A coolant bottle defines a first chamber and a second chamber fluidly coupled to the first chamber at a valve seat. The first chamber is fluidly coupled to a source of heated engine cooling fluid, while the second chamber is fluidly coupled to an engine water pump. A thermally responsive actuator is disposed within the first chamber, and has a thermally actuated sliding member having a valve seat engaging surface. The thermally actuated sliding member is movable from a first open position to a second closed position when the coolant is above a first temperature. The thermally responsive actuator is disposed within the first chamber.

A method is provided for operating an internal combustion engine (ICE), typically together with a vehicle. A corresponding ICE and a related computer program product are also provided.

A cooling system for an internal combustion engine of a motor-vehicle presenting a circuit for a coolant of the engine. The circuit includes a thermally insulated tank for the coolant of the engine, connected to an outer portion of the cooling circuit. The tank is arranged in the circuit to retain a defined quantity of coolant at a temperature above the ambient temperature when the engine is inactive, and for causing this quantity of coolant to flow, at a temperature above the ambient temperature, into the cooling circuit of the engine, after a subsequent start of the engine, during an engine warm up stage. The circuit also includes an expansion vessel connected to the outer circuit portion of the coolant of the engine. The expansion vessel has a thermally insulated body and constitutes the thermally insulated tank for the engine coolant.

A controller includes a forced-induction-device controlling section, an obtaining section that is configured to repeatedly obtain a temperature of the coolant in the intake-air cooling system, a determining section that is configured to determine whether the temperature obtained by the obtaining section is higher than or equal to a forced-induction limiting control starting temperature. On condition that the temperature of the coolant has risen to a value at which the determining section determines that the temperature obtained by the obtaining section is higher than or equal to the forced-induction limiting control starting temperature, the forced-induction-device controlling section starts a forced-induction limiting control to lower a forced-induction pressure. In the forced-induction limiting control, the forced-induction-device controlling section increases an extent of limiting of the forced induction as the temperature obtained by the obtaining section becomes closer to the boiling point.

An engine assembly (10) for a propeller-driven aircraft is disclosed, the assembly including an engine (11), a drive shaft (13) driven by the engine (11), and a radiator (20) comprising an aperture (24) for receiving the drive shaft (13), the aperture (24) being located such that the radiator (20) substantially circumferentially surrounds the drive shaft (13). The aperture (24) may take various forms, such as a hole within the interior of the radiator (20) or a blind slit formed within the radiator (20).
