Patent number: 5743242Abstract: A heating device for use in the cylinder head of an internal combustion engine for heating the air/fuel mixture entering the cylinder head from the intake manifold. The heating device includes a frame or mounting member supporting an electric heating element having a plurality of resistance ribbons coupled to the mounting member by a plurality of mounting posts preferably formed by a plurality of threaded bolts. A power source may be electrically connected to one end of the heating element thereby providing an electric current which passes through the resistance ribbons. A securing arrangement, including a plurality of nuts threaded to cooperate with the threaded bolts and a plurality of conducting and insulating spacers disposable on the bolts, are provided to separate and rigidly couple the resistance ribbons to the mounting posts as a result of the compressive forces generated by the tightening of the bolts relative to the threaded nuts.Type: GrantFiled: January 4, 1996Date of Patent: April 28, 1998Assignee: Phillips & Temro Industries Inc.Inventor: Jan P. Thimmesch

Patent number: 5595164Abstract: A heating device for use in the cylinder head of an internal combustion engine for heating the airflow entering the cylinder head from the intake manifold. The improved heating device includes an electric heating element coupled to a frame which includes a perimeter mounting member and a recessed body portion. An aperture is formed in the recessed body portion to accommodate a terminal assembly that is adapted to pass through said aperture and a bore formed in the cylinder head. A power source may be electrically connected to the portion of the terminal assembly that extends beyond the cylinder head. The improved heating device allows the heating element to be recessed into the cylinder head thereby permitting the cylinder intake airflow to be heated without significantly increasing the distance between engine parts located above and below the heater.Type: GrantFiled: June 22, 1995Date of Patent: January 21, 1997Assignee: Phillips & Temro Industries Inc.Inventor: Jan P. Thimmesch
