摘要： A gaseous fuel internal combustion engine includes an engine housing defining at least one cylinder, and an intake housing defining an intake passage fluidly connecting with the at least one cylinder. The engine includes a gaseous fuel delivery mechanism coupled with the engine housing and a distributed ignition promoting mechanism having a bead presentation device extending into the intake passage and configured to present a liquid bead of distributed ignition promoting material therein such as engine lubricating oil. During operation, gases passing through the intake passage dislodge the liquid bead from the bead presentation device and carry the distributed ignition promoting material into the cylinder for distributively igniting therein a mixture containing a gaseous fuel, air and the distributed ignition promoting material.

摘要： An air induction system for an engine is disclosed. The air induction system has a compressor operable to compress air directed into the engine, a bypass valve, and a throttle valve. The bypass valve may be disposed between the compressor and the engine and may have a valve element movable to selectively divert a portion of the compressed air away from the engine in response to a desired air-to-fuel ratio of the engine. The throttle valve may be disposed between the bypass valve and the engine and may have a valve element movable to selectively restrict the flow of compressed air into the engine in response to a desired air-to-fuel ratio of the engine. The movements of the valve elements of the bypass and throttle valves may be substantially sequential.

摘要： A method of operating an engine is provided. The engine may have a housing with one or more combustion chambers, including a first combustion chamber. The engine may also have a piston in fluid communication with the first combustion chamber. The method may include combusting fuel in the first combustion chamber, thereby producing combustion gas that expands and drives the piston during a first combustion-gas-expansion stroke of the piston. The method may also include compressing at least part of the combustion gas in the first combustion chamber during a compression stroke of the piston. Additionally, the method may include, between commencement of the first combustion-gas-expansion stroke and completion of the compression stroke, releasing part of the combustion gas from the first combustion chamber. The method may also include, subsequent to completion of the compression stroke, expanding at least part of the combustion gas against the piston during an additional combustion-gas-expansion stroke of the piston.
