At present，Cummins Non-road National IV Intelligent Electronic Control Engine has been delivered in batches to the head enterprise of construction machinery main engine manufacturing.，Before the launch of a new product，After hundreds of thousands of hours of verification of various harsh working conditions.，Application range covers excavator、Loader、Rig、Bulldozer、Motor grader、Paver、Milling machine、Road Roller、Air compressor and many other categories，Excellent performance in all aspects。

CumminsPLUSSeries Tree National Four Power New Standard

At the time of the coming of the four laws and regulations of non-road countries，Cummins proposed“Reliable partner“、”Value Partners“、”Know the core partner“The new idea of the Fourth National Congress，And through full core optimization、Intelligent chain and professional customization of the fourth national high-end quality are interpreted.。

CumminsM15 PlusNew National IV Heavy-duty Engine，Mainly used in excavators、Rig、Milling machine、Air compressor and agricultural machinery，Power 420 to 503 kW，Maximum torque 3000 N∙Meters。M15 PlusIs a new member of the Cummins family.，Set new design、New materials、New technology in one，Advanced intelligent pilot system of Cummins，Achieve overall performance optimization，Mass production thermal efficiency up to 48%，And through innovative and customized design，Improve the self-protection ability of the engine，Dustproof、Heat insulation、Better performance such as wear resistance and noise reduction。M15 PlusHigh-efficiency turbocharging technology，New Turbine Flow Path Design and Optimized Blade Profile, Combined with optimized vortex tipDiffuserDesign, Ignificant improvement in supercharger efficiency, Faster engine transient response, Lower fuel consumption，Noise reduction is significant；SuperISOPodThermal insulation design, With a more environmentally friendly, high-temperature, lead-free bearing system, Improve the high temperature resistance of the rotor, Higher reliability。Adopt advancedNanoNet Modular nano fuel oil fine filter and engine oil filter，Special engine oil for the fourth national standard engine，Achieve ultra-long oil change cycle，While efficiently protecting the engine，Reduced maintenance and fuel costs。

CumminsL9 PlusNational Fourth Power，Mainly matched with excavator、Rotary excavator、Air compressor、Loaders and farm machinery，Power 219 to 294 kW，The maximum torque is increased by about 16% compared with the third stage%Up to 1800 cows·Meters。Through the innovation and iteration of the electronic control characteristics，Higher level of intelligence，Ability to sense load changes in advance，Adjust to the best working condition on demand。Close cooperation with the whole machine factory of engineering equipment，Proceed“Integration”Engineering Development and Lean Match，So that that engine is seamlessly Lin with the hydraulic system of the whole machine，Overall performance、Better key indicators such as energy efficiency。

Cummins 4-cylinderF4.5 PLUSNew China IV engine，Mainly used in 20-ton excavator，Power 129 kW，Unique two-stage supercharging technology。Relative to single-stage supercharging，Better low-speed transient responsiven，Higher intake efficiency，Greater power per liter，It can provide more power and torque under the same displacement。Due to the larger flow range of dual supercharging，The plateau power loss can be effectively reduced.，High altitude construction is more adaptable。

“Our off-road National IV power solution highlights Cummins' strategic new thinking on customized development for application environments.，Based on rich experience in global R & D and product application，Tailored for different markets in China，Instead of‘One size fits all‘。”Wang Kaijun pointed out，“Using Cummins in the United States EPA Tier 4、Europe Stage 5 and the technology and experience of the six aspects of China's automotive industry，And take advantage of Cummins' leading edge in China's automotive and off-road markets.，We can provide customized products that are more suitable for engineering equipment and its construction characteristics.，Meet the needs of the Chinese market and customers。“

However, the majority of users are concerned about the fourth national post-processing technology.，Cummins Emission Treatment Systems has over 20 years of experience in product development and application，SCR（Selective Catalytic Reducer）、DPF（Diesel particulate trap）And DOC（Diesel oxidation catalyst）More than one million units，Validated in the global market。According to the application characteristics of the fourth non-road country，Set up more sensors，The crystallization condition of the after-treatment system can be more accurately detected and self-adjusted，Helps reduce back pressure and engine fuel and urea consumption，Ensure the safety of reprocessing system，More stable and reliable performance。According to the characteristics of the engine platform,，Provide various import and export types and installation methods，Installation is more flexible，More space saving。

“Cummins as Power for Construction Machinery ‘Platoon leader’，Actively promote emission upgrading，Offer suggestions for the development of the industry，And continue to increase the intensity of localized research and development，Enhance production, manufacturing and service capabilities。“China Construction Machinery Industry Association President Su Zimeng said.。”Accelerated updates in the market、Under the influence of positive factors such as the implementation of environmental protection policies for air pollution prevention and control，China's construction machinery will be in reliability.、Durability，And greater breakthroughs in energy conservation and emission reduction.。As an enterprise rooted in China，It is hoped that Cummins will continue to develop diversified energy power.、Interconnection technology and other fields，Establish more and better cooperation with Chinese enterprises。”
