In-Cycle Closed-Loop Combustion Control with Pilot-Main Injections for Maximum Indicated Efficiency
An in-cycle closed-loop combustion controller is proposed in this paper. The controller uses a pilot-main injection scheme where the cycle-individual properties of the pilot combustion are estimated by in-cylinder pressure measurements, and used to predict their effect on the heat release shape of the main combustion. The prediction is used to obtain the optimal main SOI that gives the Maximum Rea
