Abstract
An improved combustion chamber configuration for a direct injected internal combustion engine. The cylinder head recess and piston head are configured so as to provide a small clearance volume and accordingly high compression ratios while the shape of the piston head and the arrangement of the cylinder head recess permits a portion of the injected fuel to be directed toward the exhaust valves to cool them and reduce smoke and increase fuel efficiency.
