Description

The alleged invention relates to piston machines, in particular, to internal combustion engines with a rodless mechanism for converting the reciprocating motion of the piston into rotational motion of the flywheel.

A significant drawback of the existing internal combustion engines is the process of converting the translational motion of the piston into rotational motion of the crankshaft, which prevents the creation of engines with two-sided working process in the cylinders.

The closest technical solution is an internal combustion engine with a rodless mechanism, containing a cylinder, a piston / Japan patent No. 64614, class. F02B 53/00 dated 10.12.1973 /.

The disadvantage of this engine is the complex conversion mechanism.

The technical problem and the technical result of the proposed invention is to simplify the design and increase the specific power due to the pulse mechanism of converting translational motion into rotational movement of the flywheel.

The specified technical result is achieved in that in an internal combustion engine comprising a cylinder, a piston with a power mechanism connected by means of a gear to a flywheel, an ignition and exhaust system, a feature is that the piston is inserted into a finger, the free end of which is through a sliding bearing connected to a power mechanism made in the form of a gear mounted outside the cylinder with the possibility of moving along the sliding bearing and making oscillating motion along the flywheel arc .

The proposed power mechanism makes it possible, when using double-acting cylinders, to use an effective piston cooling system with forced oil circulation. The power mechanism is made in the form of a gear mounted outside the cylinder with the possibility of moving along the sliding bearing and making oscillating motion along the flywheel arc. Due to this oscillatory motion, the linear velocity of the piston along the cylinder from TDC to HMT (V ₁ ), and vice versa from BDC to TDC (V ₂ ) are different, V ₂ > V ₁ at a constant speed of rotation of the flywheel. This mechanism can be used not only for internal combustion engines, but also for drive compressors, pumps and other reciprocating machines.

The proposed power mechanism is shown in the drawings, where:

The internal combustion engine comprises a cylinder 1 piston 2 with a power mechanism made in the form of a gear mounted outside the cylinder 1 and mounted on the finger 4 of the piston 1 with the possibility of moving along the sliding bearing and making an oscillatory motion along the flywheel 5. The finger 4 is rigidly connected to the piston 2 and through the bearing 6 with the gear 3. The ignition system includes candles connected to the generator (not shown in Fig.), Compression and oil scraper rings 7, valves 9 for supplying a combustible mixture to the combustion chamber and exhaust exhaust .

The engine operates as follows.

When the combustible mixture is combusted in the upper combustion chamber of cylinder 1, the piston 2, under pressure from the burnt gases, moves downward by moving gear 3 through the finger 4, which, moving horizontally along the sliding bearing 6, starts to fly the flywheel 5 through the gear transmission (Figs. 3, 4 , position I; II). When a combustible mixture is burned (FIGS. 5, 6, positions III and IV) in the lower combustion chamber of cylinder 1, the piston under the pressure of the burnt gases performs a reverse movement by moving pin 4, gear 3 horizontally around the circumference of the flywheel 5 and bearing 6, which continues to rotate through gear flywheel 5.

The linear velocity of the piston 2 from TDC to BDC (V ₁ ) and from BDC to TDC (V ₂ ) is different V ₂ > V ₁ at a constant rotation speed of the flywheel 5.

The gear makes an oscillatory motion along the flywheel’s arc 5 - due to this oscillatory motion, the linear speed of the piston 2 along cylinder 1 from TDC to BDC and vice versa is different at a constant speed of rotation of the flywheel 5.
