A 4-cylinder, 4-stroke SI-engine has the following particulars from Morse Test: (20) bore = 6 cm; stroke = 9 cm; oil consumption = 0.13 Kg/min; The power measurements are as follows: With all cylinders firing 16.25 kW; with 1st. cylinder cut off = 11.55 kW; with 2nd. cylinder cut off = 11.65 kW; with 3rd. cylinder cut off = 11.70 kW; with 4th. cylinder cut off = 11.50 kW. Determine a) the IHP of the engine b) the mechanical efficiency c) indicated thermal efficiency if the calorific value of the fuel used is 42,000kJ/kg, d) indicated mean effective pressure and e) the relative efficiency (based on indicated thermal efficiency) if the clearance volume of a cylinder is 65cm³.
