Realization of the Simulation Platform of Turbocharged Diesel Engine with EGR Loop Under Transient Conditions
Currently combustion and emission performance of diesel engine under transient conditions has become the researching focus. Its full of research challenges because of highly variability of engine operations and complexity of chemical reactions. A simulation platform of turbocharged diesel engine with EGR (exhaust gas recirculation) loop under transient conditions, based on the software coupling technique of GT-power and Matlab/Simulink, has been established. It simulated the EGR position step change transient operations and constant speed variable torque (CSVT) transient operation. Compared with the experimental results, it predicts the engine dynamics performance accurately. Based on this, the performance influences in three different kinds of fuel injection mass control strategies to the diesel engine under CSVT transient operation with EGR loop were discussed. It is shown that this simulation platform provides a new research method to improve transient diesel performance and explore control strategies of turbocharged diesel engine under transient conditions.
