| Abstract: | This paper put forward an exergy equilibrium calculation method of diesel engine, in which the exergy losses between the working substance and the cooling agent because of difference in temperature heat transmission can be calculated, according the features of engine cycle of diesel engine. The calculation results show that the major channels of improving exergy efficiency of internal combustion engine are to reduce exhaust losses, reduce heat transmission losses and improve combustion of the fuel. |
