| Abstract: | In order to increase testing precision of engine oil consumption, the influence of return pressure of fuel injection pump on the testing precision was analyzed and some tests were carried out. The testing results indicated that the return pressure of fuel injection pump was the main reason of increasing testing errors. These errors were eliminated by using software and antivibration method, and its testing precision increased by 1 43% or so. |
