Abstract
To provide for an extended heat dissipating surface to an ignition coil, the coil is combined in a single housing structure with electronic control components, and located in a well or trough or tub-like housing structure, surrounded by a resin potting compound, but separated from the housing structure which, preferably, is a metal pressure or investment casting by a cushioning layer to provide for compensation of shrinkage, or expansion, upon differential changes between the housing and the coil due to heating, the extended housing structure also enclosing electronic circuit structures such as power components and printed circuit boards to thereby permit electrical association of the components with the ignition coil while, simultaneously, providing for a larger housing structure with increased heat dissipation capability.
