Let's begin with an efficiency analysis of a gasoline engine. The engine in a large truck takes in 2500 J of heat and delivers 500 J of mechanical work per cycle. The heat is obtained by burning gasoline with heat of combustion Le = 5.0 x 104 J/g. (a) What is the thermal efficiency of this engine? (b) How much heat is discarded in each cycle? (c) How much gasoline is burned during each cycle? (d) If the engine goes...
