An automobile engine consumes fuel at a rate of 29 L/hr and delivers 60 kW of power to the wheels. If the fuel has a heating value of 44,000 kJ/kg and a density of 0.8 g/cm³, determine the efficiency of this engine, and draw a conceptual schematic of the engine as discussed in class (with all interactions clearly labeled).
