On January 27, 2015, the "China Diesel Engine Industry Association" organized the ""Diesel Engine nitrogen oxides reductant urea aqueous solution manufacturing conditions and product quality supervision and management measures" and CGT mark application application work conference" was held in Beijing. The conference mainly introduced the background and purpose of the "Measures for the Management of Production Conditions and Products Quality of the Urea Aqueous Solution for Diesel Engines with Nitrogen Oxide Reducing Agent," and interpreted the relevant requirements and working procedures stipulated in the implementation rules. The method was organized by the China Internal Combustion Engine Association to compile the “Measures†and was released on November 3, 2014. The formal launch of the CGT logo marks the production and use of automotive urea solutions that have been subject to industry controversy during the implementation of the National IV emissions and quickly entered the normal orbit. With the full implementation of the National IV emission standards on January 1, 2015, the market demand for vehicle urea has soared. For this reason, the convening of the CGT logo and sign management meeting will, to a greater extent, fully prepare the urea solution. The CGT logo sign application and use, vehicle urea production access and certification supervision work specified direction. The first brand of car urea as the automotive carbitol company was invited to attend this meeting. Qin Jian, General Manager, said that strengthening vehicle urea production and manufacturing, product research and development, implementation of quality management, help to effectively regulate the market order, and safeguard the legitimate rights and interests of users It is our unshirkable responsibility that Koran & Co. will firmly establish the strong determination of pollution control. While actively responding to the policy call, we will continue to carry out technological innovations in automotive urea production to enhance our overall strength, establish industry benchmarks, and promote the common development of the industry. And the city is still a blue sky.
