With engines meeting National IV emissions standard
China Yuchai completes trial of natural gas buses and achieves climate requirements
80 buses manufactured by the Yutong Bus Group Co., Ltd. running on YC6G260N-40 engines have completed successfully their journey from Xining, Qinghai province, to the Tibetan Plateau, meeting the climate requirements for operating at high altitudes. Engines were supplied by Guangxi Yuchai Machinery (GYMCL), China Yuchai’s main subsidiary.
“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,” said Benny Goh, president of China Yuchai.
The YC6G260N-40 is a 6-cylinder engine with torque of 980 N.m at 1,400 rpm, which can use either CNG or LNG to power it. It features full-authority electronic controls with robust programming options and advanced diagnostics to optimize engine performance. Besides, it produces ultra-low noise and is compliant up to National 4 emissions standard.
GYMCL's engines have already been installed in the bus market in first-tier cities such as Shanghai and Beijing due to low emissions and high horse power. Last year, the company sold approximately 13,000 natural gas engines and expects to increase sales in 2012.
