The emission standards for fuel pumps and injectors vary in different regions, and the following are some of the main situations in these regions:
Europe: European emission standards are relatively strict and have now been implemented to Euro 6 standards. Starting from the Euro III standard, it is required to use an electronic fuel injection system to achieve more precise control of fuel injection quantity and timing. With the upgrading of emission standards, the requirements for fuel injection pressure are constantly increasing. Under the Euro 6 standard, the fuel injection pressure usually needs to reach 2000 bar or more to ensure full atomization and combustion of fuel and reduce pollutant emissions. At the same time, it is also required that the fuel pump and injector have good sealing and reliability to prevent excessive emissions caused by fuel leaks and malfunctions.
United States: The emission standards in the United States are also very strict, and California's emission standards are among the strictest in the world. The requirements of the United States for fuel pump injectors include precise fuel metering and injection control to meet emission requirements under different operating conditions. There are strict limits on reducing nitrogen oxide (NOx) and particulate matter (PM) emissions, and advanced emission after treatment systems such as selective catalytic reduction (SCR) systems and particulate matter filters (DPF) are usually required. This requires a good match between the fuel pump injector and the after treatment system to ensure the efficient operation of the entire emission control system.
Asia: Japan also has strict emission requirements for fuel pumps and injectors, emphasizing fuel economy and low emissions. Its emission standards require the fuel injection system to achieve high-precision fuel injection control to reduce harmful gas emissions. For example, by adopting advanced electronic control technology and fuel injector design, fuel can be fully burned in the combustion chamber, reducing the generation of pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). South Korea's emission standards are in line with international standards, and the requirements for fuel pumps and injectors are constantly increasing. While controlling emissions, attention is also paid to the durability and reliability of products. Starting from July 1, 2021, China has implemented the National VI emission standard for heavy-duty diesel vehicles, requiring fuel pumps and injectors to have higher injection pressure, more precise injection control, and better sealing to meet the strict emission limits for pollutants such as nitrogen oxides and particulate matter under the National VI standard.
In addition, when exporting fuel pumps and injectors, companies also need to pay attention to local certification requirements, such as CE certification from the European Union and SIRIM certification from Malaysia, and ensure that the products comply with relevant standards.
