SINGAPORE, Sept. 5, 2013/PRNewswire/ -- China Yuchai International Limited (NYSE: CYD) ("China Yuchai" or the "Company") announced today that the YC6K 6 cylinder 12L series of engines developed by Y & C Engine Co., Ltd. ("Y&C"), a joint venture of the Company's principal operating subsidiary, Guangxi Yuchai Machinery Company Limited ("GYMCL"), have been awarded the European Union's ("EU") E-mark certification.

In order to enter the EU market, automotive systems, electronic products and a variety of related components must be certified to meet the basic requirements of traffic safety, noise levels and environmental protection. The E-mark is a compulsory safety certification mark which the European Commission requires member states to display on motor vehicles, parts and systems.

The tests were conducted on Y & C's test stands which are certified to Euro IV and Euro V emission standards as well as on-board diagnostic certification for heavy-duty engines, and all tests were successfully completed.

Mr. Weng Ming Hoh, President of China Yuchai, commented, "By achieving the stringent E-mark certification, we have demonstrated that our advanced engines meet global technology and performance standards. Our YC6K diesel engines can now access countries that adopt EU regulations, which significantly broaden our export opportunities for these engines."
