摘　　要：介绍了一种防止发动机曲轴箱通风管路在极寒条件下结冰的装置和方法,装置包括发动机气门室罩盖、进气软管及全负荷呼吸管、发热电阻丝、环境温度传感器、线束及电控单元ECU。当环境温度传感器将测定的环境温度转化为电信号传输给电控单元ECU,ECU根据设定程序接通发热电阻丝,使曲轴箱通风管加热器开始工作。该方法解决了发动机曲轴箱通风系统在极寒地区结冰问题,保证了车辆在寒区使用的可靠性。A new idea is introduced by preventing engine breath system freezing in extremely cold condition. It includes cover, intake pipe and full load breathing pipe, heat resistance, surround ings temperature sensor, wiring harness and ECU. When surrounding temperature sensor transfer the temperature into current signal to transmit to ECU, heat resistance is turned on according to the proce dure to make crankcase ventilation tube heater start working. This method can prevent engine crank case ventilation tube freezing and guarantee the durability of the car in cold condition.
