2. Description of the Related Art At present, there are many proposals for producing working outputs, many of which have succeeded in making profitable progress, but none of them is practically feasible. It turns out that. The profit-making products reached by the above proposals are all too large or too small, and have various disadvantages of their performance, cost and complexity of construction. Many engines suffer severely from exhaust emissions that do not meet the strict requirements for clean air required by the law enforcement authorities of many countries, such as the United States, and rely solely on electrical power due to clean air regulations. Tend to be engine oriented. This trend exists despite the inherent disadvantages when electric power units are used, especially for transportation purposes.

In addition, many engines are based on Otto engines and, even in the past, have proven to be satisfactory power plants, but in terms of emitting sufficiently clean exhaust gas, and from the piston to the crankshaft. Efficient power transmission is challenging and suffers from various disadvantages.

[0005] In the case of superchargers for automotive engines, they are generally large and inefficient. Roots type pumps used as superchargers require 2.5 liter cylinders to convert 1 liter of air.

DETAILED DESCRIPTION OF THE INVENTION The present invention will first be described with particular reference to that utilized in a two-stroke rotary engine. However, as previously mentioned, this is exemplary, and the present invention may be applied to devices that perform other tasks, such as pumps, compressors, etc., with various modifications and adaptations as appropriate to the particular purpose. Obviously, it can be easily realized by those skilled in the art. A preferred embodiment for use as a pump or compressor is described in FIGS.

Referring to the accompanying drawings, FIGS. 1 to 15, and first of all, particularly in FIGS. 1, 2 and 3, the engine generally referred to by arrow 50 has a main housing 5 and an end housing 27. . The spindle 1 extends through the main housing 5 between the ends 2 of the spindle and the bearings 6 of the spindle.
It is supported by. In the present embodiment, a pair of rotor pistons 3 (one or more rotor pistons 3 are used in other embodiments) are connected to respective rotor shafts 4 completely opposite to the main shaft 1. And is supported by bearings 7. Seals 8 and 9 are each spindle 1
And provided on the rotor shaft 4. The main shaft 1 has a gear 10
This gear 10 is connected to a rotor shaft gear 11 via a timing spur gear 12 in the present embodiment. Gear cover 1 provided with gear cover seal 15
4 is positioned and fixed by a gear cover stud 13. The gear lubrication is such that oil is provided through an oil inlet 16 and then drained out of an oil outlet pipe 17,
Then it is filtered and returned. The oil lubricates the main bearing at 18 and lubricates the gears at 19 with a pipe 20. The pipe 20 provided for this lubrication is directed to an oil separation chamber 21 and the oil separation hole 2 of the rotor.
3 is used to lubricate the rotor bearing at 22. The separation gas holes 24 of the rotor allow gas and any oil passing through the separation holes 23 and the seal 9 to collect and escape. The oil collecting groove 25 is used for oil return 2
6 to provide an oil pan that is collected.

Particularly, in the present embodiment, the engine 50
Is the suction port 28 located adjacent to the outlet port 29
have. Opening 30 provides a gas bypass outlet through end housing 27.

Therefore, the main shaft 1 of the present embodiment has a pair of opposed radial cutouts or recesses therein for accommodating the respective rotor pistons 3, and the rotor pistons 3 have It can rotate with the main shaft 1 with a predetermined clearance, but the main shaft 1 and the rotor piston 3 all operate in a defined chamber in the main housing 5.

The spindle 1 has an end 2 of the spindle supported by a bearing 6 in an end housing 27, which is lubricated and cooled by lubrication grooves 18.

The rotor piston 3 is supported for rotation by a piston shaft 4, which is provided with a bearing 7 and supported by the end 2 of the main shaft.

The bearing 7 of the rotor piston is lubricated and cooled by oil. This oil is sent through a lubrication pipe 20 by centrifugal action, turns around in a centrifugal separation chamber 21, and rotates in a rotor separation hole 23. Pass through.
The seal 9 is made of ceramic or other material and has a separation hole 23 for oil flow to form a chamber.
The oil can be controlled so that it is centrifuged out of the chamber, but in this chamber any oil leaching blown with gas into the housing 5 will be separated gas holes 24

All oil is collected in an oil collecting groove 25 or an oil pan, collected in an oil return 26, drawn out to an oil suction pipe 17 for sucking up oil, and enters a gear box through an oil inlet 16.

The suction of the engine causes the vacuum to return to the oil 26
You can run the oil through the oil reservoir,
If necessary, another vacuum pump can be provided.

The engine 50 is provided with a spark plug 43 and a fuel injector 44. Of course, it is also possible to use a plurality of spark plugs and fuel injectors as another embodiment. In the present embodiment, engine 50 is liquid-cooled through cooling duct 46.

The engine 50 of the present embodiment preferably operates as a two-stroke engine with an open piston that fires twice rather than once for each revolution of the cylinder. As an alternative to this engine, if required, the same number of ignitions as each cylinder can be performed. In particular, as will be understood from the following points, the rotation for intake and exhaust is limited because the engine 50 rotates with positive intake and exhaust gas is swept out of the engine 50 by the rotor piston 3. It is unnecessary.

Most importantly, the present invention provides for a non-reciprocating engine 50 as understood by those skilled in the art, wherein the main shaft 1 is a conventional crankshaft. What is considered as an Otto engine that has been replaced and the usual connecting rods and cylinders have been removed. The main shaft 1 of the engine 50 extends over the entire length of the engine. However, it is preferable that the main shaft 1 be driven or driven from any one of the ends. In addition, as is evident from the brief description of the lubrication of the engine 50 in the preferred embodiment, it is a substantially oilless engine that does not require the rotor piston 3 to contact the main shaft 1 or the inner surface of the housing 5. Does not operate with a predetermined clearance, but rather provides a more efficient seal between the components by flowing the fluid through the engine. The clearance here is properly maintained by appropriate cooling of the engine 50, such as liquid cooling through the cooling duct 46 of the present embodiment.

The engine 50 of the present invention avoids any reciprocating motion and minimizes mechanical losses. In addition, in the preferred embodiment, no piston ring is required for the rotor piston 3 and friction losses are minimized.

Further, as will be understood from the following points in particular, since two ignition strokes of each cylinder are performed during each revolution, in this embodiment, the ignition is performed by 21 ignition strokes.
Given that a 0 ° rotation is achieved before exhaust, the engine of the illustrated embodiment requires 42 ° during each rotation from ignition.
A power of 0 ° can be exhibited.

The engine 50 is capable of receiving cylinder pressure while maintaining a perpendicular position to the main axis of the main shaft 1 during most of the work or explosion stroke. It will also be preferred by traders. In this regard, if the angle from the top of each rotor piston 3 which is back-to-back with the central axis is going to disappear, the rotor piston 3 becomes uncovered or exposed on the side surface of the rotor piston 3 and the pressure is increased by mechanical pressure. Maintains the preferred angle for converting to work and allows to accept pressure.

In FIGS. 4 to 15, the shaded areas in the figures are as follows:
It is intended to show very diagrammatically the state of charge of the air, fuel / air or exhaust gas resulting from the engine cycle.

In FIG. 4, a pair of rotor pistons 3 are mounted on each rotor shaft 4 around the main shaft 1 and
And the rotor piston 3 is shown to be rotatable in the main housing 5 very schematically. The rotor piston 3 is provided with a concave portion or a fan-shaped notch 51, 52 on the opposite side of the rotor piston 3. Each of the rotor pistons 3 maintains its position horizontally, and is supported by gears so that recesses or chambers 55 are provided on both sides of the main shaft 1 and the inner surface of the housing 5 and engage with a predetermined clearance. Have been.

In FIG. 4, at the beginning of the cycle of the engine 50, an air charge 31 is defined by a chamber 51 defined by the recess 51 of the bottom rotor piston 3 and the inner surface of the main housing 5, as indicated by the shadow. Suction port 28
Inhaled through. In the vicinity of the suction port 28 or between the suction port 28 and the exhaust port 29 there is a projection 54 on the wall of the main housing 5 which helps to define the chamber in which the air charge 31 is sucked, It serves to provide a demarcation point between the intake and exhaust of the cycle. In FIG. 5, the air charge 32, which is again shaded, is generated as the main shaft 1 rotates.
As the volume increases, in this case through the 90 ° position and the rotor piston 3 moves through the cylinder 47,
Inhaled charge 32 provides a seal behind rotor piston 3.

In FIG. 6, when the rotor piston 3 moves so as to approach the top of the housing 5, the rotor piston 3 together with the main shaft 1 creates a fresh air pocket 33. This air pocket 33 is, as shown in FIG.
When the fuel injector 44 performs the fuel injection 35, it is closed off from the engine cylinder 47 so that the remainder of the inhaled air charge remains. In this case, another protrusion 53 is shown on the inner wall of the housing 5 adjacent to the ignition plug 43 on the top of the housing 5. This protrusion 53
Defines a transition between the intake and exhaust sides of the engine.

In FIG. 8, a fresh air charge 33 is transferred to the exhaust side of the engine 50 and a fuel / air charge 36 is charged in front of the other rotor piston 3.
The state where the image is compressed so as to be pressed is shown. In FIG. 9, the fuel / air charge 37 is further compressed, while the fresh air charge 33 continues to be moved in front of the other rotor piston 3. FIG. 10 shows that a fresh air charge 33 is created by the upper rotor piston 3 while the compressed fuel / air charge is ignited by the spark plug 43.
As shown in FIG. 10, the ignition occurs in the original fresh air pocket 33 and is discharged through the outlet port 29 at the same time. Therefore, it is preferred that the engine 50 achieves the transfer of fresh air between the intake side and the exhaust side of the engine, thereby allowing a contribution by the fresh air discharged. This will reduce undesired constituents and associated proportions in the exhaust emissions.

Also, fresh air in contact with carbon monoxide and hydrocarbons in the exhaust gas will cause oxidation and significantly reduce unwanted pollutants.

In FIG. 11, the ignited charge 39 is
It is shown expanding along with the second fresh air charge 33 and moving through the right hand cylinder space 47. The purpose of the preferred combustion chamber design is to create a state where the air and fuel are completely mixed in the cylinder, when the combustion of the charge is completed in the shortest time,
The goal is to create high turbulence conditions so as to burn as completely as possible. The onset of turbulence is after the inlet port is completely closed, at the beginning of the compression process, and pockets of compressed exhaust gas break the viscosity and speed up heat transfer and fuel mix. It begins when a vortex that acts to cause an up-like interaction exits into the suction charge being created. FIG.
As the compression continues and reaches the ignition point, the flame front is broken by the protrusion 53, which passes through the combustion chamber during the combustion process. This increases the speed of the flame front travel which prevents turbulence and overheating of the end mixture. It is preferred that a fresh air charge 33 be present at all stages and assist in cooling the engine 50.

FIG. 12 shows the charge 40 as part of the explosion stroke, with the rotor piston 3 now in the 90 ° position, but then in the position shown in FIG. Form a pocket for exhaust gas 41, and the rotor piston 3 is moved to the intake side of the engine, as shown in FIG. As shown in FIG. 15, the remainder of the exhaust gas 42 is swept out by the rotor piston 3 through the exhaust port 29. The exhaust gas pocket 41 is moved to the intake side after the intake port 28 is closed so that it does not displace expensive intake air, and the charge 41 is returned to be included in the next ignition charge, and again desirable. It is preferable to contribute to reducing the emission of no exhaust gas. Further, the exhaust gas charge 41 can also distribute its thermal energy to the intake charge to improve the thermal efficiency of the engine 50. The three pollutants that are harmful when released into the atmosphere from the engine are CO, HC and NOx. When a chemically correct mixture is drawn into the combustion chamber, the carbon monoxide and hydrocarbon products produced by the combustion are significantly reduced, while the annoying nitrogen oxides are increased. About 20: 1
Leaning the air-fuel mixture reduces the generation of NOx but makes combustion unstable. By recycling the exhaust gas returned through the engine, the normal composition value is
CO and HC reductions can be maintained while reducing NOx emissions.

Recycling exhaust gas through the engine 50 is similar for most other engines,
While setting the throttle wide open, it will not replace all intake charges and the recycled exhaust gas will always be proportional to the throttle set. Testing has shown that 15% or more recycling of exhaust gas can reduce NOx to 88%.

In the above-described embodiment, a pair of rotor pistons 3 is shown. However, in various embodiments which can be expected by the present applicant, one or more rotor pistons 3 can be used. Think.

Referring to FIGS. 16-20, another embodiment of the present invention operates as a pump or compressor and is particularly suited for use as a supercharger for an engine.

As is well known, superchargers are used in various types of engines to provide a charge of air or fuel at a pressure above atmospheric pressure.

In the presently preferred type of turbocharger, a cylinder of approximately 2.5 times the volume to be replaced is required to supply. In contrast, the present invention has a smaller volume of cylinders or chambers than would be displaced per revolution, and in a preferred embodiment is at least three times greater than a conventional pump or turbocharger of the same size. More than twice the amount of air or fluid can be replaced. This means, of course, that the pump or compressor of the present invention can be of substantially smaller size, thus saving space.
In particular, it can be provided as having an advanced advantage for such things as an automobile engine room. For example, it is contemplated that the turbocharger according to the present invention may be smaller than a typical motor vehicle alternator.

First, FIG. 16 of the accompanying drawings shows one embodiment of the present invention.
A pump or compressor according to one embodiment is shown very diagrammatically, in which the main shaft 100 has a single housing 150.
, And a pair of rotor pistons 103 are mounted on respective rotor shafts 104. Each rotor piston 103 is provided in a respective opposed radial cutout or recess 155 formed in the main shaft 100 so that, when the main shaft 100 rotates, the surface of the recess 155 has a suitable practical clearance. It is supported in a substantially horizontal position in engagement with both surfaces of the housing 150.

FIG. 16 schematically shows the position of the rotor piston 103 with respect to the main shaft 100 for a half rotation of the main shaft 100. This figure is described as continuing from left to right and top to bottom in FIG. As each rotor piston 103 moves relative to the main shaft 100 from the initial position shown in the top left view, the fluid on each side of the housing 150 is drawn through one or more suction ports 160. Is swept out before the preceding rotor piston 103 side and is exhausted through one or more exhaust ports 161. Full rotation of the main shaft 100 results in being swept by each rotor piston 103 on both sides of the housing 150.
Thus, the pump or compressor discharges its capacity in half the rotation and discharges twice the capacity in one rotation.

Referring to FIG. 17, a particular embodiment of the present invention is shown schematically in an exploded view, wherein the rotor piston 103 rotates with the main shaft 100 and within the housing 150. Is placed. One set of exhaust ports 161 is provided, and on the opposite side there is a suction port 160, and an outlet pipe 200 and an inlet pipe 201.

FIG. 18 shows a front and side cross-sectional view. This figure shows an inlet pipe 201 and an outlet pipe 2
00 and a back manifold 209 provided around the gear assembly 210.
And a rotor gear 211 connected to each rotor 103 and the main gear 212. Air seal is arrow 2
13 and is suitably provided in the area indicated generally.

In particular, as shown in FIGS. 19 and 20, a rotor gear 211 meshes with a rotating spur gear 214 and a fixed main gear 212. In this embodiment and the above-described embodiments, it will be understood that the gear connection between the rotor and the main shaft is not merely used as a drive mechanism for maintaining the position of the rotor. Therefore, this gear connection, as specifically shown in FIG.
It ensures that the rotor 103 remains fixed horizontally with respect to the housing 150 as the main shaft 100 is rotating. A main bearing 215 is provided for the rear shaft assembly 216, and a dedicated bearing, such as 217, is provided for the shaft that couples with other gears. In FIG. 19, the main bearing 215 is shown at a position displaced from the actual position, but is provided on the front shaft assembly 205 having the drive shaft 217.

The inlet and outlet ducts of the fluid flow path may be suitably provided, for example, to accommodate various types and sizes of engines. In particular, where the ducts and ports are needed for a particular type of engine, such as V6 or V8, then the housing 15
0 internal duct and front and back manifold 20
8, 209 ducts may be provided accordingly.

The meanings of the above description used as specific parts or finished products in the present invention include known equivalents, and such equivalents are included in the individual descriptions herein. I have.
