"The heart of the engine, the belly of the diesel engine!"
Do you know what kind of industry secrets are behind this sentence?
When Western countries blocked our diesel generator technology for decades, it was broken through by China's Weichai in one fell swoop.
And in 2020, Weichai successfully developed the world's first diesel generator with a thermal efficiency of more than 50%.
A new era begins.
This diesel generator is one of the Weichai diesel engine series.
However, at the meeting, experts from Germany's authoritative testing agency, holding the test report, announced the data of this diesel generator, which is enough to support a new era.
In the end, what kind of ability does this diesel generator have to break the technological blockade of the West and surpass the birthplace by itself?
In terms of thermal efficiency, this diesel engine can be as high as 54.7%!
In the case of 90% efficiency of the generator set, this means that the thermal efficiency of the Weichai diesel unit has reached 50%!
Neither the engine birthplace of the West nor Germany, which has always been the leader in the field of diesel engines, has not broken this record.
And now, a Chinese Weichai Group suddenly appeared in front of them, and then was told by China's Weichai Group: "Your master has been surpassed by a super excellent apprentice."
Immediately, this diesel generator was labeled "Made in China".
A new era began.
The diesel engine industry is divided into three phases: the first stage is from 1890 to 1915, the second stage is 1950, also known as the engine stage, and the third stage is 1990.
Among them, the diesel engine in the 90s has begun to gradually switch with the electric generator, and the generator has begun to occupy the main market for diesel engines in the early 90s.
In the new century, the diesel generator industry has entered the generator stage.
Earlier, we talked about Weichai's diesel generator, what is the meaning behind it.
We can look at two aspects of diesel engine: the first point is the thermal efficiency of the generator set, and the second point is the environmental performance.
Thermal efficiency of diesel generators.
A few years ago, the mainland had made a detailed standard for diesel engines: "Diesel Engine Exhaust Pollutant Emission Standards".
At the same time, in this standard, the country has implemented the "national three" and "national four" successively.
In order to further reduce emissions, the mainland has begun to implement new emission standards, and the environmental protection requirements are more stringent.
In order to encourage domestic enterprises to develop a new generation of high-efficiency, low-pollution, low-emission diesel engines.
It is precisely because of these national standard requirements that diesel engine companies are forced to continue to break through technical bottlenecks.
So as to improve the technical threshold of diesel engines, but also for the production and technical use of diesel engines, to provide a unified standard.
Weichai's high-efficiency diesel engine also meets and meets the national standard requirements.
It is of great significance to the thermal efficiency of diesel generators.
Only when the thermal efficiency of the diesel engine passes the national standard, it can not only ensure the stability of the industry, but also help to enhance the market competitiveness of the diesel engine.
Achieve breakthroughs in core technologies.
With the continuous development of the mainland's economy, the market demand is increasing.
For this reason, the global diesel engine companies are becoming more and more competitive in this market.
After the introduction of technological transformation and upgrading in the fifties and sixties of the 20th century, the diesel engine industry in mainland China has been continuously carrying out technological innovation.
At the same time, many diesel engine enterprises such as Weifang Diesel Engine Factory have also entered the market competition.
After several years of hard work, Continental's diesel engine has made significant progress in many performance and parameters.
So far, the diesel engines made in mainland China have been able to meet international standards in terms of performance, so as to have international competitiveness.
During this period, the mainland's Weichai Group began to innovate in technology.
At the same time, research and development has gradually entered the right track.
Weichai has made a major breakthrough in the research and development of diesel engines through technology introduction and independent innovation.
A strong R&D team and technical system have been established, and independent technology and core competitiveness have been formed.
In the process, Weichai has made unremitting efforts to meet or exceed international standards, thus establishing a good reputation and brand image in the market.
Weichai's sales of light-powered diesel engines increased by 174% year-on-year, with a market share of 19%.
Weichai's success is mainly due to its adherence to the concept of independent innovation and its focus on R&D and technological progress.
Weichai is also attracting outstanding talents from all over the world, and has strengthened cooperation with universities and scientific research institutions.
On this basis, Weichai has also carried out a series of mergers and acquisitions and integrations to seek further technological improvements.
Weichai's technical strength has gradually increased and it has become a leader in the industry.
At the same time, Weichai is also constantly exploring and innovating in diesel engine environmental protection technology.
Through scientific and technological innovation, Weichai has reduced the emission of pollutants from diesel engines by 80% and minimized the noise of diesel engines.
This indicates that Weichai has been at the forefront of the industry in terms of environmental protection.
In the diesel engine manufacturing process, Weichai is also constantly innovating, and using advanced technologies such as nanotechnology, so that the performance and reliability of the diesel engine have been greatly improved.
At the same time, Weichai is also exploring new diesel engine energy sources, such as biodiesel, aiming to further reduce the emission pollutants of diesel engines.
Environmental implications.
The environmental performance of diesel engines is mainly reflected in the "National VI" standard implemented on August 1, 2017.
Before the implementation of the "China VI" standard, the mainland set different limits for the pollutant emissions of diesel engines.
This limit mechanism is mainly reflected in the concentration and quality of emissions-related substances of diesel engines.
At that time, the "China III" standard set the limit of "carbon monoxide" emission concentration at 0.7g/kWh, while the "China IV" standard raised this limit to 0.5g/kWh.
Until today's "China VI" standard, this limit has been further raised to 0.3g/kWh.
It can be seen that the update and revision of the diesel engine standard in the mainland not only reflects the gradual reduction of pollutants emitted by the oil generator in the mainland, but also reflects the continuous progress in the technology of the diesel engine, and also reflects the efforts made by the mainland in environmental protection.
Weichai's diesel generator has far exceeded the national standard for pollutant emissions.
And in the first two years of the implementation of the national standard, Weichai has reduced the pollutant emissions of diesel engines to 60% of the national standard.
The emissions of this diesel generator are only 40% of the original emissions.
It is equivalent to reducing emissions by 50% on the basis of the new "China VI" emission standard implemented next year.
epilogue
Weichai's success is not only a victory for the diesel engine industry in China, but also a major breakthrough in China's high-end machinery manufacturing field.
Today, Weichai is not only constantly innovating and striving for breakthroughs in the field of diesel engines, but also has achieved great success in hydrogen fuel cell technology.
In 2021, Weifang officially established the Hydrogen Energy Research Institute and put a lot of effort into the hydrogen energy power system.
The successful development of hydrogen fuel cell technology will play an important role in the development of diesel engines in the future.
It is precisely because of the success of Weichai that the entire Chinese diesel engine industry can continue to move towards high-end and high efficiency.
The world's first diesel generator with a thermal efficiency of more than 50% has not only gained more attention and recognition in the market by virtue of this technological breakthrough, but also marks China's continuous innovation and progress in the field of machinery manufacturing. This historic breakthrough will surely affect the direction of diesel engine development in the future.
Weichai will also continue to explore and innovate in diesel engines, and make greater contributions to promoting the efficient and environmentally friendly development of diesel engines. It is hoped that the diesel generators of the future will be more efficient and environmentally friendly, and make greater contributions to sustainable development.
Weichai's technological innovation in the field of diesel engines can provide reference and inspiration for the transformation and upgrading of China's manufacturing industry. SOEs should actively explore new business models and technology paths to cope with an increasingly competitive market environment.
Weichai's technological innovation in various fields also demonstrates China's potential and innovation ability in the high-tech field, and is expected to occupy a larger share of the global market.
At the same time, under the current situation of increasing uncertainty in the international trade environment, Weichai's breakthrough in technological innovation will help reduce its dependence on external technologies, improve its independent innovation capabilities, and enhance its market response capabilities.
China should increase investment and support for high-tech enterprises, promote technological innovation and industrial upgrading, and promote high-quality economic development.
In the future, with the increasingly stringent environmental protection regulations, the technological innovation of diesel engines will be the key to promote the sustainable development of the traditional power industry.
As a leading enterprise, Weichai should continue to maintain the advantages of technological innovation and lead the development trend of diesel engines in the market.
