In a gasoline engine, a mixture of air and gasoline burns under approximately isochronous conditions. The pressure and temperature just before combustion are 1.3 MPa and 350 degrees Celsius. Approximate the process with 1 gram of clean air and heat transfer according to the figure. Determine the pressure just after combustion if the temperature then reaches 1800 Degrees Celsius and determine the heat Q 1.3 MPa 350 C
