At the beginning of the new year, the diesel fuel dispensers in Ningbo, Taizhou, Wenzhou and other places have been replaced with the National IV mark. So far, the diesel fuel in the province's gas stations has been fully upgraded to the National IV standard.
From the main channel of Zhejiang oil supply, Sinopec Zhejiang Petroleum Branch can understand that as early as the beginning of 2014, the company began to actively upgrade the diesel to the national IV standard preparation work, plan to replace as early as possible, and overcome the technology and cost. Difficulties in resources, transportation, storage and transportation, the first phase began to supply the national IV standard vehicle diesel in Hangzhou in mid-September last year, and the National IV standard vehicle diesel in Hangzhou-Jiaxing-Huzhou area was upgraded on November 1.
Since the New Year's Day, the province's gas stations including Sinopec will supply the full range of national IV standard vehicle diesel.
Emissions of large diesel vehicles Heavy-duty diesel vehicles with black smoke can be said to be the largest emitters in the car.
However, because there are few diesel vehicles in general household vehicles, the oil standard problems and emission problems of diesel vehicles are relatively small.
Wu Jian, director of the Atmospheric Office of the Zhejiang Academy of Environmental Sciences, told reporters that only 17% of the diesel vehicles in China have a nitrogen oxide emissions of 67.2% and particulate matter of over 90%.
Nitrogen oxides and particulate matter are the culprit in the formation of haze and photochemical smog.
According to the Traffic Management Bureau of the Zhejiang Provincial Public Security Bureau, as of the end of February 2014, the number of motor vehicles in Hangzhou reached 2.598 million, of which more than 230,000 diesel vehicles, but only less than 10% of the diesel vehicles were discharged. Nitrogen oxides account for more than 70% of the nitrogen oxide emissions of motor vehicles in Hangzhou. In other words, compared with the small-displacement, well-equipped family cars owned by Hangzhou citizens, large-displacement diesel buses and heavy-duty diesel trucks, because of low oil standards and old equipment, almost arranged for Hangzhou. 70% of the city's automobile exhaust pollution.
National IV diesel, sulfur content will drop by 85%
Greener and more environmentally friendly As people's awareness of environmental protection gradually increases, the air quality indicators represented by PM2.5 are also highly valued by the public. Vehicles and oil products naturally enter people's field of vision, while paying attention to oil prices, the voice of oil upgrading It has been very high.
In particular, the province has a large car ownership, and how to effectively control vehicle emissions has been concerned by the government and the public.
According to the requirements of the state, according to the "Special Implementation Plan of the Action Plan for Air Pollution Prevention and Control in Zhejiang Province", starting from January 1, 2015, all gas stations in the province will realize the supply of national IV standard vehicle diesel.
According to public information, the environmental performance of China IV vehicle diesel is superior to that of the original National III vehicle diesel, and the emission reduction is obvious. Sulfur content is the most critical quality indicator in automotive diesel.
Compared with the national III vehicle diesel, the sulfur content of the national IV vehicle diesel oil has dropped from 350ppm to 50ppm, a significant drop of 85.7%.
According to the calculation of Zhejiang's consumption of 9.5 million tons of diesel in 2013, after the upgrade of this round, Zhejiang can reduce sulfur emissions by 2,850 tons throughout the year, contributing a lot to environmental improvement.
At the same time, the diesel fuel of the national IV emission standard is filled with the diesel fuel of the national IV, and the diesel exhaust gas treatment liquid needs to be added according to the national regulations to reduce the emission of harmful components in the exhaust gas.
The use of exhaust gas treatment can reduce 90% of nitrogen oxides and 80% of particulate matter in diesel exhaust. Therefore, through this round of oil upgrades, as well as the use of corresponding emission standards and supporting means, will provide new and powerful support for environmental improvement and protection in our province.
The price has changed. It is worth paying attention to consumers. After this upgrade, according to the oil price reduction information released by the Zhejiang Provincial Price Bureau on December 26 last year, except for the Hangzhou-Jiaxing-Huzhou area, the price has been changed in advance, and the other regions in our province are 0#. The price of IV diesel oil was changed to 5.72 yuan / liter, and the price of -10 #国IV vehicle diesel was changed to 6.06 yuan / liter.
After the upgrade of the National IV vehicle diesel, the label will remain unchanged. During the replacement period, the national IV and the national III standard vehicle diesel can be mixed and filled.
However, the reporter learned from Sinopec that consumers who hold fuel cards in our province, if they set up value-added services such as limiting the type of oil filling, need to go to the nearest gas station or fuel card business outlets to make corresponding changes.
In addition, due to environmental considerations, with the completion of this round of National IV vehicle diesel upgrades, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection have also issued relevant regulations, China will implement national IV emission standards for diesel vehicles.
Good cars use good oil, not only diesel upgrades, diesel fuel emission standards will be upgraded accordingly. National III standard (engine) diesel vehicles will not be sold and registered.
