Power range: 4350-77400kW
Applications: bulk carriers, container ships, oil tankers, engineering vessels, etc.
The RT-flex, W-X, and dual-fuel DF series of marine low-speed engines utilize full electronic control and high-pressure common rail systems to flexibly manage fuel injection and exhaust valve actuation.This effectively reduces operational costs and ensures full compliance with emission regulations across different phases.
Their optimized power and rotational speed make them widely adaptable to various sizes and types of vessels, including bulk carriers, container ships, oil tankers, and engineering ships.
