摘要： An engine system includes a combustion chamber and an air supplier. The combustion chamber is formed in a cylinder. The air supplier is configured to supply air to a circumferential area of the combustion chamber. The circumferential area is near an inner circumferential surface of the cylinder. The air supplier is configured to supply air to the circumferential area before ignition to gather a rich air-fuel mixture that is present in the combustion chamber to a central area of the combustion chamber such that a stratified body consisting of a layer of the air-fuel mixture in the central area and a layer of the air in the circumferential area is formed.

摘要： A combustion engine has at least one cylinder with a gas exchange inlet valve and a gas exchange outlet valve. A fuel injection device injects fuel directly into the cylinder. A fresh air section can be connected intermittently for fresh gas transmission to the cylinder via the gas exchange inlet valve. An exhaust section can be connected intermittently for exhaust gas transmission to the cylinder via the gas exchange outlet valve. A throttle element is provided in the fresh air section ahead of the gas exchange inlet valve in the direction of flow of a fresh air. A fresh gas line is provided, which opens into the fresh air section after the throttle element, in the region of the at least one gas exchange inlet valve. The fresh gas line opens into the fresh air section via a nozzle, which has flow according to Bernoulli, Venturi or Coanda.

摘要： A method of operation of a dual fluid fuel injection system arranged to supply fuel to a cylinder of an internal combustion engine, the dual fluid fuel injection system being controllable to effect fuel metering events and fuel delivery events. The method comprises operating the dual fluid fuel injection system so as to have at least one fuel delivery event during each engine cycle and to have fewer than one fuel metering event, on average, per engine cycle. An electronic control unit for implementing the method is also described. The method and control unit allow dynamic range of a fuel metering injector, where included within the dual fluid fuel injection system, to be extended.

摘要： A straight port and a swirl port supply low-oxygen-concentration gas and high-oxygen-concentration gas into a combustion chamber of an engine such that high-level-oxygen-concentration gas and low-level-oxygen-concentration gas are formed from the high-oxygen-concentration gas and the low-oxygen-concentration gas in an adjacent region of the combustion chamber, which is adjacent to a fuel mist injected from an injection hole of a fuel injection valve. The high-level-oxygen-concentration gas is located in a corresponding area of the adjacent region, which is generally opposite from the fuel injection hole, and the low-level-oxygen-concentration gas is located in a remaining area of the adjacent region, which is other than the corresponding area of the adjacent region.
