A8 cylinder, 4 stroke diesel engine has a power output of 368 kW at 800 rpm. The fuel consumption is 0.23$ kg/kW.hr. The pressure in the cylinder at beginning of injection is 35 bar and the maximum cylinder pressure is 00 bar. The injector is expected to at 210 bar and the maximum pressure in the injector is set to be 600 bar Calculate the orifice area required per injector if the injection take place over 12° crank angle. Assume the coefficient of discharge for the injector 0.6, specific gravity of fuel 0.85 and the atmospheric pressure 1.013 bar. Take the effective pressure difference to be the average pressure difference over the injection period.

Q2/ A 8 cylinder, 4 stroke diesel engine has a power output of 368 kW at 800 rpm. The fuel consumption is 0.23 kg/kW.hr. The pressure in the cylinder at beginning of injection is 35 bar and the maximum cylinder pressure i 60 bar. The injector is expected to at 210 bar and the maximum pressure in the injector is set to be 600 bar Calculate the orifice area required per injector if the injection take place over 12° crank angle. Assume the coefficient of discharge for the injector 0.6, specific gravity of fuel 0.85 and the atmospherie pressure 1.013 bar. Take the effective pressure difference to be the average pressure difference over the injection period.
