The high-power high-end power generation engine Weichai Baudouin 20M55 is here!

On December 5th, at the Energy and Power Branch of Weichai's 2025 Global Partners Conference, Weichai Baudouin's 20M55 large-bore high-end power generation product made a stunning debut, attracting the attention of many attending guests. As the world's most powerful high-speed diesel engine, Weichai Baudouin 20M55 is mainly targeted at the power demands of data centers and can be said to be a breakthrough industry-leading product tailored for data centers.

Where is the breakthrough? Where does the leading position lie?

Its performance is powerful and far exceeds industry standards

It is reported that the maximum power of the generator set compatible with Weichai Baudouin 20M55 can reach 4,250kW, making it the most powerful model in Weichai Energy's power product series and also the world's largest power diesel generator set. In terms of power indicators, the single-unit power of the 20M55 diesel engine is 4,550 kW, the single-cylinder power is 227kW, and the specific power has reached an astonishing 41kW or more! Both the total power and the specific power have reached the global leading level, which can meet the strict requirements of data centers for backup power.

In the generator set industry, one of the most crucial indicators for evaluating product performance is the one-time loading performance. Whether it is total power or specific power, including its transient response index and one-time loading capability, it is globally leading. Zhang Yangyang, vice president of Weichai's Large Bore Engine Research Institute, told reporters. In addition, a very crucial requirement for the generator set in a data center is the reliability of start-up. It is necessary to ensure that the generator set can start up immediately in the event of a power outage to meet the power demand of the entire data center and thereby guarantee data security.

According to the relevant performance standards of the industry, a one-time loading of 50% load to reach G3 has already met the requirements of the vast majority of scenarios. The Weichai Baudouin 20M55 product not only meets the standards but also far exceeds the industry standards. Its one-time loading capacity can reach over 60%, achieving 100% no stalling during a single loading. This is precisely the best demonstration that Weichai Baudouin 20M55 possesses a very strong competitive edge.

Journalists have learned that Weichai possesses six core technologies to safeguard the security of big data, including self-starting response technology, control and starting redundancy technology, capacitive load carrying technology, independent ECU information security technology, 100% instant loading guarantee technology, and full life cycle intelligent alarm technology. These technologies have been further enhanced and strengthened on Weichai Baudouin 20M55, endowing it with features such as "high reliability, excellent economy, strong power performance, and high-end configuration", thereby meeting the ultra-high demands of big data centers for high reliability, intelligence, energy conservation and efficiency, and higher power density.

Customer satisfaction expands overseas markets

In the field of energy and power, Weichai has moved from the deep water zone to the uncharted territory. The Weichai Baudouin 20M55 is a typical representative. Whether in terms of product reliability or other performance indicators, it leads its peers.

Up to now, the performance of this product is leading worldwide. This year, the 20M55 underwent on-site tests by multiple overseas customers. The test results were highly satisfactory to the customers, including the transient response indicators and the reliability of the engine's continuous operation, etc. A cooperation intention has been reached. Zhang Yangyang disclosed.

This is because the 20M55 was designed with a high starting point and high requirements from the very beginning. As a product developed on a brand-new platform, its design and development concepts and indicators are globally leading, thus it has outstanding competitive advantages in terms of reliability, economy, adaptability, and modularization. In addition to meeting the basic requirements of data centers, the 20M55 can also achieve lower fuel consumption, less floor space, lower noise, etc., which can bring customers lower operating costs and higher availability rates. Zhang Yangyang said.

Since the beginning of this year, Weichai's generator sets have made significant progress in the field of data centers, becoming a strategic supplier for the three major communication operators, China Telecom, China Mobile and China Unicom, as well as a strategic partner of Internet data centers such as Baidu. In addition, Weichai has also achieved new breakthroughs in the data center markets of developed countries and regions such as Singapore and North America.

The rapid development of global artificial intelligence has driven an explosive growth in data computing power. The advent of the AI era has led to a sharp increase in the demand for backup power in data centers, presenting advanced products represented by 20M55 with a golden opportunity for development. Facing market opportunities, Weichai Energy Power has made full preparations in terms of products and production capacity to provide integrated power solutions for the construction of big data centers.
