| Abstract: | Design of injection control strategy is an important part in the development of high pressure common rail diesel engine. Based on ECD-U2 common rail system and ECU developed independently, this paper analyzed control requirement in various conditions of diesel engine. And then injection control software was designed and realized according to detailed control strategy, which enables steady rail pressure, precise fuel quantity and injection timing, as well as the performance of rapid starting and stable running. Finally, the test results verify the control precision, feasibility and reliability, and anticipated control effect was achieved. |
