    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 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.

    摘要： Digital fuel injector, injection and hydraulic valve actuation module and engine and high pressure pump methods and apparatus primarily for diesel engines. The digital fuel injectors have a plurality of intensifier actuation pistons allowing a selection of up to seven intensified fuel pressures. The disclosed engine operating methods include using at least one cylinder for a compression cylinder for providing compressed intake air to at least one combustion cylinder. A pressure sensor in each combustion cylinder may be used to indicate temperature in the combustion cylinder to limit combustion temperatures to below temperatures at which substantial NOX is generated. A re-burn cycle may be used to complete the burning of hydrocarbons, providing a very low emission engine. A compression cylinder may be provided with a pump actuated by the piston in the compression cylinder. Various aspects and embellishments of the invention are disclosed.
