A four$-$stroke gasoline engine is analyzed with the Air Standard Otto Cycle theory. The engine has a compression ratio of $8$:$1$ and the minimum cycle pressure is $1$ bar. The minimum and maximum cycle temperatures are $15\backslash$deg C and $1000\backslash$deg C$,$ respectively. Determine the following items by taking $,,$ and $=1\mathrm{.}4$:$($a$)$The maximum cycle pressure;$($b$)$The thermal efficiency; and$($c$)$The mean effective press
