Description

eccentric rotary engine

The utility model relates to an internal combustion engine, in particular to an improvement technology for the main body structure of the internal combustion engine.

An engine is a machine that provides power to a motor vehicle or other equipment. The basic structure of a common engine is composed of a crankshaft connecting rod mechanism consisting of cylinders, pistons, connecting rods, crankshafts and flywheels. It is divided into two-stroke and four-stroke, because the energy conversion rate of two-stroke engine is too low, and the heavily polluted environment is gradually eliminated. Therefore, the most widely used is the four-stroke engine. The performance of the four-stroke engine is superior to that of the two-stroke engine, but there are still problems that are difficult to overcome, such as low power density, low energy conversion rate, poor intake and exhaust, and high vibration and noise.

The purpose of the utility model is to provide an eccentric rotor engine with smooth intake and exhaust, high energy conversion rate, stable operation, low vibration noise and high power density.

The scheme of the utility model is as follows: the utility model includes an intake and exhaust system, a lubrication system, a combustion system, a casing, front and rear end covers, an eccentric shaft, blades, and bolts, and an eccentric shaft and a The rotor is integrally formed with the eccentric shaft, the evenly distributed grooves on the rotor are provided with vanes sliding along the radial direction of the rotor, and the front and rear end covers are provided with mutually misaligned inlet and outlet ports.

Because the utility model adopts the structure of eccentric rotor and sliding vanes, and the organic combination of the prior art, the utility model can not only reliably realize the purpose of the invention, but also can make the four strokes of air intake, compression, work and exhaust continuous high-speed It has the advantages of simple structure, reliable performance, stable operation, high efficiency, low power consumption, and high energy conversion rate.

Below in conjunction with accompanying drawing, the scheme of the present utility model is described in further detail:

Fig. 2-Fig. 4 are the main structure schematic diagrams of the eccentric rotary engine;

Fig. 5 is a rotor structure diagram of an eccentric rotor engine;

Fig. 6 is a sectional view of the rotor structure A-A of the eccentric rotor engine;

Fig. 7 is a structural diagram of the rotor and blades of the eccentric rotary engine.

The eccentric rotary engine shown in Fig. 1 is composed of engine main body 1, intake system 2, exhaust system 3, combustion system 4 and lubricating system 5. The key technology of the utility model lies in the engine main body 1 . Fig. 2 and Fig. 3 are respectively two different structural forms of the single shell and the double shell of the utility model. Its monocoque (as Fig. 3, Fig. 4) its outside is shell 6, and shell 6 two ends bolts are connected and fixed front and rear end cover 7,8, and the inlet and outlet of mutual displacement are arranged on front and rear end cover 7,8. The casing 6 is provided with an eccentric shaft 9 different from the center of the casing 6 and a rotor 10 integrally formed with the eccentric shaft 9. The rotor 10 is provided with grooves 11 uniformly distributed along the axial direction. Connected (see Figures 5 and 6). There are vanes 12 sliding radially along the rotor 10 in the groove 11 . The top of the blade 12 is a circular arc, and the built-in magnetic block 13 at the bottom corresponds to the built-in magnetic block 14 of the eccentric shaft 9 of the rotor 10 (see FIG. 7 ). The difference between the double shell structure (as shown in Figure 2) and the single shell is that an inner shell 15 concentric with it is added in the outer shell 6, and rolling bodies are arranged between the inner and outer shells 15 and 6, and the inner shell 15 and the blades The top of 12 is hinged. At the same time, the built-in magnetic blocks 14, 13 on the rotor eccentric shaft 9 and the blade 12 are cancelled. The blower fan is fixed on the eccentric shaft 9 on the side of the front cover 7, and the air inlet is connected to the air inlet through the air inlet pipe, and the exhaust port is connected with the exhaust pipe. Its lubrication system 5 introduces lubricating oil into the central hole of the eccentric shaft 9 and directly flows into the middle hole of each groove 11 to the groove 11 to lubricate the blades 12 and adjust the positive and negative pressure in the groove 11. Its combustion system 4 can be accessed by the rear end cover (double shell structure) 8 or the shell (single shell structure) 6 .

When working (see Figure 3), the casing 6 is stationary, and the centrifugal force generated by the rotation of the rotor 10, the reaction force between the magnetic blocks 13 and 14, and the restriction of the casing 6 force the blades 12 to reciprocate in the radial direction of the rotor 10 in the groove 11 . When the rotor 10 rotates in the direction shown in the figure, along with the rotation of the rotor 10 and the sliding of the blades 12, the air fed into the air inlet is gradually compressed, and when any two adjacent blades 12 move to the area A, the air pressure is maximum The volume compression is the smallest, and it is ignited and burned under the action of the combustion system 4 . The high-temperature and high-pressure gas generated by the combustion will inevitably push the blade 12 to move to the B, C, and D areas with enlarged spaces in sequence with the inertia. Arrive at the exhaust port of the D area to discharge the exhaust gas, and the intake port sends in fresh air. A cycle process can be completed. When the double shell structure (see Figure 2) works, the inner shell 15 in the double shell rotates together with the blade 12 and the rotor 10, but the axes of the two are different, and the hinge between the blade 12 and the inner shell 15 On the one hand, the connection makes up for the angular velocity difference caused by the eccentric rotation, and at the same time, it can improve the wear degree of the top of the blade 12 . The cycle working process is the same as that of the single casing and the power is output by the eccentric shaft 9 .
