China unveils world's 1st diesel engine with 53.09% thermal efficiency
by Jijo Malayil
Since the invention of the diesel internal combustion engine 127 years ago, engineers and scientists have strived to improve its thermal efficiency.
In a markable advancement, the first diesel engine in history with an intrinsic thermal efficiency of 53.09 percent was unveiled by Chinese firm Weichai Power.
The firm showcased its new technology at the 2024 World Congress on Internal Combustion Engines, which commenced in Tianjin, China.
The accomplishment was recognized by TÜV SÜD, an internationally respected testing organization, and the China Automotive Technology & Research Center, a specialized testing entity for Chinese internal combustion engines.
Leading efficiency innovation
The percentage of diesel combustion energy transferred into useful engine output work without needing a waste heat recovery mechanism is known as the base engine's thermal efficiency. The engine's economy improves with the base engine's increased thermal efficiency.
