  • Internal combustion engine coolant flow
    Patent number: 7263954
    Abstract: A cooling system for an internal combustion engine 1 is disclosed in which an electronically controlled flow control valve 9 is used to control the flow of coolant exiting the engine 1. The electronically controlled flow control valve 9 is able to control the cooling of the engine 1 irrespective of the speed at which a pump 2 used to urge coolant to flow into the engine 1 is rotated by a drive belt 3 connected to an output 4 from the engine 1.
