We offer industry leading 24 month / 1,000 hour warranties on our engines and diesel generators.

The Baudouin 41kW Diesel Engine (4M06G44/5) is a liquid cooled four cylinder inline engine designed for commercial backup power and residential estate systems. This 2.3 litre turbo charged engine is designed for 40kVA prime to 44kVA standby generators.

  • Power Output: Supplies 41kW standby power at 1500 RPM (50Hz) and maintains operational stability during sudden load changes.
  • Turbo Charged Efficiency: Uses forced induction mechanics to increase power density while maintaining a compact physical footprint.
  • Local Suitability: Features a robust inline configuration and a 12V electrical starting system built to operate in high ambient temperatures and dusty environments.
  • Support & Delivery: Distributed by The Generator King with technical pairing assistance and direct access to genuine OEM parts.

We offer delivery across Sub-Saharan Africa at the best prices.

GENERAL SPECIFICATIONS

Baudouin 41kW Diesel Engine

Turbo Charged Performance

The 4M06G44/5 belongs to the Baudouin PowerKit series and utilises forced induction to deliver high power output from a low displacement engine block. This design provides efficient mechanical energy for light commercial facilities that require space saving setups capable of handling sudden block loads smoothly.

Liquid Cooling Architecture

An integrated liquid cooling system maintains stable internal operating temperatures during continuous runs. By circulating coolant evenly through the engine, it eliminates hot spots and reduces thermal stress on internal components operating in harsh regional climates.

Mechanical Strength and Regulation

Constructed with a heavy duty cast iron block, this 2.3 litre engine handles regular commercial load demands without strain. An advanced electronic governor monitors engine speed continuously to prevent frequency fluctuations. The simple mechanical layout simplifies routine maintenance and lowers long term operational overheads.

Key Technical Features
  • Durable Engineering: Uses heavy duty components to maximise engine service life and maintain fuel efficiency.
  • Manufacturing Standards: Produced under European quality control frameworks to guarantee uniform performance across all power installations.
  • Reliable Starting: The 12V single battery electrical system ensures prompt engine activation when utility grid power drops.
  • Efficient Combustion: Optimised fuel injection and turbo matching ensure clean combustion, lower emissions and predictable running costs.
