Beijing five implementation of the market trend into the unknown

Recently, Beijing issued "Beijing 2013-2017 clean air action plan focused on the task decomposition in 2015 measures", which explicitly states that before the end of the year, new heavy duty diesel car full implementation of the fifth stage of emission standards, non-compliance of the vehicle shall not be sales in Beijing and registration. This is in March 1, 2013, Beijing officially implemented motor vehicle emissions standards after Beijing five, the first clear the specific implementation of the standard of heavy diesel engine Beijing five emission standards. The news, immediately aroused great concern from all walks of life.

Beijing emissions and then upgrade to the environment

According to relevant reports show that 2014, Beijing sulfur dioxide, nitrogen oxides reduction for 10 years maximum, an average reduction of more than 7%, PM2.5 concentrations fell 4%. Among them, one (excellent) days reached 93 days, 22 days more than that in 2013, an increase of up to 31% and PM2.5 heavy pollution days for 45 days, decrease 13 days than in 2013, a decline of 22 percent.

Through the above data can be seen, after a series of environmental initiatives, Beijing air pollution control initial success.

"In recent years, we have clearly felt the government of Beijing to improve the efforts of the atmosphere environment." Beijing Hongxin auto sales & Service Co., Ltd., deputy general manager of Kincaid on the commercial Automotive News "reporter said:" in our auto industry as an example, in order to effectively control the automobile exhaust emission repeatedly upgrade in advance emission regulations, higher emissions standard implementation provides a strong support for the governance of air pollution in Beijing. "

As the dealer said, the results achieved in the Beijing air pollution control is part of the high standards of emissions before the implementation of the high standards of domestic emissions regulations. Today, in order to have a better control of the atmosphere in the next stage, to the public will be able to see more blue sky, Beijing will before the end of this year formally implemented the fifth stage of the heavy-duty diesel vehicle emission standards is often said that the "Beijing five" emission standards, once again walk in the forefront of the country.

"Beijing ahead of other regions to implement the fifth stage emission regulations in heavy-duty diesel vehicles, basic to be expected, because in recent years the area emissions regulations for the implementation of the specific time can be seen, Beijing always walk in the forefront of the country, which with Beijing as the political center of the country, need to play a leading role are not unrelated. Of course, the environment pollution is serious, the situation is forced to enter the fifth phase of the first heavy diesel vehicles in Beijing emissions regulations one of the main reasons. Guangxi Yuchai machine Limited by Share Ltd deputy general manager Zhong Yuwei told reporters.

And Yu Wei Zhong to the same ideas and State Key Laboratory of vice director Yao Chunde of engines of Tianjin University, he pointed out that, Beijing took the lead in the implementation of heavy-duty diesel vehicles on the fifth stage emission regulation significance is greater than the actual effect.

"The air pollution serious threat to the health of the health of the people in Beijing and the surrounding people, the implementation of the fifth phase of heavy diesel vehicles can improve the atmospheric environment earlier. In addition, Beijing, after all, is the capital. Need to take the lead, set an example, for the future nationwide implementation of the emission regulations in five directions, ahead of the implementation of the fifth stage of heavy-duty diesel vehicle emission standards in the reason. " Yao Chunde said.

Beijing five R & D difficulty

And January 1, 2011 already in Beijing implementation of heavy-duty diesel vehicles in China IV emission regulations differ, the heavy-duty diesel vehicles in Beijing five emission standard provides for the first time limit values for emissions of particulate matter (PM), the standard to higher ahead of the forthcoming in the implementation of the five national emission standards.

On the technical route, Beijing five and the country five also exist differences.

Yu Wei Zhong said: "Beijing implementation of the heavy-duty diesel vehicles Beijing V emission standard and the five emission standards exist certain differences, Beijing five engine need to install DPF in the country five engine based on is diesel particulate trap is able to meet the emission requirements. Yuchai's five engine already in Beijing put into use, according to the Beijing V emission regulations, we have to secondary research and development on the country's existing five products, at present, related products have been sent to Beijing declared. "

It is understood, heavy-duty diesel engine's emission standards in five still uses SCR route, only on the basis of original National IV emission, adjust SCR calibration, five national emission can be realized, and the Beijing five engine must install DPF, in order to achieve the stringent emission requirements.

As the key of the five engine, DPF is composed of PM acquisition device, fuel injection device and control system.. When the DPF in the adsorbed particles reaches a certain limit, the ECU will open to DPF fuel injection of the fuel injection system, the DPF to capture particles full combustion complete regeneration, which can effectively purify the exhaust in 70% ~ 90% of the particles is one of the most effective and direct diesel engine particulate purifiers the method.

In an interview with Yu Wei Zhong said that after the introduction of the Beijing five regulations, enterprises and the Beijing environmental protection departments were full communication, in a clear understanding of the launch of demand and certification process eventually determine the technical route.

"In Beijing five engine in the process of research and development, the DPF calibration difficulty is very big to the. To this end, we invite relevant institutions to Germany and the United States joint research and development, now, to meet the Beijing V emission standards for products have been successfully developed, the relevant application materials have been sent to Beijing for approval, but completion of the examination and approval, production will not exist any problem." Zhong Yuwei said.

Yao Chunde also said that for heavy duty diesel engine production enterprises, Beijing five products R & D has a certain degree of difficulty, but the overall impact is not great, after all, Beijing heavy duty diesel machine market scale Co., and future nationwide in
