Answer:
e=58%
Explanation:
Given data
The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8.
Solution
We want to calculate the ideal efficiency of the engine when ratio of heat capacity for gas used γ=1.40. Ideal efficiency (e) of the Otto cycle given by:
[tex]e=1-(\frac{1}{r^{Y-1} } )\\[/tex]
Substitute the given values to find efficiency e
[tex]e=1-\frac{1}{8.8^{1.4-1} } \\e=0.58\\[/tex]
e=58%
