Representing the absolute pinnacle of high-output engineering within the 18.5L displacement bracket, the Baudouin 740kW Diesel Engine 6M31G825/5 is a highly responsive vertical inline 6-cylinder G-Drive plant. This massive model delivers enhanced torque density from its proven six-cylinder framework, acting as the ultimate mechanical core for heavy-duty 729kVA prime to 795kVA standby generating sets. Through a refined integration of high-pressure common rail injection and dual-stage aftercooling, the powertrain eliminates load-shedding frequency drop-off and secures instant electrical recovery during major block load steps.

Optimised to deliver continuous high-kilowatt output at 1500 RPM, this 18.5-litre workhorse features an advanced Engine Control Unit (ECU) for strict governing stability across volatile utility environments. The system incorporates a heavy-duty 24V twin-battery electrical starting grid driven by a 10 kW cranking motor to ensure instantaneous cold starts.

LiFeTIDE facilitates large-scale infrastructure deployment by pairing this premium French-engineered platform with deep technical alignment, substantial warehouse stock configurations, and efficient pan-African distribution.

GENERAL SPECIFICATIONS

Baudouin 740kW Diesel Engine

The Baudouin 6M31G825/5 showcases extreme mechanical refinement, sharing the same 18.5-litre displacement footprint and 149mm x 177mm bore and stroke profile as its series stablemate, but tuned for higher thermal output. The core engine architecture utilises a rigid cast-iron mono-block with an advanced 24-valve overhead cylinder head configuration to maximise volumetric air flow. Operating at an elevated 32 Bar BMEP (Brake Mean Effective Pressure) threshold under full standby loads, the structure is heavily reinforced with high-density main bearing webbing to isolate structural stress during sudden data centre or industrial plant connection sequences.

Industrial Power Architecture & Reliability

This heavy six-cylinder platform provides immense mechanical inertia to bridge severe inductive voltage variances caused by large mining equipment or commercial water treatment pumps. The integrated air-to-air aftercooling circuit drops incoming air temperatures significantly before combustion occurs, maintaining safe internal valve temperatures and completely eliminating the head-warping tendencies associated with smaller, over-boosted engine designs. This straightforward layout drastically reduces outer pipework complexity, giving local field technicians spacious access for routine servicing.

Baudouin 740kWm Engine Technical Features

  • Maximum 18.5L Power Density: Achieves an exceptional 740kWm standby output from an inline six platform, reducing the overall footprint inside heavy-duty soundproof canopies.

  • ECU Common Rail Technology: Leverages a modern electronic engine management framework to regulate high-pressure fuel delivery, resulting in pristine atomisation and minimal smoke output.

  • Expanded Oil Circulation: Features a high-capacity wet sump holding up to 60 Litres of oil, driving a 295 L/min internal lubrication loop to sweep away extreme frictional heat.

  • 10 kW Cranking Security: Outfitted with a premium 24Vdc starting network containing a 10 kW high-torque starter and an 80 Amp alternator for reliable black-start transfers.

  • Unassisted Cold Weather Firing: Engineered to secure immediate starting capability without pre-heaters down to minus 10°C, extending to minus 40°C using automated auxiliary cooling circuit heaters.
