Fuel injection valve

A fuel injection valve exerts disturbance separately on porous flow spray to improve micronizing and causes every spray non-interfere mutually to form two direction sprays with high dispersion and good micronizing to prevent hydrocarbon and so on from engine exhausting. The fuel injection valve (1)...

Summary:A fuel injection valve exerts disturbance separately on porous flow spray to improve micronizing and causes every spray non-interfere mutually to form two direction sprays with high dispersion and good micronizing to prevent hydrocarbon and so on from engine exhausting. The fuel injection valve (1) includes valve body (3), nozzle body (5) separated and connected with the valve body, jet orifice plate (6) with a plurality of fuel jet orifices (7, 8, 9, 10). At least one side of the valve body and nozzle body has surface on the connected position mutually. At least more than two fuel jet orifices are on the periphery of the intersection of tangent of surface contact point (position) and the jet orifice plate (6). Thus turbulent flow is generated on the upstream of the fuel jet orifice (7c),the micronizing of fuel is improved by the collapse of vortex (32) entering into the inner spray, the interference of spray is inhibited by causing the distance (L) among jet orifices leave above certain valve corresponding t
