insulator.

Diagnosis: The appearance of such streaks indicates that the spark plug has leaked and the owner needs to replace it with a new part unconditionally.

What are the symptoms of a broken spark plug, these four points tell you whether the spark plug is different.

The spark plug is an important component of the engine, and it should be checked and maintained from time to time. Because it is not difficult to check and replace the spark plugs, there are many car owners who like to do it themselves. However, these car owners basically ignore the installation torque of the spark plug hole, resulting in the spark plug leakage.

What is the effect of a spark plug leak? Spark plug leakage will cause engine weakness, unstable idling, easy stalling at high speed, increased fuel consumption, and even the engine can not start, which will seriously lead to spark plug failure and engine damage. Unless you are an experienced master who can judge whether the spark plug has reached the specified torque based on the feeling alone, it is best to use a torque wrench to install the spark plug.

Generally, the torque of the spark plug is about 20 N·m.

As the core component of the engine, the spark plug is an important part of the ignition system of the car, and the working environment of the spark plug is very harsh and fragile. It is closely related to the fuel consumption of the car and whether it runs smoothly. Generally speaking, the service life of a spark plug is about 30,000 kilometers, and the service life of the spark plug is 6 to 90,000 kilometers.

Do not arbitrarily extend the need to choose the opportunity to replace, if the owner finds that the vehicle has significantly increased fuel consumption, then it is likely that the spark plug is damaged, and it is recommended to replace it immediately.

The spark plug is a key component of the engine and should be checked and maintained frequently. Since it is not a difficult problem to inspect and replace spark plugs, many car buyers like to do it themselves. However, most of these car buyers ignore the installation torque of the spark plug, resulting in spark plug air leakage.

What are the hazards of spark plug leakage?

Spark plug leakage will cause the engine to be weak, idle shaking, fast and easy to stop the fire, fuel consumption increases, and even the engine can not start, which is more serious to cause the spark plug common stool branch failure, engine damage serious hazards. Unless you are a master with work experience, you can tell whether the spark plug has reached the required torque just by touch, otherwise the best match is to use a torque wrench to install the spark plug. Generally, the torque of the spark plug is always at 20N

Generally, it is due to the spark plug is not installed in place, resulting in poor sealing, there will be air leakage, or spark plug damage, this situation will occur, and it is necessary to do some inspections in time, repair thoroughly, and overhaul and maintain in time to ensure stable, comfortable and safe driving.

The spark plug (spark plu gs), commonly known as the nozzle, is used to send a pulse high-voltage electrical discharge from the high-voltage wire, break through the air between the two electrodes of the spark plug, and generate an electric spark to induce the mixed gas in the cylinder. The main types are: quasi-type spark plugs, edge body protruding spark plugs, electrode type spark plugs, seat type spark plugs, polar type spark plugs, surface jump fire type spark plugs, etc.

The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber, and generate an electric spark to ignite the mixture, and cooperate with the ignition system and oil supply system to make the engine work, which determines the performance of the engine to a large extent.

There are hundreds of spark plug types, but one standard spark plug cannot be used in all engines. Due to the different operating characteristics of various engines, there is no one standard spark plug that can be adapted to all engines. Therefore, it is necessary to select the appropriate spark plug according to the characteristics of the engine.

Generally, it is because the spark plug is not installed properly, resulting in poor sealing, air leakage, or damage to the spark plug. It is necessary to do some inspections in time, repair thoroughly, and repair and maintain in time to ensure stable, comfortable and safe driving.

The spark plug, commonly known as the burner, is the use of pulse high-voltage electrical discharge from the high-voltage line to penetrate the air between the two electrodes of the spark plug to produce an electric spark point gas mixture in the gas cylinder. The main types are: quasi-spark plugs, flange convex spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, surface spark plugs, etc.

The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber, generate an electric spark to ignite the mixture, and together with the ignition system and the oil supply system, the engine does work, which largely determines the performance of the engine.

There are hundreds of models of spark plugs, but one standard spark plug cannot be used for all types of engines. Due to the different operating characteristics of various engines, there is no one standard spark plug that can be adapted to all engines. Because of this, it is necessary to select the appropriate spark plug according to the characteristics of the engine.

If the spark plug leaks, there will be gray-black streaks on the top of the insulator. This is because the spark plug is not tightened, resulting in air leakage and the insulator being blown black by high-temperature and high-pressure gases. Severe ablation, scarring at the top of the spark plug, damage, or electrode melting and ablation are all signs that the spark plug is damaged and should be replaced.

Spark plugs are an important part of an automotive's ignition system. If the spark plug is damaged, it will directly cause many problems such as leakage, increased fuel consumption, and decreased power. The main problem is the difficulty of ignition, which affects the normal use of the vehicle.

When it is found that the spark plug is heavily aged or damaged, it must be replaced in time. If the spark plug is not replaced for a long time, it will affect the ignition effect of the car, the start will be blocked, and carbon deposition will occur after long-term use. There is a limit to the voltage that the ignition coil is capable of supplying.

Even if the spark plug is in normal use, the need for voltage to break through the spark plug gap increases with the loss of the spark plug electrode. As a result, in the case of rapid acceleration, high speeds, or heavy loads, fires can occur, causing vehicle shaking, acceleration difficulties, and fuel waste.

When the spark plug needs to be replaced, it is when all kinds of abnormal problems arise. For example, the spark plug electrode melts early, and the insulator turns white, indicating that the combustion chamber temperature is high, the combustion chamber carbon deposit, the valve clearance, etc. As a result, the exhaust valve is heated or the cooling device is not working properly, and the spark plug is not tightened according to the specified torque.
