宝马在等红灯时会有轻微抖动是怎么回事?

  一个朋友问:“B48等红灯的时候,偶尔会有轻微的抖动,这是正常的吗?”这里有一个正式的回复,同时下面说到红绿灯晃动的问题,有兴趣的朋友可以理解一下。
  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.
  首先,发动机怠速运转,会带动车辆振动,这是不可避免的事实。此外,发动机本身也会对抖动产生影响,如三缸机肯定不是六缸机,十二缸机要稳定。如果再加上发动机的纵向,更容易发生左右摆动,并会加剧抖动现象。虽然厂家会采取各种技术来平衡这种抖动,但也只能减少,不能消除。
  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.
  其次,摇这个东西因人而异,敏感的人会感觉得到,神经大的朋友可能不在乎,自然感觉不到。
  Secondly, shaking this thing varies from person to person, sensitive people will feel it, nervous friends may not care, naturally not feel it.
  第三,许多业主都讨厌自动起停,拿起车所以她要去刷隐藏,或者在车里被关闭,因此导致很多次,如交通信号灯是D装置制动状态,发动机功率是恒定的输出,传输系统不中断,电力流向车轮,刹车踩死,然而,汽车结束了,所以比平时更容易抖动。
  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.
  因此,基于以上几点,只等红绿灯偶尔轻微晃动,概率大是正常现象。
  Therefore, based on the above points, it is normal to only wait for the traffic light to shake slightly occasionally.
  PS: D齿轮上的刹车变矩器,是齿轮箱的测试,尤其是双离合器的齿轮箱,所以最好少用点,实在不想挂P,那就挂n,不要懒得动手指!
  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!

  这里的抖动和这里有点不同,如果你一直在等红绿灯,而你有轻微的抖动,它肯定是最近增加了;还是以前等红绿灯没感觉,现在有了。所以,我们可以假设飞行器有问题。具体原因有很多,下面是一些常见的:
  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、怠速过低:等待红绿灯,车辆处于怠速状态。
  1. Low idle speed: wait for the traffic light and the vehicle is idling.
  2. 进气积碳:进气阀、进气阀、节流阀积碳会使进入气缸的混合气浓度变薄,导致发动机功率不足,引起振动。
  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、火花塞过碳或不久就要投入使用:造成点火能量不足,发动机功率自然不足,造成抖动。
  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. 如果空调一关,车就正常了,可能是压气机出了问题,比如压气机皮带松紧不当。
  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.
