Technological Revolution and Industrial Transformation, Weichai Power Launches the World’s First Diesel Engine with Core Engine Thermal Efficiency of 51.09%, Major Achievements in Hydrogen Power Technology

HONG KONG, January 13, 2022 – (ACN Newswire) – At 9:00 a.m. on January 8, 2022, Weichai Power (stock codes: 2338.HK; 000338.SZ) launched the world’s first diesel engine with a basic engine thermal efficiency of 51.09% and major achievements in hydrogen technology achievements.

Tan Xuguang, secretary of CPC and chairman of Shandong Heavy Industry Group, chairman of Weichai Power and director of the academic committee of National Fuel Cell Technology Innovation Center, presented the research results of the world’s first diesel engine with basic thermal efficiency. of 51.09% developed by Weichai Power, the operation of the National Fuel Cell Technology Innovation Center and the technology demonstration project “Hydrogen for Every Home”. TuV SuD, a world-renowned testing authority, issued a 51.09% thermal efficiency certificate to Weichai Power. Then, the hydrogen heavy truck delivery ceremony for demonstration operation between Shandong Heavy Industry and Shandong Port was held.

FISITA, MIT, AVL, FEV, SwRI, Bosch Group and Vitesco Technology, as well as China Mechanical Engineering Society, China Automotive Engineering Society, China Internal Combustion Engine Society and China Internal Combustion Engine Industry Associations extended their congratulations on the diesel engine output by message or video link.

Challenge limits, reach new heights

Now, as green and low-carbon development has become a global consensus, China has set itself the strategic goal of reaching carbon peak by 2030 and carbon neutralization by 2060. Transportation is an important area for this goal, and the internal combustion engine industry plays an important role. in this process.

Thermal efficiency is the measure of energy efficiency of internal combustion engines: higher thermal efficiency represents lower fuel consumption and better energy conservation and emission reduction effects. It is also a reflection of a country’s technical strength in diesel engines. Improving thermal efficiency has been the common goal of the global diesel engine industry since the advent of diesel engines 125 years ago. Weichai Power launched the world’s first commercial diesel engine with a base engine thermal efficiency of 50.23% in Jinan on September 16, 2020, setting a new thermal efficiency benchmark for global diesel engines, just like the first time in the history of mankind than a 100 meter sprint completed in 10 seconds. Just 480 days later, Weichai set a new world record by increasing baseline thermal efficiency to 51.09% as a 100-meter race was completed in 9 seconds, further cementing China’s importance in the global internal combustion engine industry.

The core engine thermal efficiency of 51.09% is another significant revolution of traditional engines, as well as technical preparation for the implementation of “China VII” emission standard. The application of this technology will help Weichai Power lead the world in a full range of diesel engines, will be of great strategic importance in promoting the energy-saving and environmentally friendly development of China’s traditional internal combustion engine industry, and will play a leader in the global internal combustion engine industry.

It is estimated that compared to existing leading products (46% thermal efficiency diesel engines) in the market, those with 51% thermal efficiency can result in 10% reduction in fuel consumption and carbon dioxide emissions. carbon, saving fuel consumption of 16 million tons and costs of about 140 billion yuan per year, and carbon dioxide emission reduction of 50 million tons per year. With the massive use of advanced technology in the industry, it will bring 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 made the new energy industry an important strategy. The first batch of Sinotruk’s heavy-duty hydrogen tractor trucks with Weichai’s high-power hydrogen fuel cell systems are powerful, environmentally friendly, safe, reliable and efficient for full-time use.

In 2021, the National Hydrogen Cell Technology Innovation Center, the only one of its kind in China, was established on the initiative of Weichai Power. Meanwhile, the Ministry of Science and Technology (MOST) and Shandong have entered into a framework agreement on the “Hydrogen for Every Home” technology demonstration project. Based on the center, the ministry has carried out a multi-scenario demonstrative application of hydrogen energy in Shandong and accelerated breakthroughs in key hydrogen technologies and the development of the hydrogen industry, thereby creating a Shandong duplicable sample for hydrogen industry.

Since the launch of the “Hydrogen for Every Home” technology demonstration project, with the strong support of MOST and Shandong, the National Hydrogen Cell Technology Innovation Center has established an innovation consortium centered on Weichai Power and consisting of companies, universities and research institutions, to accelerate technical breakthroughs and industrialization, and successfully develop 15-200 kW hydrogen fuel cell systems. The company’s 200 kW fuel cell systems were selected for the National Science and Technology Achievement Exhibition in the “13th Five-Year Period” in October 2021. The company was the first to perform a environmental adaptability test of fuel cell vehicles under extreme cold conditions, achieving unique successful start at 34 degrees Celsius below zero temperature. The company was the first in the industry to produce 30,000-hour life products, pioneering the industrialization of Chinese fuel cells.

Based on its highly reliable fuel cell products, Weichai Power has made a multi-scenario demonstration application. With respect to hydrogen-powered fleets, the company’s first high-power container-type hydrogen fuel cell heating and power system and the 30 kW solid oxide fuel, both the first of their kind in China, were put into operation in Weifang; the company has developed China’s first 3t hydrogen fuel cell forklift, creating a zero-carbon logistics handling environment. In terms of hydrogen-powered ports, China’s first 80-seat hydrogen fuel cell passenger ship developed by the company has been successfully tested without carbon emissions in Xueye Lake, Jinan; and the company launched China’s first hydrogen fuel cell truck demonstration project in Qingdao Port. As for hydrogen highways, the first highway hydrogen refueling station built by the company in China has been put into operation; 49t fuel cell heavy duty truck powered by Weichai has traveled more than 5,000 kilometers from Taishan Steel, Jinan to Dongjiakou area of ​​Qingdao port. On October 27, 2021, a Chinese-origin Sinotruk Huanghe ski waxing truck, world-leading and completely homemade, with a 162 kW Weichai hydrogen fuel cell system, was delivered for use during the Olympic Games in Tokyo. Beijing winter 2022. On January 4, General Secretary Xi Jinping inspected the ski waxing truck. A series of results marks the Hydrogen for Every Home Technology Demonstration Project moving from a project to reality.

Tan said that the core engine thermal efficiency of internal combustion engines of up to 51.09%, the massive application of new energy in products, and the “dual driving force” strategy, have enabled Weichai Power to advance in the development of high-end traditional engines and new energy engines, and opened a new path of diversified energy transformation under the national carbon peak and carbon neutralization strategy.
