PURPOSE:To make the gasification of fuel so satisfactory enough as well as to aim at stabilizing an engine output, by setting up a fuel injection valve so as to cause the sprayed fuel to be blown into a space between the inner wall of a suction passage and the valve body peripheral edge part of a throttle valve. CONSTITUTION:The axis of a setting hole 15' is to be formed up as far as an amount of X more eccentric to the left (see illustration) than both axes of a suction passage 2 and a throttle valve 3. Accordingly, in time of a small opening in the throttle valve 3, even if the fuel out of a fuel injection valve 6 is sprayed around in conicoid form, the sprayed fuel will not be blown so ample enough and a little to the inner wall of the suction passage 2 or a valve body 3a of the throttle valve 3 but blown instead well to a ringlike space S between the inner wall of the suction passage 2 and the valve body 3a of the throttle valve 3, then the sprayed fuel flows to the downstream side of the throttle valve 3 together with the speedy suction air running through the space S. |
