Abstract
An engine combustion chamber includes a cylinder head, a cylinder wall and a piston. The piston has a bowl volume formed therein. A fuel injector is disposed adjacent one edge of the bowl and an ignition source is within a predetermined distance of another, substantially opposite, edge of the bowl. The bowl has a transporting surface which directs a fuel-air charge from the bowl volume toward the ignition source. The piston, bowl and cylinder head cooperate through a plurality of design features to provide an efficient combustion chamber.
