ABSTRACT:
For charging the combustion chambers (10) provided with an inlet (14) and an outlet (16) valve of an IC engine of the piston type there is a charger (20) producing a continuous pressure and pumping into a storage space (28). In a way dependent on the ignition frequency of the associated combustion chambers (10) an air control valve (34) is opened and closed which is arranged between the storage space (28) and an inlet duct (36) leading to the inlet valve (14) of these combustion chambers (10). The phase relationship of the valve (34) to the inlet valve (14) may be changed in a way dependent on the required manner of operation of the engine between a position concentrating the air supply from the storage space (28) on the start of inlet and a position concentrating the supply on the end of inlet to such combustion chambers (10), each duct (40) supplying each combustion with non-compressed charge being shut off on the side of the combustion chamber to be supplied.
