A fuel of the chemical formula C10H20 was used to run a spark-ignition engine in a laboratory environment simulating the atmosphere of planet Mars. The intake air was composed of (O2 + 3CO2). Stoichiometric amounts of “air” and fuel enter the engine at 25C, while combustion products in the exhaust manifold are at an average temperature of 1000 K. Only products of complete combustion are found in the exhaust. It is measured that the engine produces 2.0 kW of power while the heat transfer rate to the surroundings is 1.0 kW. a) Determine the mass flow rate of the fuel supplied to the engine. b) Determine the fuel conversion efficiency of the engine when operated with the proposed fuel.
