This is an important milestone in the history of global diesel engine development. On September 16, 2020, Jinan, China, Tan Xuguang, Chairman and CEO of Weichai Power, proudly announced to the world that the world’s first diesel engine product with a thermal efficiency exceeding 50% was launched in Weichai. born! Weichai, once again let the world admire! China's internal combustion engine industry, once again let the world peers look up!

Throughout the world, the history of diesel engine development is a history of continuous improvement in thermal efficiency. Since 1897, the world's first diesel engine was successfully launched. After a hundred years of transformation and upgrading and the application of new technologies, until today, the thermal efficiency of the diesel engine has increased from 26% to 46%. From the statistical data on the development of the thermal efficiency of diesel engines in the world, with the increasingly stringent emission regulations, the improvement of thermal efficiency has encountered a big bottleneck, and the difficulty of improving the thermal efficiency is becoming more and more difficult, and the progress is slow, which is a recognized technical problem in the world. Each 0.1% increase is a huge improvement in the development of diesel engines. Reaching 50% is like the first time in human history that 100 meters ran in 10 seconds.

Weichai people are not afraid of hardships and dare to challenge. With the courage of a technology strategist, Tan Xuguang regards technological innovation as the lifeblood of the company. The investment in R&D is not capped, and the global talents are recruited to establish a research team. Under his leadership, Weichai researchers bravely climbed the summit of science and technology, carried forward the spirit of "nail nails", sprinted towards the goal of 50% thermal efficiency all night long, and successively conquered five core technologies including diesel engine cooperative combustion technology, and solved efficient combustion. A series of international problems, such as diesel engine body thermal efficiency of more than 50%, meet the Euro VI (E) and China VI (B) emission standards, and the world's first mass production and commercialization conditions.

The China Automotive Technology and Research Center Co., Ltd., the most authoritative internal combustion engine testing and certification organization at home and abroad, and the German TÜV SÜD also issued a certificate with a thermal efficiency of 50.26% to Weichai. Dirk Hinzpeter, Director of Transportation Services Department of German TÜV Greater China, said that today we issued a test report with a thermal efficiency of over 50% to Weichai. This is the report we have issued with the highest thermal efficiency in the global internal combustion engine industry.

"Let the world peers look up to China's internal combustion engine industry", this is Weichai's original mission to revitalize China's equipment manufacturing industry. For 70 years, Weichai has been committed to the R&D and manufacturing of internal combustion engines. It has invested 30 billion yuan in R&D for 10 consecutive years. It has established the world’s only R&D and manufacturing base with an annual production and sales of one million engines in Weifang, achieving technological innovation in the global diesel engine industry. Leapfrogging development, and breakthroughs in commercial vehicle powertrain, CVT powertrain, hydraulic powertrain and other technologies, complemented China's core technical shortcomings in these three areas, and promoted China's diesel engine industry chain to continue to move towards high-end.

Core technology, the country's most important weapon. Today, Weichai’s breakthrough in the world premiere of 50% thermal efficiency diesel engine products has not only established Weichai’s leading position in the field of internal combustion engines in the world, but has also strengthened the backbone of Chinese equipment manufacturing. "Let the world's peers look up to China's internal combustion engine industry", Weichai has confidence, confidence and strength! Editor/He Yuting
