| 摘要 |
Invention relates to a method of operating an internal combustion piston engine (20), wherein combustion air is pressurized to a first pressure, and gaseous fuel is maintained at a second pressure in a fuel mixing chamber (16) for introducing gaseous fuel directly into the combustion chamber (26) of the engine (20). A first portion of the pressurized air is introduced into the combustion chamber (26) of the engine (20), a second portion of the pressurized air is injected into the fuel mixing chamber (16), and the second portion of the pressurized air injected into the fuel mixing chamber (16) is mixed with the gaseous fuel forming an air-fuel mixture, which is admitted to the combustion chamber (26) of a cylinder (22) of the engine (20) while the piston (24) of the cylinder (22) is at a region of the bottom dead center, and the gaseous fuel is ignited. The invention relates also to a charge admission system (10) for a super-charged internal combustion piston engine (20). |
