For over 100 years, Baudouin has designed and manufactured the highest quality diesel engines for marine and power generation applications globally
SDEC 25kW Diesel Engine
The Baudouin 4M06G25/5 highlights exceptional engineering balance, utilising a vertical inline four-cylinder layout with a 17.5:1 compression ratio optimised for highly efficient thermal profiles. The core engine architecture incorporates premium cylinder geometry alongside an 8-valve configuration to secure rapid volumetric air exchange. This robust cast-iron block features cross-flow cylinder head structures that isolate extreme structural loading points, effectively preventing head warping and maximising long-term field availability.
Industrial Power Architecture & Reliability
Designed with an integrated cylinder head and a high strength cast-iron block, the 4M06G25/5 utilises premier international component brands to ensure absolute mechanical integrity under rigorous load cycles. Its advanced layout guarantees optimal fuel atomisation and torque delivery, making it the preferred choice for local generator builders requiring reliable prime and standby power for commercial, agricultural, and residential infrastructure. With a simplified layout that drastically reduces part-count complexity, this engine lowers long-term operational overhead while maximising field uptime under demanding African environmental conditions.
Baudouin 25kWm Engine Technical Features
Marine-Grade Quality Infrastructure: Engineered backed by Baudouin's 100-year maritime heritage, ensuring extreme structural longevity, robust block thickness, and reliable continuous load-carrying capabilities.
Precise Governing Framework: Equipped with a highly sensitive electronic governor that complies with strict ISO 8528-5 Class G3 standards, providing an ultra-stable steady-state speed stability window of 0.5% or less.
Simplified Mechanical Framework: The structural blueprint relies on integrated components, reducing total part count compared to conventional diesel powertrains. This results in simplified field maintenance and lower spare parts overhead.
Strong Environmental Resilience: Engineered for instantaneous starting capability without an auxiliary device down to minus 5°C, and extending down to minus 15°C utilizing a water jacket heater for absolute grid-independence in cold regional climates.
Optimized Thermal Cooling Matrix: Features a mechanical radiator assembly with a belt-driven pusher fan designed for ambient operating temperatures up to 50°C, preventing thermal fatigue during intense high-load South African summer runs.
