Diesel engine emission control standards will soon be introduced

On June 7, 2011, at the Fourth International Symposium on Advanced Diesel Engine Emission Control and Testing and Evaluation Technology, Zhang Kejin, Technical Director of Technical Center of FAW Group, called for the introduction of emission control technology-related materials and process standards as soon as possible to promote the rapid development of technology and application. At the same time, it is stated that FAW is currently developing solid urea emission control technology. Although it has not yet achieved a substantial breakthrough, it has fewer problems than liquid urea. It also proposes to learn from the electric vehicle alliance and form a coalition to jointly advance diesel emission control technology.

Wei Anli, deputy secretary-general of the China Internal Combustion Engine Industry Association, emphasized that traditional car energy-saving is less feasible than electric vehicles because of its relatively small investment, relatively mature technology, and large potential. He believes that the future of passenger car internal combustion engines tends to be miniaturized, miniaturized and dieselized, and various technologies with high power density will be more mature to meet the requirements for energy saving and emission reduction; diesel engines for commercial vehicles tend to be modular and intelligent in their own right. , With the supporting low-cut collaborative development to form a total energy utilization technology.

It is reported that on July 1, 2011, the state-owned diesel emission standard for vehicles will soon begin to be implemented. According to Tang Dagang, director of the motor vehicle emission monitoring center of the Ministry of Environmental Protection, the key to the success of the implementation of the standard is to look at oil prices with sulfur levels below 350ppm during the transition period. Can it be accepted by consumers? At the same time, based on current technological capabilities, there should be no substantial technical barriers for implementing State V, and it is recommended that efforts be made to advance the application of advanced diesel technology. For new vehicles, the principle of implementing the strictest emission standards should be considered when the sulfur content of vehicle fuel allows. .
