Bukh DV24SME Marine Engine: Reliable Propulsion for Compact Vessels The Bukh DV24SME, engineered by Danish marine specialist Bukh A/S, is a robust inboard diesel engine tailored for marine propulsion in smaller vessels. This two-stroke, naturally aspirated powerplant delivers dependable performance through its twin-cylinder inline configuration, making it an ideal choice for auxiliary or primary drive systems in demanding saltwater environments. Key technical specifications underscore its engineering precision: a displacement of 964 cm³ (47.7 in³) with a square bore and stroke of 85 mm each, generating a rated output of 24.0 hp (DIN) at a minimum operating speed of 3,600 RPM. Weighing just 220 kg (485 lbs), it features compact dimensions—1,042 mm in length, 563 mm in width, and 737 mm in height—for seamless integration into tight engine compartments. The S-drev transmission, optimized for sail drive applications with hand-start capability, ensures efficient power transfer while minimizing gear losses and maintenance demands. In marine-specific applications, the DV24SME excels with its corrosion-resistant construction and low-speed torque characteristics, ideal for withstanding harsh conditions like prolonged exposure to saltwater and variable loads. Its diesel fuel efficiency, leveraging high energy density and thermodynamic advantages of the two-stroke cycle, extends operational range and reduces refueling costs. Reliability is paramount, thanks to a simplified design with fewer components—no turbocharger means lower failure points and enhanced uptime during remote voyages. Cost-effective maintenance further bolsters its appeal, with modular components that simplify repairs and minimize downtime. Performance-wise, the engine offers smooth, vibration-dampened operation at rated speeds, though its natural aspiration and higher RPM profile may produce noticeable acoustic output compared to four-stroke alternatives. While it lacks advanced emissions controls, potentially limiting compliance with stringent IMO regulations, this trade-off prioritizes rugged durability over complexity. Suited for small fishing boats, tenders, workboats, and yachts under 10 meters, the Bukh DV24SME provides versatile, space-optimized propulsion that embodies Scandinavian engineering: compact, resilient, and ready for the sea’s challenges.
