Abstract
Disclosed herein is a vehicular high pressure direct injection type injector with valve seat body for fuel-atomization. A nozzle hole has an elliptical cross-section so that the fuel injection speed can be increased, whereby a fuel atomization effect can be maximized. Furthermore, a stepped hole is formed under the nozzle hole so that the nozzle hole can be fundamentally prevented from becoming clogged with combustion byproducts.
