  • OIL COOLING SYSTEM FOR SUPERCHARGED ENGINE
    Publication number: 20150361839
    Abstract: In an oil cooling system for a supercharged engine, coolant is introduced from a third coolant supply passage that branches from a first coolant supply passage into a coolant circulation passage of an oil cooler. The coolant has not cooled an engine and a turbocharger. By efficiently cooling lubricating oil (lubricating oil after lubricating supercharger) having lubricated the respective cooled portions of the turbocharger, oil-deterioration-suppressing effect can be improved even with the coolant of a small amount.
