ABSTRACT:
This invention relates to a two-stroke, spark ignition, internal combustion engine, with two, three, four or six cylinders. Fuel injection is provided by means of combustion gases and no fuel pump is employed. The working spaces of the engine cylinders are interconnected by means of ducts in such a manner that during the working stroke a small amount of high pressure combustion gases enters the working space. After the duct port is uncovered by the piston the combustion gases are carried over on their way by a predetermined amount of fuel, thereby effecting the injection.
