A gas engine working on Otto cycle has a cylinder of diameter $220 \mathrm{~mm}$ and stroke $300 \mathrm{~mm}$. The clearance volume is $1600 \mathrm{cc}$. Find the air-standard efficiency. Assume $c_{p}=1.004 \mathrm{~kJ} / \mathrm{kg} . \mathrm{K}$ and $c_{v}=0.718 \mathrm{~kJ} / \mathrm{kg} . \mathrm{K}$ for air.
