The picture shows the world's first diesel engine with a thermal efficiency exceeding 50%
Recently, China once again broke through the Western technology blockade, giving the West a heavy blow. According to domestic media reports, China recently exhibited the world’s first diesel engine with a thermal efficiency exceeding 50%. Compared with ordinary diesel engines, China’s new The developed diesel engine not only has high operating efficiency, but also has environmental protection features, which can greatly reduce carbon dioxide emissions. This is the first time that China has produced a world-class diesel engine. Previously, high-end diesel engines were monopolized by the West for a long time, and now China has broken through technology. After the blockade and the creation of a world-class diesel engine, the United States, Japan and Germany all vocally refused to accept it.

China’s ability to build the world’s first diesel engine with a thermal efficiency of over 50% is the result of increasing domestic demand for diesel engines with both high efficiency and environmental protection. Diesel engines are currently one of the most widely used power equipment, including automobiles and trains. Many vehicles including high-speed railways and national defense equipment need to use diesel engines. However, in the past ten years, high-end diesel engine technology has been monopolized by Western countries. China-made diesel engines are not only less efficient than Western countries’ diesel engines. At the same time, it will produce a lot of black smoke when in use, causing damage to the environment.
After 2007, China made major breakthroughs in diesel engine technology. Many high-power diesel engines were also born that year. A series of vehicles, including high-speed rail, used domestically-made high-power diesel engines at the time, although the performance was improved. , But the defect of large diesel engine pollution still exists. The main reason for the high pollution of diesel engine is that the diesel engine has low combustion efficiency. It will produce a large amount of carbon dioxide during operation and increase the amount of fuel used. In recent years, China The importance of environmental protection is gradually being emphasized. In the field of power generation, China has even begun to gradually abandon the hugely polluting coal power and vigorously develop clean energy such as photovoltaic power generation and hydropower generation.

In the case of environmental protection first, diesel engines naturally need to develop in the direction of environmental protection, and the breakthrough 50% thermal efficiency diesel engine developed by China this time is to significantly reduce carbon dioxide emissions without changing the operating efficiency. For traditional diesel engines, the diesel engines developed by China this time have a higher combustion efficiency, which is 30% as much as that of ordinary diesel engines. Due to the improved combustion efficiency, the carbon dioxide generated in the combustion chamber has been reduced by nearly half. There are currently about 7 million in the domestic market in China. If you replace all of these diesel engines with the newly developed diesel engines, China’s annual emissions reduction can reach 104.95 million tons.
The emergence of diesel engines that exceed 50% thermal efficiency has not only helped China solve the problem of excessive diesel engine pollution, but also made China lead the world in the field of diesel engine technology for the first time. For diesel engines with higher thermal efficiency, countries around the world have actually Research and development have already begun. International giants such as Daimler-Benz, Cummins, and Volvo have all launched research and development. However, these companies are still in a state of research, while China has already produced finished products. This also means that China is better than these international companies. The giants are even one step ahead of launching large-scale commercial applications.

In general, diesel engine is an important equipment in the industrial field. Although China has lagged behind the West in the past ten years, China has made achievements in the diesel engine field through continuous technological research and industrial layout over the years. The birth of the first diesel engine with a thermal efficiency of over 50% has enabled China to be in the forefront of the world. The development of China's diesel engine technology in the future will lead China's manufacturing to become world-class.
