The Weichai Baudouin WP4CD100E200 is a high-efficiency, marine-certified inline-4 diesel engine designed for auxiliary generator drive 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 90 kW (121 hp) at 1,500 RPM (50 Hz) or 100 kW at 1,800 RPM (60 Hz), delivering up to 580 Nm torque in a lightweight 4.5 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 195 g/kWh (approx. 13.5 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 105 × 130 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 ~450 kg dry weight and 1,200 × 800 × 1,000 mm, compliant with IMO Tier II, SOLAS, and classification standards (ABS, DNV, CCS) for shock, vibration, and corrosion resistance. Idle speed of 650 ±30 r/min ensures quiet operation at ≤100 dB(A), prioritizing crew comfort in confined spaces.
Reduced Maintenance Focus: 500-hour service intervals, 15 L oil capacity, and ≤0.2 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 / 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.
