| description | PROBLEM TO BE SOLVED: To obtain a spray while a penetration force of fuel to be injected is restrained in a fuel injection valve.SOLUTION: A fuel injection valve comprises: a valve seat forming a gap between it and a valve body, in which fuel passes through the gap; and plural injection holes nearer a downstream than the gap. The fuel, to which pressure is applied, flows from the injection holes. When a flow velocity of the fuel in the gap formed by the valve body and the valve seat is expressed by a meter per second, the flow velocity is set larger than a value obtained by multiplying a square root of the fuel pressure with 28, so that the flow velocity of the gap is increased and distribution of the flow velocity in the injection holes is made uniform, so as to restrain increase of penetration. |
