Abstract
A cooling system for an internal combustion engine is provided. The cooling system comprises: a cooling passage provided within an engine housing of the engine, the cooling passage configured to carry a bulk flow of coolant to cool the engine housing, wherein the bulk flow of coolant within the cooling passage is driven by convection or a pump; and one or more additional cooling passages provided within the engine housing, each configured to introduce a flow of coolant into the cooling passage; one or more additional cooling passage pumps configured to pump coolant within the additional cooling passages; wherein the engine housing comprises one or more high temperature regions, which are at a higher temperature than one or more low temperature regions of the engine housing; and wherein the additional cooling passages are configured to direct the introduced coolant towards the one or more high temperature regions.
