Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piston type engine,

The present invention relates to an engine, and more particularly to a piston-type rotor engine and an engine device composed of the same.

In the prior art, the fuel engine is divided into a reciprocating engine and a rotary engine. The reciprocating engine has a history of more than a hundred years of development and has the advantage of improved technology, safety and reliability. On the other hand, there is a disadvantage that the efficiency is low, the conversion rate is less than 50%, the noise is large, the carbon emission is high, and the pollution is severe. The rotor piston engine is small in volume, light in weight, lighter in weight, has a one-fold increase in conversion efficiency, and the two-cylinder rotor engine has the same stability and power as the six-cylinder reciprocating four- There are advantages. On the other hand, the disadvantages are that the emissions are below or above the standard, the temperature is high, the noise is high and the fuel consumption is high. Both of these vehicles have high noise and high fuel consumption.

In addition, in 2013, smog influenced 25 provinces and 100 medium and large cities in China, and the nation's average smog days reached 29.9 days, the highest in 52 years. Especially in the winter, nationwide foggy weather repeats, attracting people's attention, and a way to eliminate fog has also become a critical issue. The International Agency for Research on Cancer (IARC) has already recognized air pollution as a carcinogen at the Liang meeting, and has also been accredited by experts. More specifically, airborne particulate PM 2.5 is a human carcinogen, and automobile soot is a major cause of PM 2.5.

Based on this, the present invention solves the above-mentioned disadvantages of the prior art by providing a piston type engine and an engine device constituted thereof.

In order to achieve the above object, the present invention adopts the following technical solution.

The piston-type engine includes a housing, a crankshaft in the housing, and two sets of rotor pistons, the two sets of rotor pistons being symmetrically disposed at opposite ends of the crankshaft, and the two sets of rotor pistons being separated by a fixed frame .

The structure in the present technology is more stable and improved the conventional single rotor piston structure, the two sets of rotor pistons are installed in the cylinder, and the two sets of rotor pistons form a symmetrical structure with a dumbbell shape, And realize mutual conversion. Here, the load is greatest when one rotor piston is working, where the other rotor piston releases the stored position energy and reduces the load on the working rotor. Therefore, the two sets of rotor pistons compensate position energy during operation and can form a double structure, good balance of motion balance, and more stable operation. In addition, the cylinders arranged symmetrically reduce the large noise and vibration phenomenon during the operation of the engine, extend the useful life of the engine, reduce noise generated during the use of the engine, and are practical.

Preferably, the fixed frame and the housing are integrally formed, and the integral structure is very stable.

More preferably, the rotor piston includes a combustion chamber, a crankshaft in the combustion chamber, and a piston body, the cross-section of the combustion chamber being formed by an ellipse, an air intake port being formed at an upper portion of the combustion chamber, And an ignition plug is inserted in the center of the other side of the combustion chamber. The piston body is engaged with the crankshaft by an internal gear, and the cross section of the piston body has a circular shape with 360 degrees. Which is similar to a disk with three co-directional hooks. Wherein each of the discs is a circular arc-shaped protruding end with a large head end and a small end, the arc of the head end of the protruding end is concave, and the arc of the end is formed concavely toward the head end, And is an arc formed toward the end. An arc-shaped force-receiving surface is formed between both sides of the protruding end and the apex angle of the piston body, wherein the area of the arc-shaped force-receiving surface on the rotational direction side is equal to the area of the arc- Area. The ignition direction of the combustion chamber corresponds vertically to the concave groove of the head end. The shock wave of the explosion pushes directly into the concave groove. Like a sail of a fishing boat, it receives a force in one direction. Prevent the reaction force of explosion. Impact force is basically converted to 100% power energy. And an arc-shaped force-receiving surface inclined to the head end is provided in the relatively small combustion chamber space at the end. So that a small amount of reverse fuel of the head end is returned to the combustion chamber again to prevent air leaks. The structure having a large head end and a small tip makes the impact force rotate along the head end direction and rotates several times in the combustion chamber and is sufficiently burnt to reduce carbon dioxide emissions.

More preferably, a sealing ring is inserted in the center of the protruding end. The sealing effect is strengthened to make the operation more smooth.

The engine unit includes a crankshaft, which is connected to the power output shaft by a planetary gear, and a power unit for compensating the power of the flywheel is fixed to the power output shaft. In this technology, the conventional pulley transmission structure is improved to the whole integrated structure, the noise is small, and the influence of the conventional pulley on the overall aesthetic effect is solved. In addition, when the pulley rotation is fatigued, it easily slips and generates noises, and since the reverse wheel and the fan can not normally work, the high temperature phenomenon of the automobile engine may easily occur, and the crankshaft of the engine may be frayed. The present invention saves power and can operate with relatively high output at relatively low engine speeds, low noise, reduced working hours and losses, and extended engine service life. In the present invention, a conventional flywheel power compensator is added to a conventional high-density, high-ratio annular-type gear fixing disk, and when the engine is normally operated, the engine is normally rotated, Energy inertia is formed. The load on the rotor piston is greatest when the rotor piston of the automobile engine is operating at the rising point. At this time, the flying wheel power compensation device releases the stored energy to overcome the load peak when the rotor piston operates at the rising point. In addition, since the diameter of the flying wheel power compensating device is larger than the diameter of the rotor engine piston, the potential energy generated in the flying wheel power compensating device is larger than the maximum load that the rotor piston works. Therefore, the flying wheel power compensating device imparts powerful working energy to the rotor, and operation is simpler and saves time and power.

More preferably, in the engine, a cooling system is connected to one end remote from the flying wheel power compensating device. The cooling system includes a water cooler, the water cooler interlocks the cooling water circulation by a water pump, Is interlocked by the crankshaft and the transmission gear, and the cooling fan is fixed to the other side of the water-cooler. In the present technique, the crankshaft actuates the water pump in operation and the pump interlocks the circulation of the cooling water. Further, the other side of the water cooler blows to the cooling fan to improve the cooling effect, and the oil pump and the fan are not consumed in the process of use, and the normal and stable operation of the fan and the oil pump is ensured.

The symmetrically arranged rotor effectively reduces the vibration of the engine. The relatively large volume of combustion space in the direction of rotation allows sufficient combustion to be achieved, plus a mechanical leverage mechanics structure and an effective sealing device to thoroughly address the technical disadvantages of high engine temperatures, high noise and emissions above standard .

Both ends of the crankshaft 14 are connected to the power output shaft 8, the engine oil system, and the water cooling system, respectively, in a gear transmission structure. In Fig. 1, 3-1 and 3-2 are two sets of rotor pistons 3 symmetrically arranged with respect to the fixed frame 2, and when they are arranged symmetrically, they are offset from the kinetic energy in the opposite direction, . The fixed frame and the housing are made of a monolithic structure, and the monolithic structure has a very stable effect.

More preferably, the rotor piston includes a combustion chamber, a crankshaft in the combustion chamber, and a piston body, the cross-section of the combustion chamber having an elliptical shape, an air inlet is formed at an upper portion of the combustion chamber, an air outlet is formed at a lower portion thereof, And the piston body is meshed with the crankshaft by an internal gear, and the cross section of the piston body is formed in a triangular structure in which each side is a circular arc, and the three angles of the piston body are extended to both sides And an arc-shaped force-receiving surface is formed between both sides of the protrusion end and the apex angle of the piston body. Here, the area of the arc-shaped force-receiving surface on the rotational direction side is the arc- Is larger than the area of the force-receiving surface of.

More preferably, a sealing ring is inserted in the middle of the projecting end.

The engine disclosed in the present invention is a dumbbell double piston structure, and the object of the structure is to improve the equilibrium of the kinetic energy of the two rotors of the engine and the mutual compensation of energy, and the two pistons are connected to each other by one fixed shaft , The two pistons are arranged symmetrically on both sides of the central axis to reach the purpose of weight balance. The working points of the two pistons are plus 180 degrees and minus 180 degrees, respectively, and their purpose is to compensate for each of the two pistons at work. Further, the greatest advantage of the present invention is that the output and stability to be worked are the same as the six cylinder working efficiency and stability in the prior art, with a dumbbell double rotor structure, so that the fuel consumption of the above technique is only one third Reduce emissions by 60%.

Example 2.

As shown in Fig. 1, in the embodiment of the present invention, an engine device is further provided and includes a crankshaft, the crankshaft is connected to the power output shaft by a planetary gear, and the power output shaft is fixed to the power output shaft. One end of the crankshaft 14 fixes the flying wheel power compensator 9 to the planetary gear 12. [ Preferably, the flying wheel power compensating device 9 is an axial force compensating device with the application number 92208890.X. In order to complete the work of the same output using the above-described axial force compensation device, a conventional output engine in the prior art can be used. In addition, the idling of the engine is reduced by half, and when it is about 400 revolutions, the running fuel is reduced by half.

More preferably, the engine is connected to a cooling system at one end far away from the flying wheel power compensator, the cooling system includes a water cooler, the water cooler interlocks the cooling water circulation by a water pump, And the cooling fan is fixed to the other side of the water cooler. The cooling device and the lubricating device, which are two sets of devices, are interlocked by the gears of the front axle head 16 remote from the flying wheel power compensating device 9 in the crankshaft 14. [ The cooling device includes a water pump 19, a cooler and a cooling fan. The cooler interlocks the cooling water circulation by the water pump 19 and the water pump 19 is connected to the gears of the shear shaft 16 And is linked directly to the crankshaft 14 of the engine so that when the engine is rotated, the cooling device is also rotated to assist the rotation. In the prior art, all of the cooling systems using pulley drives have been so complex that the present invention simplifies the structure and makes manufacturing and use more convenient. The lubrication apparatus includes an oil box at the bottom of the housing 1 and an oil pump gear meshing with the transmission shaft head 16 gear and is the same as the prior art lubrication system and will not be described any further.

2, the rotor piston 3 includes a combustion chamber, a crankshaft 14 in the combustion chamber and a piston body 30, the cross section of the combustion chamber being elliptical, And an ignition plug is inserted in the center of the other side of the combustion chamber. The piston main body 30 is meshed with the crankshaft 14 by an internal gear to be connected to the piston body (not shown) The three sides of the piston main body 30 extend to both sides to form a protruding end 34 and the both ends of the protruding end 34 and the side surface of the piston main body 30 The arc-shaped force surface is formed between the apexes, and the area of the arc-shaped force surface on the rotational direction side is larger than that of the arc-shaped force surface on the other side. Compared with a conventional rotor engine, the projecting end 34 and the arcuate force-generating surface formed thereby form a relatively large space in the rotational direction of the combustion chamber. There are two advantages: first, the arc-shaped surface of the work is interlocked with the fuel rotation, and second to even multiple burns. If the combustion is sufficient, the amount of contaminants in the exhaust gas is very small. Therefore, if the combustion efficiency is very high, the pollution is very small. Secondly, when receiving a force, a relatively large space in the direction of rotation and a relatively large force acting on one end are very large, and compared to a conventional rotor engine, the transmission effect is very good. When the explosive force of the fixed angle at the time of ignition of the engine and the rotation angle of the rotor piston (3) are in a straight line, it resolves the back force generated by the square impact force at the time of the conventional Mazda combustion explosion and the sound of hitting the cylinder, So that the impact on both sides of the rotor generated in the 360 ° explosion direction is prevented, so that the burning fuel and the high temperature are not leaked to the outside. It solves the technical disadvantages such as high engine temperature, high noise and emission exceeding the standard.

In the present invention, the rotor engine is not described further, as other technologies are the same as those of the prior art.

Taking the above into consideration, the piston type engine and the engine device constituted by the present invention provided by the present invention are simpler in structure at the same output condition, the parts are reduced by 60%, the volume is 1/3 and the weight is 1/5 , And the water pump 19 at the front of the engine and the cooling fan 23 are connected to each other without exposure. It has few components, easy construction, easy to manufacture, saving manpower, resources and power, and reducing environmental pollution.

The description of the technical solution is merely a prior art technique and does not limit the form disclosed in the entirety or the present invention. Based on the embodiments of the present invention, any other type of technical solution obtained without any inventive step is covered by the scope of the present invention.
