ABSTRACT:
A combustion chamber structure for an internal combustion engine, which combustion chamber structure includes a main combustion chamber and a separate auxiliary combustion chamber. The main combustion chamber is supplied solely with air by a conventional intake valve. A passage interconnects the main and auxiliary combustion chambers for permitting air to flow into the auxiliary combustion chamber during the compression stroke of the piston. The auxiliary combustion chamber has a fuel-injection nozzle and a spark ignition plug associated therewith. An obstacle, such as a spherical or cylindrical member, is positioned within but spaced from the sidewall of the auxiliary combustion chamber, whereby a circular flow pattern is created within the auxiliary combustion chamber which improves the fuel atomization and the uniformity of the fuel-air mixture. The spark plug is positioned adjacent the passage which interconnects the chambers so as to result in proper stratified combustion within the main chamber, while also minimizing noise.
