  • Combustion chamber structure of in-cylinder fuel injection type engine
    Patent number: 6708667
    Abstract: A combustion chamber arrangement for a direct fuel injected internal combustion engine wherein the combustion chamber is formed in part by a recess in the piston head. Fuel is injected into the combustion chamber so as to be introduced on one side of the recess with a spark plug being positioned so that its gap lies diametrically opposite the fuel injector. An arrangement is provided for introducing a swirl to the flow of fuel and the combustion chamber recess is canted so that its lower surface is deeper where the fuel first enters then on the other side so as to improve flame propagation and complete combustion while maintaining a high compression ratio.
