FIELD: engines and pumps.
SUBSTANCE: internal combustion engine structure is proposed in which it is possible to change the compression ratio by changing the volume of the combustion chamber. Two cylinders are arranged opposite to common dismountable frame which reduces vibrations. The pistons in the cylinders are connected by rods and connecting rods with primary shafts and form together the eccentric mechanisms, (crankshaft analogue), which are arranged in the frame. The change of position of primary shafts in the frame results in the change of position of pistons in the cylinders and increase or decrease the volume of combustion chamber and the change of compression ratio. There is an electromechanical circuit for controlling the position of primary shafts in the frame depending on the number of revolutions of the internal combustion engine, which makes it possible to use the internal combustion engine in maximum power mode or in maximum efficiency mode.
EFFECT: increased power and efficiency.
