A gasoline engine takes in 1.61 X 10^4 J of heat and delivers 3700 J of work per cycle. The heat is obtained with burning gasoline with a heat of combustion of 4.60X10^4 J/g. a) What is the thermal efficiency? b) How much heat is discarded in each cycle? c) What mass of fuel is burned in each cycle? d) If the engines go during 60.0 cycles per second, what is its power output in kilowatt? In Horse power?
