Abstract
The present invention relates to a fuel injection system driven by compressor. The system is used in two-stroke gasoline engine, wherein high speed air flow is applied to assist in fuel atomization and injection. The system works in such a manner that a fuel pump and fuel pressure regulating valve establish stable fuel injection pressure and fuel is injected under this stable pressure by a main fuel injector and a sub-fuel injector. The fuel is not directly injected into the cylinder, but blown into main combustion chamber of the cylinder and pre-combustion chamber of a torch-forming plug by little amount of high speed air flow supplied from a small compressor synchroinzed with the engine in operation, the high speed air flow being distributed by a distributor to flow into air passages of the main fuel injector and sub-fuel injector for blowing the injected fuel. The ignition is performed in such a manner that the pre-mixed fuel air mixture in the pre-combustion chamber is first ignited by the spark plug and is injected from a lower passage of the torch-forming plug in a flame pattern with specific shape to successively ignite pre-mixed fuel air mixture in main combustion chamber.
