China Yuchai Leads Natural Gas Bus Engine Market in Shaanxi Province

China Yuchai International Limited ("China Yuchai" or the "Company"), announced today that natural gas engines produced by the Company's main operating subsidiary, Guangxi Yuchai Machinery Company Limited ("GYMCL"), have been penetrating the key Shaanxi Province market in North-West Chinasince their introduction in early 2012. GYMCL's natural gas engines have enjoyed significant demand by municipal bus, tour coach and school bus operators in various Shaanximunicipalities including Yulin, Baoji, Yan'an, Tongchuan and Hanzhong.

After the delivery of the first batch of buses using GYMCL's natural gas engines to the Bus Industry (Xi'an) Co., Ltd. in Shaanxi Province in February 2012, a number of the province's passenger transport and bus companies started to purchase GYMCL's natural gas engines for the first time. GYMCL managed to break through in Shaanxi Province by employing an active marketing campaign to publicize the advantages of GYMCL's natural gas engines such as its superior economy and power, environmental benefits and low noise levels, engaging in frequent communications with the customers to understand their needs and offering an extensive after-sales service and parts network.

GYMCL has also captured a large share of China's overall natural gas engine market and its gas engine sales for 2012 is expected to increase to 20,000 units compared with the 13,000 units sold in 2011.

The Company's expanding natural gas engine portfolio now includes models such as the YC4D, YC6B, YC6J, YC6L and YC6M ranging from 140hp to 375hp, as well as the YC4G and YC6G models ranging from 180hp to 260hp. Additionally, Dongfeng trucks powered by YC6M and YC6MK natural gas engines have begun transporting coal from Yulin in the Yuyang District of Shaanxi Province to its capital, Xi'an. GYMCL's natural gas engines are highly adaptable to meet the needs of various customers.

Benny Goh, President of China Yuchai, commented, "With the new national energy development program emphasizing natural gas coupled with the increase in fuel prices, demand for our natural gas engines is rising. Shaanxi Province's central location strongly influences purchasing trends in neighboring vehicle markets, and our success there will help to promote our sales in surrounding regions. We look forward to increasing our production capacity to further extend our leadership from diesel engines into the natural gas engine market."
