An engine with a compression ratio of 8.9: 1 draws in air at a temperature of 20 °c and pressure of 1 bar. estimate the temperature and pressure at the end of the compression stroke. why will the temperature and pressure be less than this in practice? the gravimetric air/fuel ratio of 12: 1, and the calorific value of the fuel is 44 mj/kg. assume that combustion occurs instantaneously at the end of the compression stroke. estimate the temperature and pressure immediately after combustion
