From 1 December 2022，All production、560% of imports and sales kWFollowing（Including 560 kW）The fourth national standard will be fully implemented for non-road mobile machinery and its diesel engines.。This policy is bound to have a huge impact on the construction machinery industry.，And the one who guards us“Lucid waters and lush mountains”It is also the responsibility of every enterprise.。To this，We had an interview with Huang Cheng, director of the Institute of Atmospheric Research, Shanghai Academy of Environmental Sciences.，Let's talk“Guo Si”Those things~
Reporter：Briefly introduce the implementation of construction machinery industry“Guo Si”Background of emission standards、Purpose and significance。
Huang Suo：The full name of the fourth national emission standard is the fourth national emission standard for non-road mobile machinery.，It refers to all mechanical equipment using fuel engines applicable to the construction machinery industry.，Like an Excavator、Loader、Pile Driver、Bulldozer、Rollers, etc。Construction machinery belongs to a non-road mobile source.。In recent years，The state has carried out a lot of work in the management of atmospheric environment, focusing on industrial sources.，Remarkable results have been achieved.，However, the contribution of mobile sources is increasing with the increase of ownership.，There is an urgent need to strengthen emission control of mobile sources.。
Reporter：“Guo Si”What are the differences between the emission standards and the previous three national standards?？From Country One to Country Four，Which standards are becoming more and more stringent?？
Huang Suo：The fourth country is more environmentally friendly than the third.。First，The requirements of the Fourth National Congress have improved the quality of off-road mobile machinery emissions.，Several pollutant indicators have declined.。Second，The fourth country is more stringent in the management of the whole life cycle.；The fourth national standard should have the inspection of carbon substances.，After the carbon emission test, the engine should be tested on the construction road.，Higher requirements for the whole machine out of the warehouse。Other than that，Standard requirement 37kWThe engine carried by the fourth national construction machinery and equipment must have a terminal.，And that data transmission is carry out in the whole service life.，Environmental protection departments can track mechanical emissions for life.。
Reporter：At present, the construction machinery industry has mainly made targeted improvements to particulate matter and nitrogen oxides.。A few years ago.，The emission of motor Vehicle pollutants has implemented the sixth national standard.，What is the main difference between these two standards?？Will non-road mobile machinery regulations be aligned with motor Vehicle emission standards?？
Huang Suo：These two standards will certainly be aligned in the future.。We have done a lot of research in the process of raising the bid.，Also communicated with the majority of manufacturers.，Guarantee from the source，Improve the level of control，Ensure that the factory equipment meets the conditions。It has become a trend that the requirements of national standards are getting higher and higher.，In the future, the emission of construction machinery will gradually rise to the national five.、China VI Standard。
Reporter：What are the difficulties in the implementation of the Fourth National Standard?？
Huang Suo：The full implementation of the Fourth National Standard is a comprehensive test for the construction machinery industry.。First, enterprises need to accelerate technological upgrading.，Machinery manufacturing costs will also rise.，Therefore, I speculate that the industry price of the fourth national machinery will generally be higher than that of the third.。Second, we need enough testing institutions.，In order to detect the delivery and listing of the fourth national products.。Third, for imported machinery, we need to negotiate with foreign manufacturers.。
But in the grand scheme of things，There is no problem with the implementation of the Fourth National Standard.。Because after the standard is issued, it will be implemented.，Have a longer buffer period，At present, the market also has the ability to support the implementation of the Fourth National Standard.。Several leading enterprises in the domestic construction machinery industry，It has played an important supporting role in the upgrade of the fourth country.，For example, Sany, the leading enterprise of domestic construction machinery，It is ahead in the research and development of new products.，From product design、Emissions calibration、Machine commissioning and other dimensions lead the innovation and development of construction machinery.。
Reporter：After December 2022，The four national standards will be implemented throughout the country.，If the full switch，What changes will it bring to the environment?？
Huang Suo：Long-term consideration should be made to improve the atmosphere。Since the fourth national standard was put forward,，Some regions have responded positively to the policy.。The implementation of the Fourth National Standard，NOx to be cut by 13-45%，Particulate matter emissions can be reduced by 50 percent-94%。This will directly reduce the environmental pollution of construction machinery and equipment.，We are promoting air quality improvement.、While defending the green homeland，It will also promote the iteration of construction machinery products.。
Reporter：At present, the whole environment，Spurred on by the dual carbon target，What impact will it have on the construction machinery industry in the future?？Do you have any suggestions?？
Huang Suo：Under the increasingly escalating environmental protection situation，Energy structure will be further adjusted，Enterprises will strictly enforce the factory standards of equipment，Old construction machinery may face accelerated elimination，High-emission equipment will also be shuffled.，Speed up the renewal iteration of the construction machinery industry。It is an inevitable trend to upgrade the emission standards of construction machinery industry.，It is suggested that industry enterprises maintain product R & D capability and energy.，Relevant associations should also actively arrange for deployment.，Organize supporting work such as publicity and industry exchanges.，In order to meet the fourth national standard、And even the country five、Lay a solid foundation for the arrival of the era of six countries。
The matter of environmental protection，Merit in the present age and benefit in the future。“The fourth national standard”Implementation is imminent，How can the market fight this escalation war in a short time?，It is necessary for the factories, enterprises and users in the construction machinery industry to go hand in hand.、Deal with it together。
