ELECTROMAGNETIC FUEL INJECTION VALVE AND COMBINED AIR-INTAKE TYPE ENGINE USING THE SAME

摘要

PURPOSE:To provide an electromagnetic fuel injection valve which may effectively distribute sprayed fuel from a fuel injection hole and which has a valve structure facilitates the machining of a nozzle part. CONSTITUTION:A spherical body attached to the front end part of a ball valve 10 is movably held in a fuel swivel element 18 which exerts swirl force to fuel. Further, a fuel injection hole 13 is formed in the valve shaft part of a valve guide 11 having a seat surface 12 which cooperates with the ball valve 10 so as to measure the fuel. Further, a protrusion 1 is provided coaxially with the fuel injection hole 13 in the valve guide 11, downstream of the fuel injection hole 13.
