FIELD: manufacture of engines, piston-type internal combustion engines in particular.
SUBSTANCE: crank mechanism of proposed internal combustion engine has webs in form of L-shaped rocker arm with crankpin secured on one end and rollers mounted on second end; rollers are engageable with pressure tracks driven by shaft. During working stroke, when action of pressure tracks is absent, crankpin rests against stop mounted on axle of bearing roller of crank which performs function of pivot axle of connecting rod axle. During working stroke, connecting rod axle may move away from stop on bearing roller axle under action of stages of pressure tracks; crankpin may stay on diameter of circle of rotation of crankpin axle.
EFFECT: enhanced operational efficiency of engine.
