W-Series Details
W Series Marine Diesel Engine
- 1. High-efficiency combustion: 4-valve cylinder head, P11 high-quality fuel pump, and twin turbochargers ensure greater airflow and complete combustion. Minimum specific fuel consumption is 193 g/kW·h and oil consumption is 0.3 g/kW·h, reducing operating cost.
- 2. Rigid & compact structure: WithPortal-type cylinder block and rear cover deliver compact design, high rigidity, and smooth operation. Strictly inspected and approved under MHI standards. Compared to peers, power is improved by 17% and torque reserve exceeds 4500 N·m.
- 3. Flexible configurations: Equipped with dual-layer high-pressure fuel pipes, optional single or dual flywheel housings, and fuel pump available in electric or manual adjustment, enabling wide adaptability across applications.
- 4. Simple design & easy maintenance: One-cylinder, one-head construction with straightforward appearance makes the engine reliable and easy to service.
