On November 20, 2022, WEICHAI released the world's first commercial diesel engine with bulk thermal efficiency of 52.28% and the world's first commercial natural gas engine with bulk thermal efficiency of 54.16%.

By setting two global records at a time, Mr WEICHAI is "off the charts". On the spot, Li Xiaohong, president of the Chinese Academy of Engineering, used "excitement" and "pride" to evaluate these two achievements.

German Bosch, International Federation of Automotive Engineers, Southwest Research Institute, AVL of Austria, Chinese Engine Engineers Association of North America, China Mechanical Engineering Society, China Internal Combustion Engine Society, China Internal Combustion Engine Industry Association and other domestic and overseas research institutes, industry institutions and strategic partners have also sent congratulatory letters and video.

What do these authorities at home and abroad say? What does WEICHAI look like to them? The author "steed up", dug out the core of WEICHAI adhere to science and technology self-reliance "four-wheel drive" -- self-driven, competitive drive, responsibility drive, open drive.

Self-drive: Become the global technology leader of internal combustion engine industry

In September 2020, WEICHAI released the world's first diesel engine with bulk thermal efficiency of 50.23%; In January 2022, WEICHAI increased the thermal efficiency of diesel engine body to 51.09%; After a gap of 10 months, WEICHAI once again introduced the world's highest bulk thermal efficiency diesel and natural gas engines.

Not complacent, dare to self-profile, so self-improvement. With three major breakthroughs in three years and a new global record set by himself, WEICHAI stands at the top of the global industry with his strength.

Stephen Hartong, CEO of Bosch Group, commented that WEICHAI's announcement of two major innovations represents a historic breakthrough in the history of the internal combustion engine and thus a new benchmark for global internal combustion engine efficiency. With these innovations, WEICHAI has become the world's leading manufacturer of diesel engines.

Helmut Liszt, CEO of AVL, said in a congratulatory letter: WEICHAI has made this progress in just three years. This new technology breakthrough has surprised the industry and demonstrated WEICHAI's strength in the core technology of internal combustion engine. It also proves that WEICHAI has become a global technology leader in the internal combustion engine industry.

Bosch Group is the world's largest automotive technology supplier, AVL is one of the world's three authoritative internal combustion engine research and development institutions. The two companies are gods to the global automotive and engine industry chain, and their judgment is authoritative.

It can be seen that WEICHAI released two global records in one day, which shocked the global industry and fully confirmed that WEICHAI has truly come to the center of the world stage!

Competitive drive: Surpass peers as "King of bulk thermal Efficiency"

Since the birth of diesel engine 125 years ago, the improvement of thermal efficiency has been the common pursuit of the global industry. WEICHAI set two world records, and one of the biggest things to watch was the bulk thermal efficiency.

What is bulk thermal efficiency? That is, the ratio of the energy from diesel combustion to the effective output of the engine without the use of waste heat recovery device.

It is understood that the 55% thermal efficiency diesel engine released by the Super Truck project in the United States relies on waste heat recovery to achieve, in the absence of waste heat recovery device, its thermal efficiency is 50.5%-51.5%. So far, the project is only in the laboratory stage, with no plans for commercial production.

WEICHAI's thermal efficiency is as high as 52.28%, and the three breakthroughs are all "bulk thermal efficiency", which can be commercialized. By contrast, WEICHAI is the king of the world.

Walter Downing, COO of the Southwest Research Institute, one of the "Big Four" global engine design consultants, said in a congratulatory letter that WEICHAI, the largest powertrain supplier in China, is committed to delivering higher powertrain efficiency. WEICHAI has launched a 13-litre diesel engine with a thermal efficiency of over 50%, and has been certified by TUV, the world's first official diesel engine that can achieve this great goal. WEICHAI's results were achieved without the use of complex and expensive waste heat recovery systems.

Chris Mason, CEO of the International Federation of Automotive Engineers, also praised WEICHAI for making significant progress in improving the thermal efficiency of the engine itself, which further highlights WEICHAI's strengths in key engine thermal efficiency improvement technologies.

Jing Wei, president of Chinese Engine Engineers Association of North America, also gave high praise to WEICHAI: WEICHAI has achieved a breakthrough in both diesel engine and natural gas engine thermal efficiency in less than one year, and has been certified by the authoritative testing agency, which has made important contributions to the development of internal combustion engine and national economic construction.

Responsibility driven: A "major power" to promote energy conservation and emission reduction

The field of transportation is an important battlefield to realize the "dual carbon" strategy, and the internal combustion engine plays an important role. The report of the Party's 20th National Congress proposed to "actively yet prudently promote peak carbon neutrality". As a leading company in China's internal combustion engine industry, WEICHAI has taken the initiative to play a leading role in all previous national emissions upgrades, from Country 1 to Country 6 and even Country 7 in the future.

It is estimated that a 52% thermal efficiency diesel engine can reduce CO2 emissions by 12%, and a 54% thermal efficiency natural gas engine can reduce CO2 emissions by 25%, compared with the industry average of 46% thermal efficiency diesel engine and 42% thermal efficiency natural gas engine. If all the commercial application, can reduce carbon emissions of nearly 100 million tons per year, to promote the traditional internal combustion engine industry energy conservation, emission reduction, green development of great strategic significance.

Chris Mason, CEO of the International Federation of Automotive Engineers, said in a congratulatory letter that the WEICHAI engine's endogenous thermal efficiency improvement will make a significant contribution to the sustainable development of the global industry, energy conservation and emission reduction.

The congratulatory letter from China Society of Internal Combustion Engine also gave high praise to the continuous breakthrough of WEICHAI engine thermal efficiency index, which makes a major contribution to China's energy saving and emission reduction work, and has important strategic significance to China's energy security.

Open driven: the integrator of global chain innovation

Only with openness and cooperation can the road become wider and wider. Tan summarized WEICHAI's innovative thinking as the "three Nos" principle -- no closing, no exclusion and no violation. To integrate the world's resources in an open manner; Link domestic and foreign advanced technology to develop self-owned brand construction; Abide by international laws on intellectual property protection.

Driven by such openness, cooperation and innovation, WEICHAI's "circle of friends" has covered the whole world, and both domestic and foreign industrial chains have been upgraded together. The two high thermal efficiency products released this time are the scientific and technological achievements made by WEICHAI and the whole industry chain.

Southwest Research Institute is excited about WEICHAI's upcoming products and hopes to continue working with WEICHAI for further technological advances.

WEICHAI and Weichai have learned a lot from each other over the years, says Stefan Pisinger, CEO of FEV Germany. FEV will do its best to support and participate in the development of WEICHAI and grow together with WEICHAI.

Tan Xuguang once said: "unchanged things have no vitality, the only constant in the development of enterprises is change." Although WEICHAI has held a number of "world's first" and "world's first", Weichai has always been "breaking the limit, climbing the peak" with powerful core "all-wheel-drive", and sprinting towards a higher goal.
