Some records are meant to be broken, but breaking them is not the only purpose. Just as Weichai Power continues to break the world record of engine thermal efficiency created by itself, what it pursues is not the record itself, but the value brought to the industry behind the record.
At the 2024 World Conference on Internal Combustion Engines, Weichai Power released the world's first diesel engine with a thermal efficiency of more than 53%. Two years ago, when Weichai launched a diesel engine with a thermal efficiency of 52.28%, the industry was shocked. In just over 500 days, Weichai Power has increased it to 53.09%, almost completing the impossible challenge, and it is no wonder that Wan Gang, chairman of the China Association for Science and Technology, said: "I am very happy to witness Weichai Power set a world record again!"
Obviously, this breakthrough of Weichai Power is of great significance to the current situation of the industry, first, the "double carbon" goal is getting closer and closer, and the low-carbon performance of traditional internal combustion engines is becoming more and more critical while developing new energy. Weichai Power's improvement in engine thermal efficiency is in line with the industry environment. Second, the fact that the environment of the truck industry has deteriorated makes it imperative to reduce costs and increase efficiency, and Weichai Power's high thermal efficiency engine corresponds to lower fuel consumption. Third, in the process of rapid development of mainland truck technology, it is natural that some technologies will achieve "overtaking" and become a leader in the development of the global industry. Looking at the parts enterprises in the domestic truck industry, there are not many such as Weichai Power that can achieve "world leadership" in technology, and Weichai Power has repeatedly led the world in thermal efficiency behind the signal of the rise of independent power brands.
In people's perception, the diesel engine, which has been around for 127 years, has been almost perfect in terms of products, and it is difficult to have much room for improvement. But Weichai Power doesn't think so, Tan Xuguang once said that diesel engines will always exist, of course, will always improve. It is precisely because of this belief that Weichai Power has made unremitting efforts to improve the performance of diesel engines, and its many breakthroughs in thermal efficiency are one of the important manifestations.
It is understood that the improvement of engine thermal efficiency is a very complex system engineering, which needs to be upgraded from the underlying architecture to the details and components to the core system. Weichai Power's thermal efficiency once again broke the world record, including the application of high-expansion combustion technology, high-efficiency fuel injection technology and other technologies, it is said that in the entire research and development process, there are 176 invention patents and 68 utility model patents. In the eyes of others, compared with 52.28% in November 2022, Weichai Power's 53.09% this time has only increased by 0.81%, but this 0.81% is composed of 0.01% one after another, it is a small breakthrough after a comprehensive achievement, and it is achieved by the process of failure and success again and again, in short, it is not easy!
In fact, it is no accident that Weichai Power has repeatedly broken world records, everyone in the industry knows that in the investment in scientific research, Weichai Power is one of the absolute best in the industry, as the so-called "one point of hard work and one point of harvest", it uses its efforts in daily life, and sets higher goals for itself.
Fate will never disappoint the people who have been working hard, Weichai Power's unremitting pursuit of engine technology, to Xiaoli, it is the necessary quality of Weichai Power to consolidate the king of technology, to Dali, it is the driving force for the continuous development of the industry. More critically, truck users need it, logistics fleets need it, truck companies need it, and China's diesel power needs it to the world.
Heroic Bravery:
Weichai Power's highlight moment at the 2024 World Internal Combustion Engine Conference will leave a strong mark in the history of global internal combustion engine development, which represents the enterprising spirit of human beings in the diligent pursuit of higher technology, the ingenuity of an enterprise to attack its main business without distraction in one field, and the ambition of China's commercial vehicle parts enterprises to lead the world with dreams. It is believed that 53.09% will soon become history, and one new data after another will be constantly refreshed, and in this process, Weichai Power will also become a famous engine brand at home and abroad!
