Role of the Crank-Slider Structural Deformations in the Prediction of the Instantaneous Engine Friction Torque
Abstract
The focus of the current study is to assess the effects of structural deformations of the crankshaft/connecting-rod/piston mechanism on the computation of the instantaneous engine friction torque. This study has to be performed in a fully controlled environment in order to isolate the effects of structural deformations from those of measurement errors or noise interference. Therefore, a detailed model, accounting for the rigid and flexible motions of the crank-slider mechanism and including Rezeka and Henein’s (1984) engine component friction formulations, is considered in this study. The model is used as a test bed to generate the engine friction torque, Tfa, and to predict the rigid and flexible motions of the system in response to the cylinder gas pressure.
