The following data is given for a four-stroke, four-cylinder, diesel engine: = Cylinder diameter = 35 cm, piston stroke = 40 cm, engine speed = 315 rpm, IMEP = 7 bar, engine tor used = 43000 kJ/kg, air consumption = 30 kg/min, cooling water circulated = 90 kg/min, rise in tempe = 322°C, cp for exhaust gases = 1.1 kJ/ kg.K, ambient temperature = 22°C. cp for water = 4.2 kJ/ kg. Calculate (a) the mechanical and indicated thermal efficiency, (b) draw up heat balance sheet on min
esel engine: = eed = 315 rpm, IMEP = 7 bar, engine torque= 8 kN-m, fuel consumption = 80 kg/h, CV of fuel ater circulated = 90 kg/min, rise in temperature of cooling water = 38°C, exhaust gas temperature erature = 22°C. cp for water = 4.2 kJ/ kg.K. = y, (b) draw up heat balance sheet on minute and percentage basis.
