The Weichai 12WH17 Series Marine Diesel Engine delivers exceptional durability, fuel efficiency, and high-performance output suitable for large commercial vessels, fishing boats, offshore fleets, and marine industrial applications across the UAE.
Built with a high-strength engine block, crankshaft, connecting rod, and a large-flow lubrication system with pre-cooling filtration, this engine is designed to achieve an overhaul interval of 20,000+ hours ensuring long-term reliability in harsh marine environments.
The electronically controlled high-pressure common rail system, turbocharger, and optimized combustion chamber work together to achieve strong power, excellent torque reserves (≥15%), and stable operation even under heavy load. The wide economic operating range (700–1200 rpm) and a minimum fuel consumption rate of ≤188 g/kW•h make it exceptionally economical for long voyages.
This engine is designed to fully comply with IMO II marine emission standards, ensuring lower emissions while delivering high output.
