Four discharge standard has been postponed twice diesel countries has formally come into effect on July 1, 2013, due to the standard from the promulgation and implementation of a longer time span, and involve many government departments and enterprises, many of the four diesel emission standards exist some cognitive errors. Provided by reviewing the past policy, five pitfalls of common summarized below, in order to help people to have more clear understanding of these standards.
Myth: four countries indicates four diesel emission standard automotive diesel standards
Vehicle emissions standards and product standards are two concepts we are most easily confused, especially the country's four diesel emissions limits will be in China and three diesel standards and implemented in July 1st, in the face of a large range of focus media, most people tend to be seen as a standard.
China four diesel vehicle emission standards
China four diesel vehicle emissions standards by the State Ministry of environmental protection (hereinafter referred to as the environmental protection department) issued in 2009 01, 05 August, the Ministry of environmental protection issued a notice of solicitation views the implementation of the national emission standards for motor vehicle fourth stage, promulgated the "compression ignition, fuel gas spark ignition engine and automobile exhaust emission limits and measurement methods for vehicle (China III, IV, V stage)" (GB17691-2005) regulations, fourth stage emission of heavy vehicles will be the implementation of the standards in January 1, 2010 control requirements determined (hereinafter referred to as: China four standard).
Then, due to the restriction of technology, cost, because the standard diesel supply is not in place, the four standard has undergone two delay, issued by the State Council in December 29, 2011, according to the "national environmental protection" Twelfth Five Year "plan" and the "Notice of the State Council issued on the" Twelfth Five Year "plan of energy notice" requirements, the Ministry of environmental protection issued four national standards related matters notice, notice that, since July 1, 2013, all production, import, sales and registration of compression ignition engines and cars must meet the four requirements.
In the four car diesel standard
Diesel standards by the State Quality Inspection Administration and the National Standardization Management Committee (hereinafter referred to as the Standards Committee) jointly promulgated and implemented, the implementation of the country's three diesel standards promulgated formally on June 12, 2009, originally scheduled for implementation in January 1, 2010, due to technical reasons delayed to July 1, 2013.
By early 2013 many big mist weather range of stimuli, the central government strengthened energy-saving emission reduction determination, February 6, 2013, executive meeting of the State Council Premier Wen Jiabao presided over the conference decided to speed up the oil quality upgrade. In order to implement the decision of the State Council executive meeting, the State Quality Inspection Administration, the National Standards Committee in February 7, 2013 approved the release of the "diesel (IV)" national standards, to determine from the date of the implementation, the transition period to December 31, 2014, January 1, 2015 formal implementation. Standard set of phase IV vehicle diesel sulfur content is not more than 50ppm. In June 8, 2013, state quality inspection administration, the National Standards Committee and notice, approved the issuance of a "diesel (Ⅴ)" national standard, implemented as of the date of promulgation, the transition period to December 31, 2017. The standard defines fifth stage vehicle diesel sulfur content is not more than 10ppm, the indicators have reached the standard level. In addition, according to the State Council executive meeting arrangements, by the end of 2013, the standard fifth stage vehicle gasoline (sulfur content of no more than 10ppm) will also be releasing the transition period to the end of 2017, the same. It is reported, at present, in addition to Beijing pioneered the use of "Jing five" (the equivalent of "country five") standard oil, Shanghai, Jiangsu, Zhejiang City, Guangdong and other parts to implement "country of four" gasoline standard, other parts of the country is still the implementation of the "country of three" gasoline standard.
Myth 2: four countries indicates four diesel emission standard gasoline vehicles emission standards
The concept of emission standards for diesel and gasoline emission standard is all the more confusing, in 2009 01 months 05 days, in the Ministry of environmental protection issued a notice to solicit opinions of the project implementation of the national emission standards for motor vehicle fourth stage, were referred to the "value and measurement methods for emissions of pollutants from light-duty vehicle Limited (China III, IV stage)" and "automotive compression ignition, fuel gas spark ignition engine and automobile exhaust emission limits and measurement methods (China III, IV, V stage)" provisions, the fourth phase of emission of light and heavy vehicle will respectively in July 1, 2010 and January 1, 2010 since the implementation of the above criteria determine the control requirements.
China four diesel vehicle emission standards
The above has been introduced, China four diesel emission standards promulgated from 2009, through the two delay now will be formally implemented in July 1, 2013.
The country four gasoline vehicle emission standards
Gasoline vehicle emission standard is divided into two parts of light trucks and heavy vehicles, according to the limits and measurement methods for emissions of pollutants from light-duty vehicles to implement "the Ministry of environmental protection issued in June 14, 2011 (China III, IV)" the fourth phase of emission limits announcement, since July 1, 2011, all production, import, sale of light-duty gasoline vehicles, dual fuel the car, a single gas fuel vehicles must comply with the requirements of the standard four. In 2012 07 months 25 days, the Ministry of environmental protection issued the "gasoline engine and automobile exhaust emission limits and methods of measurement of heavy vehicles (China III, IV stage)" the fourth phase of emission limits announcement, notice that, since July 1, 2013, all production, import, sell heavy-duty car sales and registration of gasoline the engine and the vehicle must meet the requirements of the standard in four.
In addition, according to the environmental protection ministry officials, the fifth stages of motor vehicle emission standards, the country five emission standard has gone through all the procedures, will soon be released. The official also said, the standard after the release of not immediate implementation, the implementation of the new standard requires a ready for implementation period, usually the preparation for a period of three to five years. But this standard in the nationwide implementation date is expected to be in January 1, 2018.
Myth 3: national standard indicates local standards
Motor vehicle emissions for the range of label issued usually through years of the transition period will be formally implemented, and the implementation of the preparation period, because the individual local (mainly economic developed area) more serious environmental pollution, energy-saving emission reduction task is heavier, the local government will usually lead to introduction of their respective local standard. In addition, taking into account differences in various places in terms of economic development, city construction and other specific circumstances, the central government will make specific requirements for individual places in the introduction of vehicle emission standards too. Therefore, in real life there will be local and national standard are not fully synchronized situation, which is easy to cause people to misunderstand the emission standard.
According to the current "air pollution prevention law" provisions, the province, autonomous region, municipality directly under the central government for motor vehicles in use the implementation of the new emission standard of air pollutants and its transformation, but must be reported to the State Council for approval.
For example, the Ministry of environmental protection issued in 2009 Notice of solicitation views of the implementation of the national emission standards for motor vehicle fourth stage, to welcome the World Expo 2010, Shanghai city hall first announced the implementation of the fourth phase motor vehicle exhaust emission standards, according to the regulations, from 2009 November onwards, Shanghai city not in conformity with the standard four light-duty gasoline vehicles and public sanitation postal vehicles will not be allowed to hit the road.
In addition, the Ministry of environmental protection issued in December 29, 2011 "automotive compression ignition, fuel gas spark ignition engine and automobile exhaust emission limits and measurement methods (China III, IV, V stage)" the fourth phase of emission limits the notice on the decision to implement the country's four regions, special requirements on the Beijing Shanghai area, regulations Beijing City, Shanghai City, sales and registration for compression ignition engine car, take the lead in the implementation of four national standards for public transport, sanitation and postal purposes, to stop selling and registration does not meet the relevant requirements of the four standard vehicle.
At the beginning of the year Beijing area long-term haze weather also accelerate the implementation of country five emission standard of Beijing city pace, with the approval of the State Council, since February 1, 2013, Beijing is the first city in China began to carry out the fifth stage of the Beijing motor vehicle emission standards equivalent to five standard. To match with the emission standards for oil has also been listed in May 31, 2012.
Myth 4: standard promulgated indicates a formal implementation
Due to the specific conditions of China (motor vehicle emission standards started late), restricted by the oil quality and engine technology and other factors, after the promulgation of motor vehicle emission standards are generally not implemented with immediate effect, therefore the promulgation and implementation of standards, there will be a time difference, which caused some people to mistakenly believe that the implementation of standards promulgated date time.
In fact, when the relevant departments issued a notice of the general motor vehicle emission standards will indicate the specific implementation date, although this date is usually delayed due to various reasons, but will have the time node clear in the notice.
In general, notice issued time for discharge standards promulgated, engine and automobile in the published notice must meet the standards at a point in time before the requirements, and this time point is the implementation date. Usually, standards and implementation will have three to five years of time difference.
Mistake 5: emissions standards indicates the implementation effect
One involves many departments of interest policy promulgated, in the concrete implementation process is often difficult to implement, the vehicle emission standard of course is not exceptional also, emission standard upgrade will inevitably affect the car prices, oil prices, city management and other aspects of the benefit, and this benefit gambling will lead to the implementation effect and the standard is expected to have a huge gap.
In accordance with the provisions of the relevant departments, the current vehicle emission standards nationwide should all meet the country more than three (light-duty gasoline vehicles to achieve four national standards), however, the standard yellow car around the long-standing has exposed the implementation effect of emission standards not just as one wishes.
It is understood, the so-called "yellow label cars" is high polluting vehicles nickname, is not reach the discharge standard of the gasoline vehicle, or does not meet the national III emission standard diesel vehicles, because of the stick is yellow green signs, therefore known as the standard car is yellow, with operating passenger car and truck as the lord.
In June 14, 2013, the State Council Premier Li Keqiang chaired a State Council executive meeting, the deployment of the prevention and control of atmospheric pollution ten measures, the first is particularly stressed the need to enhance the quality of fuel, the deadline for the elimination of yellow car.
In recent years, although the government announced the limit and eliminate the standard yellow cars, but the standard yellow cars is still a huge population, these vehicles because of exhaust emission control technology, has become a major source of pollution of the atmospheric environment.
