Abstract

PURPOSE:To effectively use exhaust gas so as to increase the torque of an internal combustion engine by jetting exhaust gas to turbine blades and a turbine wheel from an exhaust hole which is opened by opposed pistons adapted to be guided and reciprocated in a curved guide, by way of a nozzle. CONSTITUTION:Opposed pistons 11, 12 disposed in a body 1 are rotated by a rotary shaft 24, and the piston 12 is guided and reciprocated in a curved groove 17 formed in a curved groove cylinder 16. When the piston 11 approaches its top dead center, an exhaust hole 10 is opened. Exhaust gas from the exhaust hole 10 is jetted onto turbine blades 21 of a turbine wheel 20 and turbine blades 8 of the body 1 by way of a nozzle 7 so as to rotate the turbine wheel 20 and the body 1. A torque from this turbine wheel 20 is transmitted to the body 1 by way of an internal gear 22, a small gear 19 and a large gear 9, and accordingly it is possible to increase the torque of the body 1. Thus, since the body 1 is rotated with the use of exhaust gas, it is possible to enhance the efficiency of energy.

Description

[Detailed Description of the Invention] "Industrial Application Field" This invention transmits the rotation of a screw that reciprocates while rotating to the engine body, extracts power directly from the rotating cylinder, and utilizes exhaust gas. The present invention relates to an internal combustion engine equipped with a turbine that rotates the main body.

"Prior Art" A conventional internal engine is configured to convert reciprocating motion of a piston into rotational motion of a power shaft via a crank mechanism.

Therefore, a large amount of energy is lost through the crank mechanism.

The present applicant invented a two-stroke internal combustion engine that does not require a crank mechanism, and previously filed a patent application for a "rotating reciprocating piston internal combustion engine" (Japanese Patent Laid-Open No. 58-98602). Furthermore, he made several improvements to the invention and filed several patent applications.

The gist of these inventions is as follows.

The main body has a combustion chamber formed between pistons housed facing each other, and a curved groove cylinder is rotatably fitted onto the main body and fixed thereto.

A piston pin protruding from the piston passes through a long groove extending in the longitudinal direction opposite to the main body, and is fitted into a curved groove recessed in the inner circumferential surface of the curved groove tube.

A curved groove is formed so that the main body 1 rotates once by the piston, which rotates once during two reciprocations.

Note that the main body is provided with a nozzle, and the rotational force of the main body is increased by injecting exhaust gas from the nozzle.

The "Rotating Reciprocating Piston Internal Combustion Engine" of JP-A-6-79821 has a group of exhaust holes in the engine body housing the pistons facing each other, and a turbine blade in the nozzle that communicates with the group of exhaust holes. In addition, turbine blades are also installed on the fixed curved groove tube, and the turbine is closed with an I-F.

"Problems to be Solved by the Invention" However, the purpose of the internal combustion engine equipped with the turbine is to obtain a high-speed rotation, high-output internal combustion engine by arranging turbine blades in multiple stages. The drawback was that it was not possible to obtain a compact configuration suitable for installation in automobiles and the like.

"Means for Solving the Problems" Therefore, an object of the present invention is to provide a compact internal combustion engine, and the gist thereof is as follows.

That is, a nozzle that discharges exhaust gas into the main body, a turbine blade that rotates the main body by the exhaust air from the nozzle, and a rotary vane wheel that is rotatably supported by a curved groove tube and has turbine blades and is rotated by the exhaust air from the nozzle. , and a gear device for transmitting the rotation of the rotary impeller to the main body.

``Operation'' The exhaust gas from the nozzle collides with the turbine blades of the main body, causing the main body to rotate. The exhaust gas from the nozzle also collides with the turbine blades of the rotary wheel, causing the rotary wheel to rotate.

The rotary impeller is rotatably supported by a fixed curved tube, and its rotation is transmitted to the main body via a gear mechanism.

Therefore, in addition to the rotation due to the reciprocating motion of the piston, the main body rotates due to rotation by the turbine blades of the main body using exhaust gas and rotation by the rotor wheel.

``Effects'' Since there is no crank mechanism, there is no loss of energy due to crank movement, and the exhaust gas is used as an energy source, which improves thermal efficiency.

Moreover, since there is no crank mechanism, it can be formed compactly.

In particular, since the rotation of the rotary blade wheel is transmitted to the main body via a gear mechanism, the rotation speed of the turbine blades is added to the rotation speed of the main body, so it can be made more compact and can be installed in automobiles and the like.

``Example'' The present invention will be described in detail below based on the illustrated example.

As shown in Figures 1 to 3, reference numeral 1 denotes an engine body with a cylindrical interior, and the central part forms a combustion chamber 2. long groove 3

A large number of air supply holes 4 open to the combustion chamber 2 on one side of the combustion chamber 2 (the left side in FIGS. 1 and 2) and communicate with each other, and communicate with a group of 4 air supply holes and open to the outside of the combustion chamber 2. It has an inlet 5a (see FIG. 4) and a plurality of spark plugs 6 arranged in the combustion chamber 2.

In addition, on the other side of the combustion chamber 2 (on the right side in the drawing), there is a combustion chamber 2.

11 is a pair of left and right pistons, and the combustion chamber 2 is formed between these pistons 11.

The piston 11 passes through the long groove 3 from the piston 11,
Each has a piston pin 12 that projects in the diametrical direction. Reference numeral 13 is a stopper fitting that also serves as a guide. Furthermore, rolling wheels 4 are rotatably attached to both ends of each piston pin 12.

Reference numeral 16 denotes a pair of fixed left and right curved groove tubes, which are fitted onto the outside of the main body 1 so that the main body 1 can rotate freely. The rolling ring 14 of the piston pin 12 is fitted into the curved groove 17 formed in the inner circumferential surface of the piston pin 12 so as to be freely movable. This curved groove 17
is formed so that when the piston 11 makes two reciprocations, the piston pin 12 rotates once, and therefore the main body 1 also rotates.

Note that 18 is an intake port, which is connected to an intake manifold (not shown) (see FIG. 2).

Reference numeral 19 indicates two small gears, upper and lower, and the inner small gear 19a is rotatably attached to the curved groove tube 16 so as to mesh with the large gear 8 (see FIG. 5).

Reference numeral 20 denotes a rotary impeller, and its Tahin H2 group is rotatably attached to the curved groove tube 16 on the inner circumferential side of the turbine blade 8 of the cylinder 1 so as to fit into the nozzle 7. It has an internal gear 22 that meshes with the small gear 19b on the outside of the gear 19 (see FIG. 6). Of course, the turbine blades 8 of the main body 1 and the turbine j421 of the rotary impeller 20 can be configured in multiple stages.

Reference numeral 23 denotes an inner lid having a rotating shaft 24, which is fixed to the left and right outer ends of the cylinder l, and is provided with a through hole 25 communicating with the intake port 18. The right side of the rotating shaft 24 is used as a power shaft, and the left side is connected to a generator.

Reference numeral 26 denotes an outer cover, which is fixed to the left and right outer ends of the curved groove tube 16, respectively, and seals the intake chamber 27a formed by the curved groove tube 16 and the inner cover 23.

28 is inside the left and right! It is a partition wall fixed to the inner peripheral surface of 23,
A through hole 29 is provided therethrough. 30 is a valve that opens and closes the through hole 29; An intake chamber 2 is provided between the partition wall 28 and the main body 1.
7b is formed.

Reference numeral 31 denotes a ring-shaped exhaust box, which discharges the exhaust gas from the nozzle 7 through an exhaust pipe (not shown), and is fixed to the curved groove pipe 16.

32 is connected to the ignition device not shown with the ignition fitting, and the mounting fitting 3
3 to the exhaust box 31 and supplies power to the spark plug 6.

Here, this internal combustion engine is configured as follows.

When the piston 11 approaches the bottom dead center due to the explosion of the air-fuel mixture, the 10 groups of exhaust holes open first, and the 4 groups of exhaust holes open a little later. Prior to the opening of the 4 groups of exhaust holes, the air supply port 15 of the piston 11 is opened with the introduction of the main body 1 [Zt 5 a, 51] and iJ! Clean the inside.

When the piston 11 moves from the bottom dead center to the top dead center, the four stages of air supply holes are closed. Next, the air supply port 15 and the introduction port 5a
, 51) are blocked, and zu1. Ten groups of stomata are occluded.

When the piston 11 approaches top dead center and the mixture is compressed, the mixture is ignited by the ignition plug 6, explodes, and the piston 11
If so, move to the bottom dead center side.

Although not shown, it goes without saying that various types of seals are appropriately selected and attached to parts that require airtightness, and pole (roller) bear links, air bearings, magnetic hair rings, etc. are appropriately selected and attached to rotating parts.

From the above configuration, when the piston 1 first moves from near the bottom dead center shown in Figure 1 to the top dead center side, the valve 30 opens the through hole 29 as shown in Figure 2, and the air-fuel mixture flows into the intake port. 18, the intake chamber 27, and the through holes 25 and 29, and are drawn into the piston 11. When the piston] 1 moves further forward, the air from the air supply port 15 and introduction ports 5a and 5b of the piston 11 to the air supply hole 4 is blocked, and the air-fuel mixture continues to flow into the intake chamber 27b.

When the piston 11 reaches the top dead center, the air-fuel mixture already compressed in the combustion chamber 2 is ignited, and the piston 11 moves back. Then, as described above, the 10 groups of exhaust holes open first, and the exhaust gas is injected from the 10 groups of exhaust holes to the 7 groups of nozzles. As the piston 11 retreats, the main body 1 is rotated by the piston pin 12, and the exhaust gas collides with the 8 groups of turbine blades of the rotary impeller 20, causing the rotary impeller 20 to rotate. This rotation is transmitted to the main body 1 via the internal gear 22, small gear 20, and large gear 9, causing the main body 1 to rotate. Furthermore, since the exhaust gas also collides with the 8 groups of turbine blades of the main body 1, the main body 1 is rotated.

That is, the movement of the piston 11 rotates the main body 1, and the rotational force becomes stronger due to the exhaust gas.

As the piston 11 retreats, the 4 groups of air supply holes begin to open a little later than the 10 groups of exhaust holes, and the air-fuel mixture flows into the combustion chamber 2, scavenging the combustion chamber 2 and filling the inside of the combustion chamber 2 with the air-fuel mixture. The piston 11 then moves forward to compress the air-fuel mixture.

Incidentally, as shown in FIG. 7, it is convenient to assemble the piston pin 12 by dividing it into two parts, connecting the connecting parts with a sleeve 34, and fixing them with a clasp 35.

Further, a side rolling wheel 36 is rotatably attached to the piston pin 12 on the outside of the rolling wheel 14, and this side rolling wheel 35 is always in the curved groove 1.
If the piston pin 12 is formed so as to be in contact with the piston pin 7, the rotation of the piston pin 12 will be smooth.
