China Yuchai International Limited (China Yuchai) has completed a trial of natural gas engines operating at high altitude. Eighty buses, manufactured by the Yutong Bus Group Co., Ltd. and running on YC6G260N-40 natural gas engines supplied by Guangxi Yuchai Machinery Company Limited (GYMCL), the Company’s main operating subsidiary, journeyed from Xining, Qinghai province, to the Tibetan Plateau (the world’s highest plateau, average elevation exceeding 4,500 metres).

China Yuchai says the successful trial of the engine positions GYMCL as a key partner in the ongoing economic development of northwest China.

The YC6G260N-40 engine is a 6-cylinder engine with torque of 980 N.m at 1,400 rpm, which can use either compressed natural gas (CNG) or liquefied natural gas (LNG) to power it. The YC6G260N-40 low-noise engine is compliant up to National IV emissions standard.

Mr. Benny Goh, President of China Yuchai, commented, “As previously announced, GYMCL’s next focus will be on developing and producing a full portfolio of natural gas powered engines to complement its existing line-up of diesel engines. As a result of past initiatives, we are starting to launch a series of self-developed natural gas engines using our proprietary technologies and robust research and development program. Due to its low emissions and high horse power, many of our natural gas engines have been widely installed in the metro bus market in first-tier cities such as Shanghai and Beijing. Our YC6K natural gas engine which has been tailored specifically for the heavy-duty truck market, features 450-500 horsepower, which is the highest in its class in China.”

“In 2011, we sold approximately 13,000 natural gas engines and we look forward to increasing sales in 2012. The expanding use of our natural gas engines in China’s gas rich provinces supports the Chinese government’s initiatives to encourage energy conversation and emissions reduction,” Goh said.
