[0002] In existing technology, the conventional engine design is a piston-driven design, meaning a reciprocating piston is used to perform work through the four strokes: intake, compression, power, and exhaust. In this engine design, the combustion chamber and gas compression chamber are integrated and share the same space. Therefore, it is difficult to precisely control the compression ratio. The engine's power efficiency is low and needs to be optimized and improved. Content of the utility model

[0003] The utility model aims to solve at least one of the prior art technical problems. To this end, one object of the present invention is to provide a camshaft engine.

[0004] The technical solution of the utility model is as follows: a camshaft engine characterized in that it comprises the following: a housing, a cam, an output shaft, a guide plate, a spring, an ignition device, a gas compression device and an oil supply device.

[0005] The interior of the housing contains a cam chamber, and the cam rotation is located within this chamber. The cam comprises a rotating part and a protruding part. The output shaft is rotatably mounted to the housing and rigidly connected to the rotating part. The protruding part is in contact with the inner circumferential wall of the cam chamber.

[0006] The movable guide plate is slidably mounted on the inner circumferential wall of the cam chamber and, under the action of the spring, is always in contact with the inner circumferential wall of the cam chamber. The movable guide plate, the protruding part, and the inner circumferential wall of the cam chamber together define a combustion chamber.

[0011] A camshaft engine, as in the Fig. The assembly shown comprises: a housing 1, a cam 2, an output shaft 3, a guide plate, a spring 5, an ignition device 6, a gas compression device 7 and an oil supply device 8.

[0012] The interior of the housing 1 is provided with a cam chamber 11, and the cam rotation 2 is located in the cam chamber 11. The cam 2 comprises a rotating part 22 and a projecting part 21. The output shaft 3 is rotatably mounted on the housing 1 and fixedly connected to the rotating part 22, and the projecting part 21 is in contact with the inner circumferential wall of the cam chamber 11.

[0013] The movable guide plate 4 is slidably arranged on the inner circumferential wall of the cam chamber 11 and, under the action of the spring 5, is always in contact with the outer circumferential wall of the cam 2. Furthermore, the projecting part 21 of the cam 2 is also in contact with the inner circumferential wall of the cam chamber 11. Therefore, the movable guide plate 4, the projecting part 21, and the inner circumferential wall of the cam chamber 11 together define a closed combustion chamber 17.

[0014] The ignition device 6 serves to ignite the combustion chamber 17, the gas compression device 7 serves to introduce high-pressure gas into the combustion chamber 17, and the oil supply device 8 serves to inject oil into the combustion chamber 17; the cam chamber 11 is provided with an outlet opening 14. The outlet opening 14 is located on the downstream side of the combustion chamber 17.

[0015] Therefore, when high-pressure gas and fuel oil are ignited and burned in the combustion chamber 17, the high-temperature and high-pressure gas causes the cam 2 to rotate, and the cam 2 then drives the output shaft 3 to rotate, so that the power is transferred to the outside to perform work. As the cam 2 continues to rotate, the exhaust gas in the combustion chamber 17 is discharged to the outside through the outlet opening 14 after the protruding part 21 has bypassed the outlet opening 14.

[0016] In the specific setting as it is in the Fig. As shown, the housing 1 is provided with a guide plate chamber 12, which is connected to the cam chamber 11. Part of the movable guide plate 4 is located in the guide plate chamber 12 and is connected to the spring 5. The other part is located in the cam chamber 11 and contacts the outer circumferential wall of the cam 2, thereby controlling the sliding movement of the movable guide plate 4.

[0017] Furthermore, a roller 41 is provided at one end of the movable guide plate 4 near the outer circumferential wall of the cam 2. The roller 41 contacts the outer circumferential wall of the cam 2 and thereby reduces the friction between the movable guide plate 4 and the cam 2. In addition, the movable guide plate 4 is provided with a lubricating oil passage 42, and the lubricating oil passage 42 is connected to the roller 41, thus helping to direct the lubricating oil to the roller 41 to lubricate it and reduce friction of the roller.

[0018] As in the Fig. As shown, the housing 1 is provided with a transition chamber 13. The transition chamber 13 is located outside the cam chamber 11 and communicates with the combustion chamber 17. The ignition device 6 includes a spark plug. The supply device 8 includes an oil injector. The gas compression device 7 includes an air inlet valve. The transition chamber 13 is provided with an air inlet 15 and an oil inlet 16. The spark plug is located in the transition chamber 13. The oil injector is located at the oil inlet 16. The air inlet valve is located at the air inlet 15. Once the transition chamber 13 is provided, the projecting part 21 of the cam 2 can be prevented from contacting the spark plug, the oil injector, and other components, and from hindering the rotation of the cam 2.

[0019] As in Fig. As shown, the gas compression device 7 comprises a cylinder 71, a piston 72, a connecting rod 73, an eccentric wheel 74, and a drive element. The cylinder 71 adjoins the transition chamber 13. The cylinder 71 is provided with an air inlet valve. A sliding piston 72 is located within the cylinder 71. The drive element and the eccentric 74 are connected. One end of the connecting rod 73 is pivotally connected to the piston 72, and the other end is pivotally connected to the eccentric 74. After the eccentric 74 has rotated, the connecting rod 73 can drive the piston 72 to move back and forth. This achieves the compression of the gas, and the high-pressure gas is directed through the inlet. The air valve vents the transition chamber 13.

[0020] To further improve work efficiency and ensure the engine runs smoothly, as described in the Fig. As shown, the cam 2 is uniformly provided with a number of projections 21 in the circumferential direction. The cam 2 is uniformly provided with a plurality of projecting parts 21 in the circumferential direction. A plurality of movable guide vanes 4 and outlet openings 14, corresponding to the projecting parts 21, are arranged on the cam chamber 11. Several cams 2 are arranged coaxially on the output shaft 3. The projecting part 21 of the plurality of cams 2 is arranged uniformly around the central axis of the output shaft 3 at circumferential intervals. Several cam chambers 11 are arranged on the housing 1, and several cams 2 correspond to each other with a plurality of cam chambers 11.

[0021] This means that a plurality of protruding parts 21 can be arranged on a cam 2, a plurality of cams 2 can be arranged on an output shaft 3, and in order to improve the working efficiency of the engine and to allow the engine to operate smoothly, a plurality of protruding sections 21 should be evenly distributed circumferentially around the central axis of the output shaft 3. Fig. In the structural example shown, a cam 2 is provided with two protruding parts 21, the two protruding parts 21 being arranged radially opposite each other. Two cams 2 are arranged on an output shaft 3 and the two cams 2 are offset by 90 degrees, so that the four protruding parts 21 are evenly spaced circumferentially at 90-degree intervals.

[0022] Similarly, several cam chambers 11 corresponding to the cam 2 are arranged on the housing 1 to allow each projecting part 21 to play a role, a plurality of movable guide plates 4 and outlet openings 14 corresponding to the projecting part 21 are arranged on each cam chamber 11, and the corresponding ratio of movable guide plate 4, outlet opening 14 and projecting part 21 is mentioned above and not repeated.

[0023] In summary, compared to the conventional engine, which performs work through the reciprocating motion of the piston 72, the engine combustion chamber 17 and the gas compression chamber are separate in this scheme, so that the compression ratio and the kinetic combustion energy can be better controlled, can be used effectively, and the efficiency of the combustion chamber can be improved.

[0024] Although some embodiments of the utility model have been shown and described, the person skilled in the art will understand that various changes, modifications and replacements can be made to these embodiments without departing from the principles and purposes of the utility model, and such modifications are within the scope of protection of the claims of the utility model.
