Turbocharging added a significant boost in power and efficiency, making these models suitable for heavier workloads and larger vessels.
Features of Turbocharged Models:
- Enhanced horsepower, often exceeding 300 HP.
- Improved fuel efficiency compared to non-turbo versions.
- Suitable for vessels with higher power demands, such as mid-sized fishing boats and small cargo vessels.
3. Turbo-Intercooled Models
Intercooled models incorporated an intercooler to cool the air entering the combustion chamber, further increasing efficiency and performance.
Features of Turbo-Intercooled Models:
- Increased power output, ranging between 375–450 HP.
- Improved thermal efficiency for long-duration operations.
- Suitable for tugboats and larger commercial vessels.
4. Turbo-Aftercooled Models
Turbo-aftercooled configurations represented the pinnacle of the 6V92 lineup, offering the highest power output and efficiency. These models used aftercoolers to further reduce air temperature after compression, ensuring optimal combustion.
Features of Turbo-Aftercooled Models:
- Horsepower exceeding 450 HP, with some configurations reaching up to 500 HP.
- Designed for heavy-duty applications such as large fishing vessels, tugs, and offshore supply boats.
- Enhanced durability for high-load operations.
