Abstract

Low exhaust emissions and fuel consumption, made DIESEL engines suitable for passenger car applications today and various concepts have been presented for mixture formation improvement that has very important influence on the combustion efficiency and fuel consumption. One of these concepts which is used recently is micro-hole group nozzle. Using of INJECTOR with micro hole nozzles, the atomization of fuel spray is improved and this leads to have better air fuel mixture and lower engine emissions. In the present research, effect of using this kind of INJECTOR nozzle holes has been studied numerically using AVL fire Software. For numerical simulation, spray break up and atomization models and problem boundary conditions have been validated using experimental results of similar works, then the effect of micro hole configuration and angle between holes on spray penetration, droplet size and vaporized mass were investigated for two configuration of a (one plane type) and b (two planes type). Results showed that for micro hole nozzle, increasing the angle between two holes would increase spray penetration and evaporated mass and decrease droplets Sauter mean diameter.
