Internal combustion heat engine, control system, method for dimensioning the engine, and automobile with said engine

Abstract

The invention relates to an internal combustion heat engine, with at least one combustion chamber for intake gases comprising a mixture consisting of a fuel such as petrol and an oxidiser such as air, connected to an intake circuit (A) for the intake of said intake gases into the chamber and an exhaust circuit (B) for the exhaust of the burnt gases outside the chamber, an exhaust gas recirculation circuit (C, D) connecting the exhaust circuit to the intake circuit, and a control system for the exhaust gas recirculation. The control system is arranged so that the exhaust gas recirculation is implemented for at least one operation point defined by an engine speed and a torque output by the engine, for which the output torque is higher than 50% of the maximum engine torque. The invention can be used for operating the engine with optimal stoichiometric mixture and ignition advance without the occurrence of rattling.
