A single-cylinder, four-stroke cycle, petrol engine is supplied with a fuel having an analysis by mass of carbon 84 per cent and hydrogen 16 per cent. Assuming the air supplied is just sufficient to burn completely the whole of the hydrogen to H20, 91 per cent of the carbon of CO, and the remaining 9 per cent of the carbon to CO,. determine per kilogram of fuel the mass of each of the actual exhaust gas constituents (a) the actual mass of air supplied (b) If the engine develops an indicated power of 9 kW at 42 revjs and uses 0.25 kg fuelj kWh, find the volume of air at 20°C and 0.1 MNjm? drawn into the engine per cycle. Air contains 23 per cent O2 by mass, R for air is 0.287 kJjkg K. [(a) 1.44 kg H20, 2.8 kg CO2, 0.176 kg CO, 11.45 kg N2: (b) 14.87kg airjkg fuel; 3.72 x 10-4 m³ A single-cylinder, four-stroke cycle, petrol engine is supplied with a fuel having an analysis by mass of carbon 84 per cent and hydrogen 16 per cent.
