Abstract
A process controls the combustion of an internal combustion engine with controlled ignition and liquid fuel direct injection. The engine includes at least one cylinder with a combustion chamber, at least one intake, at least one exhaust and at least one direct injector for liquid fuel in order to obtain a fuel/air mixture in the combustion chamber.The process includes determining the operational zone of the engine in which particulates are emitted during combustion of the fuel/air mixture and, for operation of the engine in this determined zone, introducing into the combustion chamber another fuel/air mixture resulting from indirect injection of a gaseous fuel.
