Two stroke engine without sump-pump

The two-stroke internal combustion engine uses a compressor (2) which feeds air via channels, and through ports (4) which are uncovered by the movement of the piston (7). A filter (1) purifies the air drawn in by the compressor, and the air is cooled by a heat exchanger placed between the compressor and the cylinder. The two-stroke internal combustion engine uses a compressor (2) in place of the crankcase pump and action of the cylinder to provide fresh gas in the cylinder. The compressor feeds into the channels and vanes serving to orientate the gas flow (5) which is directed into the cylinder through ports (4) which are uncovered by the movement of the piston (7) on either side of its dead center position. A filter (1) purifies the air drawn in by the compressor, and the air is cooled by a heat exchanger placed between the compressor and the cylinder. The cylinder includes a mechanism (11) allowing variation in the section and the duration of opening of the exhaust port (8). Fuel is injected by one or more high pressure injectors (9), with electrical or electronic control, prior to ignition by a spark plug (10).
