The friends decide to try a homework problem. The efficiency of the Otto cycle is given by e-1- specific heats of the gas-air mixture, y Ca/Cy. Recall that the work done by the engine is given by WengetQl (V₁/V₂-1 where the ratio of larger volume to smaller volume, V₁/V2, is the compression ratio, and where y is the ratio of malar Each cylinder in an automobile engine has a minimum volume of 45.0 cm³, and a maximum volume of 270 cm³ when the piston is fully down. The gas-air mixture in the engine has 7-140, and combustion of the fuel releases 1.22 x 103 per gallon. Assume an automobile engine operates with an idealized Otto cycle. What is the efficiency? x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. How much work can the engine do using a gallon of gasoline? x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. 1 Submit Skin (you cannot come back)
