| Abstract: | Aimed at analyzing the injection characteristics of high pressure common rail system from the both sides of theory and test,taking Bosch 2nd generation common rail system CRSN2 as the research object,with INCA 5.4 calibration software integrated on-line calibration experiments on injection characteristics are conducted.The test data shows that the influence of injection characteristics on engine dynamic performance is obvious,such as dynamic,fuel economy and emission.At the same time,the reason of the injection characteristics influenced on diesel engine performance is analyzed from the fuel injection and the combustion within cylinder in theory,therefore the test results are further validated. |
