Main Engine 4-Stroke · Main Engines (4-Stroke)
Marine auxiliary engines are crucial components in ensuring reliable power generation on board vessels, and one such engine is the 6LDC-17 from Daihatsu. This robust 6-cylinder, L-configured engine operates at 900 RPM and delivers a substantial 780 kW of power, making it well-suited for a variety of maritime applications. The engine's bore measures 170 mm, with a stroke of 270 mm, providing a displacement of approximately 11,600 cc. It is designed to run on both Heavy Fuel Oil (HFO) and Marine Diesel Oil (MDO), offering flexibility in fuel selection. Maintenance considerations are an important aspect of ensuring the engine's longevity and performance. Service Bulletin GS05-18 highlights the need for improved atomization of the fuel injection nozzles, while GS05-21 emphasizes the critical nature of regular inspections and maintenance of the fuel injection valves. Additionally, vibration reinforcement is necessary on the fuel main pipe to prevent issues related to excessive movement, as noted in Service Bulletin GS05-19. The specific torque requirements for the mounting bolts of the fuel high pressure block are also crucial, as detailed in Daihatsu’s technical bulletins. These maintenance guidelines ensure that the 6LDC-17 operates efficiently and reliably, contributing to the overall performance and safety of the vessel.
