Abstract: The influence of variable thermobaric conditions on the component composition of compressed natural gas used as gas motor fuel in technological motor vehicles in the Republic of Sakha (Yakutia) has been studied. Boiling (condensation) temperatures of natural gas components were determined depending on their partial pressure at different total pressure of natural gas from 1 to 200 bar and temperature, which indicate the ability to partial condensation of a number of gas components. Initial data were obtained, changes in the component composition of natural gas in winter, spring and summer periods of time at different ambient temperatures at lowering the pressure in gas cylinders (from 200 to 50 bar) were studied and analyzed. Acceptable thermobaric conditions have been revealed, under which the optimal energy charge of natural gas supplied as fuel to the cylinder group of an internal combustion engine is preserved. At the same time, changes in the performance characteristics of internal combustion engines of technological transport in operating conditions at extremely low ambient temperatures of Yakutia are excluded.
