ABSTRACT:
A friction-reducing lubricating-oil filter for Internal Combustion Engine and in which a solid-lubricant-feeding equipment is equipped on the lubricating-oil duct where the lubricating-oil has been finely cleaned and has not got to the friction parts, which is wholly sealed and is filled with solid lubricant, on which there are several holes evenly arranged; when the lubricating-oil flows over the outside surface of said solid-lubricant-feeding equipment and said holes, because the static pressure of the flowing liquid is lower, the solid lubricant in the solid-lubricant-feeding equipment is drawn out through said holes and mixes with the lubricating-oil. This friction-reducing lubricating-oil equipment doesn't need any other driving equipment and can transfer the solid lubricant to the friction parts without filtering out by the filter, and therefore is not only simple in structure, but also very effective in friction-reducing.
