An analytical method in which a new thermodynamic property-available energy is used has been introduced for energy utilization in diesel. At first, this method is used to analyse the perfomance of a diesel.The concrete calcu- lations are accomplished in two ways-the available energy equilibrium and the entropy increase. After having analysed the non-charged and turbo- charged diesel chosen, the author makes the corresponding histories and tables of the available energy equilibrium and gets the relatonship between the practical irreversable factors and the losses of available energy quantitatively. It is discussed what factors affect on the main irreversibilities and how far we may go foward on the way of decreasing these irreversibilities. By the calculation of changing the properties, it is sought what approaches are the most effective for decreasing the losses. Secondly, it is shown that the recovery of waste heat from diesel is very significant. Some different designs of the power recovery of waste heat from diesel are compared with the analytical method and the unperfect parts are shown for each design. The optimum de- sign is chosen according to the effect of the recovery of available energy. At last, it is shown that the development of the adiabatic compound engine is very significant.
