The improvement of work processes of piston engines to boost the technical and economic parameters is the main objective in the field of power engineering. The improvement of the gas exchange processes (intake and exhaust processes) quality is one of the possible profiles to improve the efficiency and reliability of piston internal combustion engines. The study of the instantaneous local heat transfer at flow unsteadiness is one of the objectives of the experimental studies of the thermomechanical processes in the intake and exhaust systems of the engines. The influence of configuration of the intake and exhaust pipes on the heat transfer intensity is a relevant engineering problem. Through experimental analysis and computational simulations, the paper describes the behavior of the gases and the heat exchange between the walls of the intake system and the air-fuel mixture. The study also considers the effects of varying engine operating conditions on the gas dynamics and heat transfer in the intake system. The results provide valuable insights for improving the performance and efficiency of internal combustion engines.
