A test was conducted on a 4-stroke four cylinder engine having 6.9 cm diameter and 8.9 cm stroke. The fuel supply to the engine is 0.065 kg/min. The B.P measurements are given below with constant engine speed of 300 rpm: With all cylinder firing = 16.9 kW Cut off at 1st cylinder = 8.46 kW Cut off at 2nd cylinder = 8.56 kW Cut off at 3rd cylinder = 8.6 kW Cut off at 1st cylinder = 8.46 kW If clearance volume is 70 cm3 then find the mechanical efficiency, Indicate Power, Indicated thermal efficiency, Indicated mean effective pressure and also comment about the engine type whether it is SI or CI? Take Calorific value of fuel = 43500 kJ/kg
