Maintaining optimal performance and reliability is crucial for Wärtsilä’s 18VW20 engine. Regular inspections are essential to prevent common failures. For instance, continuous monitoring of balancing shaft temperature through Wärtsilä’s specialized system can help avoid costly damage. Additionally, ensuring proper ventilation by checking the function of pneumatic exhaust valves and upgrading older models to hydraulic versions is critical for longevity. Careful inspection of piston rings and cylinder liners every 4-8 weeks prevents severe wear. Proper fuel injection system maintenance, including inspecting nozzles for erosion, also ensures efficient operation. Regular checks can significantly extend the lifespan of this powerful engine, keeping it running smoothly at 1200 RPM or higher.
