With the development of the motorcycle industry, the requirements for the efficiency and performance of fuel pumps are increasing day by day.
[0003] Traditional mechanically-driven fuel pumps do not have pressure sensors, temperature monitors, and flow sensors, so they cannot monitor and control temperature, pressure, and flow. Therefore, it is difficult to meet the requirements of modern high-performance motorcycles in terms of efficiency, control accuracy, and response speed. Moreover, the temperature on the surface of the fuel pump is very high. Since there is no heat-resistant material on the surface, it is easy to scald the skin, and the corrosion resistance on the surface is also insufficient. In addition, the fuel pump does not have a filtering structure, resulting in impurities and particles entering the pump, causing internal pollution and preventing them from entering the engine, affecting the normal operation of the fuel system.
