ABSTRACT:
Disclosed is an improvement of electromagnetic type fuel injection valve comprising: a cylindrical housing having a stationary core therein; an annular yoke positioned in the vicinity of the opening end of the housing; a coil positioned in the space defined by the housing, the stationary core and the yoke; a valve seat piece having a needle valve put therein, the valve seat piece being positioned ahead of the yoke, and comprising a valve seat and a fuel metering-and-injecting aperture consecutive to the valve seat to be opened and closed by the front end of the needle valve; and a movable plunger integrally connected to the rear end of the needle valve, opposing the end of the stationary core. The fuel injection valve is designed according to the present invention so that the flow rate at which the fuel is injected from the fuel injection valve when fully opened is 20 L/H with the fuel metering-and-injecting aperture having a maximum effective injection area of 0.3 mm.sup.2, and that the product of L.times.D ranges from 1.8 cm.sup.3 to 3.6 cm.sup.3, where L stands for the longitudinal length of the magnetic path formed by the housing and the yoke, and D stands for the diameter crossing the longitudinal length L.
