MAN D2676 LE 424: Reliable Power for Marine Propulsion The MAN D2676 LE 424, engineered by MAN Truck & Bus AG, is a robust six-cylinder diesel engine tailored for marine propulsion systems. Designed to deliver dependable thrust in demanding maritime environments, it powers vessels with precision and endurance, ensuring seamless integration into auxiliary and main drive configurations. Key technical specifications underscore its engineering prowess: a crankshaft power output of 520 hp (382 kW) at a maximum operating speed of 1,800 RPM, with a displacement of 12.42 L (12,420 cm³). Fuelled by diesel and featuring liquid-cooled architecture, this inline-six configuration optimizes combustion efficiency while maintaining compact dimensions suitable for engine room constraints. Performance characteristics shine in marine applications, where the engine’s high torque delivery excels in propulsion demands, facilitating efficient towing, precise maneuvering, and sustained speeds under variable loads. Its thermal efficiency minimizes heat buildup during extended operations, while modular construction simplifies on-site maintenance, reducing downtime in remote offshore scenarios. Advanced emissions controls align with IMO Tier III and Phase III standards, curbing NOx and SOx outputs to meet stringent MARPOL regulations without compromising power density. For marine operators, the D2676 LE 424 offers distinct benefits, including a superior power-to-weight ratio for space-limited compartments, enhanced fuel economy during low-load cruising, and corrosion-resistant materials that withstand saltwater exposure and pressurized conditions. Engineered for 24/7 reliability with built-in redundancy, it ensures minimal interruptions on long voyages, while scalability allows customization for diverse hull designs. Ideal for tugboats, ferries, cargo ships, and workboats, this engine embodies MAN’s legacy of heavy-duty innovation. Backed by a global support network and certifications like SOLAS, the D2676 LE 424 combines resilience, efficiency, and environmental compliance—empowering modern maritime operations with unyielding performance.
