Filed:

May 1, 2012

Appl. No.:

13/460968

Inventors:

ALBERT A. SKINNER - WATERFORD MI, US
HARRY O. LEVERS - CLARKSTON MI, US
ANDRE V. SCAFF - LAKE ORION MI, US

Assignee:

DELPHI TECHNOLOGIES, INC. - TROY MI

International Classification:

F02P 1/00

US Classification:

123634

Abstract:

An ignition coil for an internal combustion engine includes a magnetically-permeable core extending along a core longitudinal axis, the core having a pair of end surfaces on axially-opposite ends thereof. The ignition coil also includes a primary winding disposed outward of the core, a secondary winding disposed outward of the primary winding, and a structure comprising magnetically-permeable steel laminations having a base and a pair of legs, the structure defining a magnetic return path. The core is disposed between the pair of legs such that the core longitudinal axis extends through the legs and the end surfaces face toward the legs and at least one of the end surfaces of the core is spaced apart from a respective one of the legs to define an air gap. The structure is over-molded with an over-molding material such that the over-molding material fills at least a portion of the air gap.

International Classification:

F02P 1/08

US Classification:

123605

Abstract:

An ignition coil for an internal combustion engine includes a magnetically-permeable core a primary winding disposed outward of the core, and a secondary winding disposed outward of the primary winding and inductively coupled to the primary winding. The secondary winding has a left secondary winding section and right secondary winding section. A first end of the left secondary winding section is in electrical contact with a first terminal for delivering a first spark-generating current to a first spark plug. A first end of the right secondary winding section is in electrical contact with a second terminal for delivering a second spark-generating current to a second spark plug. A second end of the first secondary winding and a second end of a the second secondary winding is connected to a third terminal for delivering a third spark-generating current to a third spark plug.
