Multi-temperature lubrication system for internal combustion engine of motor vehicle, has temperature controllers formed such that temperature of fluid in one of lubrication circuits is different from temperature of fluid in other circuit

摘要

The system has a pump (12) for supplying lubrication fluid e.g. oil, to two lubrication circuits (14). The fluid circulates in each circuit till attaining a component (15) e.g. piston, that is associated with an internal combustion engine. Lubrication fluid temperature regulation units i.e. temperature controllers (18), are formed such that the temperature of the fluid circulating in one of the circuits is different from the temperature of the fluid circulating in the other circuit.
