A low speed-two stroke Diesel engine has six cylinders, with bore D=0.90m and stroke length L =2.5m. Its brake mean effective pressure rate is 1.8MPa and its crankshaft rotates at 180rpm. Turbocharger provides 100kPa gauge pressure air, cooled to 27C. It operates with an air/fuel ratio of 30 , and consumes a fuel with 42MJ/kg LHV. Find: a. Shaft power b. Torque generated c. Mean piston speed d. Thermal efficiency e. Specific fuel consumption For air : R=287J/kgK,k=1.40,cp=1.005kJ/kgK,patm=101.3kPa 2. For pure carbon burning in air with complete combustion, a. Write the chemical reaction b. Find the stochiometric air/fuel ratio c. Find Higher heating value (HHV) d. Lower heating value (LHV) of carbon e. Compare your findings with Dulong's equation Atomic weights : Carbon : 12, Hydrogen : 1, Oxygen : 16, Effective Nitrogen : 29 Enthalpy of formation for Carbon dioxide : - 393520kJ/kmole
