EXERGY COEEFICIENT OF ECONOMIC UTILIZATION OF THE HEAT FROM ENGINE-BURNT FUEL
Methodical procedures are suggested to estimate the degree of economic utilization of the fuel burnt up in an engine. The procedures suggested allow to estimate the degree of thermodynamic perfection of a machine in whole, or each aggregate separately. Using the exergy of waste gas heat allows to increase the coefficient of heat utilization up to 90 % in the period of machine heating.
