FIELD: engine engineering. SUBSTANCE: gear is mounted instead of a crank gear. The gear is rigidly secured to the crankshaft positioned at the horizontal symmetry axis of the device in ports of touching cylinders. The gear engages rod-pistons. The rod-pistons are provided with horizontal grooves that are correspond to the step and profile of a teeth of the gear to define a gear transmission together with the gear. EFFECT: enhanced efficiency. |
