STANDARD AND OPTIONAL ENGINE DESIGN. The engines are fitted with necessary relief valves in the crankcase doors. This description is in general related to standard engine design and standard engine fitted auxiliary equipment. In addition optional engine design and optional engine fitted equipment are described. For ancillary engine systems with equipment not fitted on engine, see relevant parts in the manual. Crankshaft The crankshaft is a forging of chromium-molybdenum steel. It has bolted-on counter-weights to balance inertia forces. A torsional vibration damper and / or rotating mass is...

Part 1.01 Pistons The pistons are of the composite type, with nodular cast iron skirts and forged steel crowns. They are cooled by oil from the main lubr. oil system, which is led to the pistons through the connection rods. The gudgeon pin bearing has a “stepped” design that gives a large bearing surface in direction of the firing load. Each piston has two compression rings and one spring- loaded oil control ring, all especially adapted for a controlled lubr. oil consumption. The piston rings are chromium plated, the 1st ring with a special chrome-ceramic coating for extra wear resistance....

Part 1.01 The high-pressure pipes to the nozzles are shielded, with drain to waste oil tank via an alarm sensor. Large covers enclose the fuel injection system completely for safety reasons, in case of any leakage and to keep it well tempered. For heavy oil duty, the booster pump as well as the fuel oil filter are separately fitted. The fuel oil injection valves are temperature controlled by means of lubr. oil from the engine system, and which is heated by a heat exchanger connected to the jacket water system. Standard engines are designed for start-stop on heavy fuel oil. The diesel...

Part 1.01 Engine-driven sea/low temp. fresh-water pump is standard, while electrically driven is an option for auxiliary engine. Main lubricating oil system The main lubr. oil system is as standard based on wet sump and is completely mounted on the engine. The lubr. oil pump is engine driven by a gear train from the crankshaft in the front end of the engine. A manually adjustable pressure regulating valve is placed just down-stream of the pump, with a pressure feed-back from the aft end of the engine. The valve gear is lubricated from the main lubr. oil system via a pressure reduction...

Part 1.01 Power output / Propeller design Propeller design depends upon vessel type and duty. If the fixed propeller solution is chosen, it should be designed so that it absorbs 85% of the maximum continuous output of the engine at normal speed when the ship is on sea trial, at specified speed and load. For ships intended for towing (TUGS), the propeller can be designed for 95% of MCR of the engine at nominal speed for bollard pull or at towing speed.
