摘要: A previously presented robust and fast diagnostic NOx model was modified into a predictive model. This done by using simple yet physically based models for fuel injection, ignition delay, premixed heat release rate diffusion combustion rate. The can be used both traditional high-temperature high-EGR, low-temperature combustion. It possible to maintain high accuracy calculation speed of the itself. root mean square relative error is 16% around one second on PC. Combustion characteristics such as CA50 general shape are well predicted aimed at real-time optimization in vehicle road. (Less)
