On April 3, the reporter learned from the China Society of Automotive Engineers, the Institute organize the preparation of the "car urea solution technical specifications" is officially released this week. The specification is the the highest authoritative standard car with urea field.
It is understood that the car Urea is the development of products with the increasingly stringent emission regulations for heavy-duty diesel vehicles. With the China IV emission standards will be fully implemented, the domestic car started with the urea market, many foreign enterprises, state-owned enterprises, private enterprises have joined the car production and sales of urea. Car the urea quality of the product is good or bad, is directly related to whether the vehicle engine running, Europe, the United States, Japan and other vehicle the urea to develop a complete and mature technology and application specifications. However, after neither car urea national standards, there is no industry standard, only Beijing, Shenzhen, Shanghai, three local standards and requirements of this standard is not uniform. To this end, the industry is an urgent need for a unified technical and application specifications.
In this context, in September 2011, fuel and lubricants branch of the Society of Automotive Engineers of China in Nanjing meeting, agreed by the Jiangsu KLS Automobile Environmental Protection Technology Co., Ltd. and Sinopec's Tianjin Yue Thai Petrochemical Technology Co., Ltd. jointly liable Car the task of preparation of the technical specifications of the products of the urea solution.
According to the report, the technical specifications of the car urea technical indicators, how to use appropriate problem was specified. The specification covers the storage, transport, use, and many other aspects, provides for detection urea content, density, biuret, calcium, iron, copper, zinc, chromium, nickel and 18 indicators, the car with the urea solution storage container material such as austenitic alloy, the PTFE without additives, additive-free polyethylene and polypropylene without additives to make the relevant regulations.
The industry generally believe that the release of the specification to conform to the trend of heavy-duty diesel vehicles State IV emission regulations implemented in a timely manner regulate the urea solution market production standards, scientific, forward-looking and applicability. This standard for vehicle supply, quality supervision, corporate detection of urea solution and the feasibility of providing guidance.
However, the Society of Automotive Engineers of China, the official told reporters, "car the urea solution technical specifications" is not mandatory. The specification is in the car urea solution also no national standards under the premise, according to the car with urea industry has just started, the market share of less than actual, through the maximization of seeking common ground while reserving differences, the formation of a unified technical specification. According to the report, in accordance with the requirements of the Ministry of Environmental Protection, "car urea solution" national standards are being drafted.
