What is the high pressure resistance standard of CNG Injector? When designing and manufacturing a CNG Injector, what international or industry standards are usually followed to ensure its high-pressure resistance?
CNG Injector (compressed natural gas injector) high pressure resistance standards will vary depending on the application, vehicle type, engine size and regional safety and environmental regulations. Generally speaking, however, CNG Injectors need to be able to withstand higher pressures because CNG is usually stored in a vehicle's gas tank at high pressure.
When designing and manufacturing CNG Injector, the following international or industry standards are usually followed to ensure its high-pressure resistance performance:
ISO 15500 series of standards: This is a series of international standards for CNG vehicles and their components, including design and testing requirements for CNG injectors. The ISO 15500-11 standard specifically targets CNG injectors and specifies in detail the requirements for their structure, materials, performance testing and evaluation.
SAE J1616 standard: This is a standard for CNG injectors developed by the Society of Automotive Engineers (SAE), covering the requirements for injector design, performance, durability and reliability.
ECE R110 standard: This is the United Nations Economic Commission for Europe (ECE) regulations on compressed gases (such as CNG and LNG) as automotive fuels, which also includes relevant requirements for CNG injectors.
Regional standards and regulations: In addition to the above-mentioned international standards, various countries and regions may also have their own standards and regulations to regulate the design and manufacturing of CNG injectors. These standards and regulations may vary based on local climate conditions, fuel availability, environmental requirements and other factors.
When designing and manufacturing CNG Injectors, manufacturers typically use high-strength, corrosion-resistant materials, such as stainless steel or alloy steel, to ensure they can withstand high pressures and harsh working environments. In addition, manufacturers will also conduct strict pressure tests and durability tests on the injectors to ensure that they can work stably and reliably in actual use.
It should be noted that since the design and manufacture of CNG injectors involves the processing and storage of high-pressure gas, its safety is of paramount importance. Manufacturers need to strictly comply with the requirements of relevant standards and regulations and take effective quality control measures to ensure the quality and safety of their products.
