China Yuchai International says its main operating subsidiary, Guangxi Yuchai Machinery Company (GYMCL), has introduced 12 new engines to be launched in 2013.

Seven of the models are National V-compliant natural gas engines and the other five are National IV-compliant diesel powerplants.

The engines are GYMCL’s new products for 2013 as China is expected to implement the National IV emission standards nationwide and introduce the National V gas engine emission regulations this year.

The new natural gas engines, which cover the 120-440 horsepower range, are: YC4DN-50; YC4GN-50; YC6JN-50; YC6GN-50; YC6LN-50; YC6MKN- 50 and YC6KN-50.

All the gas models are compliant with China’s National V emission standards and use technologies such as lean combustion and electronic closed-loop control systems.

The 5 new models of National IV-compliant diesel engines include the model YC4S as a new platform and the YC4EG and YC6A-45 models, which have been upgraded from their original platform, as well as truck specific models such as the YC6J-46 and YC6A-46.

“We have been increasing our research and development efforts these past several years to develop our own independent technology to ensure our engines remain industry leaders and retain core competitiveness,” said China Yuchai president, Benny Goh.

“These new engine models combine high performance with improved energy savings and lower engine emissions to provide the solutions required by our customers in a rapidly changing environment as well as meet increasing stringent national regulations on energy conservation and emissions reduction.”
