Abstract

The engine comprises a cylinder (1), a housing (3) connecting with one of the ends of the cylinder (1), at least one transfer pipe (10) joining the housing (3) to the cylinder (1), a fuel injector (15) fed with air under pressure by a capacitor (18) connected to the housing (3) and an exhaust pipe (8). A means (22) of restricting the passage of the gases is arranged in the transfer pipe. The opening and closing of this means is controlled and regulated as a function of at least one operating parameter of the engine. This arrangement allows the quality of fuel injection to be improved. <IMAGE>
