Abstract
An intake manifold for an internal combustion engine, consisting of a flow channel enclosed by a wall. The wall (1) consists at least partly of electrically conductive, polymeric material and can be connected with a source of voltage (3) by means of connectors (2, 7), which are at a distance from one another, and heated by this voltage source.
Claims8
In an intake manifold for an internal combustion engine, consisting of a flow channel, which is enclosed by an electrically conductive wall and which can be heated in at least a part of its region by the wall, the improvement which comprises that the wall (1) consists at least in the aforementioned part of an electrically conductive, polymeric material and can be connected by connectors (2, 7), which are at a distance from one another, with a source of voltage (3) and heated by this source.
An intake manifold for an internal combustion engine comprising
- a wall defining a flow channel, said wall comprising a part of electrically conductive polymeric material, said part having an inside facing said channel and an outside opposed from said channel,
- a pair of electrical connectors connected to said part, one of said connectors being remote from said engine, the other connector being proximate said engine, whereby,
- upon connecting a voltage source across said connectors, said part can be heated.
