FIELD: internal combustion engines.
SUBSTANCE: two-stroke two-cylinder internal combustion engine comprises a crankcase (1), pistons, mechanisms of pumping and connecting rod links and cylinders. The cylinders are divided by pistons into upper and lower chambers and separated from the crankcase (1) by removable covers with holes for the passage of rods. In the lower part of the cylinders, longitudinal and semi-circular grooves are made, connecting the upper and lower chambers. With a parallel arrangement of the axes of the cylinders, the shaft with the rocker arm and the output shaft are perpendicular to the axes of the cylinders and are located between them. At both ends of the rocker, grooves are made that contact through the hinges with the piston rods. Supports (8) with longitudinal slots for accommodating the ends of the rocker are fixed in the crankcase (1) and are made with a hole for installing the rods.
EFFECT: reduced friction.
