In order to meet the increasingly strict emission regulations, more complex control systems are used in the engine, which increases the calibration workload by several times. Virtual test bed is a method to greatly reduce the calibration cycle, workload and cost by replacing the real engine and vehicle for the hardware in the loop virtual calibration research. Virtual calibration process mainly includes experiment design, virtual experiment, model construction, data optimization, MAP generation and calibration result test. This paper mainly describes the establishment method of the simulation model of diesel engine of China 6 applied to virtual calibration based on the AVL CRUISE TM M and MoBEO TM . The differences between the test results and the simulation results under the steady-state and transient conditions of the model were compared. The results of stationary mode and cold WHTC show that the model is of good quality and can be used in the research of virtual calibration development.
