Asix cylinder 3.0 l diesel engine runs at 3000 rpm. the compression ratio of the engine is 17: 1. the engine in-cylinder process can be approximated by an air standard dual cycle with 30% fuel burned at constant volume and 70% at constant pressure. fuel is light diesel. assume combustion efficiency is 100%, volumetric efficiency is 90%, and mechanical efficiency is 80%. each cylinder has one injector with six holes of 150 micrometer in diameter. the discharge coefficient of the injector nozzle is 0.75. injection pressure differential across the nozzle is 1000 bar. injection duration is 15 crank angle degrees. what is the break power output for this condition? (intake air temperature is 60 and fuel density is 800 kg/m^3 ).
