Weichai Power Releases Diesel Engine with a Base Engine Thermal Efficiency
HONG KONG, Jan 13, 2022 – (ACN Newswire) – At 9:00 am on January 8, 2022, Weichai Power (Stock codes: 2338.HK; 000338.SZ) released the world’s first diesel engine with a base engine thermal efficiency of 51.09% and major achievements in hydrogen technology achievements.
Tan Xuguang, CPC Secretary and Chairman of Shandong Heavy Industry Group, Chairman of Weichai Power and Director of the Academic Committee of the National Fuel Cell Technology Innovation Center, reported the research findings of the world’s first diesel engine with a base engine thermal efficiency of 51.09% developed by Weichai Power, the operation of the National Fuel Cell Technology Innovation Center and the “Hydrogen for Every Home” technology demonstration project. TuV SuD, an world-renowned test authority, issued a certificate of thermal efficiency of 51.09% to Weichai Power. Then the delivery ceremony of hydrogen-powered heavy-duty truck delivery for demonstrative operation between Shandong Heavy Industry and Shandong Port was held.
FISITA, MIT, AVL, FEV, SwRI, Bosch Group and Vitesco Technology, as well as the China Mechanical Engineering Society, the China Automotive Engineering Society, the China Internal Combustion Engine Society and the China Internal Combustion Engine Industry Associations extended congratulations on the release of the diesel engine by message or video link.
Challenging Limits, Scaling New Heights
Today when green and low carbon development has become a global consensus, China has set the strategic goal of achieving carbon peak by 2030
Transportation is an important field for this target, and the internal combustion engine industry plays an important role in this process.
Thermal efficiency is the yardstick for the fuel efficiency of internal combustion engines: higher thermal efficiency represents lower fuel consumption and better effects of energy conservation and emission reduction. It is also a reflection of a country’s technical strength in diesel engines. Improving thermal efficiency has been the common pursuit of the global diesel engine industry since diesel engines emerged 125 years ago. Weichai Power released the world’s first commercial diesel engine with a base engine thermal efficiency of 50.23% in Jinan on September 16, 2020, establishing a new thermal efficiency benchmark for global diesel engines, just like the first time in human history that a 100-meter sprint was completed in 10 seconds. Just 480 days later,
Weichai set a new world record by increasing the base thermal efficiency to 51.09% just as a 100-meter race was completed in 9 seconds, further enhancing China’s significance in the global internal combustion engine industry.
The base engine thermal efficiency of 51.09% is another significant revolution of traditional engines, as well as a technical preparation for the implementation of the “China VII” emission standard. The application of this technology will help Weichai Power lead the world in a full spectrum of diesel engines, be of great strategic significance to promoting the energy-efficient and green development of China’s traditional internal combustion engine industry, and play a significant leading role in the global internal combustion engine industry.
According to estimation, compared with existing key products (diesel engines with thermal efficiency of 46%) on the market, those with a thermal efficiency of 51% can lead to a reduction of 10% in fuel consumption and carbon dioxide emissions alike, saving fuel consumption by 16 million tons and costs by approximately 140 billion yuan annually, and reducing carbon dioxide emissions by 50 million tons annually. With the massive use of the top technology in the industry, it will generate huge economic and social benefits.
Hydrogen-powered Future, Shandong Model for Hydrogen Industry
While promoting the innovative and low-carbon development of traditional engines, Weichai Power has taken the new energy industry as an important strategy. The first batch of Sinotruk hydrogen-powered heavy-duty tractor trucks with Weichai’s high-power hydrogen fuel cell systems are powerful, eco-friendly, safe, reliable and efficient for full-time use.
