曲轴箱窜气量检测仪的研制

Measurement instrument for the blow-by parameters of engine crankcases

介绍了车用压差式气体流量传感器的结构设计和电测电路 ,指出了传感器的使用范围 ,由实验测出了特性曲线 .该仪器可检测车用发动机曲轴箱窜气量 ,适用于发动机不解体故障诊断 .

A kind of vehicle-use pressure-difference gas-flow sensor and the electrical measurement circuit are introduced. The usage and the characteristic curve of the sensor are pointed out. It can be used to measure the blow-by parameters of engine crankcases accurately, and break down the diagnosis for the engine disassembled.
