Abstract:
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.
Method And Apparatus For Regulating Gas Entrainment In A Fuel Injection Spray Of An Internal Combustion Engine
A technique is provided for regulating gas entrainment into a fuel spray in a fuel-injected engine. The fuel spray issues from a nozzle positioned in a gas entrainment shrouding recess, such as in the cylinder head. The depth and elevational profile of the recess are selected to provide a desired degree of gas entrainment. By reducing gas entrainment, a desired spray shape may be established or maintained, such as a hollow cone. More gas entrainment may be provided by altering the recess geometry, and that of the combustion chamber surrounding the recess, to modify the spray or the spray distribution, such as to partially or fully fill a spray cone.
