The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The invention will be described in detail below with reference to the drawings and the detailed description.
The invention discloses an engine air inlet structure and a triangular rotor engine with the same. Among them, the engine intake structure is an important component in the engine, which directly affects the intake efficiency, stability and performance of the engine. In the design based on the triangular rotor engine, an innovative engine air inlet structure is adopted, and the novel engine air inlet structure has a unique working principle and an implementation mode.
The method comprises the following steps: in the embodiment shown in fig. 1, the engine intake structure realizes the intake function through the vent hole 10 and the intake additional chamber cavity 9 vertically opened on the cylinder block 8. The vent hole 10 and the air inlet auxiliary chamber cavity 9 are cylindrical, and the vent hole 10 is positioned above the working chamber and communicated with the working chamber. The intake plenum chamber 9 is located above the vent 10 and communicates with the cavity of the end cap 1, which is designed to improve the intake efficiency and airflow stability of the engine.
In order to achieve pressure equalization during intake, the engine intake structure is also provided with a piston 3 and an elastic member 5. One end of the elastic piece 5 is abutted against the bottom of the piston 3, and the other end of the elastic piece 5 is abutted against the bottom of the air inlet auxiliary chamber cavity 9. At the same time, the top end of the piston 3 is in contact with the cam shaft 2, and the cam shaft 2 and the eccentric shaft 6 rotate synchronously. When the furthest point of the camshaft 2 from the axis moves to the right below and the elastic piece 5 deforms, the distance from the bottom surface of the air inlet auxiliary chamber cavity 9 to the axis of the camshaft 2 is larger than the distance from the bottom end of the piston 3 to the axis of the camshaft 2, so that the piston 3 can repeatedly reciprocate up and down under the drive of the camshaft 2.
In the above embodiment, the vent hole 10 is formed in the cylinder 8, the vent hole 10 is located at the middle between the air inlet auxiliary chamber 9 and the working chamber, and the vent hole 10 is formed in a straight line. Accordingly, the vent holes 10 can be opened according to the actual design.
As shown in fig. 2, the end cover 1 includes a front end cover 120 and a rear end cover 110, the vent hole 10 is opened on the cylinder 8 and the rear end cover 110, the vent hole 10 is U-shaped, the lowest part of one end of the vent hole 10 communicating with the air inlet auxiliary chamber cavity 9 is in the same horizontal plane with the bottom surface of the air inlet auxiliary chamber cavity 9, and the corners of the vent hole 10 are rounded. It can be seen that the ventilation holes 10 in the present embodiment are formed in a U shape, and ventilation channels are formed on the cylinder 8 and the rear end cover 110, so that the treatment mode increases the ventilation length, but effectively improves the uniformity of air intake. Meanwhile, the resistance of internal circulation is avoided through the design of the round corners.
In one embodiment, the vent 10 is open coaxially with the intake additional chamber cavity 9. The design has the advantage of ensuring the tight butt joint between the vent hole 10 and the air inlet auxiliary chamber cavity 9 and ensuring the air flow to be unobstructed.
In one embodiment, the ratio of the diameter of the vent 10 to the inlet plenum chamber 9 is 1:2-2:3. Through reasonable diameter proportion, the entering and distribution of the air flow can be optimized, and the air flow resistance is reduced.
In an embodiment, a sealing ring 4 is provided on the outer wall of the piston 3. Through the arrangement of the sealing ring 4, gas leakage can be effectively prevented, sealing performance is improved, and normal operation of an air inlet system is ensured.
In one embodiment, the outer wall of the piston 3 is grooved in the circumferential direction and the sealing ring 4 is embedded therein. By embedding the seal ring 4 into the piston 3 through these grooves, the fixing effect of the seal ring 4 can be further enhanced, preventing it from loosening or falling off.
In an embodiment, the elastic member 5 is a compression spring, which can fix one end at the top of the inner wall of the piston 3 and is in contact with the bottom of the air inlet auxiliary chamber 9, so as to realize compression deformation of the spring and pressure balance between the air inlet auxiliary chamber 9 and the working chamber.
In one embodiment, the elastic member 5 is a coil spring. The spiral spring can provide good linear elastic characteristics and anti-fatigue capability, adapt to pressure changes under different working conditions, and improve the running efficiency of the engine.
In this engine intake structure, the vent hole 10 and the intake air auxiliary chamber 9 are provided for the purpose of improving the engine intake efficiency and air flow stability. Through the vent hole 10 and the air inlet auxiliary chamber cavity 9 which are coaxially arranged, in the running process of the engine, the external air enters the air inlet auxiliary chamber cavity 9 through the vent hole 10, and then enters the working chamber of the engine through the vent hole 10 which is connected with the working chamber through the air inlet auxiliary chamber cavity 9.
Meanwhile, the design of the piston 3 and the elastic piece 5 arranged in the air inlet auxiliary chamber cavity 9 can realize pressure balance between the air inlet auxiliary chamber cavity 9 and the working chamber. When the furthest point of the camshaft 2 from the axis moves to the right below and the elastic piece 5 deforms, the distance from the bottom surface of the air inlet auxiliary chamber cavity 9 to the axis of the camshaft 2 is larger than the distance from the bottom end of the piston 3 to the axis of the camshaft 2, and the pressure balance effect is realized through the geometric relationship.
When the engine is operating, the camshaft 2 drives the piston 3 to move up and down. When the most distant point of the camshaft 2 from the axis moves to the right below, the top end of the piston 3 is in contact with the camshaft 2, and at this time, the distance from the bottom surface of the air inlet auxiliary chamber 9 to the axis of the camshaft 2 is greater than the distance from the bottom end of the piston 3 to the axis of the camshaft 2. This geometrical relationship causes the elastic member 5 to deform, maintaining the pressure balance between the inlet plenum chamber 9 and the working chamber.
The other scheme of the application is a triangular rotor engine, the triangular rotor engine adopts the air inlet structure, the triangular rotor engine comprises a cylinder body 8 and an end cover 1, a working chamber is arranged on the cylinder body 8, a rotor 7 is arranged in the middle of the working chamber, and the rotor 7 is connected with an eccentric shaft 6 through gear engagement on the rotor 7; the end cover 1 is fixedly provided with a cam shaft 2, and the eccentric shaft 6 transmits torque to the cam shaft 2 through a chain, a belt or a gear, so that the cam shaft 2 is driven to rotate, and the cam shaft 2 and the eccentric shaft synchronously rotate; the side surfaces of the working chamber are respectively provided with an air inlet channel 11 and an air outlet channel 12. When the rotor 7 moves, the working chamber is divided by the rotor 7 to form three mutually isolated areas, namely a first working area 13, a second working area 14 and a third working area 15.
The working process of the triangle rotor engine is as follows: an air inlet auxiliary chamber is arranged on the cylinder body 8, and an air vent 10 connected with the working chamber is arranged below the air inlet auxiliary chamber cavity 9; the air inlet auxiliary chamber cavity 9 is provided with a piston 3, the piston 3 is driven by the cam shaft 2 and the elastic piece 5 to reciprocate, the cam shaft 2 is driven by the eccentric shaft 6 through a chain or a belt or a gear, the cam shaft 2 and the eccentric shaft 6 synchronously rotate, and the air inlet auxiliary chamber cavity 9 is communicated with the working chamber through an air vent 10 on the cylinder body 8.
As shown in fig. 3, each time during the air intake process of the working chamber cavity, the elastic member 5 drives the piston 3 to increase the volume of the air intake auxiliary chamber, and air enters the air intake auxiliary chamber cavity 9 through the air intake channel 11, the working chamber and the vent hole 10 on the cylinder body 8. After the intake of the working chamber cavity is completed, the camshaft 2 drives the piston 3 to reduce the volume of the intake auxiliary chamber cavity 9, and air in the intake auxiliary chamber cavity 9 is pressed into the working chamber through the vent hole 10 of the cylinder 8. By this intake mode, the intake air amount is increased, that is, the compression ratio is increased.
In the practical application process, the cam lift of the cam shaft 2 can be adjusted according to the requirement, so that the volume of the air inlet auxiliary chamber cavity 9 is adjusted, and finally, the compression ratio is adjusted.
Taking a 300cc displacement, gerotor engine for example, the maximum volume (including the combustion chamber) of the engine is 340cc and the minimum volume (including the combustion chamber) is 40cc, the compression ratio is 340/40, i.e., 8.5.
If the intake structure of the present invention is adopted, an intake additional chamber with a diameter of 8cm is provided on the engine block 8, and the lift of the camshaft 2 is 3cm, the intake volume can be theoretically increased by 3.14×8×8/4*3, i.e., 150cc, the compression ratio is (340+150)/40=12.4, and the compression ratio is increased by 46%.
Therefore, the air inlet structure of the invention greatly improves the compression ratio of the engine and has obvious use effect. Specifically, the air inlet efficiency of the engine is improved, so that the engine can more effectively introduce external air, the oxygen supply is increased, the combustion efficiency is improved, and the energy loss is reduced. Meanwhile, the stability of the air flow is improved, the resistance of the air flow is reduced, the adverse effects of vortex, turbulence, pressure pulsation and the like are reduced, the air flow distribution is optimized, and the stability and the reliability of the engine are improved. And secondly, the pressure balance is realized, the pressure fluctuation of an air inlet system is reduced, the running noise and vibration are reduced, and the service life of the engine is prolonged. Then, the elastic piece 5 adopts a wave spring, has good linear elastic characteristic and anti-fatigue capability, can adapt to pressure changes under different working conditions, and improves the performance and reliability of the engine. Finally, the engine air inlet structure is relatively simple, easy to manufacture and maintain, production cost and maintenance cost are reduced, and the economy of the engine is improved.
The present embodiment is merely illustrative of the invention and is not intended to limit the invention, and those skilled in the art, after having read the present specification, may make modifications to the embodiment without creative contribution as required, but are protected by patent laws within the protection scope of the present invention.
