Internal combustion engine

The invention "relates to an internal combustion engine for is suitable for propulsion of motor vehicles and marine vehicles as well as for compressors.

There is already an internal combustion engine known, which consists of cylinders arranged in a row, which in immobile Gehär.3en are housed, in each of which two oppositely moving pistons are arranged, each of which is provided with rocker arms and push rods the crankshaft is connected.

The disadvantages of this internal combustion engine are that it is large. Dimensions, a complicated construction and has a large number of rocker arms, push rods and pistons, and a complicated and massive one Makes crankshaft with complicated machining necessary. In addition, it only allows a two-stroke process and the In-line arrangement of the cylinder blocks and requires the use of a compressor to blow through the working spaces.

The object of the invention is to provide an internal combustion engine to create in which the crankshaft has smaller dimensions, has a simpler construction 25th

3135552

and is easier to machine, which is the implementation of a four-stroke process with an arrangement of the cylinder blocks in one and in two rows and which does not require a compressor to blow through the work areas.

This task is solved by an internal combustion engine, the upper double-acting piston has the right in the upper row of immobile cylinder blocks and left cylinder heads are mounted, with the upper double-acting pistons through the upper links and the upper joints are connected to the upper ends of the rocker arms, while the lower ends of the rocker arms through the lower joints and the lower limbs with the lower double-acting pistons connected to those in the lower row of immovable cylinder blocks with right and left cylinder heads are mounted. The rocker arms have immobile supports around which their rotation takes place, while intermediate joints are arranged between the immovable supports and the upper joints. The intermediate joints are connected with push rods. The push rods are each through a knee with the supports of the Crankshaft connected. The immovable supports and the supports of the crankshaft are rigidly connected to the housing. The stationary supports are opposite the axes of the upper and lower rows of the stationary cylinder blocks symmetrically arranged »In the case of an embodiment of the immovable cylinder blocks in a row, the upper ones are Ends of the rocker arm with the upper joints and. their lower ends connected to the immovable supports, while they go through the intermediate joints with the push rods are connected.

The advantages of the internal combustion engine according to the invention are that they have a simple construction with small Dimensions and low mass is that the machining of the crankshaft is easy, that a four-stroke work cycle with the execution of the immovable cylinder blocks

in one and in two rows is possible and that a movement group can serve four work rooms.

The invention is explained in more detail, for example, with the aid of the drawings. Show it:

1 shows a kinematic diagram of a movement group of an internal combustion engine with a two-row arrangement the immovable cylinder blocks;

2 shows a kinematic diagram of a movement group of an internal combustion engine with the arrangement of immovable cylinder blocks in a row;

3 shows a section through a movement group of an internal combustion engine with a two-row arrangement the immovable cylinder blocks and

4 shows a section through a movement group of an internal combustion engine with an arrangement of the immovable Cylinder blocks in a row

The internal combustion engine according to the invention consists of an upper row of immobile cylinder blocks 1 with upper right cylinder heads 2 and upper left cylinder heads and a lower row of immobile cylinder blocks 1 'with lower right cylinder heads 2 ¹ and lower left cylinder heads 3'. Upper double-acting pistons 4 are mounted in the upper row of immovable cylinder blocks 1, the upper double-acting pistons 4 dividing the working spaces of the upper row of immovable cylinder blocks 1 into upper right working spaces 5 and upper left working spaces 6. In the lower row of immovable cylinder blocks 1 'lower double-acting pistons 4 ^{1 are} mounted, the lower double-acting pistons 4' the working spaces of the lower row of immovable cylinder blocks 1 'in lower right working spaces 5 ¹ and lower left working spaces 6 ^! share. The upper double-acting pistons 4 are connected by upper links and upper hinges 8 to the upper ends of rocker arms

tied together. The lower ends of the rocker arm 9 are at a two-row arrangement of the immovable cylinder blocks with lower joints 10 in an arrangement in connected to a row with immobile supports 11. By Intermediate joints 12, which the rocker arm 9 in the areas between the upper joints 8 and the immovable Share supports 11 in two parts, namely in upper parts and lower parts 14, the rocker arm 9 with the push rods 15 connected, while the push rods 15 with Knees 16 and supports of the crankshaft 17 are connected. The immovable supports 11 and the supports of the crankshaft 17 are rigidly connected to the housing 18.

The internal combustion engine works as follows:

During one revolution of the crankshaft, the knees 16 set the rocking levers 9 around the immovable supports 11 in a retreating circular motion through the push rods 15. The rocker arms 9 set the upper double-acting piston 4 and lower double-acting piston 4 ¹ in a reciprocating motion through the upper joints 8 or lower joints 8 'and the upper links 7 or lower links 7 ^f. In the event of combustion in the upper right working spaces 5 and the lower left working spaces 6 ^f or upper left working spaces 6 and lower right working spaces 5 ^f , the force of the combustion gases from the upper double-acting pistons 4 and lower double-acting pistons 4 ^! transferred to the knees 16 of the crankshaft of the internal combustion engine in reverse order.

The determinants of the movement of the upper double-acting piston 4 and lower double-acting piston 4 ¹ are a puncture of the length of the knee 16, the upper parts 13 and the lower parts 14 of the rocker arm 9, the push rods 15 and the distance between the immovable supports 11 and the supports of the crankshaft 17.
