piston group meaning in Chinese

活塞组

This paper deals with synchronous measure technology of the cylinder pressure with the engine cold start by adoping micro - chip aduc812 , and it discuss the analysis of breakdown of engine cold start with the mixture of technology of information . through the analysis of the parameters of cylinder pressure of the engine cold start , turning speed and starting electricity , and according to the measure data and witness , a theory is to be inferred , and with the help of breakdown - checking systems , the engine piston groups and the breakdown of starting system can be judged . at last , the . remote measure technology of cylinder pressure ' s parameters
本文采用微处理器芯片aduc812研究发动机冷起动气缸压力的同步测试技术，讨论了基于信息融合技术的发动机冷起动故障诊断方法。通过对发动机冷起动气缸压力、转速、起动电流等参数的测试，根据测试数据和证据推理理论，借助故障专家系统，判定发动机气缸活塞组以及起动系的故障。最后研究了气缸压力等参数的遥测技术。
