FUEL INJECTION VALVE FOR DIRECT INJECTION SPARK IGNITION TYPE INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To improve the directivity of a spray directed toward an ignition plug when forming at least one spray directed toward the ignition plug and a plurality of sprays directed toward the lower side from the ignition plug by injecting fuel from a plurality of nozzle holes on a tip face of a fuel injection valve to inside of a combustion chamber. SOLUTION: A nozzle hole A1 of spray directed toward the ignition plug is arranged in the central part on the tip face of the fuel injection valve. Nozzle holes A2 to A4 of sprays directed toward the lower side from the ignition plug are arranged so as to be offset from the central part. COPYRIGHT: (C)2008,JPO&INPIT
