Device to preheat a fuel mixture
A device is described to preheat fuel being furnished to an engine comprising a metal body to be mounted in a cavity in a wall of an intake manifold. The body has a bottom with an outer surface to be exposed to fuel in the intake manifold for heating the fuel and with an inner surface and has a side wall extending around the inner surface. A means is included for securing the body to the intake manifold. An electrical resistance heater pill of a material of positive temperature coefficient of resistivity is disposed in thermally conducting relation to the inner surface of the body bottom, and a contact bearer has a portion of electrical insulating material secured to the body holding an electrical conductor in resilient electrical contact with the heater pill, characterized in that the body side wall cooperates with the inner surface of the bottom of the body for defining a body cavity. Detents are provided on the body side wall in spaced relation to each other, and the contact bearer has a configuration corresponding to the body cavity and has the electrical conductor secured thereto. The contact bearer has a configuration to be received within the body cavity and rotated under the detents for removably attaching the contact bearer in the body cavity with the electrical conductor in resilient electrical contact with the heater pill.
