涡流室式柴油机的涡流室和主燃烧室之间的压力差非常小,以至于很难测量出来,因此其放热过程和温度曲线至今尚不能确定。为了确定二个燃烧室的燃气温度,作者研究出一种新的方法。按照示功图和装在连接通道里的电离探测器发出的讯号,可先得到二个燃烧室里的放热过程,然后用二个微分方程式即可算出燃气温度的变化曲线。在日本的三江大学进行了不同喷油量的试验。 The pressure difference between the vortex chamber and the main combustion chamber of a vortex chamber diesel engine is so small that it is difficult to measure and therefore its exothermic process and temperature profile are not yet known. In order to determine the gas temperature in the two combustion chambers, the authors developed a new method. According to the dynamometer and the signal from the ionization detector installed in the connecting channel, the exothermic process in the two combustion chambers can be obtained first and then the curve of the gas temperature can be calculated by using two differential equations. Sanjiang University in Japan conducted a different fuel injection test.
