EFFECT OF FRICTION MECHANICS AND OF HEAT TRANSFER ON THE PERFORMANCE OF AN INTERNAL COMBUSTION ENGINE WORKING IN MIXED CYCLE

摘要

In this article, the irreversibility of the mixed cycle is presented. A consideration of mechanical frictions during the cycle of the internal combustion engine as well as the heat transfer through the walls of the combustion chamber during the contribution of the heat are modeled. A numeric analysis of the efficiency and the power in terms to the compression ratio for various values of the parameters of heat transfer and mechanical friction reflects the real characteristics of functioning of an internal combustion engine.
