LEADING GENERATOR MANUFACTURER
For over 100 years, Baudouin has designed and manufactured the highest quality diesel engines for marine and power generation applications globally
GENERAL SPECIFICATIONS
Baudouin 640kW Diesel Engine
The Baudouin 6M31G725/5 is characterised by massive structural engineering margins, introducing a giant 18.5-litre displacement configuration with a large-scale 149mm x 177mm bore and stroke profile. Operating on a 14:1 compression ratio optimised for high-density electronic common rail thermal loads, the robust cast-iron mono-block utilises a 24-valve overhead configuration (4 valves per cylinder) to facilitate lightning-fast volumetric air changes. This rigid block architecture isolates extreme cylinder pressures reaching an intense 27.7 Bar BMEP (Brake Mean Effective Pressure) under full emergency load, ensuring long-term structural integrity.
Industrial Power Architecture & Reliability
This multi-cylinder platform introduces unparalleled mechanical torque stability to absorb massive inductive load steps from heavy machinery, automated data centres, and industrial processing plants. Incorporating an air-to-air charge air cooling matrix, the intake charge temperature is dropped significantly before combustion, which preserves internal valve seating and prevents the cylinder head warping associated with inferior, over-stressed engine blocks. The streamlined external design minimises loose plumbing links, vastly lowering field upkeep demands for site engineers.
Baudouin 640kWm Engine Technical Features
ECU Common Rail Efficiency: Utilises an electronic engine management system alongside high-pressure common rail injection to achieve flawless throttle adaptation and minimal fuel mist waste.
Massive Industrial Oil Sump: Features an expansive lubrication network holding up to 60 Litres of engine oil, supporting an exceptional oil flow rate of 295 L/min to keep internal journals protected.
High-Volume Radiator Array: The fully integrated mechanical cooling package holds 60 Litres of coolant, backed by a 17 kW belt-driven pusher fan designed to combat severe 50°C summer ambient heat waves.
10 kW Cranking Performance: Employs a heavy-duty 24Vdc negative-to-ground electrical starter framework with a 10 kW motor and an 80 Amp charging alternator for bulletproof automated grid coupling.
Extreme Weather Tolerance: Natively refined to ensure unassisted mechanical firing down to minus 10°C, extending down to a freezing minus 40°C utilising specialised auxiliary starting devices.
