VEHICULAR HIGH PRESSURE DIRECT INJECTION TYPE INJECTOR WITH VALVE SEAT BODY FOR FUEL-ATOMIZATION

摘要

The present invention relates to a vehicular high pressure direct injection type injector with a valve seat body for fuel-atomization, and more particularly to a vehicular high pressure direct injection type injector with a valve seat body for fuel-atomization, wherein the cross section of the nozzle is formed elliptical to increase the speed of injecting fuel so as to maximize the effect of atomizing fuel, and a step hole is formed in the lower end of the nozzle hole so as to prevent the by-product of burning from blocking the nozzle hole.
