In a gasoline engine, the compression temperature is 600 K and the compression pressure is 14 bar. At this stage, with the ignition of the spark plug, the octane (C8H18) used as fuel reacts with the 120% theoretical air present in the cylinder and combustion takes place. The process takes a very short time and the heat and work exchange from the cylinder to the environment is negligible (U2=U1). Accordingly, calculate the in-cylinder pressure reached as a result of the combustion process and also show it with EES software.
