In particular, the limited amount of information in the Russian and foreign www.elsevier.com/locate/procedia literature can be found about the studies of heat transfer in the intake and exhaust pipes. Apparently, this can be explained by the fact that the gas exchange processes in piston internal combustion engines are unsteady and high- frequency processes, this greatly complicates scientific approaches to their study. Data about intensity of the instantaneous heat transfer are the basis for determination of heating of the air (at intake), cooling exhaust gas (at International Conference on Industrial Engineering, ICIE 2017 exhaust), calculation of thermal stresses in the nodes and details of intake and exhaust systems. However, data on International Conference on Industrial Engineering, ICIE 2017 instantaneous heat transfer is practically absent, so engineering calculations are performed on the basis of data on stationary flows. It is known that the heat transfer coefficient in unsteady conditions may differ from the stationary The Influence of Piston Internal Combustion Engines Intake and case in 2-4 times [1-6].
