FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to engine building, and can be used in production of two-stroke internal combustion engines. Above technical result is achieved due to the fact that the internal combustion engine includes a housing with a cylinder block, in each of which a piston and a connecting rod are installed along the cylinder axis. Crankshaft of engine is equipped with supports in the form of roller rolling bearings, wherein crankshaft of engine is made in form of integral cam shaft and is connected to pistons by solid crank rods. Latter, in their turn, are also equipped with supports in the form of roller rolling bearings. And on ends of cams of non-separable shaft there are split straps, which perform function of protection of rolling bearings and piston rods from axial displacement.
EFFECT: technical result is reduced complexity of the design of the proposed internal combustion engine by using an integral eccentric shaft with supports in the form of roller rolling bearings and non-assembled rods, also equipped with supports in the form of rolling bearings.
