China Yuchai, through its main operating subsidiary Guangxi Yuchai Machinery Company Limited, has announced that its upgraded Yuchai S04220-61 series of engines are the first Chinese engines to be certified by the UN R49.07 Euro VI E stage emission standard. This certification also facilitates greater access for Yuchai to the European and American markets.

The certificate was awarded by TÜV Rheinland Greater China, an international independent third-party authority for testing, inspection and certification. The Euro VI standard is one of the world’s most stringent emission standards, with the UN R49.07 Euro VI E emission standards being the fifth and most strict stage to date with high technical requirements. Issued by the United Nations Economic Commission for Europe, it is applicable in more than 50 countries and regions including Europe, the Americas, Africa, Asia and Oceania, and with a wider scope of applications.

The upgrade S04 engine series is a medium-duty engine compliant with China’s National VI emission standards for use in light- to medium-duty buses and trucks. The upgrades include a larger displacement to 4.3 litres, increase in power to 220 horsepower, enhanced maximum torque by 18% and significant improvements to fuel efficiency.

China Yuchai President Mr Hoh Weng Ming said, “Attaining these advanced emission standards is part of our strategy to increase access to global markets.  Our engine exports have increased significantly in the first quarter of 2022 and we anticipate continued export growth as more potential customers become familiar with our Euro VI-compliant engines in these new markets.”
