ABSTRACT:
Fuel in a fuel tank is pressurized by a fuel pump and supplied to a fuel gallery. When a fuel injection valve connecting with this gallery is opened by an electromagnetic signal, fuel is injected from the valve into a combustion chamber of the engine. The fuel gallery is formed inside a cylinder head, and the fuel injection valve is disposed in the cylinder head such that a fuel inlet port of the valve faces the gallery. In this manner, a high pressure fuel passage does not project outside the cylinder head, and there is less risk of fuel leaking from the passage. Further, as the high pressure fuel passage does not project outside the engine, the piping around the engine is simplified.
