The Weichai Baudouin WP2.3NCD66E220 is a high-reliability, marine-certified inline-4 diesel engine designed for auxiliary generator drive and light propulsion in commercial vessels, fishing boats, workboats, yachts, and coastal craft. This 4-cylinder, 4-stroke, turbocharged and aftercooled engine with direct injection and mechanical governor produces 66 kW (90 hp) at 2,200 RPM, delivering up to 300 Nm torque in a lightweight 2.3 L displacement package, ensuring dependable performance in extreme marine conditions up to 1,000 m altitude.
Fuel Efficiency and Operational Economy: Rated at a minimum fuel consumption of 190 g/kWh (approx. 10 L/hour at full load on standard diesel), it achieves 15% better partial-load efficiency than competitors, supporting longer runtime, reduced refueling stops, and lower emissions for cost savings in fuel-intensive operations.
Consistent Power and Durability: Features wet cylinder liners, a 16:1 compression ratio, and bore/stroke of 89 × 92 mm for smooth torque delivery with ≤5% frequency stability. Handles 110% overload for 1 hour, protecting generators, navigation, and onboard electronics from surges, backed by a 30,000+ hour TBO for extended service life.
Marine-Engineered Toughness: Compact design at ~310 kg dry weight and 1,000 × 700 × 900 mm, compliant with IMO Tier II, SOLAS, and classification standards (ABS, DNV, CCS) for shock, vibration, and corrosion resistance. Idle speed of 750 r/min ensures quiet operation at ≤96 dB(A), prioritizing crew comfort in confined spaces.
Reduced Maintenance Focus: 500-hour service intervals, 10 L oil capacity, and ≤0.1 g/kWh oil consumption minimize downtime by 30%; durable dry filters and ergonomic layout enable swift onboard servicing. The 24V DC starting system guarantees starts to -20°C (heater optional), supported by Weichai’s global network for 24-48 hour parts availability.
Effortless Connectivity: Mechanical governor integrates with optional LCD digital panel for real-time monitoring, automatic alarm/stop, and CAN-bus diagnostics. Compatible with hybrid systems and paralleling for multi-engine scalability and seamless vessel integration.
Eco-Compliant Versatility: Meets IMO Tier II / China Stage II / EPA Tier 3 emissions without aftertreatment, optimized for 45°C ambient via seawater cooling with ≤10 kPa exhaust back pressure—ideal for humid, saline environments, streamlining certifications and enhancing long-term sustainability.
