The world's first ontology thermal efficiency 51.09% diesel engine developed by Weichai Group was released in Jinan today, which is the world's most thermally efficient diesel engine.
Today, the international authoritative testing organization T V SÜD issued a certification certificate of 51.09% thermal efficiency to Weichai. Xing Ruijiang, head of Shandong District of T V Nande Certification Testing (China) Co., Ltd., said, "This time Weichai Power's WP13H engine has undergone a rigorous testing process and proved that its highest effective thermal efficiency has reached 51.09%, which is at the most advanced level in the global engine industry. ”
Thermal efficiency is a measure of the fuel utilization efficiency of internal combustion engines, and the higher the thermal efficiency, the less fuel consumption. In 2020, the thermal efficiency of Weichai's commercial diesel engine body exceeded 50% in the world. Tong Dehui, deputy general manager of Weichai Group, said, "Breaking through 50%, which is equivalent to running 100 meters into 10 seconds, and now it has increased by 1%, which will become more and more difficult because it is gradually approaching the limit." This year we've added two new technologies. One is how our two-group spray technology can better convert burned heat into mechanical energy. Another one is low heat transfer. ”
According to estimates, compared with the average 46% thermal efficiency diesel engine of the existing mainstream products in the market, this diesel engine can save 16 million tons of fuel in China every year and reduce carbon dioxide emissions by 50 million tons. Walter Downing, COO of the Southwest Research Institute, said, "We look forward to the release of this product to further promote the advancement of science and technology." This achievement helps to reduce greenhouse gas emissions from diesel engines, thereby benefiting the global environment. ”
