Abstract (English):
According to the results of the study numeric val-ues of influence dynamics of the excess air factor on fuel consumption by diesel internal combustion engine have been received. Cause and effect relationships between the excess air factor and formation of a mix have been defined, optimum intervals of the excess air factor, temperature and air pressure in an intake mani-fold which provide optimum fuel consumption have been given. The mathematical model of fuel consumption de-pending on the excess air factor has been introduced. Studies carried out at the department "Operation of motor vehicles" of the Tyumen Industrial University show that the heating of air in an intake manifold of internal combustion engine KAMAZ 740 up to +67C the temperature interval of the minimum fuel ≤ 2,05 that gives fuel economy consumption increases from-25 to + 77 ° C when to 30 %, especially, at cars opera-tion in severe climatic conditions.
