*27. mmh A diesel engine does not use spark plugs to ignite the fuel andair in the cylinders. Instead, the temperature required to ignite the fueloccurs because the pistons compress the air in the cylinders. Supposethat air at an initial temperature of 21 °C is compressed adiabatically to atemperature of 688 °C. Assume the air to be an ideal gas for which y =.Find the compression ratio, which is the ratio of the initial volume to thefinal volume.

The ideal gas is, PiViγ=PfVfγThererfore,PV=nRTP=nRTV

A monatomic gas in a certain gasoline engine undergoes an Otto cycle. a.) Assume that the pressure is increased by a factor of 1.5 during the adiabatic compression stroke, so that the pressure after this step is P2 = 1.5 P1, where P1 is the initial pressure. Write an equation for the volume V2 in terms of the volume before this step V1. b.) Write an equation for the temperature T2 after the adiabatic compression in terms of the temperature T1 before this step. c.) Assume the pressure is doubled after the isochoric step, such that the pressure after this step is P3 = 2.0 P2. Write an equation for the temperature after this step T3 in terms of a number (carried to two digits) multiplied by the temperature T2 before this step.
