A gasoline engine is converted to run on propane as shown in Fig. P13.144. Assume the propane enters the engine at 25â—¦C, at the rate of 40 kg/h. Only 90% theoretical air enters at 25â—¦C, so 90% of the C burns to form CO2 and 10% of the C burns to form CO. The combustion products, also including H2O, H2, and N2, exit the exhaust pipe at 1000 K. Heat loss from the engine (primarily to the cooling water) is 120 kW. What is the power output of the engine? What is the thermal efficiency?
