Summary:

This paper describes a dynamic simulation model of a turbocharged diesel powertrain equipped with the Navistar T444E V8 engine. The T444E engine is the first diesel to utilize dynamic injection pressure control. Emphasis of this paper will be on powertrain dynamics pertinent to electronic control system design and development. Applications of the integrated system model include control strategy design and development of idle speed regulation, cruise and power take off control, driveline surge compensation, engine starting, injection timing and pressure control, and exhaust pressure control.The reported powertrain model features a hybrid multi-rate sampled data model for the diesel engine. Actual fuel injection is event-based with reference to crank-angle. Control algorithms are executed at fixed rates independent of injection events. Analyses of idle stability, engine-driveline dynamic characteristics, and multi-loop interaction are presented. Comparison of model prediction and field measurements are also made
