不少进口轿车在行驶一定里程后,会出现冷启动后发动机发抖,怠速不稳、冷加速困难、容易熄火等现象,鉴于进口轿车的结构特点,其故障原因主要有以下几方面: 1.加速装置工作不良 加速泵工作不良,冷启动加速时喷入汽油量少,导致加速时发动机发抖。检查时可将空气滤清器取下,每踏一次加速踏板,化油器主腔中应有一股很强的燃油喷出,如喷油少、喷油无力或不喷 Many imported cars in a certain mileage, there will be a cold start after the engine shivering, idle instability, cold acceleration difficulties, easy to stall and so on, in view of the structural characteristics of imported cars, the main causes of failure are the following: 1. Acceleration Improper installation of the device accelerates the pump to work badly, and when the cold start accelerates, the amount of gasoline injected is small, causing the engine to shudder when accelerating. Check the air filter can be removed, each time the accelerator pedal, carburetor main cavity should have a strong fuel injection, such as less fuel injection, fuel injection is weak or not
