    • A compression ignition engine (20) has a control system (26) for processing data, one or more combustion chambers (22), and fuel injectors (24) for injecting fuel into the combustion chambers. The control system controls fueling using a result of the processing of certain data, such as engine speed and engine load, to select one of two fueling modes (HCCI, HCCI-CD) for operating the engine. When the result of the processing selects the HCCI mode, the engine is fueled to cause homogeneous-charge compression-ignition (HCCI) combustion within the combustion chambers. When the result of the processing selects the HCCI-CD mode, the engine is fueled to create a substantially homogeneous combustible charge within each combustion chamber that is compressed to auto-ignition, and after auto-ignition, more fuel is injected to provide additional combustion in the manner of the conventional diesel combustion.
    • 压缩点火发动机(20)具有用于处理数据的控制系统(26),一个或多个燃烧室(22)和用于将燃料喷射到燃烧室中的燃料喷射器(24)。 控制系统使用诸如发动机转速和发动机负荷的某些数据的处理结果来控制加油,以选择用于操作发动机的两种加油模式(HCCI,HCCI-CD)中的一种。 当处理结果选择HCCI模式时,发动机被燃料以在燃烧室内引起均质充气压燃(HCCI)燃烧。 当处理结果选择HCCI-CD模式时,发动机被燃料以在每个燃烧室内产生基本均匀的可燃物,其被压缩到自动点火,并且在自动点火之后,喷射更多的燃料以提供额外的燃烧 以常规柴油燃烧的方式。
