Yancheng Yancheng diesel exhaust treatment liquid urea solution cars MEP recently released "2013 China Motor Vehicle Pollution Control Annual Report" (hereinafter referred to as the "Annual Report"), announced the 2012 national pollutant in motor vehicles. Report shows that China has become the world's vehicle production and sales for four consecutive years superpower, motor vehicle pollution has become an important source of air pollution is an important cause of haze, smog pollution, motor vehicle pollution control has become increasingly prominent urgency . The official said that China's vehicle sustained growth. Compared with 2011, the national vehicle population increased by 7.8 percent to 223.828 million; wherein auto 108,378,000, 11,450,000 low-speed vehicles, motorcycles and 104 million. Automobile emission standards according to classification, to the country Ⅳ standard and above accounted for 10.1%, the country Ⅲ standard vehicles accounted for 51.5%, the country Ⅱ standard vehicles accounted for 15.7%, the country Ⅰ standard vehicles accounted for 14.9%. The remaining 7.8% of the car has not yet reached the country Ⅰ standard. Press the green flag classification. "Green label cars" accounted for 86.6%, higher emissions, "yellow car" still accounts for 13.4%. Automobile exhaust is one of the major sources of pollution in vehicle exhaust main pollutants HC, CO, NOx and fine particulate matter (PM2.5), a total of more than 670 kinds, after photochemical reaction will produce ground-level ozone and peroxide (both carcinogens). All cars are emissions PM2.5. Automobile exhaust harm PM2.5 mainly in five aspects: First, from 0.04 to 0.1 microns in size, far smaller than 2.5 micron; the second is the toxicity of the chemical composition of large, contain PAHs and nitro-PAHs with and other 16 kinds of highly carcinogenic, and also contains pathogenic substances, toxic and damaging pollutants; third is the number of great, PM2.5 emissions from the current minimum of compressed natural gas (CNG) cars, for example, emissions of 6 × 1011 个 / km, that is, with 600 billion per kilometer emissions PM2.5 particles; fourth is basically no settlement, the presence of long-term accumulation in the air; Fifth, low emission sites, only a few dozen centimeters high, in the person's breathing band, the same amount of pollutants, due to the low emission vehicle parts, body sucked is undiluted high concentration of pollutants, so hazardous to the large number of times, which is different from other types of vehicle exhaust pollution of Pollution key. According to the national air quality real time publishing platform release of key national urban PM2.5 monitoring data - PM2.5 were significantly higher than those of all the city suburb of PM2.5. Large cities in the motor vehicle, the car is an important source of PM2.5. Although the country are carrying out oil upgrade, but the effect is not yet clear. Governance of Enterprise haze has not shirk responsibility for the brightest triumph busy car prices, while not ignoring the development of energy saving push new. Related statistics show that China's new energy vehicle sales nearly 20,000 last year, the growth rate reached 40%. Under the impetus of the policy, China's new energy vehicle sales this year will enter a rapid growth period, reaching 60 000 -15 million. And for the worsening haze, some car prices is well prepared to bring relevant technologies. Guangzhou Toyota pioneered 2.5L4AR-FXE engine is a "hybrid" type hybrid system, and the innovative use Atkinson cycle technology, compared with the same displacement petrol, 100 km combined fuel consumption of 5.3L, reduced by 32%, emissions 66% reduction. Guangzhou Toyota Motor relevant person in charge, "haze rule era", everyone should participate. Environmental protection is not a Konghan slogan, Guangzhou Toyota is currently working to reduce vehicle production process energy consumption and emissions, and ways to reduce reduce product of fuel consumption and pollutant emissions. Shanghai auto show in April last year, Volvo released the "ICE Air Quality Solutions" (including "Air Quality System" IAQS, "clean cockpit" CleanCabin and "harmful emissions" Emission), and promised future models sold in China will be With this solution. Exhaust gas treatment 100 billion to be discovered from the perspective of industry chain, need an automobile engine exhaust gas treatment, oil and exhaust systems of the three simultaneous upgrade. Currently on a global scale, for checking vehicle emissions standards there are three: sulfide, particulate matter (PM) and nitrogen oxides. These three basic environmental protection throughout the car through different steps to resolve, sulfides, mainly through oil upgrading, namely to reduce the sulfur content of the control which the sulfur and olefin content, mainly related to hydrodesulfurization and alkylation more key technologies. The particles need to upgrade the engine combustion system, and can only rely on nitrogen oxide catalytic exhaust system (such as the future of the mainstream of the SCR system and its necessities vehicle urea), three to be synchronized upgrade. Previously, the State Council issued the air control "State 10" display, PM2.5 governance is one of the main content. The industry believes that Beijing's air pollution control as a priority area, "Beijing Clean Air Action Plan 2013-2017" recently released to other parts of the country to carry out related work of guiding significance, motor vehicle exhaust gas treatment will become one of the key air pollution control . Analysts said that with the gradual implementation of the national standard diesel, as well as environmental policy motor vehicle pollution control efforts to upgrade, vehicle exhaust treatment market will heat up. Securities issued research reported, after the implementation of national standards deal with the new diesel engine exhaust can reach market size of about 140-160 billion yuan. It is understood that automobile exhaust gas treatment markets including SCR (Selective Catalytic Reduction) system equipment, automotive urea, automotive catalysts. In heavy card upgrade "national four" standards, for example, a number of brokerage research institutions is expected to bring at least 100 billion market space; and oil upgrade involves a wide range of industrial space involved as much as 100 billion yuan or more.
