Kohler welcome the new China Tier 4 regulation

The new standard will come into force in 2022


From 17-19 March 2021, CCMA (China Construction Machinery Association) has hosted the “Non-road Mobile Machinery Tier 4 Emission Standards Exchange Seminar” in Wuxi, Jiangsu Province (China).

The summit covered many topics, such as the national environmental protection laws and regulations policy interpretation, the industry situation analysis and the introduction to environmental emissions compliance responsibilities of machinery manufacturers. All major stakeholders of the sector were present, from the relevant government representatives to association leaders, from industry experts to main manufacturers.

Kohler could not miss this event of critical importance, especially because environmental protection has always been a major concern for the company and was honored to be invited to present its strategy for the near future. 

On the path towards worldwide harmonization of emissions legislation, radical changes in engine and drivetrain technology have been driven by the new worldwide standards over the last few years.

The Chinese authorities issued an important update of the so called “Limits and Measurement Methods for Exhaust Pollutants of Diesel Engines of Non-Road Mobile Machinery”, also known as “China NRMM Tier 4”.

The regulation will be implemented on December 1, 2022 for industrial engines with rated powers of <560 kW. 

Kohler engines have been designed to meet the highest emission standards worldwide, and fully comply with China Tier 4. Kohler also offer support and expertise to OEMs in efficiently and inexpensively designing a China 4 compliant product line.

“The new China Tier 4 emission standard for non-road mobile machinery sets highly demanding requirements on particulate matter emission. Kohler has already upgraded the traditional engine fuel system, intake and exhaust systems and control system, to provide OEMs with fully compliant engines” declared Li Shaoqi, Director of Commerce, Kohler Engines Asia Pacific. “The upgrade from China 3 to China 4 is much more challenging if compared to the previous from China 2 to China 3, but Kohler, leveraging the experience gained in highly regulated markets, is able to offer enhanced performance, a smart exhaust after-treatment strategy, heavy duty design, as well as guarantee low cost of ownership” said Li.

Noteworthily, the China Tier 4 emission standard has raised China Tier 5 standard prospectively, which reflects the Euro Stage 5. Therefore, as Chinese users opt for Kohler engines to upgrade to China Tier 4, they would save the laborious development when China Tier 5 will come into force over the next few years.
