April 21, the Chinese Society of Automotive Engineers, the State Council Development Research Center of Industrial Economics Research Department and the China Automotive Technology and Research Center jointly held an international seminar of advanced diesel vehicle technology strategy. At the meeting, the State Department of Environmental Protection Secretary Luo Yi, deputy director of technology standards published \one of the main; clean diesel cars need high-tech high-quality supply of ultra low sulfur diesel. \control, enhance pollution control and diesel cars four major conclusions.
on China's environmental situation, Luo Yi's \the first time both declined over the previous year decreased by 3.14% and 4.66%. saving resources and protecting the environment and more aware of important changes have taken place. gradually improve air quality in cities: in 2007 an average of 113 key environmental protection cities fine gradual increase in the number of days: the ratio of good days 88.7%; compared to 2001 increased by 13.5%; compared with 2001, PM10 concentrations decreased 20%; SO2 reduction 9%; NO2 decreased 2%. \At the same time in the \increase the number of days (and closely related to particulate emissions), acid rain pollution is not reduced; population of more than a million mega-cities, the proportion of low air quality standards; vehicle emissions have become an important source of air pollution in big cities. toxic and hazardous waste treatment delay; economic development and energy demand and control pollution emissions contradictions, rapid growth in coal consumptionreplica watches SO2, dust, dust generation has increased substantially, causing tremendous pressure on the environment. \on the impact of motor vehicles on the environmentreplica watches Luo Yi said: \emissions. urban photochemical pollution problems have become increasingly prominent: motor vehicle emissions of NOx and volatile organic compounds in the atmosphere for further reaction to form a light blue smoke, directly stimulate the respiratory system and cardiovascular system damage. Beijing, Nanning,beijing escort, Shenzhen and other cities have been a photochemical smog. motor vehicle emissions of particulate matter serious harm to human health, urban particulate matter, 20% to 30% from motor vehicle emissions. Department of particulate emissions from motor vehicles can reach the deep lung, more obvious harm to human body. the United States EPA to fine particle emissions from diesel vehicles as one of 189 species are carcinogens. motor vehicle emissions in people's breathing zone height, the more pronounced effect on the human body. \motor vehicle is defined broadly, he said in a statement: \vehicles); on the motorcycle license 87,100,000 (not at least 30 million motorcycles on the license); on road tractors over 14.82 million units. \as farm vehiclesreplica watches these vehicles are basically high pollution, high energy consumption of old diesel vehicles.
\and heating accounts for 10.1%men's swiss watches 4.1% for civilmen's swiss watches transportation accounted for 8men's swiss watch1%. This is Mr. Luo's data have obvious difference.
pollution control measures in respect of motor vehiclesmen's watch Luo Yi in the \reduced to 17 years 5 years now.
The conclusion is: \Lo oyster rolex Deputy Director of the reason is that a significant reduction in cycle emissions, \were further significant reduction of pollutants, CO emission reduction of about 56%, HC emissions reduction of about 50%, NOx emissions reduction of nearly 50%. heavy-duty diesel vehicles: III stage and control stage (stage I,) compared to reducing particulate matter 70%, NOx emissions by 39%; the first phase III and II compared to particulate matter and NOx were reduced by 30%. \The \9.8 liters, 6.2 liters of diesel cars; high-speed conditions, petrol 7.6 liters, 5.1 liters of diesel vehicles. \the majority of diesel vehicles; use of low-cost, fuel consumption savings (about 30%),[转]至今哭项羽 宇太, maintenance cost savings, the owner benefits. HC oyster rolex CO, CO2 emission is low, compared with gasoline to reduce greenhouse gas emissions. \
Clearly, in our case in the energy crisis, Mr Lo did not bury the diesel vehicles in the energy saving advantages. But frankly the same time, Deputy Director Luo said: \perfect. maintenance of diesel vehicles, poor maintenance standards, and the use of harsh conditions, poor vehicle condition aggravated pollution. \: 5.53% of gasoline cars, light duty gasoline vehicles 4.67%, 4.64% medium-sized gasoline vehicle, heavy-duty gasoline vehicles 11.72% rolex watch sale 72.14% heavy-duty diesel vehicles rolex watch sale motorcycles 1.30%. NOx: 38.38% of gasoline cars, light vehicles 11.85% gasoline, medium gasoline vehicles 11.27%, 5.63% heavy duty gasoline vehicles, diesel vehicles 32.63%, 0.23% motorcycle. \weather, the photochemical pollution threat; traffic micro-circulation of air quality is poor; many cities in the high proportion of diesel smoke complaints. \emission standards for diesel vehicles sharing rate of pollution, but the old diesel vehicles, farm vehicles, advanced diesel vehicles, motorcycles and even mixed together.
Deputy Director Luo said: \emission standards for diesel partial song, from the point of emission standards for light diesel vehicles are NOx and particulate matter emissions have been much wider than the gasoline vehicle emission limits required: NOx emissions from gasoline vehicles more than 3 times; particulate matter is actual emissions of gasoline vehicles more than 10 times. \The same situation, so the generation and use of light diesel vehicles will mean more than petrol vehicles emit large quantities of particulate matter and NOx, which is precisely these two pollutants in urban air pollution in China's most serious problem; diesel vehicle emissions that seriously affect the properties health, particulate matter emissions from diesel vehicles contains a variety of carcinogenic substances, which account for a large proportion of PM1 to PM2.5, can enter the human respiratory system through the lungs and blood system, a great impact on human health. around the world have been started to pay attention and take some out measures to control diesel pollution. \there can be no more short-term supply of high quality diesel cars to use, it will be the bottleneck of China's development of diesel cars. \diesel vehicle emission control objectives are: by 2004 the equivalent of the second phase of European emission control standards; to 2008,beijing escort service, and strive to achieve the equivalent level of emission control, Europe's third stage; 2010, after controlling for the level of integration with international emissions. With the diesel engine technology and vehicle development, advanced technology and emissions performance, and achieve national and local emission standards for diesel vehicles should not be discriminatory policy. \\respect, is a high-Systems Engineering: diesel engine, the car itself to greatly improved emission control technology; emission standards, tightening fuel standards to improve; to improve fuel quality, oil refining equipment, to transform, update, the regulatory mechanism should be improved; supervision and management system in the car and the regulations should be strengthened and improved; detection technology and management level have improved. to carry out the country to develop diesel V, VI emission standard: strive to solve the diesel particulate matter, NOx higher issues, with the European V, VI consistent . to promote the further improvement of oil, the oil strict standards for sulfur content, cetane number and other indicators of effective control. strengthen supervision in the car, promoting the city slow down the implementation of diesel vehicles load test method condition . \, China's diesel vehicle emission control levels are relatively low, the pollution problem of diesel cars is still the main cause of urban air pollution; to strictly control diesel particulate matter and nitrogen oxide pollution, the Environmental Protection Department will develop light as soon as possible State diesel vehicles and gasoline V, VI state standards, and gradually the light duty diesel vehicles and light duty gasoline vehicles to perform the same standard limit; the situation of short supply of diesel is still diesel cars in recent years to promote the use one of the main contradictions; clean high technology needs of high-quality diesel cars ultra-low sulfur diesel supply. \
