Lubricating oil circuit having a lubricant-zeolite contact interface and using the zeolite to reduce the oxidation of lubricating oil

摘要

The lubrication circuit (1), for an internal combustion engine, has a cartridge (6) placed in a flow area of the lubricating oil (22) and which contains a porous zeolite assembly for contacting with the less partial flow of oil with said zeolite. The porous assembly has zeolite particles of nanometric size between 10 nm and 60 nm which are provided with channels or large pores having a size greater than 0.6 nm. These zeolite particles can be integrated into a layer or a reservoir member present in an oil filter (3) of the circuit (1). A slowdown effect on the aging of the lubricating oil can then be obtained. Figure for the abstract: F i gure 2
