The Chinese engine developer releases the world's first commercialized diesel engine with a brake thermal efficiency above 50 percent
Codeveloped with Robert Bosch GmbH. Chinese engine developer makes history in launching the world's first commercial diesel engine with a break thermal efficiency (BTE) of over 50%, thus setting a new benchmark. Currently, thermal efficiency of truck engines average around 46%.
Since the development of the first diesel engine in 1897, the engine's brake thermal efficiency of the diesel engine increased from 26 to 46 percent, where it remained until now. Although brake thermal efficiency evolved over the past 100-plus years, global development statistics and increasingly stringent emission regulations made improvement more difficult in recent years.
According to industry experts, increasing brake thermal efficiency from 46 to 50 percent reduces diesel consumption by 8 percent and carbon dioxide emissions by 8 percent. If all 7 million heavy-duty diesel engines now in use in China were replaced with diesel engines with 50 percent brake thermal efficiency, 33.32 million tons of fuel and reduce carbon dioxide emissions by 104.95 million tons can be saved annually - a significant contribution to solving energy shortages and global warming problems.
The launch of the engine solidifies China's position as a world leader in heavy-duty diesel engine technology. Weichai has received strong support from Bosch Group and other global suppliers and R&D consulting institutions in the development of this program. Weichai's future plans include partnering with more global companies to move toward a goal of 55 percent thermal efficiency, Chairman Tan Xuguang announced during the Sept. 16 ceremony.
