Abstract: An air intake heater system includes an air heater adapted to be positioned in communication with an intake passageway of an engine and a controller. The controller is operable to repeatedly supply current and discontinue the supply of current to provide a desired energy output of the air heater.

Abstract: An air intake heater for use in a motor vehicle has an engine with an engine block and an intake manifold defining an air passageway. The air intake heater includes a gasket having a conductor plate disposed between two non-conducting sealant layers, the conductor plate has at least one inner terminal adapted for positioning inside the air passageway and at least one outer terminal adapted for positioning outside the air passageway. A heating element is coupled to the gasket and adapted to be disposed within the air passageway, wherein the inner terminal is electrically coupled to the heating element and the outer terminal is electrically coupled to a power source.

Abstract: A dual media connector having a first media wire and a second media wire disposed within each of a housing insert, a rear seal, a conduit and a grommet, the first and second media wires adapted to electrically interconnect first and second communications devices with external communication signals.

Abstract: A heater for heating air in an intake passage of an internal combustion engine. The heater includes a heating element coupled to a first holder and a second holder. The heating element has a preselected resistance corresponding to plurality apertures formed therethrough. A second embodiment includes a heating element positioned within a housing. The heating element includes a plurality of selectively removable slugs. After removal of one or more of the slugs, the electrical resistance of the heating element increases.

Abstract: A heater for the intake manifold of an internal combustion engine that includes a first heating element having a first end and a second end, a second heating element having a first end and a second end, and a first bolt assembly that mechanically couples yet electrically isolates the first end of the first heating element from the first end of the second heating element. In the heater, the first and second heating elements are electrically connected in series and the first end of said first heating element is electrically connected to the first bolt assembly. The first bolt assembly also electrically connects the first end of the second heating element to ground.

Abstract: An air intake for an internal combustion and a heater for use in the air intake includes a mounting flange, a frame coupled to the mounting flange and having a pair of opposed upright walls each defining an upstream face and a downstream face relative to a direction of airflow, a heating element assembly, and coupling means located on or between the upstream and downstream faces for connecting the heating element assembly to the frame and limiting movement of the heating element assembly relative to the frame.

Abstract: A heater for an internal combustion engine includes a first holder, a second holder and a heating element positioned between the first and second holders. The heater further includes a frame defining a channel. The frame includes a plurality of prongs extending inwardly toward the channel that retain the holders in a first direction relative to the frame.
