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

#CMT# #/CMT# 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. #CMT#USE : #/CMT# System for supplying oil for an internal combustion engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The configuration of the supply system permits optimal adjustment of different pressure levels in the lubrication system and in the nozzles in a distinct, simple and safe manner, thus adjusting power consumed by the two pumps in an economic manner and reducing energy and fuel consumption. The arrangement of the pumps allows efficient supplying of the oil for different components, during malfunctioning of one of the pumps. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block representation of an oil supply system for an internal combustion engine. 12 : Oil sump 16, 18 : Pumps 20 : Lubrication system 22 : Electric motor 30 : Nozzles.
