Diesel Spray Liquid Length Imaging at High Pressure

Engine efficiency and emissions depend on the fuel atomization dispersion. The dispersion heavily ambient pressure temperature. In this work, to study Diesel sprays in engine conditions, an electrically heated, constant-volume, pressurized vessel was designed manufactured. controlling electronics software were developed tested ensure safe precise operation. A commercial Bosch six-hole automotive injector used. spray spatial temporal development studied. literature, liquid length cone angle are extensively used quantify these parameters quantified using a high-speed shadowgraph technique. Models derived describe evolution of core. Such models can be predict behaviour performance.
