Original methods for improving gas–air systems of turbocharged engines have been proposed. An analysis of the dependences of the gas-flow velocity and of the local heat-transfer coefficient in such a system on time has been made. As the criterion of assessment of the efficiency of these systems, use was made of the level of turbulence of gas flow in them and of the averaged coefficient of its heat transfer. Gasdynamic and heat-transfer characteristics of various modifications of the indicated systems have been considered.
