Recently, there is only one big male protagonist in the internal combustion engine circle.
He Nobe, Vice President of TÜV SÜD North Asia, presented Weichai Power with the world's first product test report with a thermal efficiency of more than 53%.
At the 2024 World Conference on Internal Combustion Engines, Tan Xuguang, who is accustomed to receiving awards, skillfully received the world's first product test report with a thermal efficiency of more than 53% from He Nobel, vice president of TÜV SÜD North Asia, an international authoritative testing organization. He didn't even say a word, but he was the most shining actor at the opening ceremony.
Back on April 1, 2022, at the 2021 annual results conference, Tan Xuguang, known as "Tan Daring", said amazingly when new energy was "rising": "New energy vehicles, especially passenger cars, will have a catastrophic overcapacity. ”
Tan Xuguang interprets Weichai Power's 2023 financial report
After two years, on the occasion of the 20th anniversary of Weichai Power's listing, at the 2023 annual results conference, Tan Xuguang faced an aggressive question from investors - what do you think of your previous remarks about new energy overcapacity, he responded: "I still adhere to the point of view of a few years ago, and I also want to warn our friends in the industry, calm down the brain, don't have a fever, I think new energy is more important, research how to reach 1000 kilometers, how to make the whole scene can be used, this is very important." ”
Not only that, Tan Xuguang also publicly stated that he was recently studying a topic "New energy cannot replace diesel engines", and firmly believed that "the future must be a multi-energy strategy, and diesel engines will never disappear".
53.09% thermal efficiency diesel engine
On April 20, 2024, the release of the world's first diesel engine with a thermal efficiency of more than 53% perfectly responded to all his previous remarks about "new energy and internal combustion engines".
When it comes to Tan Xuguang, the industry has always had such a perception - there is nothing he dare not say. The only contrast is that "Tan Daring" is a down-to-earth helmsman, realizing his "let go of the cannon" and "bragged bull" one by one.
"One day is used for two and a half days", "not fighting for the first place is in the mix", "the leader of the enterprise must understand the product"...... Tan Xuguang has the physical strength and fighting spirit of young people, flying everywhere around the world, managing hundreds of companies at home and abroad. When answering investors' questions in "Lao Tan Lounge", Tan Xuguang treasured the products and data of many listed companies, and analyzed the general trend of industry development. The author and institutional investors issued a unanimous exclamation - the male protagonist of the really cool drama and the domineering president are also.
This "domineering president" has repeatedly used data to speak in the main business of diesel engines.
The technical investment behind the improvement of the thermal efficiency of the body
Over the past ten years, Tan Xuguang has led Weichai engineers to go through 4,000 days and nights of collective wisdom research, open cooperation with the world's top universities and research institutes, collaborative innovation with the global industrial chain and supply chain, and constantly break through themselves in the thermal efficiency of the diesel engine body. Since 2020, Weichai Power has successively released the world's first thermal efficiency of 50.23%, 51.09%, 52.28% and 53.09%, achieving four major leaps in diesel engine thermal efficiency in four years and setting a new benchmark for global diesel engine thermal efficiency.
In short, the thermal efficiency of the body is to develop four key core technologies around the four major systems of combustion, air, fuel and friction - high expansion combustion technology, mixed-flow supercharging technology, high-efficiency fuel injection technology, and low-resistance friction reduction technology, so as to continuously improve the thermal efficiency of the diesel engine body without any waste heat recovery device.
Wan Gang, Chairman of the China Association for Science and Technology, highly affirmed Weichai Power's achievements at the 2024 World Conference on Internal Combustion Engines
The world exceeded the 53% mark for the first time, which is of far-reaching significance for the internal combustion engine industry. At the opening ceremony of the 2024 Global Conference on Internal Combustion Engines, Wan Gang, Chairman of the China Association for Science and Technology, highly affirmed Weichai Power's research and development achievements in the thermal efficiency of diesel engine bodies, and witnessed the birth of another new world record at the scene.
For the end user, it's a real savings. 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 is increased by about 14%, which can save about 31 million tons of fuel and reduce carbon emissions by about 97 million tons per year. According to the calculation that the heavy-duty tractor runs 250,000 kilometers a year, it can save about 12,000 liters of diesel every year, and the current diesel market price is 7.8 yuan per liter, which can save about 98,000 yuan for the owner a year. In addition to the field of transportation, this technological achievement will also be applied to construction machinery, agricultural equipment, ships, power generation equipment and other fields in the future, making new contributions to China's economic and social development.
Lei Jun responded to "Shuangwen's first male lead" and said: "I think that success in life depends on dreams, struggle, and opportunities in this era to ......", similar scripts, Tan Xuguang's answer is to "make a good product for a lifetime" without distractions, leading Weichai to make the engine the first in the world.
"53.09%" is just a stepping stone, the starting point for Weichai Power to move towards another peak. From the peak to the peak, from the limit to the limit, Weichai Power's "peak moment" is not only at this time, but also in the future.
