Description

O-ring type rotary engine

The present invention relates to an O-ring type rotary engine, and more particularly, the rotor rotates in a circular motion, and the operation is performed so that the rotational stability and initial explosive force act as the rotor's rotation force to the maximum, thereby maximizing thermal efficiency and low weight and The purpose is to enable low pollution.

In general, the engine is largely divided into a reciprocating engine and a rotary engine. The reciprocating engine performs suction, compression, expansion, and exhaust stroke by a reciprocating motion of a piston housed in a cylinder. The rotary engine converts the linear motion into a rotary motion and uses it as a power source. The rotary engine, which has been put to practical use, has an intake, compression, expansion, and exhaust stroke as eccentric rotation of a triangular rotor in an elliptical combustion chamber. This is the output of the rotary motion.

However, the reciprocating engine of the conventional engine as described above, the rotational speed is increased because the direction of inertia force and the direction of movement of the connecting rod in the opposite direction at the top dead center and the bottom dead center where the piston reaches the top and bottom dead centers in the opposite direction. There was a problem that is limited to a certain speed or less, the maximum explosive force occurs initially in the expansion stroke, but at this time, there was a problem that does not maximize the explosive force by the rotational force at the top of the top dead center affected by the inertia of the piston.

In addition, in the case of the conventional rotary engine, since the rotor is eccentrically rotated, the rotational safety is lowered, and there is a problem that the efficiency of the gas is degraded due to poor sealing of the gas due to its structural characteristics.

Therefore, the present invention is to prevent the output loss due to the inertia loss and the output loss due to the eccentric rotation of the rotary engine in the reciprocating engine as described above, to form a cylindrical rotor chamber inside and separate the outside And a rotor housing the combustion chamber and a rotor housed in the rotor housing and rotated in a circle.

It is preferable to carry out with the heater 43.

Meanwhile, in the embodiment of the present invention, when the combustion chamber 40 and the rotor 20 are made of only one movable projection 21, the rotor 20 is formed in an even number of rows for efficient operation of the engine, but one side of the rotor housing 10 ) Is connected to the combustion chamber 40 of the other rotor housing 10 and the compression tube of the other rotor housing 10 is preferably configured to be cross-connected to one side of the rotor housing 10.

Hereinafter, the operation of the present invention will be described.

In the present invention comprising a rotor housing 10 having a combustion chamber 40 as described above, and a rotor 20 that is housed in the rotor chamber 11 of the rotor housing 10 and rotated in a circle, the combustion chamber 40 In the case of a low speed type in which two or more movable protrusions 21 of the rotor 20 are provided, one combustion chamber 40 is in a compressed state and the other combustion chamber 40 is in an inflated state. At the same time, one side of the movable projection 21 of the rotor 20 is rotated, and the intake stroke of the outside air is sucked through the one side suction expansion valve 50 and rotated while the rotor 20 continues. The air sucked through the intake stroke by the other movable protrusion 21 from the time when the movable protrusion 21 on the other side passes through the partition valve 31 is transferred to the combustion chamber 40 through the compressed exhaust valve 60. Compression is supplied to perform a compression stroke, and the compression The fuel is injected into the air compressed and supplied to the combustion chamber 40 at the time when the movable protrusion 21 for cleaning is rotated 180 ° and passes through the partition valve 31, and then ignited and exploded through the suction expansion valve 50. The rear surface of the movable protrusion 21 which is expanded and introduced into the rotor chamber 11 and passed through the partition valve 31 is rotated.

Then, from the time when the movable projection 21 rotated by the expansion gas passes through the partition valve 31 by rotating 180 °, the expansion gas is moved through the compressed exhaust valve 70 by the opposite movable projection 21. Exhaust to the outside air and the above process is repeated to operate the engine.

On the other hand, in the case of a low speed type in which the combustion chamber 40 and the movable protrusion 21 of the rotor 20 are integrally connected to each other and the compression line is crossed, the suction expansion valve 50 of the one rotor housing 10 is in a suction state. When air flows into the one side rotor chamber 11, the air compressed by the other rotor 20 flows in through the compression pipe. At this time, the combustion chamber 40 of the other rotor chamber 11 has an expansion stroke in which the mixed gas explodes. This is a state where it is made.

As described above, in the combustion chamber 40 at the moment when the movable projection 21 passes through the partition valve 31 in the state in which the suction stroke of the air is completed in the one side rotor chamber 11 and the compression stroke in the combustion chamber 40 is completed. An expansion stroke is formed in which the mixed gas is exploded and rapidly flows into the rotor chamber 11 to rotate the movable protrusion 21. The air introduced to the opposite side of the movable protrusion 21 is supplied to the other combustion chamber 40. As the two rotors 20 are organically operated, they rotate at high speed.

Therefore, the present invention can rotate the high gas pressure at the beginning of the expansion stroke, and can exhibit about twice as much rotational force as the reciprocating engine, and the moving speed of the work performed at the beginning of the expansion stroke, that is, the movement speed of the rotor, is reciprocated. It is about 2.5 times faster than the engine, minimizing heat loss.

In addition, since the rotor moves in a circular motion, rotational stability is improved, and the ignition and combustion timing can be freely selected, and there is no fear of knocking. Therefore, the thermal efficiency is improved by improving the compression ratio.

In addition, in the low speed type, there are two expansion strokes per rotation of the rotor and the crank mechanism is omitted, which is advantageous for miniaturization and high horsepower, and the weight and volume per horsepower can be reduced to 1/6 of the reciprocating engine. There are alternate strokes in two cylinders connected in parallel. Each cylinder is small in size and does not have a crank mechanism, reducing the weight and volume per horsepower to one-half of the reciprocating engine.

On the other hand, since the combustion chamber is separately installed, the initial combustion is started at a high temperature, thereby reducing the emission of harmful gases such as HC and CO. The vortex of the compressed air is promoted, and nitrogen oxide is generated since the combustion chamber is introduced into the cylinder after some combustion. This is very useful to be minimized.
