Abstract
A spark plug ignited internal combustion engine in which each cylinder is provided with a turbulence chamber in which the exhaust valve is located. The cylinder head and the top of the piston cooperate during the compression stroke to define a guide channel through which combustible gases are introduced in off center manner to the turbulence chamber where a substantially single vortex flow is created. The spark plug is preferably located so that the sparking electrodes are in the turbulence chamber or nearby in the guide channel and are in close proximity to the top of the piston at TDC. In one embodiment, the inlet valve is located in a depression of the cylinder head so configured that, during the initial valve opening, the inflowing gases are constrained to flow toward the center of the combustion chamber, thereby preventing contact with the cylinder walls.
