Marine auxiliary and genset engines like the 14V16/24DF often find their place in shipboard applications where reliable power generation and auxiliary functions are critical. This particular engine is designed to operate at 1200 rpm and produces 1540 kW of power using LNG or MDO as dual-fuel. With a bore of 160 mm and a stroke of 240 mm, the engine is configured in a V arrangement, featuring 14 cylinders. It adheres to IMO Tier II emissions standards, ensuring compliance with international marine regulations. Common maintenance issues include valve clearance adjustments, connecting rod bolt preload inconsistencies, and lube oil cooler stress due to improper tightening procedures. Additionally, monitoring coolant water quality and treating it properly is crucial to avoid operational damage. Fuel injection valve performance also needs regular checks to ensure optimal engine performance.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
