Weichai Group, a leader in China's internal combustion engine industry, has officially launched the world's first commercial diesel engine with a brake thermal efficiency over 50 per cent.

At the ceremony held on September 16, 2020 in Jinan, Shandong, world renowned testing organisation TÜV SÜD and China Automotive Technology and Research Center, China’s national internal combustion engine testing organization, both awarded Weichai certificates for brake thermal efficiency of 50.26 per cent. Ling Wen, vice governor of Shandong Province and faculty member of the Chinese Academy of Engineering, and Tan Xuguang, chairman of Shandong Heavy Industry Group and Weichai Group, jointly unveiled the world's first commercial diesel engine with a brake thermal efficiency over 50 per cent.

Brake thermal efficiency is a measure of the fuel efficiency of internal combustion engines. The higher the brake thermal efficiency is, the less the fuel consumption will be and the better the energy saving and emission reduction performance will be. Since the world's first diesel engine was successfully developed in 1897, after a hundred years of transformation and upgrading and new technology application, the brake thermal efficiency of the diesel engine increased from 26 per cent to 46 per cent until now.
