Fuel injector for internal combustion engines and method for making same |
摘要 |
A fuel injector nozzle includes a nozzle body and a poppet disposed in the body for reciprocating movement. The body has an internal bore surrounding the poppet. The internal bore tapers in a constant angle of taper from a front seating region to a fuel reservoir region. The poppet has a corresponding surface which diverges slightly from the bore. The surfaces of the bore and poppet form flow control surfaces which terminate in a sharp-edged orifice at the front face of the nozzle. When the poppet is displaced to an open or flow position, fuel is accelerated to the orifice and atomized into a combustion chamber. The poppet surface being formed so as to properly direct fuel after the poppet surface is machined.
