Abstract
A heater is provided for use in conjunction with a fuel passageway, such as a cold start passageway, in an internal combustion engine in which fuel is injected into the passageway. The heater includes a tubular housing which is insertable into the passageway so that fuel flow through the passageway flows through the interior of the housing. A plurality of heater assemblies are also provided wherein each heating assembly has a capsule and at least one electrical heating element thermally coupled to its associated capsule. The capsules are secured to the housing so that the capsules are circumferentially spaced from each other around the housing. In one embodiment, the capsules are secured to an interior surface of the housing so that one surface of each capsule is open to the passageway. In a second embodiment, the capsules are secured around the outer periphery of the housing and each heating element is thermally connected to the housing.
