Oil supply system for internal combustion engine, has two pumps for supplying oil to lubrication system and nozzles, respectively, where lubrication system includes supplementary by-pass circuit connecting one pump to nozzles

摘要

The system has a pump (16) for supplying oil to a lubrication system (20) of an internal combustion engine of a motor vehicle. Another pump (18) supplies oil to nozzles (30) for cooling pistons. The lubrication system includes a supplementary by-pass circuit connecting the pump (16) to the nozzles. The by-pass circuit connects the lubrication system to the pump (18) for supplying the nozzles.
