Bukh DV10ME Marine Engine: Reliable Auxiliary Propulsion for Demanding Waters The Bukh A/S Bukh DV10ME is a robust, single-cylinder inboard diesel engine engineered for marine propulsion, delivering dependable 10 HP (7 kW) performance in safety-critical applications. As a 4-stroke cycle diesel, it excels in compact vessels where simplicity and endurance are paramount, powering everything from auxiliary drives to emergency systems with unwavering reliability. Key technical specifications underscore its marine-ready design: a 482 cm³ displacement (65 mm bore × 85 mm stroke) ensures efficient power from a lightweight 160 kg (352 lbs) frame, with dimensions of 693 mm L × 483 mm W × 672 mm for seamless integration into tight engine bays. It features seawater cooling for optimal heat dissipation in saltwater environments, an electric start system (12V, 1.3 kW) for effortless operation, and a 14V, 40A alternator to support onboard electrical needs like navigation and communication gear. The 2.5:1 gear reduction ratio optimizes torque delivery, while natural aspiration maintains consistent output without the vulnerabilities of forced induction in rough seas. Marine-specific benefits shine through its corrosion-resistant construction and robust sealing, which guard against saltwater ingress and ensure longevity in harsh conditions. The back-extract rating handles exhaust backpressure effectively, promoting stable performance amid variable loads and waves. Fuel-efficient diesel combustion minimizes consumption and extends service intervals, while the simple single-cylinder architecture reduces mechanical complexity, lowering maintenance demands and breakdown risks. Performance-wise, the DV10ME achieves rated power at 3,000 RPM, offering smooth operation for low-to-medium duty cycles, though its single-cylinder nature may introduce minor vibrations during extended runs. This trade-off is offset by exceptional reliability and integrated safety features, such as compatibility with lifebuoy systems for rescue scenarios. Ideal for small fishing boats, inflatable rescue crafts, and auxiliary power in yachts or workboats, the Bukh DV10ME prioritizes unyielding dependability over raw speed, making it a cornerstone for mariners who value precision engineering in life’s most critical voyages.
