FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering and can be used in the construction of reciprocating internal combustion engines (ICE) with a thermodynamically variable compression ratio using gaseous or liquid fuel as fuel. Technical problem is solved by the method of increasing and adjusting within a wide range of the initial temperature of the intake air by using only one mechanical throttle valve of the mixer. Initial temperature changes due to the selection by heat exchanger of heat from the combustion products of the engine itself. Also in the engine is used the original de-axial crank-connecting rod mechanism, providing a long stroke of the piston, which significantly increases the geometric compression ratio necessary to achieve the claimed result.
EFFECT: task to which the present invention is directed is to significantly reduce the reaction time of the control mechanism, and also completely to refuse from change of geometrical parameters of the crank-conrod group during work of the engine, but at the same time preserve the thermodynamic characteristics of the engine with a geometrically variable compression ratio.
