WEICHAI Launched The World’s First Commercialized Diesel Engine With A Brake Thermal Efficiency Over 50%
Publication Date: 2020-09-20
On September 16, 2020, WEICHAI Group held a press conference in Jinan, Shandong, China, officially launching the world's first commercialized diesel engine with a brake thermal efficiency over 50%.

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% to 46%. From the statistics of the development of the brake thermal efficiency of diesel engines in the world, with the increasingly stringent emission regulations, the improvement of brake thermal efficiency has encountered a big bottleneck. 

WEICHAI has created five proprietary technologies: advanced fields synergy combustion technology, harmonius design technology, exhaust energy distribution technology, subzone lubrication technology and WISE control technology, which all help solve a series of world-class problems of high efficiency combustion, low heat transfer, high reliability, low friction loss, low emission pollutants and intelligent control, ensuring the brake thermal efficiency of the base diesel engine exceeds 50%.
