摘要： A fuel injection system for internal combustion engines comprises a fuel injector that injects fuel into a combustion chamber, the combustion chamber being delimited by a cylinder wall in which a piston is guided, and a spark plug that protrudes into combustion chamber. The fuel injector produces a conical mixture cloud in the combustion chamber through at least one row of injection orifices arranged circumferentially on a valve body of the fuel injector. The valve body also provides a centrally arranged injection orifice that produces a central area of the mixture cloud directed towards the spark plug.

摘要： A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed in the top surface of a piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relatively small thickness. When the fuel injected in nearly the shape of a fan from the fuel injection valve is considered by being divided into a plurality of fuel segments in a radial direction, a side wall of the cavity has a first fuel deflection passage 82a and a second fuel deflection passage 82b for so deflecting at least two of the plurality of fuel segments as to pass near the spark plug. The side wall of the cavity is at least partly provided with a return portion 83 that protrudes toward the inside of the cavity. The first fuel deflection passage is not provided with the return portion 83 or is provided with the return portion having a short protrusion, and the second fuel deflection passage is provided with the return portion 83 having a long protrusion.

摘要： A pressure atomizer includes a silicon plate having a top surface and a bottom surface. A portion of the top surface defines a turbulent chamber. The turbulent chamber is peripherally bounded by the top surface of the plate. The turbulent chamber is recessed a predetermined depth relative to the top surface. The silicon plate further defines at least one flow orifice. Each flow orifice extends from the bottom surface of the silicon plate to intersect with and open into the turbulent chamber. Each flow orifice is in fluid communication with the turbulent chamber.

摘要： During operation with part load, a gasoline internal combustion engine is operated with a lean air/fuel mixture by auto-ignition. During operation with full load, spark-ignition is used to operate the engine. The internal combustion engine is operated in three auto-ignition combustion modes depending upon magnitude of a predetermined operating parameter. The operating parameter is indicative of the engine load or the engine speed. The three auto-ignition combustion modes are a gasoline reform auto-ignition combustion mode, an auto-ignition stratified charge combustion mode, and an auto-ignition homogeneous charge combustion mode. In the gasoline reform auto-ignition combustion mode that may be selected during operation with low part load, a first fuel injection during an exhaust gas retaining phase produces sufficient amount of active fuel radicals for promotion of auto-ignition of air/fuel mixture produced by a second fuel injection during the subsequent compression phase. In the auto-ignition stratified charge combustion mode that may be selected during operation with intermediate part load, a fuel injection during compression phase supports auto-ignition. In the auto-ignition homogeneous charge combustion mode that may be selected during operation with high part load, a fuel injection during intake phase supports auto-ignition.

摘要： A cylinder head arrangement for a direct injected internal combustion engine and particularly one having multiple valves. The cylinder head configuration is such that the injector can be positioned centrally in the combustion chamber and disposed below the overlying ports, which preferably are the inlet ports without significantly detracting from their flow area or without requiring sharp curvature or bends in their configuration that could restrict air flow.
