December 2020， The Ministry of Ecology and Environment and the State Administration of Market Supervision and Administration jointly issued《Limits and measurement methods for exhaust pollutants from diesel engines of non-road mobile machinery（China is the third、Four stages）》（GB 20891-2014）Modification list，And issued its supporting technical specifications.《Technical requirements for pollutant emission control of non-road diesel mobile machinery》（HJ1014-2020）。

FromDecember 1, 2022Get up，All production、560% of imports and sales kWFollowing（Including 560 kW）Non-road mobile machinery and its diesel engine shall conform to“Guo Si”Emission standards。

“Guo Si”Switch，Sanyi Road Machine goes all out

Opening a New Era of the Fourth National Congress！

 

Power upgrade · Fourth National Emission

  

The picture shows the fourth year of Sanyidaoyizi.D09 Engine，Power：180kW

Three, one, fourCThe engines carried by 10 series of complete sets of road machinery and equipment comply with the fourth national emission standard.。

Sanyi Yizi Guo4 engine is adoptedDOC+DPF+SCR+ASCThe technical route of post-treatment，While meeting the Fourth National Emission Standard，It continues the strong power of the third national engine.、Advantages of energy saving and high efficiency。

National IV engine compared to national III engine，NOx emissions can be reduced by 13 percent%~45%，Particulate emissions can be reduced by 50 percent%~94%，More environmentally friendly。

Secondly，The SANY DEUTZ engine achieves automatic aftertreatment through special technical means.DPFRegeneration，Maximize machine attendance，Reduce customer maintenance costs，Add aftertreatment indicator to ensure efficient and safe operation of equipment。

The type spectrum is complete · Efficiency navigation

 

The fourth national paver released eight models in total.，From the compact and flexible 3-meter machine to the stable and efficient 13-meter machine，From“As thin as paper、Flat as a mirror”High-end thin layer asphalt paver to“One machine for multiple purposes、Smooth and efficient”Multifunctional paver，Everything you need。
