ABSTRACT:
In order to optimize (with respect to engine load) the temperature and/or pressure prevailing in the coolant jacket of an engine wherein the coolant is boiled and the vapor thereof used as a vehicle for removing heat, the load is sensed and a fan or like device suitably controlled to cool the radiator in a manner that the temperature and/or pressure prevailing in the coolant jacket is raised to a suitable level to promote fuel economy during urban cruising and reduced for high speed and/or high load (e.g. hill climbing) to avoid engine knocking and/or piston seizure.
