N2 - Torque-based engine control system has been developed for complexity of powertrain control. Compared with open-loop torque control, close-loop control can improve control performance radically and reduce calibration workload greatly. For turbocharged diesel engine, dynamic torque generation model of Fuel Delivery-Mean Indicated Torque should be provided. The relationship between fuel delivery and mean indicated torque is nonlinear. In different operating points, engine demonstrates different dynamic torque output characteristic. Through piecewise linearization and identification, dynamic torque generation model has been obtained in different operating points. Based on this model, close-loop torque and engine speed control algorithm can be investigated further.
