Ready for export. China Yuchai International has received On-Board Diagnostics emission certificates from the TÜV Rheinland Group for the marque's Euro III and Euro IV compliant diesel engines. Currently, Yuchai's lineup of engines includes six series 26 Euro III models as well as the newly-developed Euro IV series, named YC6J and YC6L.
This means that Yuchai's YC6J series engines (pictured) is now one of the five major Euro IV engine systems recognized by the European Union (EU). Yuchai is China's first heavy-duty diesel engine manufacturer to receive this certificate.

In China, OBD systems were adopted in all National III (a Euro III emission standard equivalent) compliant light-duty vehicles. After the roll-out of National IV standards, the city of Beijing is now requiring all new medium and heavy-duty vehicles to install this system, which issues a warning if a certain emission limit is exceeded through an on-board system monitoring of the automotive exhaust system.
