in order to implement the 12th Five year plan for energy conservation and emission reduction and the action plan for air pollution prevention and control, promote the prevention and control of air pollution and reduce vehicle exhaust emissions, the Ministry of industry and information technology will fully implement the emission standards of the fourth national standard from January 1 next year

however, a few drivers in the market shut down the SCR system of the vehicle, "so he is cutting corners, but the harm is very huge, not only damaging his vehicle, but also making the national emission standard No. 4 unable to achieve the expected goal, which will make the efforts of government departments to control smog come to naught." Said Chen Xiaoxing, marketing director of Jiangsu Longpan Technology Co., Ltd

the national four standards for commercial vehicles will be officially implemented next year

the official implementation of the national four standards means that the approval of the new vehicle announcement catalogue of the national three emission standards will end at the end of this year, and the sales of vehicles with the national three emission standards will also end at the end of this year

however, from country 3 to country 4, it is estimated that the cost of medium-sized vehicles will increase by 20000-30000 yuan, and the cost of heavy trucks will increase by 30000-40000 yuan. The larger and heavier the vehicle, the higher the cost to be increased

"at present, our diesel commercial vehicle manufacturers generally use selective catalytic reduction (SCR) technology to treat the nitrogen oxides in the tail gas by using urea solution in the technical scheme from the third to the fourth of the country. Therefore, after adding these equipment, the cost will rise, and the cost of a medium and heavy-duty truck costing hundreds of thousands will rise by about 10%." Ren Diansheng, deputy director of FAW Jiefang Qingdao automobile factory, said

because of this, during the national two sessions this year, Yan Ping, chairman of the board of directors of Guangxi Yuchai Machinery Group and chairman of Guangxi Yuchai Machinery Co., Ltd., proposed that the state give subsidies to truck enterprises, In order to offset the design of the host and auxiliary equipment of the experimental machine brought about by the implementation of the fourth national standard, the advanced technology cost of foreign countries has increased

"in particular, most of the products of the third country of medium and heavy trucks are mechanical pumps. The real implementation of the fourth country will face the cost pressure of switching the electronic fuel injection system and increasing the exhaust after treatment system. Engine plants and vehicle plants are facing huge cost pressure." Yan Ping believes that "if there is no subsidy, the increase in costs will eventually be passed on to consumers, resulting in the increase in freight rates, which will affect all aspects of economic activities and the level of prices."

"in fact, as early as two years ago, the state intended to implement the National IV emission standard for diesel engines nationwide. However, the reason for pushing it again and again was that at that time, many commercial vehicle manufacturers could not meet the exhaust gas treatment technology, and it was difficult to upgrade the technology." Tang gonggou, director of the motor vehicle emission monitoring center of the Ministry of environmental protection, said

it is understood that the fourth national emission standard was originally planned to be implemented on January 1, 2011, but on December 21, 2010, the environmental protection department said that the implementation time of the fourth national standard for diesel oil with more than 3.5 tons would be postponed for one year, that is, to January 1, 2012. However, due to some reasons, the fourth national standard was postponed again and officially implemented on July 1st, 2013. However, on the eve of implementation, the Ministry of environmental protection reached an agreement with the Ministry of industry and information technology and industry associations on the implementation time of the fourth national standard, and the fourth national emission standard for heavy-duty diesel vehicles, which was originally scheduled to be officially implemented on July 1, 2013, was postponed again

however, Premier Li Keqiang previously made it clear in the government work report that the national four standard vehicle diesel will be supplied nationwide in 2014, releasing the signal that "there is no room for environmental protection standards", which will accelerate the process of implementing the national four standards in all regions

high cost, the implementation of the four national standards "stands in the way"

in the past, the haze in Beijing began in November every year, and now it has been advanced to October. Nitrogen oxide is the precursor of PM2.5 and ozone in the atmosphere, which is not only one of the causes of haze, but also can induce luminescence chemical pollution. Under the action of catalyst, vehicle urea solution can decompose the nitrogen oxide emitted by diesel vehicles into environmentally friendly nitrogen and water, which can fully reduce the nitrogen oxide emission of diesel vehicles. This means that from the perspective of the mechanism of reducing vehicle exhaust emissions, vehicle urea solution is the most effective product to control nitrogen oxide pollution in diesel vehicles

in fact, from a worldwide perspective, the technical route of heavy truck country IV upgrading includes both SCR and EGR. It is understood that in Europe, most truck enterprises choose SCR as the mainstream national fourth upgrading technology route; In the United States, egr+doc+dpf technology is mainly selected. The reason why most European manufacturers choose SCR to meet the Euro 4 and Euro 5 emission standards is mainly due to cost considerations. The fuel price in Europe is relatively high, and the better fuel economy of SCR makes this technology the first choice. Chinese heavy truck enterprises mainly choose s3 After the power supply returns to normal, the CR technical route is based on China's national conditions

insiders pointed out that generally speaking, SCR has small changes to the engine, good engine durability, good fuel economy, low requirements for fuel oil and engine oil quality, no risk of catalyst blockage, good continuity of technical upgrading, no need for fuel injection regeneration control device, and low use and maintenance costs for the engine. However, the SCR system needs to add urea injection system, and the requirements for packaging are relatively high. SCR system needs to solve the problem of urea supply first. For the passive regeneration system, the fuel consumption of egr+doc+dpf is high, so the E-GR and its cooling system need to be increased, the fuel with ultra-low sulfur content and high-quality lubricating oil are required, and the maintenance requirements for the engine itself and post-treatment are high, otherwise the service life of the engine will be affected and the risk of catalyst blockage may be caused, and the continuous upgrading of technology is poor

however, the passive regeneration system does not need to add urea injection system, and the requirements for packaging are low. For the active regeneration system, in addition to meeting the requirements of the passive regeneration system, it also needs to add fuel injection regeneration devices and make more complex calibration, which increases the development cost and calibration difficulty. Egr+doc+dpf system should first solve the problem of low sulfur diesel supply and complex system calibration nationwide. The adoption of SCR technology route by China's mainstream heavy truck enterprises is mainly based on the actual national conditions such as technical capacity and oil product status

"vehicle urea solution is the key to solving vehicle exhaust pollution in haze pollution. It is a necessary consumable solution for vehicles to control NOx Exhaust emissions. The consumption during vehicle driving is 5% of fuel." Chen Xiaoxing told the author

however, due to the increase in costs, it is difficult for many consumers to accept it for the moment. At present, the dealers in the four regions of the country have fallen into the embarrassing situation of "no one buys it in the fourth country, and a person in charge of a polyurethane insulation material enterprise told:" the consumption of polyurethane insulation materials has increased significantly this year, and the third country cannot sell it ". Among the upgrading costs of national fourth truck, vehicle urea also occupies a place. This new cost to car owners is also a matter of concern in the industry

how to treat the cost increase caused by vehicle urea? A person in charge of the enterprise said, "the annual use cost of domestic vehicle urea solution is not low. And the country currently has no special subsidies for vehicle urea, so this is not a small cost expenditure for the majority of users."

that's why, "before the implementation of the National IV standard, the method of avoiding exhaust emission detection without urea has appeared in the market, which has been strictly prohibited in foreign countries." Chen Xiaoxing said, "we call for attention and hope that the whole society will pay attention to this phenomenon, and hope that this emerging market can be strictly supervised."

insiders pointed out: "From the macro level, upgrading the national four emission standards is a major event related to human development. The majority of diesel vehicle users need to establish a correct attitude and treat the problem of the increase in the cost and price of national four products rationally. The most important thing is that vehicle enterprises and supporting enterprises should make joint efforts to minimize the price pressure of end-users, and balance the environmental protection and the benefit of the people to achieve a satisfactory result for consumers."
