A gasoline engine operates steadily on a mixture of isooctane and air. The air and fuel enter the engine at 25 C. The fuel consumption is 0.15 g/s. The output of the engine is 1.0 kW. The temperature of the combustion products in the exhaust manifold is 700 K. At this temperature, an analysis of the combustion products yields the following values (on a dry volumetric basis). CO = 2.9%; CO2 = 11.4%; O2 = 1.6%; N2 = 84.1% a) Find the number of moles of each of the reactants and the products species per mole of isooctane. N. B. Use O2 + 3.76N2 as air; equation will not perfectly balance. b) Determine the heat transfer rate from the working fluid as the working fluid passes through the engine.
