An engine contains the case 4, in it diametrically placed rotating cylinders block 1, in which opposed pistons 2 connected with each other and with one-cranked shaft 3 are located. Each cylinder has one input-output window 11. The input-output windows of the case intended for one cylinder are located in respect to the input-output windows of the second cylinder under an angle 900, thus the block of cylinders by means of conic cogwheels 5, 6 and 7 is connected with cranked shaft and rotates in respect to it in an opposite direction.
