Description

Technical Field

[0001] The swing-type internal combustion engine used in ordinary vehicles is characterized by its smooth operation and high speed. Background Technology

[0002] With the trend of electrification replacing oil and gas engines, new energy vehicles occupy a large market share, but pure electric vehicles rely on high-power charging piles and fast-charging battery packs, which also drives up costs.

[0003] For vehicles that operate for long periods and have short downtime periods, and for which charging is inconvenient, an engine is a suitable choice.

[0004] The four-stroke internal combustion engine commonly used today has the disadvantage of large vibrations due to the reciprocating motion of the piston.

[0005] To provide an alternative operating option, while utilizing existing oil and gas supply facilities, a connecting rod is used as a variable displacement component. This connecting rod operates in a swinging manner, converting the gas combustion and expansion into torque, reducing vibration and increasing engine speed. This reduces vibration caused by operation, increases engine speed, and features high speed, stability, and low noise. Summary of the Invention

[0006] Compared to traditional piston engines, the piston, cylinder liner, intake valve and exhaust valve train are eliminated, and the main shaft eccentric connecting rod and cylinder block are used directly as variable displacement cylinder block, reducing the number of parts.

[0007] It adopts a modular design, with compressed air as a separate module that handles both intake and air compression.

[0008] Compressed air, liquefied gas, or liquid fuel spray is sent into the cavity, ignited by a spark plug, and the gas expands, pushing the connecting rod to swing, the cavity becomes larger, and drives the main shaft to rotate to complete the work. One rotation completes one power stroke, and exhaust gas is swept away on the other side of the connecting rod at the same time. Attached Figure Description

Note: Figure 3 and Figure 4 It is a micro-clearance fit part, and the height of the eccentric cylinder is no greater than the height of the connecting rod ring. Figure 3It's a model with a small ring height. Figure 4 It is another model with a larger eccentric cylinder height.

[0013] Figure 5 This is a side view with the axis at 0 degrees. Note: The positions of the air intake, fuel injector, spark plug, and exhaust port are not shown.

[0014] Figure 6 This shows the position of the shaft rotated 60 degrees;

[0015] Figure 7 This shows the position of the shaft after rotating 180 degrees;

[0016] Figure 8 The image shows the position of the shaft rotated 300 degrees. Detailed Implementation

[0017] The intake and compression are completed by an external module. The main shaft (3) rotates about 10 degrees, the nozzle (7) sends in high-pressure gas, the main shaft rotates about 15 degrees, the fuel injector (8) injects fuel, the main shaft rotates about 20 degrees, the spark plug (9) ignites, the gas expands and does work, the main shaft rotates to about 300 degrees and reaches the exhaust port (4), and begins to discharge exhaust gas. One rotation completes one work cycle.

[0018] Exhaust gas can be discharged throughout the entire cycle. By monitoring the shaft angle position through sensors, the control system controls the timing and various quantities of air intake, fuel injection (gas combustion), and ignition to obtain different amounts of torque and speed, adapting to different environments and usage habits.

[0019] Cooling can be achieved by liquid cooling, depending on the engine size and operating environment. The housing is hollow and can be filled with coolant or oil cooling, or it can be configured as an air-cooled external heat sink.

[0020] For lubrication, appropriate spaces are left in the eccentric circular spindle and connecting rod to store lubricating oil. Lubricating oil can also be stored at the end of the connecting rod, and an internal circulation device can be added.

[0021] For sealing, rubber ring seals are installed in circular grooves in the cylinder block shaft hole and cylinder head shaft hole, and the cylinder block and cylinder head are sealed with rubber rings.

[0022] Use lightweight, high-strength, high-temperature resistant and wear-resistant materials.

[0023] The schematic diagram shown is for a single-cylinder structure, which can be increased to two, three, or more cylinders. The actual structure, shape, and internal circuitry will vary depending on the size, eccentricity, cooling method, lubrication circuit, seals, and model. Cooling and lubrication will also differ between horizontal and vertical placements.
