Comprehensive Product Portfolio

Weichai's generator set lineup encompasses an extraordinarily broad spectrum of power requirements, organised into distinct series that serve specific market segments. The WPG series represents the company's standardised generator set offerings, ranging from compact 125 kVA units to massive 2250 kVA installations . The WPG220F8 model, powered by the Baudouin 6M16G220/5 engine, delivers 220 kVA of standby power from its 9.7-litre, six-cylinder configuration, featuring electronic governing, closed-loop water cooling, and compliance with ISO 8528-5 Class G2 performance standards . Moving upward, the WPG550F8 utilises the Baudouin 6M21G550/5 engine to provide 550 kVA of standby power, with fuel consumption of just 109.5 litres per hour at prime power rating, demonstrating Weichai's commitment to operational efficiency.

For medium to large-scale installations, Weichai offers the M series engine platforms. The 6M31 land-based generator diesel engine delivers up to 880 kW of power in a compact, lightweight package, capable of achieving one-step loading to 50 percent with its Weichai self-developed ECU ensuring data security and reliable operation . The 12M55 platform, available in both diesel and gas configurations, powers generator sets up to 2,000 kW and has proven its mettle in demanding applications, including a 40 MW diesel power plant installation in Indonesia where twenty units operate continuously in high-temperature, high-humidity conditions.

At the pinnacle of Weichai's power range stands the revolutionary 20M61 diesel generator set, unveiled at the MEE2025 exhibition in Dubai. This "monster" of a generator represents the world's first high-speed diesel generator set to achieve 5 MW of power output, with an overhaul life of 15 years and exceptional reliability . It employs high-pressure common rail fuel injection technology, a high-efficiency high-pressure air intake system, and an optimised turbocharging design that ensures 0-100 percent loading without flame-out. The 20M61 meets United States EPA Tier 2 and China non-road Stage III emissions standards while delivering industry-leading transient response meeting G3 performance classifications.

Multi-Fuel Leadership

Weichai distinguishes itself through its comprehensive multi-fuel ecosystem, offering generator sets capable of operating on diesel, natural gas, methanol, and within hybrid configurations. The 12M55 land-based gas generator set features high-strength CGI cast iron construction for the engine block and cylinder heads, delivering exceptional durability and extended component lifespan . With automatic control systems, enhanced safety protection functions, and ultra-high automation enabling unattended operation, these gas generators provide intelligent, reliable power for applications seeking lower-emission alternatives to diesel.

The WP13 land-based methanol generator set represents Weichai's commitment to sustainable innovation. Utilising green and clean energy, this engine reduces pollutant emissions by 80 percent compared to conventional diesel engines while achieving 40 percent lower operating costs . Built on Weichai's high thermal efficiency platform, the WP13 maintains over 90 percent component commonality with diesel variants, ensuring serviceability and parts availability. With 500-hour oil change intervals and fully verified low-temperature starting performance, methanol generators offer an economically and environmentally attractive option for customers pursuing sustainability goals.

Baudouin Integration and Global Reach

Weichai's acquisition of the historic French engine manufacturer Baudouin has created a powerful synergy between Chinese manufacturing capability and European engineering heritage. Today, Weichai Baudouin products serve customers across Europe, the Middle East, Asia, and the Americas, with the combined brand firmly establishing "Made in China" as a mark of quality in global markets . Recent milestones include batch deliveries of 1 MW power generation products to European engineering rental projects, where Euro V-compliant engines featuring high-pressure common rail fuel systems and high-efficiency SCR aftertreatment deliver outstanding environmental performance alongside stable power output.

The Baudouin 6M16, 6M31, 12M33, 20M55, and 20M61 platforms now form an integrated product family spanning the complete power spectrum. The 20M55 gas generator set has become an industry benchmark for large-scale power applications, while the 20M61 diesel unit extends Weichai's leadership into the most demanding data centre and industrial applications.

Emergency and Critical Power Solutions

Weichai has developed an extensive range of emergency power products designed for rapid response and absolute reliability. The 16M55 land-based generator diesel engine starts within nine seconds and accepts load immediately, making it ideal for emergency power vehicles and critical infrastructure protection . With over 10,000 hours of reliability verification and a 32,000-hour overhaul period, this engine provides the dependability that mission-critical applications demand.

For mobile and temporary power requirements, the WP2.3 unattended enclosed generator set offers exceptional versatility. With a 1,000-hour maintenance cycle, adaptation to extreme environments including high temperature, high humidity and heat, salt spray, and dust, and intelligent control enabling ultra-long periods of unattended operation, these units serve emergency communication, disaster response, and remote facility applications. Outstanding NVH performance achieves minimum noise of just 55 decibels at seven metres, enabling quiet operation in urban environments.

Weichai's emergency generator sets covering 40-1,400 kW have obtained certifications from multiple classification societies including CCS, ABS, BV, and DNV, providing assurance of quality and reliability for marine and land-based critical applications alike.
