汽车对环境的污染不仅仅来自于尾气排放,燃油蒸发、曲轴箱窜气及废旧蓄电池的不当处理等都是造成环境污染的重要来源。本文仅以捷龙乘用车燃油蒸发污染控制系统为例,简要介绍其组成和工作原理,以及维护过程中应注意的问题。捷龙乘用车燃油蒸发污染控制系统的作用是将燃油蒸气通过相关管道临时存放在活性炭罐内,当发动机工作时,发动机电控单元(ECU)根据发动机的运行工况,控制相关电磁阀,使临时存放在活性炭罐内的燃油蒸气被吸入发动机
Car pollution of the environment not only from exhaust emissions, fuel evaporation, crankcase blow-by gas and improper disposal of waste batteries are all important sources of environmental pollution. This article only to the fuel tank pollution control system of the Jetta passenger car, for example, briefly introduces the composition and working principle, and maintenance should pay attention to the problem. The function of the fuel vaporization pollution control system of the Jetta passenger car is to temporarily store the fuel vapor in the activated carbon canister through the relevant pipeline. When the engine is working, the ECU of the engine controls the relevant solenoid valve according to the operating condition of the engine, The fuel vapor temporarily stored in the canister is drawn into the engine
