As a key component of the automobile fuel supply system, the stability of the oil supply pressure and flow control accuracy of the electric fuel pump directly determine the power output and operating efficiency of the engine. It bears the important responsibility of transporting fuel from the fuel tank to the engine. Its performance not only affects the acceleration performance of the car, but also is closely related to fuel economy and emission indicators. It is the core link to ensure the stable operation of the automobile power system.
The working principle of electric fuel pump is based on precise mechanical and electronic coordination. The internal motor drives the impeller to rotate at high speed, sucks the fuel out of the fuel tank under the action of centrifugal force, and stabilizes the oil pressure within a specific range through the pressure regulator to ensure that the fuel is delivered to the fuel injector at a constant pressure. This stable oil supply pressure is the prerequisite for uniform fuel injection of each engine cylinder, which can avoid the sudden strength and weakness of the power caused by oil supply fluctuations, so that the engine is always in a high-efficiency combustion state.
Oil supply pressure and flow rate are the core performance parameters of electric fuel pumps. Insufficient pressure will lead to poor fuel injection atomization and insufficient engine combustion, resulting in a decrease in power and increased fuel consumption; while excessive pressure may aggravate the wear of the fuel injector and increase the engine load. The accuracy of flow control is equally important. It needs to adjust the fuel supply in real time according to the different working conditions of the engine (such as idling, acceleration, high-speed driving), to ensure that the fuel supply is accurately matched with the engine demand, and to achieve a balance between power and economy.
The operating environment of automobiles is complex and changeable, and electric fuel pumps need to have strong durability and environmental adaptability. Its shell is made of oil-resistant, high-temperature-resistant metal or engineering plastic material, which can resist the long-term erosion of fuel oil in the fuel tank; the internal bearing has been specially lubricated to maintain stable operation in high-temperature and vibration environments. At the same time, the built-in filter device can effectively remove impurities in the fuel oil, prevent the blockage of the fuel injector, and extend the service life of the entire fuel system.
With the intelligent and low-carbon development of automobiles, electric fuel pumps are also constantly upgrading. The new product integrates electronic control modules, which can communicate with the engine management system in real time to achieve more accurate oil supply adjustment; the lightweight design reduces its own energy consumption and indirectly improves the fuel economy of the car; the application of noise reduction technology reduces the noise during operation and improves driving comfort. These technical improvements make the electric fuel pump more suitable for the development direction of modern cars while meeting the power needs.
