The Application of Modern Control Theory to a Turbocharged Diesel Engine Powerplant

A brief review of the intrinsic features of diesel engine performance and control is given. The introduction of electronic control to fuel systems is described. It is shown that engine dynamic performance (in the form of transfer functions) can be both calculated and measured. An example is given of multi-variable control techniques applied to a turbocharged diesel engine with variable geometry turbocharger. It is shown that there are significant benefits in terms of smoke emissions from such a system, and that the synergy of more controllable engine systems together with modern control techniques enable diesel engines to reduce emissions.
