Closed loop control for common rail diesel engines based on rate of heat release

Abstract

In the last years, the guideline for injection control systems of diesel engines is the realization of a micro-controller, which is able in real-time to find, through an optimization procedure oriented to decrease polluting gases emitted by the engines and the engine fuel consumptions, the "optimal" injection strategy related to driver load demand. The "optimal" injection strategy is associated with the optimal tradeoff among the following conflicting objectives: maximize torque, minimize fuel consumptions, reduce noise and polluting emissions (NOx and soot). © 2006 Springer.
