Mean Value Engine Modeling and Validation for a 4-stroke, Single Cylinder Gasoline Engine

Wen-Po Chaing, Liangtao Zhu and Ravindra Patankar

Abstract:
Mean Value Engine Model has been widely used in model based engine control development. In this paper, an engine model is presented for a 4-stroke single cylinder gasoline engine with respect of electrical throttle control development. The two-state nonlinear model mainly consists of two subsystems-the intake manifold and the crankshaft. The former subsystem represents dynamics of the intake manifold air mass flow, as well as the amount of fuel entered into the cylinder. The latter subsystem mainly accounts the dynamics of the crankshaft loading. Some empirical parameters in the model, such as the volumetric efficiency, are identified by using measured operating data from the engine. The steady state performance of the nonlinear engine model is then validated by experimental data of the engine. The model output shows relatively good agreement with the experiment measurements. It verifies that the MVEM model is appropriate for this application of automatic electronic throttle control development for maintaining a fixed speed.
