Weichai claims latest diesel achieves over 50% brake thermal efficiency
By Jim Gibbins - 1st October 2020
China - Weichai Group of Jinan, Shandong province, a major producer of internal combustion engines has officially launched the first commercialised diesel engine in the world claimed to have a brake thermal efficiency above 50% (50.26%).
Brake thermal efficiency is a measure of fuel efficiency. Engines with higher brake thermal efficiency rates have lower fuel consumption, higher energy savings, and reduced emissions. Since the development of the first diesel engine in 1897, brake thermal efficiency increased gradually from 26% to 46%, 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 further improvement much more difficult in recent years.
