Description

 The invention relates to the field of transport engine and other areas of the national economy.

 A four-stroke crank engine is known, which, along with positive qualities, such as quick start under normal conditions, subsequent perception of full load, significant braking torque, has disadvantages such as a relatively high crankshaft rotation speed during start-up and the impossibility of directly connecting it to the drive consumer wheels, the reciprocating movement of the piston, limiting the frequency of rotation and causing the appearance of unbalanced inertia forces and cops from them.

 The purpose of the invention is to eliminate these disadvantages, simplify the design, reduce weight and dimensions, and also increase power and compression ratio.

 To achieve this goal, a disk-piston single-stage four-stroke internal combustion engine containing a housing, cylinders with pistons and rods, a gas distribution mechanism, has, for example, 24 piston cylinders located at both ends in a cylindrical housing uniformly inscribed in its outer diameter, the axes of which are parallel to the shaft the engine, and the cylinder rods have on their free end rollers in contact with the sinusoidal tracks of the end surfaces of the rotor disk, rigidly mounted on the shaft, each pair of opposite of the living cylinders is located on the same axis, and the rods of each two adjacent opposing cylinders are connected by the ends of the two-arm pendulum rocker fixed motionless in the middle part, and the supra-piston space of each of the group of cylinders located in one working cycle is connected from both ends of the housing to one of four common combustion chambers made in the form of a torus.

In FIG. 1 shows a general view of the engine, a section in the axial plane; in FIG. 2
transverse section of the engine in a group of cylinders operating synchronously in one cycle; in FIG. 3 scan of the sinusoidal track of the disk rotor; in FIG. 4 pendulum mechanism.

 The proposed engine consists of a cylindrical housing 1, in the outer diameter of which 12 pairs of opposite cylinders 2 are uniformly inscribed, the axes of which are parallel to the shaft 3 of the engine mounted in the housing on bearings, on which the disk rotor 4 is fixedly mounted, on whose end surfaces sinusoidal tracks 5 are made. The over-piston spaces of each of the six cylinders operating synchronously in one cycle are connected by channels 7 to a common combustion chamber 6 made in the form of a torus. The rods 8 of the pistons 9, moving reciprocatingly, are contacted by means of rollers 10 with the working tracks 5 having a sinusoidal profile, 11 two-arm lever of the pendulum mechanism. The distance between the lower and upper points of the sinusoid corresponds to the stroke of the pistons of the cylinders.

 The engine operates as follows. The engine cylinders are closed by caps, in which valves are located for the intake of the fuel mixture and the release of exhaust gases. Each pair of opposing cylinders located on the same axis operates in opposite cycles, and the rods of each two adjacent opposing cylinders are balanced by a pendulum mechanism using a two-shouldered lever 11. The rotation of the disk rotor is carried out by the pressure of the rod rollers on the sinusoidal track 5 of the disk. Thus, the rotation of the rotor disk is carried out simultaneously with a stroke of half of the pistons of the cylinders, the second half of the pistons receives movement from the rotor disk. The combustion of the working mixture occurs in a single annular torus chambers, taken out of the over-piston space of the cylinders. Each chamber is working for a quarter of cylinders synchronously working in one cycle.

 Compared with star-type four-stroke engines, the proposed engine layout will reduce the size of the engine while increasing power. The presence of common combustion chambers will significantly increase the compression ratio of the fuel mixture, which will increase engine power with the same dimensions and use different types of fuel.
