Main Engine 4-Stroke · Main Engines (4-Stroke)
Medium-speed marine auxiliary diesel engines like the 12VDK-36 are commonly found on ships where reliable power generation and propulsion support are critical. This engine operates at a rated power of 7200 kW, achieving this output at 600 RPM with a fuel type of HFO/MDO. It features a V-configuration with 12 cylinders, each having a bore of 360 mm and a stroke of 480 mm. The engine is designed to handle heavy-duty marine applications and is verified to meet the requirements for medium-speed engines, although specific details like bore and stroke dimensions for the DK-36 series are inferred based on naming conventions and analogous designs. Maintenance checks include ensuring the fuel injection pump tappet adjustment screw remains tight to prevent loosening, which is a common issue observed in the DK-28 and DK-32 engines. Additionally, regular maintenance of the engine-driven cooling water pump is essential for the DK-26, DK-28, DK-32, and DK-36 series engines. Special attention is also required for the valve assembly, particularly for intake and exhaust valves, to ensure critical tolerance is maintained, as per Daihatsu's service documentation.
