A method and results of the analysis of exergy losses that occur in the exhaust system of a turbocharged diesel engine are presented. The aim of the work was to distinguish nodes in the system where exergy losses arise and make precise assessment of losses generated there. Losses were found to be attributable to three main sources: high velocity flow of viscous gas through variable geometry ducts; irreversibility of thermodynamic processes; and heat exchange through the walls of the exhaust system. The adopted model of generating exergy losses has made it possible to carry out a computer simulation for an exemplary turbocharged engine. The results are illustrated in diagrams and discussed.
