A few days ago, the Ministry of Environmental Protection announced for the first time the emission data of motor vehicle pollutants in China. The data showed that for the first time in 2009, China became the world’s largest automobile production and sales country. The country’s motor vehicles emit 54.433 million tons of pollutants, and the exhaust emissions of motor vehicles have become large and medium-sized cities in China. The main source of air pollution. In the face of the National IV emission standards that will be launched next year, many people have doubts about the suitability of vehicle oil.
The amount of ownership is not directly proportional to the emission standards. In 2009, the country’s auto production and sales volume reached 13.791 million vehicles and 13.634 million vehicles, an increase of 48.3% and 46.2% year-on-year, and the number of motor vehicles was close to 170 million, an increase of 9.3% year-on-year. According to the classification of auto emission control, cars that have reached the national III or above emission standard account for 25.4% of the total vehicle ownership, State II cars account for 31.8%, State I cars account for 25.7%, and the remaining 17.1% of the cars still do not reach the national I. Emission Standards. With the increase in the number of motor vehicles, the impact of motor vehicle emissions on the environment is becoming increasingly serious. Environmental monitoring in 2009 showed that one-third of the 113 major environmental protection cities in the country did not meet the standards for air quality.
The Ministry of Environmental Protection, which implements the "National IV" standard next year, said that at present, most of China's light vehicles use the National III standard, and the national IV emission standard will be launched nationwide next year.
It is understood that countries such as the European Union have included carbon emissions from vehicles into the standard system, and China may include this item in the National IV standard. In this regard, relevant experts stated that the National III and the National IV standards refer to the Euro III and Euro IV automobile emission standards. Compared with the National I-II, the National IV has further reduced the pollutant discharge limit and the national III standard of exhaust pollutants. The emission limit is reduced by 30% compared to the national II standard tail gas pollutant emission limit, and the national IV standard will be further reduced by 60%.
The product technology is basically mature. Yue Renren, president of Sichuan Automobile Industry Association, told reporters that at present, China's national IV emission standard heavy-duty diesel engine products and exhaust gas after-treatment device technology have basically matured, light and heavy-duty gasoline vehicle manufacturers, fuel injection systems and exhaust gas aftertreatment The products, technologies and production capacity of key component manufacturers, such as systems, can also meet market demand.
Luo Kaijun, an expert in vehicle maintenance, said that the technology of fuel injection systems and turbocharging systems is mature, but the preparation of exhaust gas aftertreatment devices is not yet adequate. Currently, only small batches of products can be supplied to OEMs for matching and R&D work.
Impact of vehicle oil mismatch effect Next year, China will start the national IV emission standard. One vehicle that meets the national IV emission standard will be reduced by about 50% compared with the pollutant emission of the same type III vehicle. Comparing with the speed of the "escape" of this motor vehicle emission standard, China's fuel quality and national standards have been slow.
“Since the implementation of State II emission standards in China, fuel quality cannot guarantee the implementation of emission standards. In 2008, the national motor vehicle emission standards have been upgraded to State III, but until January of this year, the national city vehicle gasoline was required to meet the national III standard. "Yue Youren said that next year we must implement the National IV emission standards. If fuel can't keep up, then it's still empty talk.
Sichuan Provincial Environmental Science Research Experts pointed out in this regard: “The requirements for fuel for vehicles and fuel additives for automobiles are too general, resulting in a mismatch between the current emission standards and the vehicle fuel standards, and affecting the emission control of motor vehicles. Actual results.†In the future, the regulation of fuel quality and vehicle emissions will occur simultaneously rather than separately.
