一、基础检验 基础检验的目的是检验自动变速器是否还具备工作的能力。检验的前提是发动机工作正常,底盘性能良好,制动系统正常。 1.发动机怠速检验 手柄处于N档,怠速值应正常。 ①怠速过低:档位转换时,轻者引起车身振动,重者发动机熄火。 ②怠速过高:在D档、R档,不踩油门即“爬行”。换档时发生冲击和振动。怠速过高可能是怠速失调或
First, the basic test The purpose of the basic test is to test whether the automatic transmission also has the ability to work. The premise of the test is the engine is working properly, the chassis performance is good, the brake system is normal. 1. Engine idle speed test handle in N range, idle speed should be normal. ① idle speed is too low: gear conversion, light caused by body vibration, heavy engine flameout. ② idle speed is too high: In the D file, R file, do not step on the gas that is “crawling.” Shock and vibration occur while shifting gears. High idle speed may be idling or idling
