High-pressure ignition coil broken engine symptoms?

1. There are three performances when the engine ignition coil breaks: first, when the engine is idling, the body shakes obviously; second, during the driving process, when the speed is below 2500rpm, the body shakes obviously and the acceleration is weak; open the engine cover, observe the running engine, and find that the engine is clear Show jitter.

2. The high-pressure ignition coil is broken. The engine symptoms are as follows: in the idling state, the body shakes obviously.

3. The high-voltage ignition coil is broken. The engine has the following symptoms: when idling, the body shakes obviously.

4. If the ignition coil is broken, there will be some engine shaking, increased fuel consumption, power decrease and other phenomena. Engine shaking: Once the ignition coil is damaged, and the spark plug cannot break through the ignited combustible mixed gas, it is very easy to cause the engine to lack of cylinder, resulting in violent jitter.

High-pressure ignition coil broken engine symptoms

High-pressure ignition coil is broken. The engine has the following symptoms: when idling, the body shakes obviously.

Mild: car shaking, unstable idle speed, weak departure Serious: unable to igniteNoun explanation: Ignition coil There are two sets of coils in the usual ignition coil, the primary coil and the secondary coil.

Engine jitter: Once the ignition coil is damaged, and the spark plug cannot break through to ignite the combustible mixed gas, it is very easy to cause the engine to have a missing cylinder, resulting in violent jitter. If there are too many missing cylinders or the two adjacent working cylinders are missing at the same time, the engine is likely to fail to start normally.

The most obvious symptom of car ignition coil failure is the lack of cylinder in the engine. When idling, the engine may have a clear burst sound, which is most obvious on the exhaust pipe with your hand, accompanied by engine tremor and shaking. There are also the following specific symptoms: in idle time, the body trembles obviously.

Generally, the damage of the ignition coilIt may be because the engine is not working, the engine is overheated, the spark plug electrode gap is too large, the high-voltage line is broken, the ignition coil model is wrong, the ignition coil is of poor quality, etc. After the ignition coil is damaged, there will be symptoms such as engine shaking, power loss, car failure to ignite, and carbon accumulation.

The ignition coil is always burned out? What's going on

1. The reason why the ignition coil is always burned has been found. The ignition coil is the core component of the car ignition system. If the car wants to start, it cannot be separated from the ignition coil. In general, the ignition coil is composed of the main coil, the secondary coil, the magnetic core, the switch triode and other auxiliary originals.

2. The main reason for the burning of the ignition coil is the aging breakdown of the insulation or the damage of the switching triode. A large spark plug gap will cause the main coil load to be high and the insulation layer will age rapidly.The small gap of the spark plug will lead to a large discharge current, a high heating of the secondary coil, and a rapid aging of the insulation layer.

3. What's going on? The ignition coil that was just installed burned out not long after, replaced with a new one, and burned out again? The ignition coil is one of the key parts of the engine ignition device, which provides sufficient energy for the spark plug to generate enough electric sparks and improve the working performance of the engine. The ignition coil is mainly composed of primary coil, secondary wire solid and iron core and other parts.

How often should the engine's ignition coil be changed

The ignition coil is generally replaced once every 100,000 kilometers. As the core component of the engine ignition system, the ignition coil mainly plays the role of intermittently converting the low-voltage electricity of the vehicle into high-voltage electricity.

The ignition coil is generally replaced every 100,000 kilometers. When the engine is running, there is often a high-voltage pulse current of tens of thousands of volts on the ignition coil. Because it works in a high temperature, dusty and vibrating environment for a long time, it will inevitably age or even be damaged. If it is not replaced in time, it will affect the working performance of the engine.

Generally 100,000 publicThe ignition coil needs to be replaced once. When the engine is running, there is often tens of thousands of volts of high-voltage pulse current on the ignition coil. Because it works in a high-temperature, dusty and vibration environment for a long time, it will inevitably cause aging or even damage. If it is not replaced in time, it will affect the working performance of the engine.

The performance of the engine ignition coil is broken

1. [Pacific Automobile Network] Symptoms of the broken ignition coil of the car: in the idle state, the body shakes obviously; during the driving process, when the speed is below 2500 rpm , the car body has obvious shaking and weak acceleration; open the engine cover, observe the running engine, and find that the engine has obvious shaking.

2. After the ignition coil is broken, the car is in the idling state, and the body shakes obviously;Observing the outlet of the exhaust pipe, there is an obvious intermittent flow of exhaust gas discharged by the car. At the same time, the exhaust pipe shakes heavily, and the sound of "tutu" can be clearly heard.

3. The phenomenon of automobile ignition coil failure is: engine shaking: once the ignition coil is damaged, and the spark plug cannot break through the ignited combustible mixed gas, it is very easy to cause the engine to have a lack of cylinder, resulting in violent shaking.

4. There are the following three performances: First, in the idling state, the body shakes obviously. Observing the outlet of the exhaust pipe, there is an obvious intermittent flow of exhaust gas discharged by the car. At the same time, the exhaust pipe shakes heavily, and the sound of "tutu" can be clearly heard.

5. The performance of the engine ignition coil is broken. The performance of the engine ignition coil is broken in the idle state.During the driving process, it is clear in observing the engine shaking: First, if the vehicle is in the idle state, if the car body shakes obviously.

6. The most obvious symptom of car ignition coil failure is the lack of cylinder in the engine. When idling, the engine may have a clear burst sound, which is most obvious on the exhaust pipe with your hand, accompanied by engine tremor and shaking. There are also the following specific symptoms: in idle time, the body trembles obviously.
