    摘要: In an internal combustion engine with spark ignition and one or more reciprocating pistons, with an ignition device and at least one fuel delivery device for each cylinder, and with a combustion chamber bounded by a roof-shaped top face, the surface of the piston top is provided with an unsymmetrical, arched flow guiding rib assisting the swirl movement of the cylinder charge. The flow guiding rib is configured as an integral part of the piston top surface, which largely conforms to the roof-shaped top of the combustion chamber, and includes an essentially centrically positioned combustion chamber recess with an entrance area in close proximity of the fuel delivery device.

    摘要: A four-stroke internal combustion engine with a gabled combustion chamber d at least two intake valves and at least two intake conduits per cylinder, of which a first intake conduit is embodied as unthrottled and a second intake conduit has a throttle device. To attain a stable radial mixture layering, it is provided that the fuel injection valve is disposed in the second intake conduit, and the throttle device in the closed state produces a defined minimum flow rate of between about 5% and about 20%, preferably about 10%, of the maximum flow rate, and that viewed in the direction of the crankshaft axis the center line of the first intake conduit in the intake valve region has a greater radius of curvature than does the center line of the second intake conduit.

    摘要: In an internal combustion engine with spark ignition and one or more reciprocating pistons, with an ignition device positioned in a roof-shaped top face of the combustion chamber and at least one fuel delivery device for each cylinder for direct fuel delivery essentially in the direction of the ignition device, and with at least one intake port configured so as to generate a swirl movement, the piston exhibits an asymmetrically shaped piston recess whose walls are configured as arcuate flow guiding faces assisting the swirl movement of the cylinder charge. To obtain reliable ignition of the directly introduced fuel on the one hand and maximum liberty in designing the engine on the other hand, the proposal is put forward that the piston recess between opposite walls should essentially constitute an open channel of meander-shaped or S-shaped configuration in plan view, at least one end of the channel forming an inlet area into the recess, which starts at the piston rim.

    摘要: A device for introducing fuel into the combustion chamber of an internal combustion engine, includes an injection valve for withdrawing compressed gas from the cylinder and injecting the gas together with the fuel into the cylinder, a mixing chamber in the front part of the valve for the purpose of gas storage and into which mixing chamber fuel is introduced via one or more flow passages opening into the mixing chamber, the injection valve being provided with a lifting valve for control of the gas exchange between the combustion chamber and the mixing chamber in the front part of the valve, and an orifice where the flow passage opens into the mixing chamber located in the area of the seat of the lifting valve. To improve mixture preparation in the mixing chamber the fuel flow passage is constituted, at least in part, by a longitudinal bore in the valve stem of the lifting valve, the fuel being introduced into the valve stem in an area of the lifting valve distant from the valve seat, and the flow passage can be closed against the direction of fuel delivery by means of a check valve positioned in the area of the orifice opening into the mixing chamber.

    摘要: An internal combustion engine with a device for controlled recirculation of exhaust gas into intake ducts via an exhaust gas recirculation line connected to the engine's exhaust system. Rapid response behaviour is achieved by providing an exhaust gas recirculation port in each intake duct in the immediate vicinity of the cylinders, which port communicates with a distributing device supplied via an exhaust gas recirculation line, and by providing the distributing device with an adjusting element which is configured to jointly control the flow cross-sections of the exhaust gas recirculation ports.
