Abstract

A combustion chamber for an internal combustion engine includes a closed end cylinder having an axis. A piston is reciprocable in the cylinder and includes a generally flat rim having an inner edge surrounding a recessed bowl into which the fuel is primarily injected, the bowl having a floor and a surrounding side formed by an arcuate surface connecting tangentially with the floor and extending to the rim inner edge. A spark plug has a centerline through the spark gap and is offset to one side of the cylinder axis with the spark gap extending into the combustion chamber toward the axis. A fuel injector is offset to an opposite side of the axis with the spray tip aimed to direct a generally conical fuel spray into the piston bowl with a portion of the fuel spray passing near the spark gap. Various dimensional characteristics are disclosed.
