Internal combustion engines are evaluated based on two main aspects: power performance and economic efficiency. Power performance refers to the engine's ability to generate torque and power, which reflects its energy conversion capability. Key parameters for this include torque and power output. On the other hand, economic performance measures how much fuel is consumed to produce a certain amount of power, indicating the quality of the energy conversion process. Thermal efficiency and fuel consumption rate are the primary indicators of economic performance.
Looking ahead, the development of internal combustion engines will focus on improving combustion processes, increasing mechanical efficiency, reducing heat loss, and lowering fuel consumption. Researchers are also working on alternative fuels to diversify energy sources, reduce harmful emissions, and minimize noise and vibration. High-pressure technologies will be used to enhance engine power, while composite and adiabatic turbo compound engines will be developed. Microprocessor-based control systems will optimize engine operation, and structural improvements will increase reliability and longevity. Innovations like variable valve timing, lift, and cylinder deactivation are being explored to improve performance and efficiency.
This unique engine features a barrel-shaped cylinder with a central hole at the bottom. A shaft passes through the center, similar to a chopstick inserted into a thick cake. The shaft extends through the hole in the barrel’s base, and the cake becomes part of the closed cylinder cavity. The volume of the chamber can be adjusted by moving the shaft using mechanical or hydraulic methods.
The bottom of the barrel has a cut from the edge of the central hole to the inner wall, where a rectangular plate is inserted. Similarly, the cake’s surface is cut from the outer edge to the shaft, and another rectangular plate is placed there. These plates divide the cylinder chamber into two sealed sections: one for high-pressure gas or an oil-gas mixture, and the other for exhaust. By rotating the plates, the engine can cycle between compression, combustion, and exhaust phases.
During operation, the first sealed chamber is filled with high-pressure gas and expands as the engine rotates, creating rotational force. As pressure decreases, the second chamber vents, allowing fresh air to enter. This cycle continues, maintaining efficient combustion and energy conversion.
To manage the movement of the plates, curved channels are engraved into the barrel and the shaft. Sliding blocks connect these channels to the rectangular plates, controlling their movement as the engine operates. The design ensures that the plates remain in contact with the inner surfaces, preventing misalignment or damage.
This engine converts the internal energy of high-pressure gas into kinetic energy along a curved path, making it a dynamic mechanical device. It can also function in reverse, acting as a compressor or brake. When combined with ignition systems, it can convert large amounts of high-temperature, high-pressure gas into usable mechanical energy, making it a highly efficient power source.
The engine’s operation follows an arc-like trajectory, allowing for continuous adjustment of displacement. This flexibility enables better adaptation to different loads and speeds. Multiple sets of plates and cylinders can be arranged to reduce stress on the shaft, lower noise levels, and ensure stable power output. By minimizing residual pressure discharge, the engine can operate under optimal conditions, making it ideal for energy-saving applications.
Unlike traditional steam engines, piston engines, or delta rotor engines, this design is known as a "variable capacitive arc cylinder engine," offering a new approach to internal combustion technology.
Laboratory Centrifuge
A laboratory centrifuge is a piece of equipment used to separate components of a mixture based on their density and size. It works by spinning samples at high speeds, which creates a centrifugal force that causes the heavier components to move to the bottom of the tube or container. The lighter components remain at the top or in the supernatant.
Laboratory centrifuges are used in various fields such as biology, chemistry, and medicine. They can be used for DNA extraction, protein purification, cell separation, and blood analysis. They are essential tools in research and diagnostic laboratories.
