ABSTRACT:
An internal combustion engine is designed to improve burning of the fuel therefor for reducing the harmful emissions in the exhaust gases thereof. An auxiliary combustion chamber is provided in the cylinder head being arranged to open toward the center of the cylinder through an orifice. A lean mixture fuel is introduced into a main combustion chamber formed by the cylinder walls, the cylinder head and the forward face of a piston reciprocable therein through a suction port curved for causing the lean mixture to swirl in one direction about the outer part of the main combustion chamber, and a rich mixture is introduced just in advance of a suction valve in said suction port which opens and closes communication between the suction port and the main combustion chamber upon actuation in a manner to swirl in a direction opposite to the lean mixture and near the center of the main combustion chamber. In compression, the rich mixture is thus drawn into the auxiliary combustion chamber where a spark plug ignites the same and fires the lean mixture in the main chamber by a flame jet of combustion passing through the orifice.
