Weichai Power: launches the world’s first diesel engine with a basic thermal engine …
At 9:00 a.m. on January 8, 2022, Weichai Power launched the world’s first diesel engine with a base engine thermal efficiency of 51.09% and major achievements in hydrogen technology.
Tan Xuguang, CPC Secretary and Chairman of Shandong Heavy Industry Group, Chairman of Weichai Power and Director of Academic Committee of National Fuel Cell Technology Innovation Center, presented the research results of the world’s first diesel engine with thermal efficiency of 51.09% base engine developed by Weichai Power, the operation of the National Fuel Cell Technology Innovation Center and the “Hydrogen for Every Home” technology demonstration project. TüV SüD, a world-renowned testing authority, has issued a thermal efficiency certificate of 51.09% to Weichai Power. Then, the delivery ceremony of heavy hydrogen trucks for demonstration operation between Shandong Heavy Industry and Shandong Port took place.
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 expressed their congratulations for the diesel engine output by message or video link.
Evolve to new heights
Today, as green and low-carbon development has become a global consensus, China has set itself a strategic goal of achieving peak carbon by 2030 and carbon neutralization by 2060. The transportation is an important area for this purpose, and the internal combustion engine industry plays an important role. in this process.
Thermal efficiency is the measure of the energy efficiency of internal combustion engines: higher thermal efficiency means lower fuel consumption and better energy conservation and emission reduction effects. It is also a reflection of the technical power of a country in diesel engines. Improving thermal efficiency has been a common pursuit of the global diesel engine industry since the emergence of diesel engines 125 years ago. Weichai Power launched on September 16, 2020 in Jinan the world’s first commercial diesel engine with a core engine thermal efficiency of 50.23%, setting a new thermal efficiency benchmark for global diesel engines, just like the first time in the history of mankind 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 run was completed in 9 seconds, further reinforcing the importance of China in the global internal combustion engine industry.
The thermal efficiency of the base engine of 51.09% is another important revolution of the 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 to dominate the world in a full range of diesel engines, will be of great strategic importance in promoting the energy-efficient and environmentally friendly development of China’s traditional internal combustion engine industry, and will play a leading role in the global internal combustion engine industry.
It is estimated that compared to existing key products (diesel engines with 46% thermal efficiency) on the market, those with 51% thermal efficiency can lead to a 10% reduction in fuel consumption and emissions. carbon dioxide, thus saving fuel. consumption of 16 million tons and costs of about 140 billion yuan per year, and reduction of carbon dioxide emissions by 50 million tons per year. With the massive use of advanced technology in the industry, it will generate enormous economic and social benefits.
The hydrogen future
Shandong model for the 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 hydrogen heavy duty tractor units equipped 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 created at the initiative of Weichai Power. Meanwhile, the Ministry of Science and Technology (MOST) and Shandong have reached a framework agreement on the “Hydrogen for Every Home” technology demonstration project. Based on the center, the ministry 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, thus creating a duplicable Shandong sample for the hydrogen industry.
Since the launch of the “Hydrogen for Every Home” technology demonstration project, with strong support from MOST and Shandong, the National Hydrogen Cell Technology Innovation Center has set up an innovation consortium focused on Weichai Power and made up of ‘companies, universities and research institutes, to accelerate technical breakthroughs and industrialization, and successfully develop hydrogen fuel cell systems from 15 to 200 kW. The company’s 200 kW fuel cell systems were selected for the National Exhibition of Scientific Achievements during the “13th Five-Year Period” in October 2021. The company was the first to conduct a test of ‘Environmental adaptability of fuel cell vehicles in extreme cold, achieving successful one-time start at a temperature of 34 degrees Celsius below zero. The company was the first in the industry to produce products lasting 30,000 hours, pioneering the industrialization of Chinese fuel cells.
Based on its highly reliable fuel cell products, Weichai Power has made a multi-scenario demonstrative application. Regarding hydrogen powered fleets, the first high power container type hydrogen fuel cell heating and power generation system and the oxide fuel cell heating and power system solid 30 kW, both the first of their kind in China, were put into service in Weifang; The company developed China’s first 3-ton hydrogen fuel cell forklift truck, 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 with zero carbon emissions in Xueye Lake, Jinan; and the company launched China’s first heavy-duty hydrogen fuel cell truck demonstration project at Qingdao Port. In terms of hydrogen-powered highways, the company’s first Chinese highway hydrogen refueling station has entered service; A 49 t heavy fuel cell truck powered by Weichai traveled more than 5,000 kilometers between Taishan Steel, Jinan and the Dongjiakou area of Qingdao Port. On October 27, 2021, a fully homemade, world-leading, Chinese-made Sinotruk Huanghe ski waxing truck with a Weichai 162 kW hydrogen fuel cell system was delivered for use during the Olympic Games in Beijing winter 2022. On January 4, General Secretary Xi Jinping inspected the ski waxing truck. A series of results show that the “Hydrogen for Every Home” technology demonstration project is moving from model to reality.
Tan said that the core engine thermal efficiency of internal combustion engines of up to 51.09%, the massive application of new energies in products and the “double driving force” strategy have enabled Weichai Power to keep a step ahead in the development of traditional high-end engines and new energy engines, and has opened a new path of diversified energy transformation within the framework of the national strategy of peak carbon and carbon neutralization.
