This paper proposes the engine simulator in which the piston-crank mechanism is an actual system and gas flow from the intake to the exhaust strokes including the combustion stroke is the model. The term “actual” mentioned above does not mean the real product but just the physical scale model in this study. It allows us to analyze detailed phenomena difficult to recreate by simulations such as the elastic effect of the crank shaft and to combine an actual electric motor and a generator with the drivetrain starting from the crank shaft to develop a HEV simulator.
This paper is organized as follows: In the Section 2, the concept of the proposed engine simulator is described. In Section 3, the detail of the piston-crank system designed in this study is introduced. In Section 4, a cycle by cycle simulator, which is based on the model distributed by the joint committee of SICE and JSAE (Ohata 2012), is briefly explained. In Section 5, a dynamic characteristics compensation based on a disturbance observer is explained. This paper is summarized in the last section.
