ROTOR-PISTON INTERNAL COMBUSTION ENGINE

The utility model relates to mechanical engineering, namely to internal combustion engines.

Known rotary piston internal combustion engine Evladova S.P. (RU No. 12183, Cl. F 01 B 1/06, 1999), comprising a housing inside which a rotor is installed in the form of an equilateral polyhedron with an odd number of broken faces and an even number of cylinders, on the piston rods of which pressure rollers are fixed.

A disadvantage of the known device is the complexity of the manufacture of the rotor and the inconvenience during operation due to the arrangement of the cylinders crosswise, I create1; their single part is a complex configuration.

The objective of the utility model is to develop a more compact device that allows you to expand the application of the engine in the automotive industry, as well as reduce the complexity of its manufacture and improve performance.

The problem is achieved in that in a rotary piston internal combustion engine containing a housing inside which a rotor is installed in the form of an equilateral polyhedron with an odd number of broken faces and an even number of cylinders, on the piston rods of which pressure rollers are fixed, according to a utility model, the rotor contains two equilateral polyhedrons fixed rigidly, coaxially on one shaft and rotated relative to each other by 30 °, while at each vertex of the polyhedral rotor they are fixed with the possibility of rotation rollers, the rotation centers of which form a multilateral triangle, and the cylinders are located opposite two pairs symmetrically with respect to the axis of rotation of the motor shaft.

The execution of the rotor in the form of two} equilateral polyhedrons allows you to change the layout by arranging a vertical pair of cylinders horizontally, which allows to reduce the vertical size and facilitate access to the cylinders during operation. The presence of rotating rollers at the tops of the rotor interacting with the rollers on the piston rods makes it possible to increase the efficiency of the engine by reducing the friction force when the pistons pass the top dead center (TDC). The geometry of the rotor parts is greatly simplified due to the elimination of complex curved sections on the faces of the rotor.

The utility model is illustrated by drawings, where in FIG. 1 rotary piston engine, cross section; figure 2 is a section along aa.

The rotary piston internal combustion engine comprises a housing 1, inside of which a rotor 2 is installed, consisting of two parts coaxially fixed rigidly on one shaft 3 and rotated by 30 ° relative to each other. The shape of each part of the rotor 2 is made in the form of an equilateral polyhedron with an odd number of broken faces 4. At each vertex of the rotor 2 are fixed, rotatably, rollers 5, the rotation centers of which in plan form an equilateral triangle. An even number of cylinders 6 are arranged in pairs and opposite to each other inside the housing 1, on the rods 7 of the pistons 8 of which the pressure rollers 9 are fixed.

The device works as follows.

At the time of starting the engine, the rotor 2, rotating clockwise, acts face 4 on the pressure roller 9, mounted on the rod 7, shifting the piston 8 toward the top dead center. The roller 5, mounted at the top of the rotor 2, is on the same axis with the pressure roller 9 and the motor shaft 3. When this occurs, the ignition of the working mixture in one of the cylinders 6 - (I), and the piston 8 begins to make a stroke, acting through the pressure roller 9 on the rotor 2 and

at the same time, to the piston 8 of cylinder II, which is opposite to it, through the rod 7. One working stroke of one piston 8 rotates the engine shaft 3 by 60 °, and, after turning the shaft 3 by the first 30 °, the working mixture ignites in the cylinder 6 - III of the other opposed pair . Since the number of vertices of the rotor 2 is odd, then for one revolution of the shaft 3 of the engine 12 working strokes of the pistons 7 are performed, i.e. every 30 ° of rotation of the shaft 3 of the engine. Both parts of the rotor 2, rotating synchronously, include the cylinders 6 in the following sequence (I; III; II; IV), thereby ensuring smooth operation of the engine.

The utility model is present; its time is at the stage of a technical proposal.
