According to the announcement of the Ministry of Environmental Protection, from July 1 this year, all commercial vehicles must meet the national IV emission standards. Emissions upgrades for commercial vehicles, especially diesel vehicles, require the upgrading of engine fuel injection systems and the addition of tail gas aftertreatment systems. Li Guoxiang, deputy director of the School of Energy and Power Engineering at Shandong University, believes that this upgrade will not only benefit engine companies, but will also bring new value-added services to vehicle companies, namely tail gas aftertreatment systems.
In the face of the development opportunities brought about by the new standards, many car companies have already planned in advance and want to take advantage of this business opportunity to create new economic growth points. “We have already prepared the production capacity of the National IV product and we have made good arrangements for imported spare parts. The production system has also planned and scheduled production in advance to ensure the supply of the National IV engine after July 1. Meanwhile, the post-processing system independently developed by Weichai Small batches of trucks and buses are assembled in the market, and the market feedback is good.†On April 24, when interviewed by reporters, Guo Shenggang, deputy director of Weichai Power's technical center, introduced.
New standard reduces particulate emissions by 80%
According to the State Council's request, China's total emissions of nitrogen oxides (NOx) from motor vehicles at the end of the "Twelfth Five-Year Plan" are 10% lower than at the end of the "Eleventh Five-Year Plan." However, so far, the total amount of NOx emissions from motor vehicles has not decreased yet.
"Commercial vehicles have the greatest contribution in the exhaust emissions of motor vehicles." Li Guoxiang told the Herald reporter that commercial vehicles mainly use diesel engines. They have long operating mileage and high fuel consumption. The pollutants emitted from the tail gas are mainly particulate matter (PM) and NOx is the main "culprit" of motor vehicle exhaust pollution, and it is also the monitoring focus of emission reduction. According to the data of the Ministry of Environmental Protection, China’s diesel vehicles accounted for only 6.3% of the total vehicle population in 2011, while NOx emissions accounted for 67.2% of the country’s annual NOx emissions, and PM emissions also accounted for total vehicle emissions. 78.8%.
In fact, in order to reduce tail gas pollution from commercial vehicles, the Ministry of Environmental Protection has planned to implement IV emission standards for commercial vehicles nationwide on July 1, 2011 and January 1, 2012. However, due to problems in the company's technical reserves and oil quality, it has repeatedly been postponed. . It is understood that the implementation of the State IV standard diesel engine and the National III standard engine, not only can reduce the fuel consumption of 5% -7%, but also can reduce 80% of PM emissions. From January 1, 2007, Beijing has taken the lead in implementing the National IV emission standards for automobiles. Afterwards, Shanghai and Guangzhou followed suit one after another.
Buy expensive with cheap
As a leader in the internal combustion engine industry, Weichai started to build a National IV engine platform after the successful development of the Blue Engine III engine in 2006. "From State III to State IV, it is not only a simple emission upgrade, but an upgrade of the entire engine platform." Guo Shenggang explained that this includes the strengthening of the engine itself - to withstand higher explosive power, optimization of combustion, through purification Reducing more than 80% of PM emissions also includes increasing after-treatment systems to reduce NOx by more than 35%.
He said that Weichai has successfully developed its own post-processing system. Utilizing the urea supply system, urea is mixed with the exhaust gas of the engine and produces a series of chemical reactions that decompose the harmful substances generated by the combustion of diesel into nitrogen, water and cleanliness. The air thus raises engine emission standards. At the same time, relying on the self-developed post-processing electronic control system, Weichai achieved the match between the entire post-processing system and the vehicle. At present, the Weichai post-processing system has been assembled in small quantities in the truck and passenger car markets, and customer feedback is good.
"Each additional set of post-processing systems for new cars will cost more than 10,000 yuan. However, due to the more fully-burning Chinese IV engines, which is fuel-efficient, this difference will earn more than a year." Guo Shenggang said that the national IV engine power Better sex, better economy, comprehensive savings of more than 5%. From the perspective of fuel economy alone, energy consumption is reduced, which is to reduce emissions. Of course, fuel-efficient for users, more importantly, is to reduce the cost of use. After earning the difference, the later use is the profit earned by the province. Therefore, although the diesel price of the National IV emission standard is high, the use cost is reduced and the user is ultimately the beneficiary.
It is understood that Weichai has specially developed different types and models of post-processing systems according to the needs of different customers, and conducted a large number of vehicle matching tests to meet the vehicle's space layout and weight requirements. For example, Weichai's upgraded version of the Blue Engine Group IV engine and Shaanxi Auto Heavy Truck Co., Ltd. conducted a match test. The engine was upgraded to a 12-litre mature model of Weichai Power's LanQing WP12 series. Through matching tests with Weichai, Shaanxi Auto also completed the technical reserves of the China IV model.
If you are ready to tap business opportunities from the implementation of the National IV emission standards, you will not only get firewood. According to media reports, Bosch CODEC plans to develop the exhaust gas after-treatment system as one of the company's future pillar businesses. By 2014, the exhaust after-treatment system will contribute 560 million yuan in net profit, which is equivalent to the company's full year of 2010. 42% of net profit. Zhongtong Bus also made preparations for product platform adjustments, carried out a catalogue resource reserve for China IV-emitting vehicles, and obtained market access conditions through reporting “announcements†and 3C certification, and at the same time it started to Domestic and foreign markets provide road buses, tourist buses and city buses that comply with State IV emissions.
"Actually, the company's technical reserves are generally well-done, but the market pushes ahead with the oil product." Li Guoxiang believes that the slow pace of oil upgrading has hindered the upgrading of automobile emissions, and the largest oil upgrade Obstacles in cost, how to solve the increase in the cost of oil upgrades require the coordination and balance of interests between the government, oil companies, and auto users.
