Is it necessary to clean the throttle?

When the engine is abnormal, it is necessary to clean the throttle. If the throttle valve is too dirty, there will be too much colloidal carbon or dirt around the throttle valve plate, and the cross-sectional area of the air passage will change, which will make the control unit unable to accurately control the idle intake, resulting in the mixture being too rich or too thin, which will lead to the car shaking.

There are no phenomena such as unstable idle speed, engine jitter, obvious increase in fuel consumption, and weak acceleration, and there is no need to clean it. But if this happens, it is necessary to clean the throttle in time.

Extended data:

The dirty throttle is mainly caused by the structural problems of the engine, and the high temperature and high pressure gas in the combustion chamber will enter the crankcase. In order to prevent waste gas from polluting the engine oil and shorten the service life of the engine oil, a part of high-temperature crankshaft steam will be discharged.

However, limited by the separation effect, a part of engine oil will still enter the intake manifold in the exhaust gas, and then be recycled to participate in combustion. However, when the high-temperature exhaust gas meets the low-temperature intake manifold and the low-temperature throttle, it will combine with the dust in the air and condense on the back of the throttle to form sludge.
