Abstract
An air-fuel mixture heating device for heating an air-fuel mixture supplied from a carburetor to an intake manifold includes an insulator mounted between the carburetor and the intake manifold and having a first air-fuel mixture passage communicating with the primary air-fuel mixture passage in the carburetor, an electric heater disposed in the first air-fuel mixture passage of the insulator for heating the air-fuel mixture, and a plurality of conductors embedded in the insulator and having portions connected to the electric heater and an electric power supply. The insulator has access holes extending to the portions of the conductors for allowing said portions to be joined to the electric heater therethrough. The access holes are filled up with masses of sealing resin after said portions are joined to the electric heater. The conductors extend on one side of a second air-fuel passage in the insulator which communicates with the secondary air-fuel passage in the carburetor, the conductors having outer ends projecting as terminals out of the insulator laterally of the second air-fuel passage or remotely from the first air-fuel mixture passage.
