A four-cylinder, four-stroke diesel engine develops a power of 180 kW at 1500 rpm. The bsfe is 0.2 kg/kW h. At the beginning of injec- tion pressure is 30 bar and the maximum cylinder pressure is 50 bar. The injection is expected to be at 200 bar and maximum pressure at the injector is set to be about 500 bar. Assuming the following Ca for injector S.G. of fuel Atmospheric pressure Effective preSsure difference 0.7 0.875 1 bar Average pressure difference over the injection period Determine the total orifice area required per injector if the inject ion takes place over 15 crank angles.
