SK9208Y1 - Engine with rocking pistons - Google Patents

Abstract

The construction of the engine can be in a petrol or a diesel modification consisting of at least two opposing rocking pistons. The engine block (1) is formed in one piece in which two rocking pistons (2) with seals are slid on the central cylinders (10). On each of the shorter sides of the engine block (1) there are valves (5) of the intake and exhaust pipes and a spark plug (4) in the case of ignition modification. The rocking pistons (2) move in a semicircle. On one side moving against each other and on the other side away from each other. Their rotation center is around the central cylinders (10) of the engine block (1). To each side of the rocking piston (2) the cranks (7) are attached via a pin and needle bearings, which extend to a crankshaft with teeth (6) on which cranks (7) with a needle bearing are mounted on the pin. The crankshaft (6) of the engine (1) has a toothing which transmits torque to the cam gear (9) which drives the drive shaft (11) and at the same time drives the camshaft (3) of the intake and exhaust valves (5). The engine block (1) is closed by a sealing lid or a reducing lid when modifying the motor step arrangement to connect another identical part for greater engine power.

Description

Technical field

The technical solution concerns internal combustion engines, an engine with rocking pistons in the modification of a petrol or diesel engine. From the point of view of production, the technical solution falls into the field of engineering and from the point of view of use it falls into the field of land transport in particular.

Prior art

Various engine designs are known in the art. From a rotary engine to a conventional reciprocating diesel or spark ignition internal combustion engine. The construction of these motors is well known. The design of such motors contains a large number of moving parts, which reduces the power of the motor.

Therefore, there is a need to create a new power unit that provides a minimum number of power unit parts and a minimum weight. At the same time, it could be a drive unit, which should have greater efficiency, wider use and simpler construction than the prior art. The result of this effort is further described as an internal combustion engine in a modification of a petrol or diesel engine in the present utility model.

The essence of the technical solution

These shortcomings are eliminated by a four-stroke engine with a rectangular shape of the engine block. The shorter sides are in the shape of a semicircle, on which the valves of the intake and exhaust pipes and the ignition or diesel system according to this technical solution are located. Inside the engine block, two cylinders are located in the middle, which are connected by a wall that separates the working spaces of the engine. Rocking pistons are slid on the cylinders, which describe a semicircle when moving. In addition to the following parts, it consists of at least two rocking pistons. However, this does not exclude that no other identical part can be connected to this part and the engine cannot be used as a stepper with multiple rocking pistons. A crank is attached to each side of the piston and extends to the engine crankshaft. The engine shaft crank is equipped with a gear that transmits torque to a central gear that drives the camshafts and further transmits torque to the driven shaft.

Overview of figures in the drawings

The four-stroke engine with rocking pistons in the modification of a petrol or diesel engine according to the technical solution will be explained in more detail in specific implementations in the drawings, where fig. 1 shows a front view of an arrangement of engine parts. In FIG. 2 is a side view of the engine showing the shape of the engine block and the timing gear transmitting torque to the driven shaft. In FIG. 3 shows the movement of the rocking pistons and all moving parts.

Examples of embodiments

The individual embodiments of the motor according to the technical solution are presented for illustration and not as limitations of technical solutions. Those skilled in the art will find, or be able to ascertain using no more than routine experimentation, many equivalents to specific embodiments of a technical engine solution. Such equivalents will also fall within the scope of the following protection claims.

For those skilled in the art, the sizing of such an engine and the appropriate choice of its materials and construction arrangements cannot be a problem, so these features have not been addressed in detail.

The technical solution of the engine design in the modification of a petrol or diesel engine consists of at least two rocking pistons (2), the engine block (1) would be formed in one piece, in which two rocking pistons (2) would be slid on the central cylinders (10) with sealing. On each of the shorter sides of the engine block (1), the intake and exhaust manifold valves (5) and the spark plug (4) would be located during the spark ignition modification. The rocking pistons (2) would move in a semicircle, moving against each other on one side and away from each other on the other. Their center of rotation would be around the center cylinders (10) of the engine block (1). To each side of the rocking piston (2), cranks (7) would be attached via a pin and needle bearings, which would continue on a crankshaft with teeth (6), on which they would be fixed to the crank pin (7) with a needle bearing. The crankshaft (6) of the engine (1) has a gear that transmits torque to the cam gear (9), which would drive the driven shaft (11) and at the same time drive the camshaft (3) of the intake and exhaust valves (5).

SK 9208 Υ1 exhaust system. The engine block (1) would be closed with a sealing lid or a reducing lid when modifying the motor step arrangement to connect another identical part for greater engine power.

The function of a four-stroke engine with rocking pistons designed according to this technical solution results from the individual cycles. The idea of engine operation is shown in FIG. 3 and also the movement of the pistons of sides A and B shown.

Suction - side A, the pistons move away from each other, the propellant is sucked through the suction valve (during direct injection only air is sucked in and the propellant is injected through a nozzle located in the engine block.) Side B, at this moment the pistons move in direction to me. The exhaust valve is open. Exhaust gases from the work area are forced into the exhaust pipe.

Compression - side A, the pistons move towards each other. Both valves are closed. The sucked mixture reduces its volume, increases the pressure and temperature. Shortly before the maximum approach of the rocking pistons, the mixture is ignited by an electric spark plug. Side B, the pistons move away from each other, the propellant is sucked through the suction valve.

Expansion - side A, both valves are closed. The mixture of fuel ignited by an electric spark burns. The temperature and pressure of the generated gases will increase sharply in the working space. They expand and do work as the rocking pistons move away from each other. Side B, the pistons move towards each other. Both valves are closed. The absorbed mixture reduces its volume, increases its pressure and temperature. Just before the maximum approach of the rocking pistons, the mixture is ignited by an electric spark plug.

Exhaust - side A, pistons moving towards each other. The exhaust valve is open. Exhaust gases from the work area are forced into the exhaust pipe. Side B, both valves are closed. The mixture of fuel ignited by the electric spark of the candle will burn. The temperature and pressure of the generated gases will increase sharply in the working space. These expand and do the work as the rocking pistons move away from each other.

Industrial applicability

The four-stroke engine with rocking pistons in the modification of a petrol or diesel engine according to the technical solution finds application in the field of land transport in particular.
