Question: The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8.
A. What is the ideal efficiency of the engine? Use γ=1.40. Express your answer using two significant figures.
B. The engine in a Dodge Viper GT2 has a slightly higher compression ratio of 9.6. How much increase in the ideal efficiency results from this increase in the compression ratio? Express your answer using two significant figures.
