    Abstract: A system and method for the direct injection of a gaseous fuel into an internal combustion engine. The gaseous fuel injection system (10) delivers metered amounts of gaseous fuel directly into the combustion chamber of an engine. The injection system (10) is configured as a 'two-stage' system, comprising a gaseous fuel metering means (12) and a delivery injector (14). The metering means (12) is arranged coaxially with the delivery injector (14) such that gaseous fuel metered thereby can be received by the delivery injector (14) for subsequent delivery to the engine. A holding chamber (16) is arranged intermediate of the metering means (12) and delivery injector (14). Operation of the engine (30) and the injection system (10) is controlled by an engine control means comprising a suitably programmed electronic control unit. The injection system (10) is configured to promote operation of the metering means (12) with a sonic flow during the gaseous fuel metering event. For this purpose, a region downstream of the metering means (12) and within the injection system (10) is configured and sized to promote operation of the metering means (12) with a sonic flow during the gaseous fuel metering event. Specifically, the metering means (12) and the delivery injector (14) are arranged and/or configured to ensure sonic flow through the metering means (12) when it is opened and is metering gaseous fuel. The delivery injector (14) may also be arranged and/or configured so as to promote sonic flow throughout a gaseous fuel delivery event. Typically, the holding chamber (16) is configured to be of a sufficient volume to ensure sonic flow throughout the metering event.

    Abstract: A supplementary slurry fuel atomizer of this invention, when used on a piston internal combustion engine, equipped with a common rail fuel injection system, improves slurry atomization, following injection, by expansion of gases, previously dissolved in the water phase of the slurry. This gas expansion separates the several fuel particles in each slurry droplet formed first during fuel injection. The thusly separated fuel particles subsequently burn more rapidly and completely, due to this fuel particle separation improving air access to the fuel. Apparatus is described for dissolving atomizing gas into the water phase of the slurry, in a contactor chamber at a pressure greater than the pressure prevailing in the engine cylinder volume, at the time of slurry injection.
