摘要

Fuel injection profile variations play a critical role in advanced combustion mode control for diesel engines and also possess control authorities on engine in-cylinder conditions (ICCs). In order to systematically utilize the active fueling control, in conjunction with air-path control, for transient operations of advanced multimode combustion diesel engines, this paper presents a physics-based, control-oriented model that describes the inherent dynamics from fuel injection profile variations to the intake gas conditions. To show the effectiveness of the developed control-oriented model, comparisons were made with the simulation results from a high-fidelity GT-Power computational engine model as well as the experimental data acquired on a medium-duty diesel engine during transient operations.
