Sany Heavy Industry: The New Era of "China IV" Is About to Open, Are you ready?

Guo Si（CountryⅣ）Emission standard is the fourth stage of national non-road mobile machinery.Pollutant discharge standards，Engine emission pollutants mainly includeHC（Hydrocarbon）、NOx（Oxynitride）、CO（Carbon monoxide）、PM（Particles）Etc，Utilize external purification technology，By diesel particulate capture+Selective catalytic reduction or oxidation catalysis+Application of Waste Recycling Technology，Control and reduce the emission of pollutants to a standard below the specified value。

At present，The third phase of off-road mobile machinery has been implemented for nearly seven years.，Conditions are ripe for the implementation of the fourth phase of emission standards for non-road mobile machinery.。After December 1, 2022, the main engine factories and agents will not be allowed to sell the three new machines.，The fourth new machine of the country will step by step into the side of engineering robots.，It will appear on large and small construction sites one after another.。

Non-road country four（CountryⅣ）The implementation of emission landing is close at hand.，It means that construction machinery will be switched from the third country to the fourth country.，A new era is coming.。

·“Kunisan”And“Guo Si”The difference？

One is“Guo Si”Compared with emission standards “Kunisan” Emission standards are more environmentally friendly，NOx emissions are expected to be reduced by 13 percent%-45%Particulate emissions can be reduced by 50 percent%-94%；

The second is to clearly stipulate 37-560kWNon-road mobile machinery should be equipped with wall-flow particulate traps.(DPF)，Non-road mobile machinery with different power ranges adopt different emission control technologies(Such asDPF/DOC+DPF/DOC+DPF+SCR)，Increased costs also make a difference.。

·Why should it be implemented?“Guo Si”Emission standards？

“Win the battle of defending the blue sky”，Realization “Double Carbon”Aim

The implementation of the fourth national emission standard will improve the environmental pollution of construction machinery and equipment，Further strengthen the environmental protection management of old equipment，Speed up the renewal, iteration and innovation of construction machinery and equipment。

The fourth national upgrade iteration of Sany pile machine，It's not just about engine emissions.，It is also the birth of products of the times.，All-round upgrade of piling products，Stay tuned。The fourth national standard of Piling Machinery（CountryⅣ）Times，Are you ready?？
