Abstract
Description
Technical Field
[0001] This invention relates to the field of internal combustion engine power equipment technology and discloses a novel design concept for a three-stage high-efficiency and low-emission internal combustion engine. Background Technology
[0002] Currently, traditional internal combustion engines generally adopt a conventional connecting rod piston reciprocating motion structure, with a fixed overall structural layout, low power conversion efficiency, incomplete fuel combustion during operation, and a heavy burden on the exhaust gas treatment system. This not only results in significant energy loss but also easily generates a large amount of exhaust pollutants, leading to poor environmental performance.
[0003] Therefore, the market urgently needs to develop a new type of high-efficiency, low-emission internal combustion engine with a reasonable structural layout, high vacuum utilization rate, excellent power conversion efficiency, and lower emissions, in order to solve the many drawbacks of existing technologies.
[0004] This invention, as a novel internal combustion engine design concept, can significantly improve fuel combustion efficiency and reduce the burden on the exhaust gas treatment system compared to traditional internal combustion engines, making internal combustion engines more efficient and energy-saving. Summary of the Invention
[0005] The three-stage high-efficiency and low-emission internal combustion engine is divided into three sections: upper, middle and lower. The upper section is the camshaft and valves, the middle section is the high-temperature combustion chamber, and the lower section is the crankshaft chamber.
[0006] The upper section is designed as a camshaft and valves.
[0007] The middle section is designed as a high-temperature combustion chamber with a hollow outer wall and a preheating coil and a high-temperature catalytic converter bushing installed inside. This design can increase the temperature inside the combustion chamber when the internal combustion engine is operating.
[0008] The lower section is designed as a crankshaft chamber. This design eliminates the connecting rod piston structure and upgrades to an integrated vacuum plunger structure. The piston and crankshaft are connected via bearings and their components. A sealing guide ring is installed on the inner wall surface of the crankshaft chamber. This design separates the crankshaft chamber and combustion chamber inner wall from the piston, eliminating the need for lubrication. This eliminates concerns about the boiling point and loss of lubricating fluid in the high-temperature combustion chamber during internal combustion engine operation, thus increasing the temperature inside the combustion chamber. A vacuum insulation chamber is fixed to the top of the vacuum-insulated piston, and a heat-insulating sealing gasket is installed between the vacuum insulation chamber and the vacuum-insulated piston. This design isolates the piston from the high temperature of the combustion chamber. The outer wall of the crankshaft chamber is hollow, with coolant channels inside. A vacuum insulation section is added between the coolant channels and the preheating coil. This design provides better cooling for the crankshaft chamber and isolates it from the high temperature of the combustion chamber. The vacuum-insulated piston is connected to the internal combustion engine crankshaft via sliding bearings and their components. A positioning guide slider is installed on the movement trajectory of the bearing assembly on the inner wall of the crankshaft chamber. This slider fixes the movement path of the vacuum-insulated piston, eliminating radial oscillation of the piston, reducing wasted fuel work, and improving the working efficiency of the internal combustion engine.
[0009] Figure Descriptions: In the accompanying drawings, Figure 1 is an overall schematic diagram of the present invention, Figure 2 is a schematic diagram of the overall segmentation of the present invention, and Figure 3 is a labeled diagram of each part of the present invention.
[0010] Engine manufacturing recommendations: ① A traditional engine vortex injector design should be adopted to isolate high temperatures. ② Cylinder head mounting bolts should be designed independently outside the cylinder head body, and the bolts should directly connect the cylinder head and the lower engine block with heat insulation treatment.
[0011] In summary, the three-stage high-efficiency, low-emission internal combustion engine design significantly simplifies the internal structure of internal combustion engines under traditional ideology. By designing the internal combustion engine into upper, middle, and lower stages, and effectively isolating the upper and lower stages from the high-temperature operating environment of the middle stage, the upper limit of the high-temperature combustion chamber's operating temperature can be significantly increased. This helps improve fuel combustion efficiency, effectively reduces the operating load of the exhaust gas treatment system, and significantly improves the overall engine's environmental emission performance.
