Overview
The Wartsila W26 liner is a high-quality flanged cylinder liner made for the Wartsila 26 series medium-speed diesel engines, which are known for powering ships and generating electricity. It has tangential water flow for better cooling and an anti-polishing ring that scrapes carbon off the top surface of the piston. This cuts cylinder wear by up to 50% and uses less lubricating oil. This strong part makes sure that combustion is at its best, emissions are low, and the service life is long in tough offshore and vessel operations.
