Why did Buick Hideo 1.0t start the stirrup automatically?

You may hear the sound of starting stirrups during cold start, because the oil efficiency decreases. After a period of use, the efficiency of the oil will gradually decline, and it is normal for the sound to become louder. If the oil is not suitable, it is likely to cause the engine to make a lot of noise. If the noise is relatively high when idling and the vehicle is idling at a high speed, it is likely that the throttle, air intake and nozzle of the vehicle need to be cleaned, especially the throttle.

The motor makes a lot of noise.

When the stator rubs against the rotor, it will produce harsh rubbing sound, which is mostly caused by bearing failure. If damaged, check and replace the bearing. If the bearing is not broken and it is found that the bearing is in the inner ring or the outer ring, the bearing and the end cover can be inserted or replaced. ? The blade hits the shell or there are sundries, making a crash sound. The blades should be calibrated and sundries around the blades should be removed.

The motors run out of phase, and the roar is particularly loud. Turn off the power, then turn on the power to see if it can start normally again. If it can't start, the fuse may be blown. When the first phase of the switch and the contactor contact are not connected, the non-full phase operation will also occur. When the bearing is seriously short of oil, the bearing chamber will hiss. Bearings should be cleaned and new oil should be added.
