ABSTRACT:
In an engine wherein the coolant is boiled and the vapor thereof used as a vehicle for removing heat, engine load is sensed and a fan, or like device, suitably operated to cool a radiator in a manner that the rate of vapor condensation therein is controlled to cause the pressure (and therefore the temperature) prevailing in the coolant jacket to rise to a level which promotes fuel economy during so called "urban cruising" and caused to drop for high speed and/or high load (e.g. hill climbing) to improve charging efficiency, avoid engine knocking etc. When the engine changes from high speed/load operation to "urban cruising", the rate of condensation in the radiator is maintained at that suitable for high speed/load operation for a short period to remove the heat accumulated in the engine and obviate a sudden temperature and pressure increase in the cooling system which would otherwise tend to occur upon the switch to "urban cruising" control.
