Description

 The invention relates to internal combustion engines, in particular to internal combustion engines with positive ignition and self-ignition, and can be used in automobile engines.

Characteristics of analogues and prototypes
The rodless internal combustion engines, which are well described in the domestic and foreign literature and patent documentation of Russia, the USA, Japan and others, can serve as an analogue and prototype.

 An analogue of the invention is considered - US patent 5503038, class. F 02 B 75/22, publ. 04/02/1996. When considering this analogue, we came to the conclusion that a multi-eccentric device with free movement is designed to convert the rotational movement of the eccentric mechanism into rectilinear movement in the piston cylinder with rods, which can serve as a compressor using an independent energy source (electric motor, etc.). And also the analog device can serve as a rodless motor for converting the linear motion of the piston and rod into the rotational movement of the eccentric mechanism.

Since in the analog device, the cylinders are located crosswise, that is, each row is located perpendicular to each other (at 90 ^o ). Pistons in each row together with the rods move in the cylinder in the same direction. Therefore, the inertia forces of the piston and the rod that occurred at the end of the stroke (at the top or bottom dead center) will act in the same direction, with a double force, since the pistons and rods have the same mass. The occurrence of inertia forces of the analog device is not balanced by anything.

A similar layout scheme (cross-shaped and X-shaped) of a single-acting rodless engine with a different arrangement of cylinders was developed and well described in the literature by S. S. Balandin "Rodless internal combustion piston engines". M.: Mechanical Engineering, 1968, 151 pp. ) In this analogue, the cylinders are installed around the circumference of the crankcase at an angle of 60, 90, 180 ^o . Consider a multi-cylinder engine cannot be in-line, since the rod is one on two opposite sides of the crankcase, that is, the cylinders must necessarily be 180 ^o relative to each other. These engines can be used in aviation and other similar power plants, but cannot be used on cars because of the limited size of the engine compartment.

 This analog engine has the same disadvantages as the analog described above (US patent), that is, it does not have a mechanism for balancing the inertia forces of the first and second order arising during the movement of pistons with rods.

SUMMARY OF THE INVENTION
The developed rodless engine has cylinders that are horizontal. Additionally installed cylinders relative to those available at an angle of 180 ^o . This allows you to double the engine power, reduce metal consumption per unit of power, without changing the design of the crankshaft. In the rodless mechanism mounted on 4 cylinders (i.e. two pairs of cylinders) one balancing mechanism consisting of an eccentric 7 with a slider 8, which balances the forces of inertia. If a 6-cylinder engine, two balancing mechanisms are installed: the first between the first and second pair of cylinders; the second between the second pair and the third pair. With an increase in the number of cylinders, the number of balancing mechanisms increases.

 The use of the developed rodless engine on cars allows to increase the technical and operational characteristics of the car.

 Figure 1-3 shows a 4-cylinder engine with a horizontal arrangement (may be 6, 8 or more). This engine can be used in gasoline and diesel versions.

The rodless engine in which the proposed device is implemented consists of pistons 2 and 2 ¹ without skirts and bosses located horizontally on the same axis in cylinders 1 and 1 ¹ , which are interconnected via rods 3 and 3 ¹ and a common cam 4, freely rotating in the housing 11, to which the rods 3 and 3 ¹ are attached, an eccentric shaft 5 (prototype of the shaft elbows) and an eccentric support 7 integrated in the housing of the support 8, guides 6 of the piston rod and guides 9 in the support housing 8.

The work of the rodless engine with horizontally located cylinders is as follows: the piston 2 moves from the top dead center to the bottom dead center and transmits the movement to the piston rod 3, which together with the housing 11 moves along the guides 6 parallel to the cylinder wall 1, from the housing 11 the movement is transmitted to the rod 3 ¹ and piston 2 ¹ , which moves from bottom dead center to top dead center, in which case pistons 2 and 2 ¹ do not experience lateral loads; then the movement is first from the rod 3, and then from the rod 3 ¹ is transmitted to the eccentrics 4, which rotate freely in the housing 11. In turn, the eccentrics are mounted on the motor shaft 5 (the eccentricity of the crankshaft and the eccentrics 4 are equal to each other). Thus, the translational movement of the pistons is converted into rotational motion of the crankshaft 5, then to the flywheel 10 and the gearbox (propulsion).

 To ensure uniform engine operation, the inertia forces are balanced by installing a balancing mechanism between the cylinders, which is located between the eccentrics 4, where the eccentric 7 and the slider 8 slide along the guides 9 located perpendicular to the axes of the cylinders.
