A new diesel engine that increases fuel economy over previous models is designed. Automobiles fitted with this design become incredible best sellers. Two design features are responsible for the increased fuel economy: (1) the engine is made entirely of aluminum to reduce the weight of the automobile, and (2) the exhaust of the engine is used to prewarm the air to 50C before it enters the cylinder to increase the final temperature of the compressed gas. The engine has a compression ratiothat is, the ratio of the initial volume of the air to its final volume after compressionof 14.5. The compression process is adiabatic, and the air behaves as a diatomic ideal gas with = 1.40.arrow_forward
