本文介绍了一种测取气缸压力图的数字记录系统。该系统也可以用来测取发动机的其它瞬变参数。文中还介绍了在压缩上止点附近取样的方法和一种结构紧凑、分辨率较高的曲轴转角信号发生器。
This paper presents a digital recording system for measuring cylinder pressure maps. The system can also be used to measure other transient parameters of the engine. The paper also introduces a method of sampling near compression top dead center and a compact and high resolution crankshaft angle signal generator.
