Main Engine 4-Stroke · Main Engines (4-Stroke)
Regular maintenance and monitoring of critical components are essential for ensuring optimal performance and longevity of the Caterpillar 12V3412E engine. This 12-cylinder, 4-stroke V-configured engine generates 960 kW of power at 2100 rpm and is designed to run on MDO fuel. Introduced in 1994, it has a robust design with high-efficiency turbocharging and direct fuel injection. Caterpillar offers an optional crankshaft bearing condition monitoring system to detect potential wear issues early, and the high-efficiency turbocharger is known for its low wear rate. However, operators must manage the quality of heavy fuel oil (HFO) to avoid contamination and corrosion issues, particularly in seawater-cooled systems where anode protection and regular flushing are recommended.
