ABSTRACT:
A combustion chamber of a positive-displacement spark-ignited internal combustion engine is divided into a main combustion chamber and a pre-combustion chamber having proximal and distal ends. The proximal end is connected to the main combustion chamber and a spark-ignition device is located at the distal end. Within the pre-combustion chamber, a plurality of passageways extend between its proximal and distal ends so that a flame front ignited by the ignition device at the distal end of the pre-combustion chamber propagates along the plurality of passageways as separate flame fronts toward the proximal end of the pre-combustion chamber. A displacer separates a premixing chamber from the pre-combustion and main combustion chambers. The displacer is relatively moveable for transferring the charge of fuel and air from the premixing chamber into the pre-combustion main combustion chambers.
