Function analysis of automobile parts in fuel system in auto

In the automobile industry, the fuel system is one of the core components of automobile operation, and its design and performance are directly related to the economy, power and environmental protection of vehicles. This paper will analyze several key components in the fuel system in the automobile manufacturing process, in order to help readers better understand the important role of these components in the automobile working process.

1. Fuel tank: As a space for storing fuel, the design of fuel tank should not only consider the capacity to meet the endurance demand, but also pay attention to safety and corrosion resistance. Modern automobile fuel tanks are mostly made of plastic materials, which have good impact resistance and low cost advantages.

2. Fuel pump: The fuel pump is responsible for pumping fuel from the fuel tank and delivering it to the fuel injector or carburetor under pressure. According to different installation positions, it can be divided into two types: submerged fuel pump and external fuel pump. Efficient and stable fuel pump can ensure that the engine can get sufficient and stable pressure supply, which is very important to improve the performance of the whole vehicle.

3. Filter: In order to prevent impurities from entering the fuel system and causing blockage or other faults, a fuel filter must be set to filter out pollutants such as particulate matter in the oil. Replacing the filter element regularly can keep the fuel flowing smoothly and prolong the service life of related components.

4. Pressure regulating valve: This device is used to control the fuel pressure before and after being delivered to the fuel injector, so as to ensure that it can be maintained in a suitable range no matter how the engine speed changes. The effective management of output pressure is realized by adjusting the opening of the return path.

5. Injection system (including fuel injector): Accurate injection of a certain amount of atomized fuel into the cylinder is a prerequisite for efficient combustion. The application of electronic direct injection technology makes the injection timing and quantity more accurate and controllable, thus improving thermal efficiency and reducing emission pollution.

6. Sensors and control system: With the development of electronic information technology, more and more intelligent sensing components are applied to the fuel management system. For example, information such as oxygen sensor monitoring exhaust gas composition and temperature sensor detecting environmental temperature and humidity changes is fed back to ECU(Engine Control Unit), which makes corresponding decisions to guide the operation process of the whole system after comprehensive analysis.

In a word, in the automobile manufacturing industry, every link of the fuel system is indispensable, and they work together to ensure the power supply needed for the normal running of the automobile. With the rise of new energy vehicle market and technological progress, traditional fuel vehicles are constantly optimized and upgraded, striving to provide better driving experience while saving energy and reducing emissions.
