  • G0501005 Fuel Spray Simulation of Fuel Injector with Outward Opening Valve

抄録

Effects of valve lifts on jet angles of fuel sprays from a fuel injector with an outward opening valve were studied. We previously developed a fuel spray simulation that combined an inner flow simulation in a fuel injector, a fuel breakup simulation near nozzle outlets, and an air/fuel mixture simulation. The fuel spray simulation was applied to study the effects of the valve lifts on jet angles of fuel sprays. The simulated results were validated with measure ones, and the jet angles quantitatively agreed well with measured ones. The jet angle near the nozzle outlet was determined by valve-surface taper angle y, and the jet angle in the air/fuel mixture region was done by the Re number.
