を特徴とする電磁式補助燃料噴射弁。 It has a plunger that is reciprocatably inserted into the fuel passage pipe, a valve is configured between the valve seat surface at the tip of the fuel passage pipe and the tip of the plunger, and a solenoid coil is provided on the outer periphery of the fuel passage pipe. This is a type of electromagnetic fuel injection valve in which the valve is normally closed by a spring force, and when the solenoid coil is energized, the plunger moves by electromagnetic force to open the valve, and when the valve opens, fuel is injected from the valve. In an electromagnetic auxiliary fuel injection valve in which the solenoid coil is energized when the internal combustion engine is started in a low-temperature period, and at least the tip of the solenoid coil is assembled into the surge tank of the intake pipe, the solenoid coil also serves as a yoke. An electromagnetic auxiliary fuel injection valve characterized by being covered with an integral cover made of ferromagnetic material.
