ELECTRONICALLY CONTROLLED FUEL INJECTOR

摘要

PROBLEM TO BE SOLVED: To provide an electronically controlled fuel injector capable of stably supplying fuel in a combustion chamber of a single cylinder engine by linearly injecting the fuel toward the axis vicinity (the inner diameter center vicinity) of an inlet of an intake air port of the single cylinder engine. SOLUTION: This injector 2 is installed in a throttle body 5 in a state of inserting a tip part of an electromagnetic fuel injection valve (the injector) 2 having an orifice plate with a nozzle port for promoting atomization of atomizing fuel injected into the vicinity of an intake valve 22 of the single cylinder engine 1 into an installing hole 36 of an injector installing wall part 37 capable of 1inearly injecting the fuel toward the axis vicinity of the inlet of the intake air port 21 in the throttle body 5. The injector 2 is installed in the vicinity of a throttle valve 4 in the throttle body 5 to promote atomization of the fuel by using a flow (an air assist) of suction air.
