China Yuchai International's First 50 National V Compliant Diesel Engines Begin Commercial Operation

SINGAPORE, Nov. 19, 2010 /PRNewswire-Asia-FirstCall/ -- China Yuchai International Limited (NYSE: CYD) ("China Yuchai" or the "Company"), announced today that its first 50 diesel engines compliant with National V emissions certification are in commercial operations in buses operated by the Beijing Public Transportation Holdings, Ltd. These diesel engines are part of an order for 100 National V emissions certified diesel engines awarded to China Yuchai's main operating subsidiary, Guangxi Yuchai Machinery Company Limited ("GYMCL") by Beijing Public Transportation Holdings at the end of 2009.  

Since 2007, Beijing Public Transportation Holdings has purchased more than 3,000 buses containing National IV certified engines produced by GYMCL. The selection of GYMCL's diesel engines compliant with National V emissions standards demonstrates that GYMCL's green energy innovations are highly recognized thus reducing the technical gap between domestic and foreign produced diesel engines.  

The Beijing Public Transportation Holdings sets very high standards for vehicle emissions as part of their engine procurement efforts and has imported diesel engines meeting National II, III and IV emissions standards in the past due to the inability of domestically produced diesel engines to meet its stringent standards. However, GYMCL has worked closely with Beijing Public Transportation Holdings to ensure that its standards measure up to the latter's requirements resulting in GYMCL becoming the only domestic engine supplier to the Beijing Public Transportation Holdings.  

This development officially marks the commercial entrance of GYMCL's National V emissions compliant engines at a time when most diesel engine manufacturers are still introducing new engines to meet the lower National IV emissions standard. The National V diesel engine was independently designed and developed by GYMCL who has, since 2006 been driving the development of green energy diesel engine technology to reduce engine emissions and protect the environment.

Mr. Boo Guan Saw, President of China Yuchai, commented, "We are pleased to again be introducing new diesel technology into the marketplace. We are committed to being the technology leader in the quest for better fuel efficiency and low emissions diesel engines in China. With the most number of vehicles on the road among all of China's major municipalities and a commitment from the local governments to improve the environment, Beijing now has the highest emissions standards in China. The fact that we are the only domestic firm supplying diesel engines to Beijing Public Transportation Holdings is another strong endorsement of our research and development capabilities."
