National standard IV for off-road mobile machinery
Implementation from now on
CCTV's In-depth Visit to Xugong
Focus on construction machinery in the face of the four new national standards
New changes、New products、New initiatives
According to the requirements of the Ministry of Ecology and Environment，From December 1，560 that do not meet the requirements of the Fourth National StandardkWFollowing（Including 560kW）Non-road diesel mobile machinery and diesel engines，Production will be banned、Import and sales。
1The fourth national standard pays more attention to the limit requirements of the number of new particulate matter particles emitted by the whole machine.
XCMG's products related to the Fourth National Standard include Excavators.、Loader，Tractors、Harvester、Rotary Drilling Rig、Rollers, etcMore than 30 categories，Operation scenario covers agriculture、Port、Mine、Basics、Road construction and other fields。Among，Excavator is the largest category in the single market.。
Deputy General Manager of XCMG Excavation Machinery Division Geng Jiawen said in an interview with CCTV.：
Compare“Kunisan”Standard，“Guo Si”Exhaust emission of the standard to the product，They all have higher requirements.。On the emission limit，Guo Si（Approval）Ratio of nitrogen oxides to the third country（Standard）It's down 50%，AtPMOn the concentration limit，Down 90%，One tenth of the original，A new limit for particulate matter emissions per kilowatt-hour has been added.。In the past, the main body of emission responsibility was the engine manufacturer.，Now it has become a main engine factory。
In order to meet the latest emission standards，Improved engine is the key，XCMG Excavator Customized Engine Aftertreatment Device，Used to reduce the initial particulate matter and nitrogen oxides in the exhaust，And in the Vehicle、Platform and other levels.，Carry out standardization of communication data，Ensure the interconnection between Vehicle data and monitoring platform，The real-time monitoring of emission data is realized.。
02Strong performance, more comfortable, after switching to the fourth country, product stability is enhanced
In addition to meeting the requirements of the Fourth National Standard，Xugong has comprehensively upgraded the performance and operation experience of the new products.。
Take the main equipment loader for earthwork construction in engineering construction as an example.，XugongXC9 series loaders apply XCMG's exclusive large displacement、High Torque、High Power National IV Engine，Match different working modes for different working conditions，Power comprehensive performance improvement 11%，Fuel consumption is reduced by 5%Above，Both the combined working capacity and the boom breakout force are increased by 12%，Shoveling is easier。Large hinge、Long wheelbase、All-condition design with large steering angle，Matched with mature boxes that have been tested by the market for a long time、Bridge、Hydraulic components，Provide strong guarantee for product reliability。
New International Cab Offers Wider Vision，Larger operating space，More portable operation feeling，More comfortable multi-directional adjustable shock absorption seat，Let the operator work for a long time without fatigue。
Basic construction machinery covers a wide range of categories.，The upgrade of the fourth national new standard，Products such as Rotary Drilling Rigs have also been optimized in key technologies.。Application of engine match hydraulic system under different work condition，Reduce fuel consumption while further improving work efficiency。Optimize engine noise design，Average reductionThe external radiation noise of the whole machine is about 3dB(A)。Other than that，Engine filter、Diesel filter, etc. shall be moved to the engine room door.，Convenient maintenance，The maintenance cycle is extended to 500 hours.，The cost performance has been greatly improved。
For Xugong Agricultural Machinery，At present, high-powered Tractors and crawler Harvesters in Xugong have realized the fourth national switch.。Through the analysis of field test data，Compared with the third national emission，After the fourth national engine is configured，Overall Heat Dissipation Performance Improvement，And that operation stability is enhance，It solves the problem that has been plaguing agricultural machinery.。
At the same time，Xugong Agricultural Machinery Passes Series Optimization，Scientific optimization of tail gas treatment system of the whole machine，Cleaner exhaust emission，Bring the operator a clean and comfortable working environment。
03Performance advantages are outstanding and downstream enterprises are optimistic.“Guo Si”New product
Products relative to the third national standard，“Guo Si”The new product realizes the upgrade iteration of performance and experience.，It is favored by buyers.。
XCMG Excavation Machinery Purchaser——Fu Qiang, chairman of Jiangsu Xuzhou Hualei Blasting Engineering Co., Ltd., said.：
The structural parts of the fourth national product have been enhanced.，The reliability is obviously improved；Overall power of the equipment、The hydraulic system and control system have been completely upgraded.，The configuration is in the lead，Fuel consumption and unit consumption are lower.，Reduced usage and maintenance costs for our users。
As a purchaser of XCMG Port Machinery，Liu Changsheng, general manager of Fangxing Handling Service Co., Ltd., Xuzhou City, Jiangsu Province, said.：
Through the investigation of technical personnel in the early stage，We feel that the application of XCMG's fourth technology is relatively mature at present.，Many enterprises in the industry have purchased the equipment of the fourth national port machinery of XCMG.。
Compared with the third country，XCMG Four Frontal Crane Still Maintains Strong Power，At the same time for fuel efficiency、Man-machine comfort and so on.，It has also made a great technological upgrade.，The response of the device is also very fast.，The new post-processing system is also very worry-free.。
The fourth country's strong attack，XCMG took the initiative to recognize the change、Seek change、Strain，Stick to the main business of construction machinery，Unswervingly abide by“High-end、Intelligent、Greening、Service-oriented、Internationalization”Direction of development，Build with high quality development performance“A century-old shop”，Speed up the construction of world-class modern enterprises，Climbing the Global High-end Equipment Manufacturing Industry Everest！
