【Abstract】 The structure and working of actuators and electronic control hardware of high pressure common rail FIS is described in brief. Basing on the characteristic of a vehicle diesel,we had designed a large number of control strategies to meet the exhaust emission regulation and users’ demand.The system has realized the independent control of injection quantity,injection timing,injection rate and injection pressure. The test shows the system is feasible.更多还原
