Main Engine 4-Stroke · Main Engines (4-Stroke)
Regular maintenance and addressing common failures are crucial for the reliable operation of marine diesel engines like the Daihatsu 6LDK-28. This engine is part of the robust DK-28 family, designed to handle the demands of marine propulsion with a 6-cylinder, 4-stroke configuration. It features a bore of 280 mm and a stroke of 390 mm, generating a power output of 2310 kW at 720 rpm. The engine is capable of running on both MDO and HFO fuels, adhering to IMO Tier II/III emission standards. Common maintenance issues include connecting rod bolts hitting the frame in three-piece connecting rod models, requiring careful monitoring and adjustment. Additionally, chromium plating may be necessary for ring groove wear on certain models, and regular renewal of pulse absorbers is recommended to ensure reliability. Crankshaft journal wear can also be an issue in high-service applications, with on-site grinding documented as a restoration method.
