Main Engine 4-Stroke · Main Engines (4-Stroke)
Designed with robustness and reliability in mind, the MaK 16VM43DF engine operates on a V-configuration with a 4-stroke cycle, delivering exceptional power output of 13920 kW at 500 rpm. This dual-fuel engine supports LNG and HFO, offering flexibility and efficiency in various marine applications. The engine features a bore of 430 mm and a stroke of 610 mm across its 16 cylinders. Its high-efficiency turbocharger is designed with a corrosion-free housing and operates without water cooling, enhancing durability and performance. Since its introduction in 1994, over 1600 units have been produced, with the majority used for propulsion systems. The engine’s legacy as a reliable and proven solution continues under Caterpillar Marine Power Systems. Common maintenance considerations include monitoring specific fuel oil consumption (SFOC) across different load ranges, ensuring high-quality HFO to prevent contamination risks, and regularly inspecting the crankshaft bearings and cooling system to avoid marine corrosion issues.
