Diesel engines like the Wärtsilä 8LW32-GS-50Hz are commonly found in shipboard applications where reliable power generation and propulsion are critical. This engine operates at 750 RPM and is designed to run on Heavy Fuel Oil (HFO), Light Fuel Oil (LFO), Marine Diesel Oil (MDO), and ultra-low sulphur fuel, making it versatile for various marine environments. With a power output of 2640 kW, it is well-suited for large vessels such as cargo ships and offshore platforms. The engine features a 4-stroke, non-reversible, turbocharged, intercooled, and direct fuel injection configuration. It complies with IMO Tier II emissions standards, ensuring environmental compliance. The engine has eight cylinders with a bore of 320 mm and a stroke of 400 mm, delivering a specific power output of 580 kW per cylinder. Common maintenance issues include sticky injection pump racks during HFO operation, wear and carbon deposits on exhaust valve seats, and camshaft gear wear, which require regular monitoring and timely replacement.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
