This paper is a study into the possibility of using new control strategies in a standard car. The air system of a diesel engine equipped with a variable geometry turbine and an EGR system (EGR valve and throttle) is considered. New strategies, like GPC or H∞ permit an improvement of the control of both the fresh air flow and the intake manifold pressure. These strategies are not used today in standard car due to the mismatch of both the instrumentation of the ECU’s calculation power. The cost of proposed technology to meet the next emission norm are presented. Some low cost solutions are presented to permit an improvement of the engine control.
