为了判断柴油机混合气的形成及燃烧的情况,除了要了解燃烧过程之外,还要对喷射过程进行研究。这在运转的柴油机上就要对一般所测的高压油管压力波及针阀升程曲线进行计算。下面将叙述计算程序,并假设喷射过程只由所测的高压油管压力波决定。与目前所采用的普通方法相反,由于不对针阀升程进行测量,所以减小了试验费用,且由于对喷嘴油腔的实际压力进行计算,所以提高了精确度。下面将给出几个结果,并与目前所采用的方法相比较。
In order to determine the formation of diesel mixture and combustion, in addition to understanding the combustion process, but also on the injection process. This is the operation of the diesel engine will be measured on the general pressure of the high-pressure pipe valve stroke curve stroke calculation. The calculation procedure will be described below, and it is assumed that the injection process is only determined by the measured pressure of the high-pressure tubing. In contrast to the conventional methods currently used, the test costs are reduced since the needle valve lift is not measured and the accuracy is increased due to the calculation of the actual pressure in the nozzle oil chamber. A few results will be given below and compared with the methods currently used.
