<p>SELF-CONTROLLED VAPOR HEAT CAPSULE FOR ENGINE INTAKE MIXTURE HEATING An internal combustion engine is provided with a vapor heat capsule that utilizes a vaporizable heat transfer fluid to conduct heat from the engine exhaust gases to a hot plate for heating the intake air-fuel mixture. The rate of heat transfer and temperature of the heated surface are controlled by selection of a heat transfer fluid, the volume of fluid used and design parameters of the heat capsule to obtain, upon vaporization of all the fluid within the capsule, a fluid boiling and condensing temperature of a predetermined value below the coking temperature of the fuel. The rate of heat flow through the capsule is varied automatically in response to the cooling effect on the hot plate of heating air-fuel mixture and vaporizing varying amounts of liquid fuel droplets.</p> |
