ABSTRACT:
Heating apparatus for the air-fuel mixture of a vehicle engine including a perforated grid placed across the flow of the air-fuel mixture. The grid is spaced downward from the outlet of the carburetor. A bypass housing formed of permeable screen material may be placed with an open inlet end registered with the carburetor outlet and with an open outlet end registered with the face of the heating grid. During engine start and idle modes with or without use of a choke all of the fuel-air mixture passes through the grid. During off-idle engine modes which require substantially greater flow rates, a portion of the mixture may bypass the grid and pass through the permeable walls of the bypass housing.
