China Tier 4 emissions regulation will come into force December 1, 2022 for industrial engines below 560 kW. 
Kohler engines meet the highest emission standards worldwide including China Tier 4. 

Kohler acknowledged the update by the Chinese authorities of the China NRMM Tier 4 emissions regulation, that will be implemented on December 1, 2022 for industrial engines with rated powers below 560 kW.

Kohler engines have been designed to meet the highest emission standards worldwide, and fully comply with China Tier 4. Kohler also offers support and expertise to OEMs to design 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” said 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.”

Important to note is also that the China Tier 4 emission standard has raised China Tier 5 standard prospectively, which reflects EU 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.
