Abstract: An intake and exhaust system for a dual mode HCCI engine, which provides superior intake temperature control and homogeneity for engine operation in SI and HCCI modes, as well as during transition between SI and HCCI modes and vice-versa. The system includes adjusted intake cam movement event lengths for intake valve operation at specified modes of operation. The system further includes at least one cam profile switching device operatively connected to intake and exhaust valves in an engine for controlling event length, maximum lift, and valve opening/closing timings for the intake and exhaust valves. The system yet further includes a bifurcated intake system and camless valve actuators for controlling intake valves for facilitating operation in SI or HCCI modes, as well as transition between SI and HCCI modes and vice-versa.

Abstract: An inlet air compressor for an internal combustion engine is provided which has one inlet and a plurality of outlets. Within the compressor are disposed a plurality of diffusers coupled to the plurality of outlets. The flow is divided among the plurality of outlets so that at conditions of low overall flow rate through the engine, which would, in a compressor according to the prior art, ordinarily surge, allow the flow to be substantially discontinued through one or more diffusers and continue at through the remaining diffusers. In this way, the diffusers with flow operate within an acceptable operating range and avoid a surging condition. The present invention is directed to engines having a wide range of flow rates. A couple of examples are gasoline engines and variable displacement engines.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An internal combustion engine is provided having a luminosity detector and an arrangement for adjusting the parameters of the engine in response to sensed combustion conditions within the combustion chamber based on particular gain independent parameters of the luminosity signal. The gain independent luminosity parameters can also be used to obtain uniform combustion conditions from cycle to cycle in a given combustion chamber and uniform combustion in the combustion chambers of multi chamber engine.
