Fuel Injection Valve
Abstract: An injection hole 36, a swirl chamber 41, and a swirl passage 42 of an injection hole plate 35, which is a leading end portion of a fuel injection valve 1, are set in such a way that fuel sprays injected from two neighboring injection holes 36 interfere on an upstream side of a position at which the fuel sprays break up from a state of a fuel liquid film 51 and become a fuel liquid ligament 52. The hollow conical form fuel liquid films 51 are of uneven circumferential direction thickness, and interfere with each other avoiding portions 51a wherein the circumferential direction thickness is greatest, because of which worsening of atomization due to interference between fuel liquid films 51 can be restricted. Also, the distance between neighboring injection holes 36 can be reduced, because of which a more compact overall fuel passage is achieved, and dead volume can be reduced, whereby an improvement in fuel spray atomization at an initial injection stage is achieved.
