On January 8, 2022, Weichai Power released the world's first body thermal efficiency 51.09% diesel engine. Following the release of the world's first diesel engine with a thermal efficiency of more than 50.23% on September 16, 2020, Weichai issued another heavy news, which is another major revolution in the thermal efficiency of traditional power and also provides a strong technical preparation for the implementation of the "National VII" emission standard.
During the same period, Weichai concentrated on displaying the demonstration application results of multiple scenarios such as hydrogen energy parks, hydrogen energy ports, and hydrogen energy high-speed, and held the delivery ceremony of the first batch of hydrogen fuel heavy truck demonstration operations in Shandong Heavy Industry and Shandong Port. These are important phased achievements of Weichai's breakthrough in the key technologies of hydrogen energy and the realization of industrialization, and set up a model for the hydrogen energy industry.
Under the background of the "double carbon" strategy, the revolution of traditional power science and technology and the transformation of the new energy industry have pressed the acceleration button. At the beginning of 2022, Weichai has delivered major achievements in the fields of traditional power and new energy power, which has aroused widespread concern in the society, marking Weichai's successful opening up of a new path of diversified energy transformation, and fully demonstrating the strength and determination of Weichai's high-end power and new energy power to "walk in the forefront".
Driven by scientific and technological innovation
Lead the traditional power to the peak
Thermal efficiency improvement has been the common pursuit of the global industry since the birth of diesel engine 125 years ago, and it is also one of the important paths for Weichai to achieve transcendence in the transformation and upgrading of traditional internal combustion engines.
On September 16, 2020, Weichai released the world's first commercial diesel engine with a thermal efficiency of 50.23%, setting a new benchmark for the thermal efficiency of global diesel engines. In just over a year, Weichai once again set a new record, and the thermal efficiency of the diesel engine body reached 51.09% for the first time in the world, shocking the world.
From 50% to 51%, Weichai has entered no man's land in terms of thermal efficiency, there are no successful cases to learn from, and there are relatively few social resources to provide support. Tong Dehui, a scientist at Weichai and deputy general manager of Weichai Group, told reporters that Weichai's annual research and development expenses in the field of engines reach 5 billion yuan. Behind the large investment, Weichai sword refers to the peak of science and technology, and the scientific research team has overcome one international problem after another and achieved a number of original technological breakthroughs.
On the thermal efficiency track of the world's internal combustion engine, every 0.1 percentage point increase will greatly promote the revolution of traditional power technology. In the future, with the application of the technology of 51.09% thermal efficiency, Weichai's full range of diesel engines in all fields will be fully realized to lead the world, which is of great strategic significance for promoting energy conservation and emission reduction and green development of China's traditional internal combustion engine industry.
Demonstration first
Run out of the new energy power revolution "Weichai speed"
As the "double carbon" vision goal has gained more and more consensus in the world, hydrogen energy has become the future direction of energy transformation and development, and the research and development and industrialization of hydrogen energy technology have entered a accelerated stage.
Weichai, which adheres to the "two-legged" approach, has carried out an all-round strategic layout in the field of new energy. Backed by the National Fuel Cell Technology Innovation Center and the "Hydrogen into Ten Thousand Homes" science and technology demonstration project, Weichai's joint enterprises, universities and research institutes have formed a research and innovation synergy to accelerate the breakthrough of industrial chain technology bottlenecks and the landing of industrialization, successfully developed a 15-200kW series hydrogen fuel cell system, and built a 10,000-set fuel cell engine production base.
At the same time, multi-scenario demonstration applications were carried out in Shandong, creating the first in many industries, the first in China, and the first in China. Run out of the "Weichai speed" of the accelerated development of new energy power:
The first to carry out environmental adaptability tests of fuel cell fleets in extremely cold environments, and the first in the industry to achieve a product life of 30,000 hours;
The first high-power containerized hydrogen fuel cell combined heat and power system and the first 30kW solid-state oxide fuel cell combined heat and power supply system in China were put into operation in Weifang, pressing the acceleration button of hydrogen energy "flying" into ordinary people's homes;
Developed the first 3-ton hydrogen fuel cell forklift in China, created a zero-carbon logistics handling environment, and increased the size of the logistics industry;
The first 80-passenger hydrogen fuel cell passenger ship in China was successfully launched to achieve zero-carbon emission shipping;
Tractors equipped with Weichai's high-power fuel cell system were delivered to Shandong Port in batches, marking the successful launch of the country's first port hydrogen fuel cell heavy-duty truck demonstration operation project;
China National Heavy Duty Truck Yellow River Snow Wax Truck equipped with Weichai's 162kW hydrogen fuel cell system has achieved "China's first, world-leading and completely domestically produced";
Equipped with Weichai's full range of fuel cell vehicles, it successfully completed the intercity highway run, helping the country's first hydrogen energy high-speed heavy truck demonstration operation and construction......
These "firsts" are undoubtedly a good game of chess for the development of China's hydrogen energy industry to seize the global track.
Diversification is the direction of future energy development. In the scientific and technological revolution and industrial transformation of self-reliance, Weichai's traditional power and new energy power fly together, opening up a new path for the national "double carbon" strategy to diversify energy transformation.
