15 What is the engine jitter when KIA k3 is idling?
The causes of car jitter:
1, too much carbon deposit. If the carbon deposit in the engine cylinder is serious, it will cause the spark plug to be blocked and the valve to be blocked, which will directly lead to the idling jitter of the car. If the acceleration ability of the car is not as good as before and the jitter is lasting, then you can consider cleaning the engine cylinder.
2. Oil supply system failure. Unstable oil pressure will easily lead to unstable mixture concentration, which will not only cause jitter, but also cause unstable idle speed. You can consider replacing the gasoline filter first. After all, the filter element may be blocked after being used for a long time, and then check the oil pressure that does not pass through the gasoline filter. If it is not normal, there may be something wrong with the oil pump.
3, the engine pad aging this is also a very common cause of jitter. If the engine jitter of your car is getting worse and worse, but the power is not weakened, you can consider whether it is the problem of the foot pad.
4. Lack of cylinder and misfire This is the most common cause of engine jitter, even one of them. The problem lies in the ignition coil or spark plug of the engine. If there is something wrong with the ignition coil or the spark plug fails to catch fire for some reason, then the car will shake.
Extended data:
Vehicle maintenance:
1. When the cold car starts, pay attention to let the car run for one and a half minutes to give the car a warm-up time. At first, the internal temperature of the engine could not reach the normal working temperature-it was normal for the water thermometer to show 90 degrees. The car will shake, the engine will ring, and the tachometer will be slightly higher-normal means 600 rpm to 900 rpm. If the engine is started in this situation, it is easy to cause carbon deposition in the engine, because the engine is not fully burned at low temperature).
2. Don't shift gears when driving, and shift gears in time when the engine is shaking. (flameout will lead to excessive pressure on the engine, insufficient power, incomplete combustion of gasoline, and carbon deposition in the nozzle, which will affect the service life of the engine.
3. Chassis protection. Chassis is a part of the car body that is very close to the ground, and it is also a part that is easily damaged by ground objects during driving, so it is necessary to check the chassis frequently to avoid excessive damage to the chassis by foreign objects.
4. Oil should be replenished in time. If there is no obvious deterioration of the engine oil during inspection, it should be found whether there is oil leakage, and if there is, it should be eliminated and the engine oil of the same level should be replenished in time.
5. The filter element of air cleaner is responsible for blocking the foreign matter attached in the outside air and ensuring that the engine cylinder has fresh, clean and sufficient air, which is a very important part of the "breathing system" of the automobile. If the filter element is not clean, it will naturally reduce the intake of outside air, making it difficult for air and exhaust gas generated by automobiles to circulate alternately, which will affect the normal injection and combustion quality of gas. In this case, the fuel consumption will increase relatively, which is not conducive to the normal operation of the car. It is necessary to replace and clean the air filter in time.
6. The tires should be replaced at 30,000 kilometers, with the front wheel turning to the rear wheel and the rear wheel turning, which can prolong the service life of the tires.
