Main Engine 4-Stroke · Main Engines (4-Stroke)
Maintaining optimal performance and reliability are paramount considerations for any marine operation. The Wärtsilä 7LW32SG engine is designed with these factors in mind, offering robust construction and a focus on key areas prone to wear and tear. This 7-cylinder, 320mm bore, 400mm stroke engine boasts a power output of 2345kW at 750rpm, fueled by LNG (Spark-Ignited). Its 4-stroke configuration includes turbocharging, intercooling, and direct fuel injection for efficient power delivery. Common maintenance points include addressing stickiness in the fuel rack (especially during HFO operation), monitoring exhaust valve seat wear, and inspecting camshaft gear backlash and timing gear condition. Proper bearing shell installation alignment is crucial due to the tribological pairing of tin-aluminium-on-chrome-iron. Fuel injection nozzle clogging, stemming from dirt, debris, or contaminated fuel, is another area requiring attention, with different nozzle types used for HFO and MDF installations.
