ABSTRACT:
The present invention relates to a method for feeding the combustion chamber of a two-stroke engine, according to which the constituents of the combustible mixture are admitted into the combustion chamber via two intake devices at the bottom of the cylinder. Air without fuel is admitted through two ports, symmetrically disposed with respect to the vertical plane containing the axis of the exhaust port, directed towards the wall opposite the exhaust; the petrol-and-air mixture is admitted through at least one port remotest from the exhaust so that the stream of carburetted air is directed towards the cylinder head, the carburetted mixture thus being maintained towards the wall opposite the exhaust by the two streams of air without fuel until the ports are closed. The invention finds particular application in the field of automobile construction.
