The compression ratio of a spark ignition engine is $11.$ The total volume of the $4-$cylinder engine is $1600$ cm$3,$ the combustion chamber is $40$ cm$3$ and the maximum temperature is $2600$ K$.$ The temperature of the air entering the engine is $260$ K and the pressure is $100$ kPa. Find the other temperatures and pressures of the engine $($k$=1\mathrm{.}4,$ Cv$=0\mathrm{.}7).$
