用压磁法测量柴油机的喷油规律是国外七十年代发展起来的一种新颖的测试方法,国内也刚刚起步摸索。本文介绍了压磁法喷油规律测试装置的结构和工作原理,首台装置试运转中发生过的问题和解决途径,对压磁法喷油规律测量方法的精度作了初步探讨,文章最后列举了所研制的测量方法的特点,它们是区别于国外报道的独到之处。
Measuring the law of diesel injection by compression method is a novel test method developed abroad in the seventies and has just started to explore in China. This article introduces the structure and working principle of the test device of the law of pressure and magnetic fuel injection, the problems that occurred during the test run of the first device and the ways to solve the problem. The precision of the method of measuring the law of fuel injection by pressure and magnetic method is preliminarily discussed. Finally, The characteristics of the measurement methods developed, they are different from the uniqueness of foreign reports.
