Physical Model for Investigation of Diesel Engine Cranking by Belt-driven Integrated Starter Generator

Abstract

A new physical model to simulate the cranking behavior of diesel engines with a belt driven integrated starter generator (BISG) has been created. The model consists of individual sub models for the physical system components phenomena active during engine cranking. A rig for cranking testing has been used to acquire relevant cranking data. The model has been calibrated and validated with measurement data from the rig for a diesel engine in the 2 litre range.
