不少进口小型汽车的发动机行驶一定里程后,会出现冷起动后发动机发抖、怠速不稳、冷加速困难、容易熄火等现象,究其故障的原因主要有: (1)加速装置工作不良:加速泵工作不良,冷起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,化油器主控中应有一股很强的燃油喷出,如喷油少、喷油无力或不 Many imported small car engines travel a certain mileage, there will be cold start after the engine shudder, idle speed instability, cold acceleration difficulties, easy to stall and so on, the reasons for the failure are: (1) Accelerator poor work: Accelerate Poor pump work, less fuel injected during cold start-up, causing the engine to shudder as it accelerates. Check the air filter can be removed, each time the accelerator pedal, carburetor control should have a strong fuel injection, such as less fuel injection, fuel injection is weak or not
