Brief: The Brazilian market has a high use rate for new fuels such as clean fuels and biofuels. The use of compressed natural gas CNG as a fuel for automobiles has many advantages, including lower costs, because the fuel is cleaner and the engine life is extended and the maintenance cycle is longer. The oil change cycle becomes longer, and the initial modification is more convenient. In addition, since the natural gas density is lower than the atmosphere, it can diffuse rapidly during leakage, reducing the chance of accumulation and deflagration.
The automotive CNG fuel system has a high working pressure and its related safety standards are also relatively high. Running vehicles in Brazil requires two inspections per year and one test every five years. The relevant parts also need to be certified according to INMETRO Ordinance No. 111.
INMETRO-certified parts for CNG fuel systems include: check valves, manual valves, manual cylinder valves, automatic valves, gas injectors, pressure indicators, pressure regulators, gas flow regulators, mixers, pressure relief valves , pressure relief device, restrictor valve, sealed housing, fuel pipe, fuel hose, filter, interface fittings.
The test items of INMETRO Ordinance No.233 for CNG fuel system components include: hydraulic strength test, air tightness test, over-torque test, bending moment test, continuous operation test, corrosion resistance test, oxidation resistance test, electrical overpressure test, soaking Test, vibration test, compatibility test of brass materials, etc.
ATIC is the authorized organization of the Brazilian certification agency CATA|A2br in China, responsible for the CMA|A2br factory audit, sampling and product testing of INMETRO certification in China. The scope of authorization includes: LED light source, auto parts, pressure vessels, household appliances, building structures.
INMETRO (National Institute of Metrology, Standardization and Industrial Quality), the Brazilian Ministry of Metrology, Standardization and Industrial Quality, is a government department directly under the Ministry of Development, Industry and Foreign Trade of Brazil. INMETRO's product range includes home appliances, medical devices, automotive parts, LED light sources, pressure vessels, etc. With the enactment of more new regulations and implementation rules, more and more products are included in the INMETRO mandatory certification.
