    摘要: A three-valve cylinder head system for a direct-injected spark-ignited (DISI) internal combustion engine. Two inlet ports are positioned in opposite quadrants of the cylinder head, with the fuel injector directing fuel spray into a third quadrant and the exhaust port being positioned in the fourth quadrant. A helicoid intake port and an axially directed intake port generate a swirl-type air flow in the piston cylinder without the aid of flow activation devices. The spark plug is positioned centrally adjacent the longitudinal axis of the cylinder bore. The piston has a bowl in its upper surface with an enlarged downstream area and a harbor area adjacent and past the spark plug which allow the swirl-type air flow to mix with the fuel spray and provide an appropriate fuel air mixture at the spark plug.

    摘要: Swirl motion of gases in a combustion chamber of an engine is affected by changing the timing of opening and closing one of two intake and/or exhaust valves. By retarding the opening of one intake valve relative to a second intake valve, swirl motion can be enhanced for the intake gases in the engine cylinder. Similarly, by retarding the opening of one of two exhaust valves, swirl motion can be induced for the residual gases. The system may include electric or hydraulic actuators or mechanically controlled valves. A variable valve lift system can also be used to control swirl motion in a combustion chamber.

    摘要: A stratified-charge combustion system design for direct-injection spark-ignited engines with the piston bowl in the exhaust-valve side. The air flow from the inlet valve provides a normal tumble in cylinder air flow. The fuel injector is positioned on the intake-valve side of the combustion cylinder and forms a charge stratification in the combustion chamber. With the piston bowl on the exhaust-valve side, the distance for spray penetration of the fuel from the injector is extended. The rate of fuel spray penetration in the combustion chamber is reduced by counter air flow against the fuel spray. The air-fuel mixture is moved upwardly to the area of the spark plug by the tumble air flow for ignition. The invention provides less piston bowl wall wetting which results in less soot formation and less emissions of undesirable hydrocarbons.

    摘要: A stratified charge is formed in a direct injection engine by injecting fuel at a predetermined velocity, a predetermined droplet size, and forming the injected fuel with a hollow cone having a predetermined initial cone angle. The injected fuel thereby shallowly penetrates the combustion chamber so as to float therein to reduce wall-wetting and subsequent soot formation. A substantially flat top piston forms the injected fuel into a ball-shaped kernel during a compression stroke of the engine. The ball-shaped kernel remains substantially unmixed with the inducted air, thereby producing the stratified charge. The continued motion of the piston causes the ball-shaped kernel to move toward the spark plug for ignition.
