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 gaseous fuel injection system (10) for delivering metered amounts of gaseous fuel into the combustion chamber of an engine, and also a method for injecting gaseous fuel directly into a combustion chamber of an internal combustion engine. The gaseous fuel injection system (10) comprises a body structure (11) defining a holding chamber (13) from which a fluid mixture contained therein can be subsequently delivered by a delivery injector (15) into the combustion chamber. The delivery injector (15) has an inlet (16) communicating with the holding chamber (13) and an outlet (18) for communication with the combustion chamber. The holding chamber (13) is adapted to receive a quantity of gaseous fuel from a fuel source through an inlet port (17). The holding chamber (13) is also adapted to receive a metered quantity of a supplementary gaseous fluid through a metering means (21). In one arrangement, the supplementary gaseous fluid may function as a diluent for the gaseous fuel. When functioning as a diluent, the supplementary gaseous fluid may comprise an inactive gas which merely contributes volume to the mixture and performs no active function, or alternatively may perform an active function within the mixture, as for example, an oxidant. The gaseous fuel incorporated in the injected mixture may comprise the sole fuel requirement for the combustion process. Alternatively, the gaseous fuel incorporated in the injected mixture may augment, or be augmented by, another fuel delivered into the combustion chamber for the combustion process.

摘要： An internal combustion engine (10) has at least one combustion chamber (15) defined by a piston (13) accommodated in a cylinder (11). The method of operating the engine (10) comprises opening an exhaust means (30) as the combustion chamber (15) expands to permit fluid to discharge from the combustion chamber (15), opening an inlet means (20) as the combustion chamber continues to expand to admit the intake air into the combustion chamber (15); closing the exhaust means (30) as the combustion chamber still continues to expand to interrupt discharge of fluid from the combustion chamber (15), and closing the inlet means (20) to interrupt admission of the intake air into the combustion chamber (15). With this operating sequence, scavenging of the combustion chamber (15) is incomplete and so there is a relatively large residual fluid within the combustion chamber.
摘要翻译：内燃机（10）具有由容纳在气缸（11）中的活塞（13）限定的至少一个燃烧室（15）。操作发动机（10）的方法包括当燃烧室（15）膨胀时打开排气装置（30），以允许流体从燃烧室（15）排出，当燃烧室继续时打开入口装置（20）膨胀以允许进入空气进入燃烧室（15）; 当所述燃烧室仍然继续膨胀以中断来自所述燃烧室（15）的流体排放时，关闭所述排气装置（30），并且关闭所述入口装置（20）以阻止所述进气进入所述燃烧室（15）。通过该操作顺序，燃烧室（15）的清除是不完整的，因此在燃烧室内存在相对较大的剩余流体。
