The following particulars refer to a 4 cylinder, 4 stroke petrol engine;

Bore = 65mm Stroke length = 95 mm; Toraue = 64 Nm @ 3000 RPM; Clearance volume = 63 cm3 for each cylinder; Relative efficiency = 0.5 Calorific value of Fuel = 42 MJ/kg. Calculate: (i) Brake mean effective pressure (ii) Fuel consumption in kg/hr.
