What's wrong with the start jitter of Sega cold car?

The following are the reasons for the start-up jitter of Sega cold car: 1. Carbon deposition in the intake system, that is, there is a large amount of colloidal carbon deposition near the valve seat and around the idle motor, which causes the mixture to be too rich and too lean. Will form the phenomenon of idle jitter, especially when the cold car starts. 2. The throttle valve is too dirty, because there is too much colloidal carbon or dirt around the throttle valve plate, and the cross-sectional area of the air passage will change, which makes the control unit unable to accurately control the idle intake, resulting in the mixture being too rich or too thin. Extended data:

1, the phenomenon that the cold car is not easy to start in the morning is related to many reasons, such as excessive carbon deposition in the intake system such as throttle valve and idle valve, low fuel pressure, poor atomization of fuel nozzle and poor working performance of ignition system. , which is directly related to the working performance of spark plugs, high-voltage lines and ignition coils. 2. In addition, if the working performance of the idle control valve itself is not good, and the working performance of related sensors is not good, it will also lead to the phenomenon that the cold car is not easy to start, such as water temperature sensor, air flowmeter or manifold pressure sensor. When the car is cold, the oil sinks to the bottom. If the car is not hot and the engine oil is not circulating, it will damage the engine. Car owners should never drive violently immediately after starting. If you have enough time, it's okay to drive at idle speed or low speed for a while, so that your car can better enter the working state.
