A friend asked, "is it normal for B48 to vibrate slightly occasionally when waiting for the red light?" here is a formal reply. At the same time, I will talk about the shaking of the traffic light. Interested friends can understand it.
First of all, idling engine will drive vehicle vibration, which is an inevitable fact. In addition, the engine itself will also affect the jitter, for example, the three cylinder engine is certainly not a six cylinder engine, and the twelve cylinder engine should be stable. If combined with the longitudinal direction of the engine, it is easier to swing left and right, and will aggravate the shaking phenomenon. Although manufacturers will adopt various technologies to balance this jitter, it can only be reduced and cannot be eliminated.
Secondly, shaking this thing varies from person to person, sensitive people will feel it, nervous friends may not care, naturally not feel it.
Third, many owners hate to start and stop automatically. They pick up the car, so they have to brush it and hide it, or they have to be shut down in the car, which leads to many times. For example, the traffic signal light is the braking state of D device, the engine power is a constant output, the transmission system is not interrupted, the power flows to the wheels, and the brakes are stepped on. However, the car is over, so it is easier to shake than usual.
Therefore, based on the above points, it is normal to only wait for the traffic light to shake slightly occasionally.
PS: the brake torque converter on the D gear is the test of the gearbox, especially the double clutch gearbox, so it's better to use less. If you really don't want to hang P, hang n. don't be too lazy to move your fingers!
Waiting for the traffic lights to shake again
The jitter here is a little different from here. If you've been waiting for the traffic light and you have a slight jitter, it must have increased recently; or it didn't feel like waiting for the traffic light before, now it does. So we can assume that there is a problem with the aircraft. There are many specific reasons. Here are some common ones:
1. Low idle speed: wait for the traffic light and the vehicle is idling.
2. Carbon deposit in intake air: carbon deposit in intake valve, intake valve and throttle valve will make the mixture concentration into the cylinder thin, resulting in insufficient engine power and vibration.
3. The spark plug is too carbon or will be put into use soon: the ignition energy is insufficient, the engine power is naturally insufficient, causing jitter.
4. If the air conditioner is turned off, the car is normal. Maybe there is something wrong with the compressor, for example, the belt of the compressor is not tightened properly.
遇到这个问题,作为车主可以先怠速是否高于650 RPM,然后思考多长时间没有清理碳和火花塞的积累生活,通常可以猜测,如果你不知道,那么只能去4 s。
If you encounter this problem, as a car owner, you can first idle for more than 650 rpm, and then think about how long you haven't cleaned up the carbon and spark plug accumulation life. You can usually guess that if you don't know, you can only go for 4 seconds.
