Model Based Torque Control and Estimation for Common Rail Diesel Engine

A rapid control prototyping based on torque control algorithm using V-cycle mode for common rail diesel engine was developed, and a torque prediction model was present which including a feed-forward mean value engine model and a feedback correction of error caused by the feed forward model. Finally, experiments were carried out on test bench to verify the control feasibility and reliability of the strategies and optimize the emissions, Experimental results showed that the anticipated control effects were achieved and the engine reached the EURO-III exhaust emission standard.
