Dynamic Simulation of a Turbocharged/Intercooled Diesel Engine with Rack-Actuated Electronic Fuel Control System 890394

A comprehensive simulation has been developed which describes the dynamic response of a turbocharged, six cylinder diesel engine fueled by an in-line pump-line-nozzle system with electronic control of a solenoid-actuated rack. The mathematical models of components, governing strategies and control algorithms are general, having been developed to address issues related to the dynamic response and control of both components and the overall system in a variety of engine propulsion and power system applications. The physical principles and salient characteristics of the independent subsystem models are reviewed. Results of the overall system simulation, featuring interactions between the engine, microprocessor-based governor, and solenoid-actuated rack are presented to demonstrate the utility of dynamic simulation as a basis for evaluating system performance and exploring control strategies for optimum response.
