Coolant from the engine cooling circuit 14 is supplied to a cooler 17 for the precompressed charge in dependence on the temperature of the charge or on a condition varying with that temperature. The cooler 17 is connected to the engine cooling circuit by flow and return pipes 18, 19, connected on opposite sides of a control valve 101 operated by a temperature responsive device 24 in the engine intake system. Valves, 104, 105, in pipes 18, 19 may also be controlled conjointly with the valve 101, which latter may be a butterfly valve, a piston slide valve, or a pivoted sector. Instead of being directly controlled by charge temperature, valve 101 may be controlled in response to the speed of an exhaust gas turbine driving the charge compressor, or in dependence on the engine fuel control means, or in dependence on an engine speed setting control.
