An engine working Otto cycle has aA compression ratio 8.2 to 1 beginning of the compression stroke .The condition inside the cydnders are Pressure = 93KN/m^3 abs, Temperature 13°C. The Maximum pressure in the cylinder is 320KN/m^3 abs .If gamma for the working substance is 1.4, Determining the pressure and temperature at which of the following points in the cycle:
1. End of compression stroke
2. Beginning of the compression stroke
3. End of expansion stroke
