Description

The invention relates to a fuel rotary piston engine according to the preamble of claim 1.

Such rotary piston engines are used in several areas of mechanical engineering, in particular as fuel rotary engines in automotive engineering.

Fuel engines in the form of a gasoline engine or as a diesel engine convert energy stored in a fossil fuel into mechanical energy through combustion.

The predominantly used in practice fuel engines have a four-stroke cycle (clock 1, suction // cycle 2, compression and ignition // cycle 3, burning and expanding // cycle 4, pushing out).

Known are the fuel engines with a Hubkolbentriebwerk for the conversion of a linear movement of the piston by Pleuelmechanismus in a rotating movement of a working shaft. The four-stroke cycle lasts at 720 ° revolutions of the working shaft.

This design principle of power transmission is not effective because the torque arises as a multiplication of the variable from maximum to minimum gas pressure on pistons with the variable conversely from minimum to maximum rotary arm of the crank-connecting rod pair.

In the sixties of the last century, a fuel rotary engine was developed, which operates on a rotary piston principle and is known as Wankel engine.

This Wankel engine consists of a stator with a non-circular cross-section cavity and a triangular in cross-section and dreispitzigen rotary piston with three trochoidenformigen contours, both of which form a working space of the fuel engine between them. The engine of the engine is a gear with a planetary mechanism with a centrally arranged to the cavity working shaft. The movement of the rotary piston in the working space is controlled by these planetary gear.

The transmission of the pressure forces from the rotary piston to the working shaft. takes place through the planetary mechanism of the transmission in four-stroke cycle after 1080 ° rotation of the rotary piston.

This Wankel engine is distinguished from reciprocating engines by an extremely simple design, higher torsional moment, power density with low weight and space requirements, as well as by a smoother running.

A similar fuel rotary piston engine was characterized by the DE 103 61 618 A1 known. Another similar fuel rotation engine was the DE 103 08 831 B3 2004.09.09 known. This fuel rotary engine consists of a stator with a cross-sectionally oval working space and a cross-sectionally oval rotary piston with an oval-shaped outer contour. The planetary movement of these rotary pistons in the working space is controlled by an automatic change of the rotary axis, which attack and rotate a centrally arranged working shaft in change. The four-stroke cycle runs after 1440 ° rotation of the rotary piston.

Both these fuel rotary engine and Wankel engine have significant drawbacks, which caused mainly the engine with the planetary mechanism and the planetary motion of the rotary piston.

It is also very disadvantageous that the rounded pressure surface on the rotary piston is not oriented perpendicular to the circumferential direction of the rotary pistons, so that only components of the forces developing from the gas pressure act in the direction of rotation of the rotary piston, while the other force components are absorbed by the bearing of the working shaft. Because it requires a mass balance against imbalances, much energy is lost, which deteriorates the efficiency.

A rotary piston machine with ring cylinders and in it on centrically arranged axis rotating piston, with rotary valves as shut-off parts, which are used in stationary working walls and divide the cylinder chamber, was through the WO 1996 022 453 known. A disadvantage of this machine is a complicated implementation of the propellant gases and fuel gases through diversion channels. In addition, it is inevitable a blowing of air-fuel mixture in exhaust gases.

Still a rotary engine from a housing, chambers with sliders, side walls and an in it centrally arranged axis rotating piston was through the DE 42 25 300 A1 known.

A disadvantage of this engine is leaking contact the gate valve tip with rotating piston and also a complicated implementation of the propellant gases and fuel gases through bypass ducts.

From patent application DE 2005 038 302.5-15 with additional registrations DE 10 2006 001 158.9 DE 10 2006 014 425 A1 is known a fuel rotary piston engine.

This fuel rotary piston engine consists of a stator which forms a closed cylindrical cavity from shell segments, valve segments with combustion chambers and sprung end plates, and a rotary piston connected to an output shaft, which is coaxially and non-rotatably connected to the output shaft and coaxially inserted into the cylindrical cavity of the stator ; form the two working spaces, which are separated by the top of the rotary piston, thereby dividing two controllable and alternately engaging in the workspaces isolating slide in one with the rotation of the rotary piston magnifying and a decreasing working chamber, and via a remote control unit switchable inlet channels with a Supply means for a fuel-air mixture and via the remote control unit switchable outlet channels with a disposal means for the spent fuel-air mixture is connected.

The rotary piston of this motor has in axial length an outer contour of two with a radius Rmin and other radius Rmin arcuate and with the circumferential angle of the rotary piston in the direction of rotation not changing outer contour parts, obliquely arranged in the direction of rotation axis connecting contour parts, the outer contour parts together and radially arranged outer contour parts , which combines arcuate outer contour parts from the other side of the outer contour of the rotary piston. An arcuate outer contour of the same cylindrical cavity has the stator radius Rmax and the second arcuate outer contour portion has the radius Rmin smaller than radial outer contour pitch; the arcuate outer contour parts abut each other and form a tip on the rotary piston in this area.

With this invention, important drawbacks have been solved the fuel rotary piston engines with the planetary movement of the piston and disadvantages known rotary piston engines.

A disadvantage remained but a gas-pressure-tight line contact between the slide and obliquely arranged in the direction of the axis of rotation connecting contour parts of the rotary piston to which from the gas pressure evolving forces do not act in the direction of rotation of the rotary piston, but in the opposite direction. Therefore, the efficiency deteriorates.

With the invention according to patent application DE 10 2009 029 950.5 These disadvantages were also known rotary piston engines solved.

In this engine there are rotary pistons ( 2 ) of cylindrical mirrored arranged pair of ring segments ( 2:01 . 2:01 ' and 2:02 . 2:02 ' ), which Außenkonturradirussen have two different sizes and by gas-tight contact side surfaces and outer contours of the ring segments ( 2:01 . 2:01 ' ) and ( 2:02 . 2:02 ' ) with inner surface cylindrical cavity ( 4 ) the stator ( 1 ) Work Rooms ( 11 . 11 ' ), which are larger than fireboxes ( 16 . 16 ' ), while outer radius Rmax ring segments ( 2a . 2a ' ) is equal to the inner radius of the cylindrical hollow body, the stator ( 1 ) and outer radius Rmin ring segments ( 2 B . 2 B' ) is smaller than the inner radius of the cavity the stator ( 1 ) and the outer contours of the wheel segments (( 2:01 With 2:01 ' ) ...) rotary piston ( 2 ) with outer contours of the ring segments (( 2:02 With 2:02 ' ) on both sides with radial outer contours ( 29 . 30 and 29 ' . 30 ' ) are connected and serve as a printing surface in four-stroke work process.

The rotary piston ( 2 ) consists of ring segments ( 2:01 . 2.01 '; 2:02 . 202 ' ) whose inner contours with the output shaft ( 3 ) by three-dimensional in the form of screw blade bent wheel spokes ( 26 ) are connected.

• – es besteht eine Gefahr der Blockierung des Motors durch eine Kollision zwischen Kolben und den Trennschieber, insbesondere bei eine Panne in Automatik der Fernsteuerungseinheit;
• – die Durchlässigkeit den Einlass- und Auslass-Tellerventile ist nicht genügend groß für Gasstromgroßen des Motors;
• – die Steuerung von Einlass- und Auslassventile ist mit der Bewegung von Trennschieber nur durch Automatik der Fernsteuerungseinheit verbunden;
• – bei schlagartigem Kontakt den Trennschieberspitzen mit Rotoroberfläche ist eine Abplatzung beiden Flächen unvermeidlich.

But also this invention have the following disadvantages:

• There is a risk of the engine being blocked by a collision between the piston and the separating slide, in particular in the event of a breakdown in the automatic control unit of the remote control unit;
• The permeability of the inlet and outlet poppet valves is not sufficiently great for gas flow quantities of the engine;
• The control of intake and exhaust valves is linked to the movement of the isolating gate only by the automatic of the remote control unit;
• - In case of sudden contact the separator slide tips with rotor surface chipping both surfaces is inevitable.

Because of these disadvantages, the invention according to patent application DE 10 2009 029 950.5 difficult to realize.

It is therefore the technical task to develop a realizable fuel rotary piston engine.

This object is solved by the characterizing features of claim 1. Further embodiment possibilities emerge from the dependent claims 2 to 8.

To block the engine by collision of the rotary piston tip ring segment ( 2:01 2:01 ' ) and isolating slide ( 12 . 13 ), the gate valves ( 12 . 13 ) from the remote control unit ( 23 ) quickly and in milliseconds used quickly and withdrawn.

It should also include inlet / outlet slots ( 1.16 ) of the combustion chamber ( 16 ) closed in time and opened after fueling.

In the new fuel rotary piston engine these operations are by the application of the calculation results the measure of distances (a, b, c, d) in valve segment ( 6 ) between axles exhaust and intake valves ( 25 . 28 ) and isolating slide ( 12 . 13 ) to axis of the combustion chamber and the measure the rotary piston tip ring segment ( 2:01 ) He feels. The remote control unit ( 23 ) work undisturbed.

From the remote control unit ( 23 ) of the motor are for the sliding movements of the slide ( 12 . 13 ), as is customary for such purpose, as the execution mechanisms the electric tension and compression magnets ( 2.12 ; 2.13 ) with rod-shaped anchors ( 3.12 ; 3.13 ), which at armature change of the armature ( 3.12 . 3.13 ) and the separating slide ( 12 . 13 ) move in the pulling direction away from the motor axis or in the pressure direction to the motor axis.

In the new fuel rotary piston engine, the rod anchors ( 3.12 . 3.13 ) with a suspension ( 4.12 . 4.13 ), which in the event of a power failure in the remote control unit ( 23 ) the bar anchors ( 3.12 . 3.13 ) moved in the pulling direction and separating slide ( 12 . 13 ) from workspaces ( 11 . 11 ' ) of the engine immediately pulls out.

This is the blocking of the engine by collision of the wheel segment ( 2:01 2:01 ' ) and isolating slide ( 12 . 13 ) avoided.

The new fuel rotary piston engine has cylindrical pressure-tight exhaust and intake valves ( 25 . 28 ) with inlet / outlet openings ( 25.01 . 28.01 ), which have the cross-sectional area of 1/3 to 2/3 of the working space of the engine, while the closure and the opening of the exhaust and intake valves ( 25 . 28 ) is carried out by the turning movement with the aid of remote-controlled known magnetic mounts or by connecting rod mechanisms ( 31 ).

Each connecting-rod mechanism is equipped with a long connecting rod ( 31.01 ) on the sliding anchors of the dividers ( 12 . 13 ) and with other, short, ( 31.02 ) - to cylindrical exhaust or inlet valves ( 25 . 28 ).

The new fuel rotation motor has the outer contours of the ring segments ( 2:02 . 2:02 ' ) the rotary piston ( 2 ) with reductions ( 2021 ) of the surface in front of ring segments ( 2:01 . 2:01 ' ), which by sliding contours ( 2022 ) with further parts outer contours ( 2:01 . 2:01 ' ), reductions ( 2021 ) Peripheral angle g, which is greater than calculated according to the equation (G), and the sliding path the separating slide ( 12 . 12 ' ) with the aid of an adjustment disk ( 4.12 ) to bar anchors ( 3.12 ) the electric tension and pressure magnets ( 2.12 ) are so delimited that separator slide tips the surface of the subsidence ( 2021 ) do not reach.

The fuel rotation engine has the rotary piston ( 2 ), which consists of cylindrical mirrored pair of ring segments ( 2:01 . 2:01 ' and 2:02 . 2:02 ), the Außenkonturradirussen have two different sizes and by gas-tight contact side surfaces and outer contours of the ring segments ( 2:01 . 2:01 ' ) and ( 2:02 . 2:02 ' ) with inner surface cylindrical cavity ( 4 ) the stator ( 1 ) Work Rooms ( 11 . 11 ' ), while outer radius Rmax ring segments ( 2a . 2a ' ) is equal to the inner radius of the cylindrical hollow body, the stator ( 1 ) and outer radius Rmin ring segments ( 2 B . 2 B'' ) is smaller than the inner radius of the cavity the stator ( 1 ).

The outer contours of the ring segments (( 2:01 With 2:01 ' ) are with outer contours the ring segments (( 2:02 With 2:02 ' ) on both sides with radial outer contours ( 29 . 30 and 29 ' . 30 ' ), which serve as a printing surface in the four-stroke work process.

During the rotary movement of the rotary piston ( 2 ) must be the ring segments ( 2:01 . 2:01 ' ) with its outer contour ( 2011 ) exactly after four-stroke work process the inlet / outlet slots ( 1.16 ) the combustion chambers ( 16 . 16 ' ) without collision with separating slide ( 12 . 13 Close and open.

To fulfill this function, the new fuel rotary engine has the rotary piston ( 2 ) the ring segments ( 2:01 . 2:01 ' ), which of the outer contour ( 2011 ) with the peripheral angle e calculated according to equation (E).

To block the engine by collision of the ring segment ( 2:01 2:01 ' ) and isolating slide ( 12 . 13 ) continued to occupy the ring segments ( 2:01 2:01 ' ) wedge-shaped sliding plates which are in the direction of rotation ( 2012 ) and the separating slide ( 12 . 13 ) have sliding slots ( 6.12 . 6.13 ), which the inclination and the width of the sliding plates ( 2012 ) correspond.

The invention will be explained in more detail with reference to an embodiment. In this engine a complete 2 × 180 ° four-stroke cycle is 360 °.

The new fuel-fired engine will be described below with a two-pointed rotary piston ( 2 ), as well as in the 1 and 2 and in a representation of the successive movements 3 and 4 is shown.

To show:

1 the fuel rotation engine in the starting position in cross section,

2 the valve segment ( 6 ) of the motor in cross section;

3 the fuel rotation motor in the position 315 ° to 390 ° rotation of the rotary piston ( 2 );

4 the fuel rotation motor in the position 495 ° to 560 ° rotation of the rotary piston ( 2 );

The new fuel rotation engine is made according to 1 and 2 essentially from a stator ( 1 ), a rotary flask ( 2 ) and a working wave ( 3 ). The stator ( 1 ) is made of several parts and pressure-tight and consists of symmetrically arranged shell segments ( 5 . 5 ' ) and valve segments ( 6 . 6 ' ), which after assembly have a cylindrical cavity ( 4 ) and face plates ( 7 . 8th ) the cylindrical cavity ( 4 ) close on both sides.

The shell segments ( 5 . 5 ' ) are intended for the cooling of the fuel rotation engine. In the shell segments ( 5 . 5 ' ) are conventional cooling elements ( 10 ) in the form of cooling channels for corresponding cooling liquid.

Face plates ( 7 . 8th ) and rotary flasks ( 2 ) are cooled with the air blown in holraum or the cooling liquid.

The valve segments ( 6 . 6 ' ) are for the arrangement of the functional elements of the engine: symmetrically arranged separating slide ( 12 . 12 ' and 13 . 13 ' ), Combustion chambers ( 16 . 16 ' ) with inlet / outlet slots ( 1.16 ), Inlet channels ( 24 . 24 ' ) and outlet channels ( 27 . 27 ' ) with controllable valves ( 25 . 25 ' . 28 . 28 ' ) designed.

The cavity ( 4 ) the stator ( 1 ) is cylindrical and the rotary piston ( 2 ) is coaxial and non-rotatable with the output shaft ( 3 ) and coaxial with the cylindrical cavity ( 4 ) the stator ( 1 ), whereby rotary pistons ( 2 ) of cylindrical mirrored arranged pair of ring segments ( 2:01 . 2:01 ' and 2:02 . 2:02 ' ), the outer contour wheels have two different sizes, while outer radius Rmax ring segments ( 2:01 . 2:01 ' ) is equal to the inner radius of the cylindrical hollow body, the stator ( 1 ) and outer radius Rmin ring segments ( 2:02 . 2:02 ' ) is smaller than the inner radius of the cavity the stator ( 1 ).

The rotary piston ( 2 ) has in ring segments ( 2:02 . 2:02 ' ) in outer contours in front of ring segments ( 2:01 . 2:01 ' ) Subsidence of the surface ( 2021 ), which is greater than the thickness of the separating slide ( 12 . 12 ' ) and by sliding contours ( 2022 ) with further parts outer contours ( 2:01 . 2:01 ' ) are connected.

The outer contours ( 2011 ) the ring segments ( 2:01 . 2:01 ' ) have circumferential angles e calculated according to the equation (E) and are provided with outer contours of the ring segments ( 2:02 . 2:02 ' ) on both sides with radial outer contours ( 29 . 30 ; 29 ' 30 ' ), which serve as a printing surface in the four-stroke work process.

By gas-tight contact the ring segments ( 2:01 . 2:01 ' ) and ( 2:02 . 2:02 ' ) with cylindrical hollow body the stator ( 1 ) are workspaces ( 11 . 11 ' ), the largest being as fireboxes ( 16 . 16 ' ). Here is the workspace ( 11 ) by the outer contours of the ring segments ( 2:01 . 2:01 ' and 2:02 . 202 ' ) and the working space ( 11 ' ) bounded by the outer contours of the ring segments ( 2:01 ' . 2:01 and 2:02 . 2:02 ' )

During the rotary movement of the rotary piston ( 2 ) open and open ( 3 . 4 ) the ring segments ( 2:01 . 2:01 ' ) without collision with separating slide ( 12 . 13 ) with its outer contour ( 2011 ), which became the peripheral angle e calculated by the equation (E), exactly after the four-stroke work process, the in / exhaust slots (FIG. 1.16 ) the combustion chambers ( 16 . 16 ' ). The blocking of the motor by collision of the ring segment ( 2:01 2:01 ' ) and isolating slide ( 12 . 13 ) avoids further to the ring segments ( 2:01 2:01 ' ) wedge-shaped sliding plates which are in the direction of rotation ( 2012 ), on which wedges the separating slides ( 12 . 13 ) with a sliding slots ( 6.12 . 6.13 ), the inclination of the wedges and the width of the sliding plate ( 2012 ), from workspaces ( 11 . 11 ' ) is thrown.

In both valve segments ( 6 . 6 ' ) are housed the necessary for the four-stroke work process the fuel rotary piston engine facilities which via appropriate control lines ( 18 . 19 . 20 . 21 . 22 ) with a remote control unit ( 23 ) are connected. So there are in each valve segment ( 6 . 6 ' ) the stator ( 1 ) a combustion chamber ( 16 . 16 ' ), in the change of one of the two workspaces ( 11 . 11 ' ) serves as a compression or ignition chamber and with an inlet / outlet slots ( 1.16 ) at Holraum ( 4 ) the stator ( 1 ) is open.

In every combustion chamber ( 16 . 16 ' ) is a spark plug ( 17 . 17 ' ) and an injection nozzle ( 33 . 33 ' ) a high-pressure injection system ( 32.32 ' ), both from the remote control unit ( 23 ) are actuated.

In both valve segments ( 6 . 6 ' ) the stator ( 1 ) are still with the angular distance (a) of the combustion chamber axis separating slide ( 12 . 12 ' ), with the angular distance (b) of the combustion chamber axis separating slide ( 13 . 13 ' ), with the rotational angular distance (c) of combustion chamber axis intake valves ( 25 . 25 ' ) and with the rotational angular distance (d) of combustion chamber axis exhaust valves ( 28 . 28 ' ) arranged.

Turning angle distances (a, b, c, d) are determined according to the equations (A, B, C, D).

Each of these isolation valves ( 12 . 12 ' . 13 . 13 ' ) is radially aligned and has a slide path which is a difference between the maximum and minimum radius of the ring segments (FIG. 2:01 . 2:02 ) of the rotary piston ( 2 ) corresponds.

The separating slide ( 12 . 12 ' . 13 . 13 ' ) each from the remote control unit ( 23 ) according to running the motor with the sliding movements rod-shaped anchor ( 3.12 . 3.13 ) electric tension and pressure magnets ( 2.12 . 2.13 ) by changing the direction of current in the pulling direction away from the motor axis or in printing direction to motor axis drive shaft ( 3 ) move.

The rod anchors ( 3.12 . 3.13 ) electric tension and pressure magnets ( 2.12 . 2.13 ) are equipped with a suspension ( 5.12 . 5.13 ), which in case of power failure in the remote control unit ( 23 ) the bar anchors ( 3.12 . 3.13 ) moved in the pulling direction and separating slide ( 12 . 13 ) from workspaces ( 11 . 11 ' ) of the engine immediately pulls out.

This is the blocking of the engine by collision of the ring segment ( 2:01 2:01 ' ) and isolating slide ( 12 . 13 ) avoided.

With each operation, the isolation slides ( 12 . 13 ) in the direction of the motor axis at the speed about 150 m / sec. to surface of the ring segment ( 2:02 There is a risk of a sudden contact with the flattening of the tip of the slider and a Deformation of the surface of the ring segment ( 2:02 ) in contact point.

The following technical solution ( 2 ) avoids the abrupt contact separator slide tip with the rotor, thereby ensuring a gas-tight contact.

The outer contours of the ring segments ( 2:02 . 2:02 ' ) the rotary piston ( 2 ) have reductions ( 2021 ) of the surface in front of ring segments ( 2:01 . 2:01 ' ), which by sliding contours ( 2022 ) with further parts outer contours ( 2:01 . 2:01 ' ), reductions ( 2021 ) Peripheral angle g, which is greater than calculated according to the equation (G).

The sliding way the dividers ( 12 . 12 ' ) with the help of the adjustment discs ( 4.12 . 4.13 ) to bar anchors ( 3.12 . 3.13 ) the electric tension and pressure magnets ( 2.12 . 2.13 ) are so delimited that separator slide tips the surface of the subsidence ( 2021 ) on ring segments ( 2:02 . 2:02 ' ) in use moment ( 2 ) do not reach.

Upon further rotation of the rotary piston ( 2 ) slide separator tips on surface of the ring segments ( 2:02 . 2:02 ' ) by sliding contours ( 2022 ,) on outer contours ( 2:02 . 2:02 ' ) with R min, are thereby with the pressure of the electric tension and pressure magnets ( 2.12 . 2.13 ) and form a gas-tight contact with which the working space ( 11 ) on working chamber ( 14 . 15 ) has been divided.

In the working chambers ( 14 . 15 ) according to four-stroke cycle in alternation by cylindrical Enlass- ( 25 . 25 ' ) and exhaust valves ( 28 . 28 ' ) sucked air (clock 1,) and fuel lanes pushed out (clock 4).

Cylindrical Enlass ( 25 . 25 ' ) and exhaust valves ( 28 . 28 ' ) are in valve segment ( 6 ) of the stator ( 1 ) with rotational angular distances (c and d) of combustion chamber axis according to the equations (C and D).

The exhaust and intake valves ( 25 . 28 ) have inlet / outlet openings ( 25.01 . 28.01 ), which have the cross-sectional area of 1/3 to 2/3 of the cross-sectional area of the working space of the engine, while the closure and the opening of the exhaust and intake valves ( 25 . 28 ) is carried out by the turning movement with the help of remote-controlled known magnetic seats or by the connecting rod mechanisms ( 31 ).

Each connecting-rod mechanism is equipped with a long connecting rod ( 31.01 ) on the sliding anchors ( 3.12 . 3.13 ) the dividers ( 12 . 13 ) and with other, short, ( 31.02 ) - to cylindrical exhaust or inlet valves ( 25 . 28 ). ( 2 )

In this motor after 360 ° rotations of the rotary piston run the four-stroke duty cycle (clock 1, suction // cycle 2, compression and ignition // cycle 3, burning and expanding // cycle 4, pushing out) twice, it takes the operation - burning and expanding // bar 4 - also - 2 × 180 = 360 °.

At the 180 ° revolutions of the rotary pistons, the expansion pressure quickly lowers fuel gases from fuel stored in the combustion chamber and ignited. With modern high-pressure injection systems, it is possible after a finely controlled direct injection in pre-compressed air combustion chamber ( 16 ) at the end of the cycle ignite 2-fuel, and with a post-injection of the fuel or water in the combustion chamber or chamber where the clock runs 3-burning and expanding, keep the expansion pressure at a reasonable level.
