How to adjust Excelle's low idle speed?

How to adjust Excelle's low idle speed? How to adjust Excelle's low idle speed? Excelle's low idle speed can be found in the throttle idle motor, which is specially used to adjust idle speed. Left and right adjustment can change the idle speed of Excelle. The following is an introduction about idle speed: 1. Detection method: (1) Low battery voltage: Test the battery voltage with a three-meter voltmeter. If it is lower than 10V, it is recommended to replace it. If it is around 1 1V, it is barely used; Be prepared to be replaced. 12V or more is ok. (2) check whether it is caused by carbon deposition; If driving around 20000KM, check and clean the throttle. 2. Impact of idle speed on gasoline engines: (1) Economy: According to statistics, about 30% of the fuel of urban motor vehicles is consumed at idle speed. Therefore, it is very important to reduce idle fuel consumption, which is also the requirement of idle speed control. (2) Emission: When the gasoline engine is idling, there is a large amount of residual exhaust gas in the cylinder. In order to ensure the stability of combustion, it is necessary to add rich mixture, so the combustion is incomplete and a large number of harmful emissions of CO and HC are produced. @20 19
