VALVE-COVERED-ORIFICE (VCO) FUEL INJECTION NOZZLE DELIVERY ANALYSIS
ABSTRACT
This article derives analytical expressions based on a simplified analysis specifying the needle lift-time relationship and the instantaneous injection pressure which permit the fuel delivery rate, total fuel delivered per injection, and jet penetration prior to jet breakup to be evaluated for valve-covered-orifice (VCO) diesel fuel injection nozzles. This type of injection nozzle is becoming popular for use in diesel engines of advanced design. Comparisons are made to measured data from several sources with good agreement. The effect of needle eccentricity on fuel delivery is also illustrated.
