Description

Technical Field

[0001] The present invention relates to the technical field of two-stroke engines, in particular to an environmentally friendly hydrogen-powered two-stroke engine. Background Art

[0002] A two-stroke engine, also known as a two-stroke engine, refers to an engine that completes a working cycle in two strokes. In one working cycle, the piston reciprocates two strokes, and the crankshaft rotates one circle to complete the four processes of intake, compression, power generation, and exhaust. Compared with a four-stroke engine, its structure is simpler. A basic two-stroke engine usually has only three moving parts: piston, connecting rod, and crankshaft. There is no camshaft for operating valves to control the flow of combustible mixture or exhaust. It mostly uses air hole ventilation. The exhaust function of existing two-stroke engines is realized by the camshaft. During the rotation of the camshaft, the air will be compressed due to its own shape, and the air will be discharged after leaking out of the exhaust port after the piston moves. However, in this process, the camshaft will lose its rotational power when compressing the air. In addition, the shapes of existing two-stroke engines are different, and the lower side is often not flat, so it is more troublesome to disassemble and repair the engine and it is not easy to place.

The specific schematic diagram of the structure is as follows: Figure 6 The specific function of this structure is to adjust the position of the support frame 1003 relative to the engine body 1.

The second movable groove 13 is fitted with the compressed air outer cylinder 706. The schematic diagram of this structure is as follows: Figure 8 The function of this structure is to drive the driving wheel 9 to rotate through the reciprocating motion of the stroke piston 6. In addition, the second movable groove 13 is fitted with the compressed air outer cylinder 706 to seal the second movable groove 13 during the descending process of the compressed air outer cylinder 706, thereby reducing the possibility of pressure release during the movement.

[0037] Furthermore, a double-headed oil pump 11 is fixedly installed at the center position of the stroke box 2, and the nozzle of the double-headed oil pump 11 is opposite to the upper end of the compressed air inner cylinder 707. This structure allows the contact surface of the compressed air outer cylinder 706 and the compressed air inner cylinder 707 to be additionally lubricated, thereby increasing the stability of the equipment during use.

[0038] Working principle: The engine body 1 of the present invention is provided with the necessary structures of a conventional two-stroke engine, such as a combustion chamber and a crankcase. The raw material burned in the combustion chamber is hydrogen or natural gas supplied by a high-pressure air pump. The high-pressure fuel pump 4 provides a power source for the movement of the stroke piston 6, and the drive wheel 9 is connected to the crankcase. Since it is a commonly used structure, the specific working principle will not be described here. The following is a detailed description of the working process of the exhaust mechanism 7: The compressed air outer cylinder 706 is fixedly connected to the stroke piston 6. The compressed air outer cylinder 706 is a steel cylinder smaller than the piston diameter, and its length is equal to the piston stroke. Depending on the needs, when the two-stroke engine is in working state, the stroke piston 6 moves upward and enters the compression stroke. When the stroke piston 6 moves upward, negative pressure is formed in the space between the stroke piston 6 and the compression piston 708, so that the second exhaust cover 712 moves upward and opens under the action of air pressure, so that the compression inner cylinder 707 and the compression outer cylinder 706 inhale fresh air through the air inlet hole 721. When the stroke piston 6 reaches the top dead center, negative pressure is no longer generated and air intake stops. At the same time, the second exhaust cover 712 on the top of the compression piston 708 automatically closes. The principle of the automatic closing of the second exhaust cover 712 is described below. As described in detail in the text, when the working stroke begins, when the stroke piston 6 moves downward, the air sucked into the compressed air outer cylinder 706 and the compressed air inner cylinder 707 is squeezed, forcing the compressed air piston 708 in the compressed air inner cylinder 707 to move downward, pressing the first spring 709 to the bottom of the compressed air inner cylinder 707, so that the first spring 709 generates a certain potential energy. It should be mentioned that in the normal downward movement process, the air between the stroke piston 6 and the compressed air piston 708 will push open the first exhaust cover 703 and be discharged. However, it is the combustion of hydrogen or natural gas that causes the stroke piston 6 to move downward, and the pressure generated by the combustion of hydrogen or natural gas is generated. The force must be much greater than the pressure required for the first spring 709 to be compressed, so the stroke piston 6 will move down synchronously with the air compressor piston 708. When the piston moves down to 20 mm before the bottom dead point, the exhaust hole 719 leaks out, and the high-pressure gas on the upper side of the stroke piston 6 is discharged from the exhaust hole 719. At this time, the gas on the lower side of the stroke piston 6 will lift the first exhaust cover 703 under the rebound of the first spring 709, so that the fresh air is instantly pressed into the upper side of the stroke piston 6 through the air compressor piston 708 under the action of elastic potential energy, thereby sweeping out the exhaust gas and completing a working cycle.

[0039] The reset principle of the second exhaust cover 712 is that when the second exhaust cover 712 moves upward due to air pressure, the slider 717 moves upward to compress the second spring 718. When the air pressure on the upper and lower sides is close, the second spring 718 will rebound and drive the slider 717 to move downward, thereby causing the second exhaust cover 712 to close the second exhaust groove 710.

[0040] When the support mechanism 10 is needed to support the engine body 1, the screw 1005 is unscrewed so that the screw 1005 is detached from the screw sleeve 1004, so that the support frame 1003 can move between the right-angle blocks 1001. After moving to the appropriate position, the screw 1005 is screwed into the screw sleeve 1004 to fix it.
