This science article presents the competitive advantages of liquefied natural gas as a motor fuel used in internal combustion engines. Block diagram of interrelation of the influence of construction of aggregates, mechanisms and systems with the purpose of increasing the energy-efficient work of a gas engine is presented. Special attention in article is devoted to the research of critical parameters of pressure and temperature of liquefied methane in the mixture, with associated gases that are in a small fraction, as well as the determination of the heat capacity in the free-cooling mode of the fuel supply system of the gas engine and the cryogenic tank in the filled state in a special thermal insulation. Determination of the critical pressure and temperature parameters is considered under the condition that methane flows in a special round tube to supply gas in a two-phase form to the engine for further conversion of thermal energy to mechanical.
