During operation of engines (especially trunk type engines) the lubricating oil will gradually be contaminated by small particles originating from the combustion and, in particular engines operated on heavy fuels which will normally increase the contamination due to the increased content of carbon residues and other contaminants (about four stroke lubricating system you can read…
This is another on-demand post and its purpose is to explain the 4-stroke lubrication system from operational point of view. All running gear of the 4-stroke engine is forced lubricated by an engine-driven gear type pump which takes the oil from the engine sump tank. The same oil from engine sump tank is also provided…
Cylinder lubrication is load dependent and the system is designed to deliver a specified quantity of lube-oil in the cylinder liner, of which main purpose is to reduce corrosion and friction and to increase the sealing effect between piston ring and the cylinder liner. Because today’s cylinder oils have complex chemistry, the particular feed rate…
