      In internal Diesel combustion engine, The change of air temperature is change the density of air in the stoke volume to Diesel engine.
      The influence of power and efficiency is change according to the atmosphere- temperature of air.
      For calculating, decided the Diesel engine scale is 2000cc and 4cylinders mechanical compression ratio is 18 of Diesel engine.
      Our country, Atmosphere-temperature change is -20℃ in winter to 40℃ in summer.
      The density of air increase by the temperature drop and decrease by the temperature rises.
      Density change of air is appear mass change to the stroke volume in Diesel engine.
      The mass change is change the compression ratio of Diesel. engine.
      The compression ratio change is change the thermal efficiency and power of Diesel engine.
      In atmosphere-temperature -20℃, Compression ratio change 20.687 and thermal efficiency change 66.05%.
      In atmosphere-temperature 40℃, Compression ratio change 16.913 and thermal efficiency change 63.21%.
      The Compression ratio and thermal efficiency are increase to the low temperature.
      The results are as follows,
      1. The change of atmosphere temperature is change the density and mass of air and influence the power and thermal efficiency to the Diesel engine.
      2. For increasing the mass of intake air to influenced the power and thermal efficiency must be drop the temperature of intake air
      3. For drop the temperature of intake air, intake manifold must be set ahead of engine and order side of exhaust manifold.
