Improving the thermal efficiency of internal combustion engines is not only related to fuel saving, but also closely related to carbon reduction. This has become the main technical direction of the global internal combustion engine industry.
On April 20, on the occasion of the 2024 World Internal Combustion Engine Conference, the internal combustion engine industry ushered in another historic breakthrough. Weichai released the world's first diesel engine with a thermal efficiency of 53.09%, once again setting a world record in the field of this technology.
Overcome a number of key technologies and make new breakthroughs in thermal efficiency
As a basic manufacturing industry, the internal combustion engine is facing unprecedented challenges under the global low-carbon transition trend, but it is also ushering in unprecedented development opportunities. In recent years, in the process of exploring the path of "carbon neutrality", the internal combustion engine has become the product with the most potential to promote energy conservation and emission reduction. Improving thermal efficiency is one of the most direct and effective ways to reduce the carbon emissions of internal combustion engines.
As a leader in the internal combustion engine industry, Weichai has set four new world diesel engine thermal efficiency records. In September 2020, Weichai released the world's first diesel engine with a body thermal efficiency of 50.23%, in January 2022, Weichai increased the diesel engine body thermal efficiency to 51.09%, and in November of the same year, this data reached 52.28%.
At the event, Van Waald, CEO of TÜV SÜD North Asia, an international testing organization, sent a congratulatory video. He said that the thermal efficiency of the diesel engine body exceeded 53%, reflecting Weichai's strong scientific research and technical strength, and he hoped that this achievement could increase China's "dual carbon" goal and green development, and contribute to the sustainable development of the global industry.
This once again confirms that on the road to the peak of thermal efficiency of internal combustion engines, Weichai has made great efforts to engrave the mark of China by virtue of its leading innovation achievements, and has added glory to Made in China while enhancing the mainland's voice in the global internal combustion engine industry.
The more efficient and fuel-efficient, the more economical it is, to achieve the unity of economic and social benefits
Thermal efficiency is the standard for measuring the fuel utilization efficiency of internal combustion engines, the higher the thermal efficiency, the lower the fuel consumption, and the better the product economic performance.
In recent years, under the superposition of factors such as low freight rates and high oil prices, the freight market has been difficult, and the living space of cardholders has been further squeezed. In such an environment, the product economy is good, and it has stronger practical significance for the majority of cardholders.
According to the data, according to the current calculation of China's diesel engine ownership, compared with the 45% ~ 46% thermal efficiency level, the economy of 53% thermal efficiency diesel engine has increased by about 14%, and the annual driving of 250,000 kilometers can save users about 98,000 yuan in fuel costs.
It can be said that the advent of Weichai's high-thermal efficiency diesel engine will not only help achieve the goal of energy conservation and emission reduction and "double carbon", but also create greater value and higher benefits for cardholders, and the unity of social and economic benefits will also provide a feasible reference for the internal combustion engine industry to break the situation and achieve high-quality development.
Brief summary:
The release of Weichai's world's first 53.09% thermal efficiency diesel engine not only established Weichai's leading position in the field of internal combustion engines in the world, but also the crystallization of its years of deep cultivation in the internal combustion engine industry and focus on world-class core technical difficulties.
More importantly, Weichai has shown with practical actions that the internal combustion engine still has strong vitality as the dominant power of commercial vehicles. In the future, with the large-scale application of high-thermal efficiency diesel engines, Weichai is bound to leave a strong mark in the development of the national carbon reduction industry, so that the traditional internal combustion engine industry will continue to glow with vitality.
