At 9 a.m. on January 8, Weichai Power Co.Ltd(000338) the launch of the world's first diesel engine with thermal efficiency of 51.09% and the Symposium on the operation of the national fuel cell technology innovation center and the "hydrogen into Wanjia" science and technology demonstration project were held in Jinan, Shandong Province.
At the meeting, Tan Xuguang, Secretary of the Party committee and chairman of Shandong heavy industry group, Weichai Power Co.Ltd(000338) chairman and director of the academic committee of the national fuel cell technology innovation center, reported on the scientific research achievements of the world's first diesel engine with thermal efficiency of 51.09%, the operation of the national fuel cell technology innovation center and the "hydrogen into thousands of homes" science and technology demonstration project. T ü v South Germany group, an international authoritative testing organization, issued the certification certificate with thermal efficiency of 51.09% to Weichai. Subsequently, the demonstration operation and delivery ceremony of the first batch of hydrogen fuel heavy trucks of Shandong heavy industry and Shandong Port was held.
climb the new peak of power
At present, green and low-carbon development has become a global consensus, especially in the field of transportation, which is an important battlefield to realize the "double carbon" strategy. In this process, the internal combustion engine industry plays an important role.
Thermal efficiency is the standard to measure the fuel utilization efficiency of internal combustion engine. The higher the thermal efficiency, the less fuel consumption, and the more significant the effect of energy conservation and emission reduction, which reflects the symbol of a country's comprehensive technical strength of diesel engine. The improvement of thermal efficiency is also the common pursuit of the global industry since the birth of diesel engine 125 years ago.
On September 16, 2020, Weichai Power Co.Ltd(000338) released the world's first commercial diesel engine with body thermal efficiency of 50.23% in Jinan, setting a new benchmark for global diesel engine thermal efficiency, just like the first 100 meters into 10 seconds in human history. After 480 days, Weichai Power Co.Ltd(000338) broke the record again. The thermal efficiency of diesel engine body reached 51.09% for the first time in the world, which is equivalent to running for 9 seconds on the 100m track, further improving China's voice in the global internal combustion engine industry.
Weichai Power Co.Ltd(000338) the thermal efficiency of diesel engine body has reached 51.09%, which is another major revolution in the thermal efficiency of traditional power. At the same time, it also provides technical preparation for the implementation of the "national seven" emission standard. The application of this technology will fully realize the Weichai Power Co.Ltd(000338) full range of diesel engines and lead the world in all fields; It is of great strategic significance to promote energy conservation, emission reduction and green development of China's traditional internal combustion engine industry; It plays an important technical leading role in the global internal combustion engine industry.
It is estimated that compared with the existing mainstream products in the market (average 46% thermal efficiency diesel engine), 51% thermal efficiency diesel engine can reduce fuel consumption and carbon dioxide emission by 10% respectively, save 16 million tons of fuel for China every year, and the economic benefit is about 140 billion yuan; Carbon dioxide emissions can be reduced by 50 million tons per year. In the future, with the large-scale application of this top technology in the industry, it will bring huge economic and social benefits.
build Qilu model of hydrogen energy industry
While promoting the breakthrough of traditional power technology and low-carbon upgrading, Weichai takes the development of new energy industry as one of the important strategic directions. This time, the first batch of Sinotruk Jinan Truck Co.Ltd(000951) hydrogen fuel heavy tractor delivered by Shandong heavy industry group to Shandong Port Group is equipped with Weichai high-power hydrogen fuel cell system, which has the characteristics of strong power, green environmental protection, safety, reliability, high efficiency and full attendance.
In 2021, Weichai Power Co.Ltd(000338) took the lead in building the only national fuel cell technology innovation center in China. At the same time, the Ministry of science and technology signed the framework agreement on the "hydrogen into thousands of homes" science and technology demonstration project with Shandong Province. Relying on the national fuel cell technology innovation center, it carried out multi scenario demonstration and application of hydrogen energy in Shandong, accelerated the breakthrough of key technologies and industrial development of hydrogen energy, and created a model Qilu of hydrogen energy industry that can be popularized and replicated.
Since the implementation of the "hydrogen into thousands of homes" science and technology demonstration project, with the strong support of the Ministry of science and technology and Shandong Province, the national fuel cell technology innovation center has established an innovation synergy with Weichai Power Co.Ltd(000338) as the core and joint research by enterprises, universities and scientific research institutes, accelerated the breakthrough of industrial chain technology bottle neck and industrialization, and successfully developed 15-200kw series hydrogen fuel cell system, Among them, 200kW fuel cell system participated in the national "13th five year plan" scientific and technological innovation achievement exhibition in October 2021; It was the first to carry out the environmental adaptability test of fuel cell fleet in extremely cold environment. It was successfully started at minus 34. It was the first in the industry to achieve a product life of 30000 hours, leading the process of fuel cell industrialization in China.
Based on highly reliable fuel cell products, multi scenario application demonstration was carried out. In terms of hydrogen energy park, China's first high-power container hydrogen fuel cell cogeneration system and the first 30kW solid oxide fuel cell cogeneration system have been put into operation in Weifang; The first 3-ton hydrogen fuel cell forklift in China has been developed to create a zero carbon emission logistics handling environment. In terms of hydrogen energy port, China's first 80 passenger hydrogen fuel cell passenger ship was successfully launched in Xueye lake, Jinan, realizing zero carbon emission shipping; The country's first port hydrogen fuel cell heavy truck demonstration operation project was launched in Qingdao Port International Co.Ltd(601298) . In terms of hydrogen energy high-speed, the first expressway hydrogenation station in China is put into operation in Zibo; The 49 ton fuel cell heavy truck with supporting Weichai Power Co.Ltd(000338) products runs for more than 5000 kilometers along the line from Jinan Taigang to Qingdao Dongjiakou port area. On October 27, 2021, Sinotruk Jinan Truck Co.Ltd(000951) Yellow River Snow wax vehicle equipped with Weichai 162kw hydrogen fuel cell system was delivered to the Winter Olympic Games, realizing "China's first, world leading and completely domestic". A series of achievements mark that "hydrogen into thousands of homes" is moving from blueprint to reality.
Tan Xuguang said that the thermal efficiency of the internal combustion engine body has reached 51.09%, new energy has been fully developed, large-scale demonstration and application, driven by Weichai's "double engine", and the traditional high-end power and new energy power are firmly at the forefront. In the scientific and technological revolution and industrial reform, it has opened up a new path of diversified energy transformation for the national "double carbon" strategy.
