Product Advantages
- Safe and reliable. Inherently-safe design concept, double-wall piping structure design, dedicated GVU valve box (with CCS certificate) standard across the whole series, 1000-hour endurance test assessment, safer and more reliable.
- Optimised fuel efficiency. Optimized design of gas-engine-specific components and systems, combining simulation-based virtual development and test technology to optimize combustion chamber, cam phasing, uniform intake control per cylinder, turbocharger matching design and piston surface treatment, more rational structure and better fuel adaptability.
- Energy saving. Matched with a mature mass-applied control system, high-energy ignition, lean-burn and closed-loop oxygen control, more stable combustion and lower gas consumption rate.
- Smart maintenance. Upgraded intelligent instruments, real-time monitoring of engine data and whole-vessel positioning, intelligent fault alarm analysis, uploading to the smart cloud terminal, convenient fleet management, meeting the needs of intelligent ships.
