摘要：

Engine mathematical model can be used to simulate vehicle dynamic performance and fuel economy for vehicle design. Simulation of vehicle dynamic performance and fuel economy is based on mathematical model of engine. Least square method and multiple regression analysis were used to fit curve of external characteristics and universal characteristics when the test data of external characteristics and universal characteristics of engine are known. Torque and fuel consumption of engine can be calculated under the different operating conditions by the equation. Grid quantization method was used to simulate the characteristic when the test data of external characteristics and mapping characteristics are unknown and only the engine characteristics curve is known. © 2012 ACADEMY PUBLISHER.
