柴油机喷油系统的发展提出了一系列为普通实验室器械诸如:示波器、电子传感器或频闪仪等所不能解决的问题,因而有关这方面的特殊测试装置必须相应发展。下方即介绍Sulzer公司所建立的这种试验装置。这些装置正是为压力波测量、汽囊现象、喷油泵输出阀升程或喷油嘴温度测量以及燃烧重油时滞燃期的测试中所必需的。 The development of diesel engine fuel injection system presents a series of problems that can not be solved by common laboratory instruments such as oscilloscopes, electronic sensors or stroboscopes. Therefore, special test equipment in this area must be developed accordingly. Below is a description of the test rig set up by Sulzer. These devices are necessary for pressure wave measurements, airbag phenomena, injection pump output valve lift or injector temperature measurement, and testing of the fuel burn-up time.
