ABSTRACT:
A fuel evaporation device for enhancing fuel evaporation in an automotive fuel supply system without excessively interfering with the flow of an air-fuel mixture to an automotive engine is particularly adapted for use where the system has an air-fuel passage directing the air-fuel mixture into an intake manifold and where fuel tends to condense on the walls of the passage during engine start up on cold days. The device has a multi-ply gasket with a central opening to be mounted on the engine between the air-fuel induction passage and the manifold, has a first terminal with a ring-shaped part mounted between the plies of the gasket to extend around a major part of the gasket opening, has a second terminal mounted in a common plane between the plies to extend into the opening in the remaining part of the opening periphery, has a tube with a flange at one end extending around a corresponding major part of its periphery secured to the ring-shaped part of the first terminal so that the tube is adapted to intercept fuel condensed on the passage walls and extends into the manifold, has a self-regulating electrical resistance heater electrically connected to the opposite end of the tube to be disposed within the manifold spaced from the opposite tube end in the path of the air-fuel mixture being directed into the manifold to receive condensed fuel from the opposite tube end, and has a conductor electrically connected between the heater and the second terminal for connecting the heater in an energizing circuit.
