Make: Wartsila
Type: 6L20
The Wärtsilä 6L20 is a six-cylinder, inline marine/industrial diesel engine renowned for its reliability and strong performance in generator or propulsion roles. With a bore of 200 mm and stroke of 280 mm, it delivers around 1,080-1,200 kW (depending on speed and configuration) and operates at approximately 1,000 RPM, making it a powerful option for continuous-duty applications.
The engine offers excellent fuel flexibility, able to handle a wide range of fuel viscosities including heavy fuels, with design features that support durable components, efficient cooling, and long overhaul intervals.
For maintenance and overhaul purposes, having access to major spare parts is critical to preserving the Wärtsilä 6L20’s performance. Components such as cylinder liners and heads, pistons, connecting rods, crankshaft, valves, fuel injection pumps, turbochargers, and gasket sets are essential.
Genuine spares help restore power output, reduce vibration, maintain fuel efficiency, and extend the useful life of the engine. Together with proper inspection and maintenance, these parts ensure the 6L20 continues to deliver dependable service in heavy-use scenarios.
