On October 20, 2015, the “2015 Heavy Equipment Week†series summit was grandly opened in Beijing. Nearly 200 of the world's leading complete machine manufacturers, engine manufacturers, component suppliers and service providers, more than 300 senior executives from the heavy equipment industry have created an unforgettable business trip for the entire industrial chain of diesel and off-road vehicles. Yuan Ying Yuan Ying of the Environmental Science Research Institute of the Ministry of Environmental Protection of China attended the meeting and gave an in-depth interpretation of the latest emission standards and future development trends of China's diesel engines.
The Law on the Prevention and Control of Atmospheric Pollution was first released in 1987, and the second revision of the recent (August 29) has clearly stated that “the restricted area of ​​high-emission non-road mobile devices†has also been issued for violations of regulations. Detailed disciplinary terms. In contrast, the emission standards for heavy-duty diesel vehicles are constantly improving and strengthening. Yuan Ying pointed out that "the 2005 third, fourth and fifth stage standards have been released, but due to fuel reasons, the implementation of the national four standards has been postponed for two and a half years." As to whether the national five standards can be implemented nationwide in 2017 It is not yet known, mainly because “key areas are implemented ahead of time and only concentrated in urban vehicles. At the same time, due to fuel problems, the possibility of early implementation of passengers and trucks for inter-provincial transportation is relatively smallâ€.
In addition to emission standards, heavy-duty diesel vehicles also have a series of supporting standards. Since the fourth phase, the on-board diagnostic system (OBD), emission control device durability and in-use compliance requirements have been added, and in-vehicle measurement method standards (PEMs) are currently being developed. Yuan Ying said that when the standard was issued, the Euro IV regulations were not yet perfected, so the OBD proposed by the National Standards was only a principle.
In addition, Yuan Ying also elaborated on the detailed formulation of the national six emission standards of concern to the industry. "We will learn the best parts of Europe and the United States, but it is still an important principle in combination with China's national conditions. At the same time, we will continue to significantly reduce NOx and PM emissions, and maximize the use of advanced technologies: DPF, SCR, EGR, etc." In addition, Yuan Ying also said that compared with Euro VI and Euro V, NOx emission control will be tightened by 77% in the national six heavy-duty vehicle emission standards, while PM will be tightened by 67%, and new particulate matter will be added. (PN) limits to facilitate the adoption of DPF technology.
Later, Yuan Ying also gave a detailed explanation and analysis on the issues related to non-road diesel engines and marine engine emission standards, and once improved the atmosphere of discussion and discussion at the conference.
At the Dusit Heavy Equipment Summit with the theme of “Asian Diesel Engine†and “Off-Highway Vehicleâ€, the organizing committee also invited many local government officials and authoritative organization experts to come to the venue to develop the participating enterprises. Difficulties in planning, such as China's Ministry of Industry and Information Technology, Japan Environment Agency, Indian Engine Manufacturers Association, China Construction Machinery Industry Association, China Agricultural Machinery Industry Association, Jinan Automobile Testing Center, Asian Clean Air Center, International Maritime Organization, China Automotive Industry Association.
