摘要： A piston for a lean-burn gasoline engine comprising a cylinder, an air inlet and an exhaust outlet, wherein the air inlet and the exhaust outlet are arranged about a longitudinal axis of the cylinder. The piston comprises a central axis which is aligned with the longitudinal axis of the cylinder. The working surface (79) of the piston (454) comprises a central dished portion and an outer sloped portion surrounded by an outer sloped portion. A first pair of valve pockets (444a, 444b) are located in the outer sloped portion on a first side of the dished portion, and a second pair of valve pockets (445a, 445b) located in the outer sloped portion on the second side of the dished portion. The dished portion comprises a ramp protuberance located between the first pair of valve pockets. The dished portion is configured to promote tumble of air flow into the cylinder from the air inlet, in use during an intake stroke of the piston.

摘要： This liquid injection nozzle atomizes and sprays liquid, while reducing loss of kinetic energy, thereby promoting mixing between the liquid and a gas and thus promoting the reaction between the liquid and the gas. In the liquid injection nozzle, a plurality of distal end tips each having an injection hole are provided on a distal end portion of a nozzle body. Each distal end tip has a conical swirling flow chamber. A communication thin hole is formed in the distal end portion. The communication thin hole extends from a hollow chamber to the conical swirling flow chamber of the distal end tip. When the valve needle is lifted, liquid flows through the communication thin hole into the swirling flow chamber in a tangential direction and generates a vortex flow, and the vortex flow is sprayed from the injection hole.

摘要： A method for operating an internal combustion engine of a motor vehicle having a cylinder, the combustion chamber of which is delimited in the radial direction by a cylinder wall and in the axial direction by a piston and by a combustion chamber roof. The piston has an annularly peripheral piston stage which is arranged axially recessed in the piston compared with an annularly peripheral piston crown and which merges via an annularly jet splitter contour into a piston hollow arranged axially recessed in the piston in relation to the piston stage. An injector is allocated to the cylinder and via the injector several injection jets are simultaneously injected directly into the combustion chamber in a star shape for a combustion process.

摘要： A fuel injection control device for an engine is provided. A swirl generator generates a swirl flow inside a combustion chamber. A fuel injector with multiple nozzle holes injects fuel into the combustion chamber, and forms a lean mixture gas inside the combustion chamber. An spark plug ignites the lean mixture gas to cause the mixture gas to start combustion accompanied by flame propagation, and then combust by self-ignition. A first atomized fuel spray injected from a first nozzle hole and a second atomized fuel spray injected from a second nozzle hole separate from each other by the swirl flow. The fuel injector sequentially performs first and second injections in an intake stroke. A ratio of an injection amount of the second injection to the entire amount of fuel required per cycle is increased as an engine load increases.

摘要： A fuel injection control device for an engine is provided. A swirl generator generates a swirl flow inside a combustion chamber. A fuel injector with multiple nozzle holes injects fuel into the combustion chamber, and forms a lean mixture gas inside the combustion chamber. A spark plug ignites the lean mixture gas to cause a portion of the mixture gas to start combustion accompanied by flame propagation, and then combusts by self-ignition. The fuel injector has first and second nozzle holes, and a first atomized fuel spray injected from the first nozzle hole and a second atomized fuel spray injected from the second nozzle hole separate from each other by the swirl flow. The fuel injector performs the fuel injection in an intake stroke, and retards a start timing of the injection when an engine load is high compared to that when the load is low.
