What happened to the slow start of the idle meter after the startup of Qichen R50?

Throttle oil accumulation and throttle carbon accumulation, and the air inlet is too dirty: with the extension of automobile service time, the air inlet of the automobile will be blocked, and there is carbon or engine oil in the throttle. The phenomenon of unstable or even low idle speed is caused, and the throttle affects the intake due to carbon deposition, and the idle speed is also low when the car starts.

Introduction of other reasons

Spark plugs caused by individual spark plug failures are too weak, and carbon deposition will also occur with the extension of automobile spark plugs. When the carbon deposition is serious, the spark plugs on individual cylinders are weak, which will affect the performance of the vehicle and lead to the low idle speed of the vehicle. It is recommended to clean or replace the spark plug in time.

When the idle speed control valve fails and the related sensors of the automobile have problems, the automobile does not have the correct air-fuel ratio. The common problem is that the water temperature sensor, oxygen sensor and throttle position sensor fail, resulting in high fuel consumption and low idle speed.

The idle speed of the vehicle can be adjusted by opening the throttle and supplying fuel at idle speed. Generally speaking, if the vehicle is in the idle range and does not shake, its idle speed is the best.

Usually called hot car, it refers to the process from the idle state of cold car to the idle state of engine at normal working temperature. Generally, if the idle speed of a car is unstable, it is caused by the following reasons. The first is caused by dirty, worn and incorrect installation of mechanical parts; Second, the engine electronic control system is abnormal.
