Abstract
Based on diesel engine equipped with common rail, the multi-injection strategies common rail diesel engine test bed is established with NI test system. In this test bed, the influences of optimized multi-injection strategies to diesel engine performances are studied. The test results show that by using multi-injection strategies, the diesel engine exhaust temperature can reduce 50°C, and noises can reduce 15dB, and emission improve obviously.
