Description

Slide block type rotor engine

Technical Field

The invention relates to the technical field of engines, in particular to a sliding block type rotary engine.

Background

The existing internal combustion engine mostly adopts a piston connecting rod type or triangular piston type motion mode to obtain energy from expansion force generated by fuel oil combustion and convert the force of gas expansion into force of crankshaft rotation, and the fuel oil thermal efficiency of the existing internal combustion engine is only about 40% or even lower. The reasons for low thermal efficiency of the existing engine fuel are mainly insufficient combustion of the fuel, mechanical loss and exhaust loss.

Because the traditional engine adopts a valve type air inlet and exhaust mode to carry out air exchange of the cylinder, the conditions that exhaust gas is not completely discharged and new mixed gas is discharged along with the exhaust gas can be caused, and fuel loss is caused. In the traditional engine, a crankshaft connecting rod is adopted to push a piston to reciprocate, so that the expansion force generated by fuel combustion in a cylinder is converted into the rotating force of a crankshaft through the crankshaft, the included angle between the connecting rod and the crankshaft is changed continuously at the initial stage of fuel combustion, the included angle between the connecting rod and the crankshaft is 90 degrees, the power is not output favorably, and when the piston reaches a lower extreme point, the mechanical loss caused by the downward inertial force of the piston during upward movement is overcome. The valve train rotation consumes a portion of the power. When the traditional engine finishes working, in order to exhaust the exhaust gas cleanly, the exhaust valve is opened before the piston reaches the lower-most point, and the pressure in the cylinder is very high and even exceeds 14 mpa. Causing heat loss from the exhaust.

The housing 1 is provided with a gas discharge passage 12 and a spark plug 7 at positions on both sides of the first contact line 11, respectively.

Note that the inner side wall of the barrel body 41 and the outer side wall of the mandrel 5, the outer side wall of the barrel body 41 and the inner side wall of the housing 1, and at the second contact line 53 and the first contact line 11, the outer bottom wall of the inner bottom wall of the barrel body 41 and the inner bottom wall of the outer bottom wall front end cap 2 of the barrel body 41, and the opening end face of the barrel body 41 and the inner bottom wall of the rear end cap 3 form a friction seal. The front end cover 2, the rear end cover 3 and the shell 1 are also arranged in a sealing mode, and sealing can be achieved by controlling machining precision or sealing can be achieved through sealing devices (such as sealing strips, sealing rings and sealing gaskets) in the prior art.

The working principle is as follows: as shown in fig. 5-8, when the rotor 4 rotates clockwise, the contact line between the slider 6 and the outer sidewall of the spindle 5 and the second contact line 53 divide the second cavity 54 into an air inlet cavity (located behind the clockwise direction) and an air compressing cavity (located in front of the clockwise direction), and the contact line between the slider 6 and the inner sidewall of the housing 1 and the first contact line 11 divide the first cavity 13 into a working cavity (located behind the clockwise direction) and an air discharge cavity (located in front of the clockwise direction). In fig. 5, when the rotor 4 rotates clockwise under the action of the gas mixture, the space of the gas inlet cavity gradually increases, the pressure decreases, the gas mixture formed in the carburetor is sucked through the first passage 51 and the gas inlet passage 31, and the volume of the gas compression cavity gradually decreases, so that the gas mixture inside the gas compression cavity is compressed and enters the fourth passage 32 through the second passage 52 (at this time, the second end of the fourth passage 32 abuts against the end surface of the barrel 41 to form a friction seal and is completely staggered with the gas inlet of the third passage 413). In fig. 6, the rotor 4 continues to rotate clockwise, the slide block 6 slides through the exhaust channel 12, the exhaust is finished, the working chamber is communicated with the exhaust channel 12, the working is finished, the compression chamber continues to compress the gas mixture, and the air inlet chamber continues to suck the gas mixture. In fig. 7, the rotor 4 continues to rotate clockwise, and the second end of the third channel 413 located at the bottom surface of the barrel 41 is aligned with and communicated with the second end of the fourth channel 32 located on the rear end cover 3 when the compression chamber is nearly completely compressed, so that the compressed gas mixture in the compression chamber rapidly rushes into the combustion chamber (the groove 412 is formed with the inner side wall of the housing 1). When the rotor 4 continues to rotate clockwise, until the second end of the third channel 413 and the second end of the fourth channel 32 are completely staggered, gas compression is finished, the spark plug 7 is ignited, gas mixture in the combustion chamber is ignited, the gas mixture is combusted and expanded to push the sliding block 6 and the rotor 4 to rotate clockwise, the space of the exhaust cavity is gradually reduced, and waste gas in the exhaust cavity is exhausted through the exhaust channel 12. In fig. 8, the rotor 4 and the slide block 6 continue to rotate clockwise until the compression of the compression cavity is finished, and the air intake of the air intake cavity starts, and the next cycle is started.

The sliding block type rotary engine is compact in structure, and a gas distribution mechanism and a cooling mechanism of a traditional sliding block type rotary engine are omitted, so that the structure is simpler. And air intake, compression, do work, the exhaust is relatively independent for the clean air intake of exhaust is sufficient. The force when the fuel is combusted and expanded directly pushes the slider 6 to rotate the rotor 4, which improves the fuel utilization. The structure that the pressure air cavity is separated from the work cavity is adopted, so that the volume of the work cavity is larger than that of the pressure air cavity, the expansion force of fuel combustion is utilized to the maximum extent, the pressure during exhaust is reduced, and the thermal efficiency of the fuel is improved, thereby achieving the purpose of saving oil.

Wherein the volume of the first cavity 13 is preferably larger than the volume of the second cavity 54. The second cavity 54 has an intake compression function and the first cavity 13 has an exhaust function. The volume of the first cavity 13 is larger than that of the second cavity 54, so that the expanded volume of the fuel is larger than the compressed volume, and the working cavity is positioned on the outer circle of the rotor 4, so that the moment arm of the slide block 6 acting on the rotor 4 is longer, and the output torque force is larger.

Wherein both the outer side wall and the inner side wall of the tub 41 are provided in a cylindrical shape. The cylindrical shape is simple to manufacture. Of course, the shape of the rotary body can be a truncated cone or any other shape.

The through slot 411 penetrates through the side wall of the barrel body 41 along the radial direction, the distances between the inner side wall of the shell 1 and the outer side wall of the mandrel 5 along each radial direction of the barrel body 41 are equal, and the length between the two ends of the sliding block 6 is a fixed length. As shown in fig. 9, the outer side wall of the mandrel 5 (which may be cylindrical or may be other shapes) and the inner side wall (non-cylindrical) of the housing 1 are shown in a cross-sectional view at a position where the distances from the outer circumference line to the inner circumference line in each radial direction of the barrel 41 are equal (a).

The both ends of slider 6 are convex cambered surface and are tangent contact with the lateral wall of the inside wall of shell 1 and the lateral wall of dabber 5 respectively.

One of the outer side wall of the spindle 5 and the inner side wall of the housing 1 is provided in a shape of a revolution solid.

The inner side wall and the outer side wall of the barrel body 41 are both cylindrical, and one of the outer side wall of the mandrel 5 and the inner side wall of the shell 1 is cylindrical and is arranged off-axis with the barrel body 41.

The length between the two ends of the sliding block 6 is a telescopic length. If the both ends of slider 6 set up to elastic material to satisfy its both ends and contact and form friction seal with the lateral wall of dabber 5 and the inside wall of shell 1 respectively all the time. In this case, the distance from the outer side wall of the mandrel 5 to the inner side wall of the casing 1 in each radial direction of the barrel 41 may not be equal. If the outer side wall of the mandrel 5 and the inner side wall of the shell 1 are in a cylindrical shape coaxially arranged, the barrel-shaped body 41 is in a cylindrical shape eccentrically arranged with respect to the mandrel 5.

Grooves 61 are formed in two ends of the sliding block 6, sealing strips 62 are arranged in the grooves 61 in a sliding mode, and a pressure spring 63 is arranged between the bottom wall of each groove 61 and the bottom wall of each sealing strip 62. This ensures that the sealing strip 62 always meets the inner side wall of the housing 1 and the outer side wall of the spindle 5 and forms a friction seal, as shown in fig. 4.

The inner wall of the barrel-shaped body 41 and the outer side wall of the mandrel 5 are similar in rotary body shape, the outer side wall of the barrel-shaped body 41 and the inner side wall of the shell 1 are similar in rotary body shape, the mandrel 5 and the shell 1 are coaxially arranged, and the barrel-shaped body 41 and the mandrel 5 are arranged in an off-axis mode
