INTERNAL COMBUSTION ENGINE

摘要

The engine comprises a cylinder with a piston arranged therein, said piston being connected to a connecting rod, and a crankshaft. A first elliptical gearwheel is rigidly fixed to the shaft with the possibility of interacting with a second elliptical gearwheel, which is rigidly fixed to an additional shaft. The distance from the pitch points of the wheel with the wheel to the axis of rotation of the wheel in the case of positions of the crankshaft corresponding to the location of the piston in the upper and lower dead points is 1.1-5 times the distance from the pitch points and to the axis of rotation of the wheel. The distance from the pitch points of the wheel with the wheel to the axis of rotation of the wheel in the case of positions of the crankshaft corresponding to the location of the piston in the centre of its excursion is 0.2-0.9 times the distance from the pitch points to the axis of rotation of the second wheel. The technical result consists in reducing the angular velocity of the crankshaft during movement of the piston in the region of the upper and lower dead points.
