- the connection of the first switching means 9 with the second slider 11 by the first switching device 14 can be carried out, for example, by deflecting the rod 7 in the lateral direction at a given angle and with the following deviation of the first switching means 9 and its emphasis on the second slider 11.
- the journal 17 of the crankshaft 12 is at a point that is deviated from the point of the initial location of the journal 17 by 45> , which ensures maximum transmission of the pressure energy of the working mixture on the formed maximum shoulder.
- the rotation of the crankshaft 12 and the movement of the crossheads 16 in the grooves 15 move the first slider 11 in the direction of movement of the second slider 10 and combine it with the switching means 8 of the second cylinder 2 corresponding to the switching device 14.
- the first slider 11 performs the function of compressing the working mixture in cylinders 2 and 3, exerting pressure on the switching means 8 and 9 and the corresponding rods 6 and 7, and the second slider 10 performs the function of rotating the crankshaft 12.
- the first switching means 9 is combined with the first slider 11 by the first switching device 14 and the second slider 11 is moved to the side of the first cylinder 3 by rotating the crankshaft. shaft 12. During this operation, the first slider 10 is actually connected to both switching means 8 and 9.
- the second switching means 8 is combined with the second slider 11 by the second switching device 14. This movement of the second slider 11 is due to the activation of the device for igniting the working mixture 18 in the second cylinder 2, ignition mixture and its pressure on the piston 4 and rod 6.
- the connection of the second switching means 8 with the second slider 11 by the second switching device 14 can be carried out, for example, by deflecting the rod 6 in the lateral direction at a given angle a with the following deviation of the second switching means 8 and its emphasis on the second slider I.
- the neck 17 of the crankshaft 12 is at a point that is deviated from the point of the initial location of the neck 17 by 135 ⁇ , which ensures maximum transfer of the pressure energy of the working mixture to the formed maximum shoulder.
- the first slider 10 is moved to the side of the first cylinder 3 by rotation of the crankshaft 12 and the movement of the crossheads 16 in the grooves 15 and the above list of operations is repeated, making the above sequence of actions cyclic. If it is necessary to stop the operation of the device, the revolutions of the flywheel and crankshaft 12 or the activation of devices for igniting the working mixture 18 are stopped.
- the claimed device is a power drive, in which the kinematic connection between the pistons and the crankshaft is an improved Scottish mechanism.
- the claimed method by jumping the movement of the sliders while the pistons are at top dead center, it is possible to achieve the maximum energy transfer of the pressure of the working mixture in the cylinders to the maximum shoulder, which in turn leads to improve engine efficiency and reduce fuel costs.
- the design of the claimed device is simplified compared to four-cylinder power drives, which, in turn, makes it possible to simplify the method of converting reciprocating motion into rotational motion and vice versa, which is carried out using the claimed device.
- the proposed technical solution is industrially suitable, since it does not contain any structural elements or materials that cannot be recreated at the present stage of technology development in industrial production.
