Abstract

PURPOSE:To reduce fuel consumption through reduction of engine vibration and engine weight by providing a structure where the center of a rotor, a rotating body and the center of a rotor housing, a rotated body coincide. CONSTITUTION:A reciprocating piston C is incorporated in a rotor B which moves along an inner wall of a rotor housing A which is concentric with the rotor, and is connected to a connecting rod D. A crank shaft E, a rotating body with its center at an eccentric position from the center of the rotor housing A is connected to the connecting rod D. One or more piston (s) C can be provided. In the above-mentioned condition, reciprocating motion is generated in the piston C by rotating the rotor B and the connecting rod D within the rotor housing A at a same speed. By utilizing this motion, strokes of intake, compression, explosion and exhaust can be achieved with a unit of 720 degrees by operating an intake valve and an exhaust valve. This allows reduction of fuel consumption through reduction of engine vibration, increased torque, motion resistance and engine weight.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field This invention relates to internal combustion engines for automobiles, industrial machinery, and agricultural machinery.

(2) Prior Art Conventional reciprocating engines require a large crankshaft to withstand strong impact force when converting the reciprocating motion of the piston into rotational motion, and they also suffer from a large loss of thermal energy. Furthermore, there are disadvantages such as installing accessories to prevent engine vibration and increasing the size of the engine due to an increase in the number of pistons.Also, due to the special structure of the rotor housing, the rotor has three contact surfaces. This burden is large, and therefore special materials are required, which makes it difficult to rotate at high speeds, and the special combustion chamber has drawbacks such as poor combustion efficiency.

(3) Problems to be solved by the invention: Reducing engine vibration, increasing torque, reducing motion resistance, and reducing fuel consumption by reducing engine weight.

Means to solve the problem Since the structure is such that the center of the rotor, which is a rotating body, and the rotor housing, which is a rotated body, coincide, the gap between the two can always be kept constant, and a slight airtightness can be maintained. Only resistance due to contact of the mechanism is generated between the two.

Furthermore, from the beginning to the end of the explosion process, the impact force via the piston and connecting rod is always transmitted to the crankshaft at an obtuse angle, so strong rotational force is generated throughout the entire explosion process. I can do it. This reduces the weight of the engine and increases energy conversion efficiency.

15) Function (a) The rotor housing is fixed to the chassis, the inner wall surface is composed of concentric circles, and an ignition device, fuel supply, supply device, intake and exhaust ports, intake and exhaust valves are set, and a cooling mechanism is also set. do.

(b) The rotor has an outer wall surface that slides along the inner wall surface of the rotor housing, and has a structure that allows the piston to reciprocate.

(c) Pistons should be a structure capable of reciprocating motion within the rotor, and any number of pistons, one or more, can be installed, but if there are more than one, they should be installed at equal intervals.

Furthermore, it is a structure that is connected to the Hunrod and equipped with a device to maintain secrecy. The highest position of the piston is the top dead center, and the lowest position of the piston is the bottom dead center. The distance between the top dead center and the bottom dead center is defined as the stroke, and the displacement is determined by integrating the bore and stroke.

(d) The connecting rod serves to connect the piston and crankshaft, and has a structure that can withstand the impact force generated during the explosion process.

(n) The center point of the crankshaft is set eccentrically from the center point of the rotor, so when both are rotated the same number of times, the expanding and contracting orbits are repeated in units of 180 degrees.This means that the crankshaft Reciprocating motion occurs in the piston when it is connected to the shaft, connecting rod, and piston. Therefore, the rapid expansion of the air-fuel mixture due to the explosion within the cylinder causes the piston to descend via the connecting rod, generating rotational force on the crankshaft.

(6) Example (Example of claim 1) (Top dead center and bottom dead center in the al explosion and exhaust processes are respectively A top dead center and A bottom dead center, and the top dead center and A bottom dead center in the suction and compression processes are Let the point and bottom dead center be B top dead center and B bottom dead center, respectively.

fb) When the cylinder reaches 0 degrees A top dead center and ignition occurs, an explosion occurs within the cylinder. At this time, the intake valve must be closed.

fc) The piston is pushed down by the rapid expansion of the air-fuel mixture due to the explosion, which generates rotational force on the crankshaft via the connecting rod, and since the relationship between the crankshaft and rotor is on an expanding trajectory, the cylinder rotates while expanding its volume. Start.

The fdl cylinder performs the explosion process up to 180 degrees A bottom dead center.

As the cylinder has passed the A bottom dead center of 1go degrees, it enters a contracting orbit as the rotation progresses, the piston is pushed up, and as the cylinder volume is reduced, exhaust gas is pushed out through the opened exhaust valve. This process is completed when the cylinder reaches 360 degrees B top dead center.

(f+, 360 degrees B) After the cylinder has passed the top dead center, the piston is pushed down as it expands, so the cylinder volume is expanded, and the suction valve is opened by the negative pressure generated at that time to perform the suction process.

(The cylinder that completed the suction process by B bottom dead center at gl 540 degrees will enter a contracted orbit after passing D bottom dead center,
The piston is pushed up, reducing the cylinder volume and performing the compression process. At this time, the exhaust valve must be closed.

(hl The cylinder again returns to the embodiment fbl (mouth) Example fal of claim 2 The top dead center in the explosion process is C top dead center, and the bottom dead center in the exhaust and intake processes is D bottom dead center .

fbl D Set the intake port and exhaust port in the rotor housing within a range of 90 degrees from the bottom dead center, and force the intake process.

The process of icl fcL(dl, (e)) is the same as in claim 1.

(di The cylinder that has passed the D bottom dead center of 180 degrees is
Due to the suction process in which suction is forcibly started, the exhaust process is simultaneously performed from the other exhaust port. Note that this process is completed by the 270 degree position.

(el) When the cylinder reaches the 270 degree position, the piston is pushed up by the contracting orbit, so the compression process is performed while reducing the cylinder volume until it reaches the 360 degree position.

(flThe cylinder returns to Example FC+ again (7)
Effects of the Invention As explained above, in this invention, the main components operate by circular motion, and the inertial force generated in the cylinder from the beginning to the end of the explosion process can be constantly transmitted to the crankshaft. It is an internal combustion engine that reduces engine vibration and weight, and also has high torque and high output. This has a significant effect on reducing fuel consumption.
