An ignition module that is adapted to be secured to an internal combustion engine. The module has a plastic housing and a metallic cover that is adapted to be secured to an engine. A plurality of ignition coils are located within the housing and cover. The lower wall of the plastic housing has conductors embedded therein that electrically connect the secondary windings of the coils to electrical connector assemblies that are carried by the housing and which are adapted to slip over the spark plugs of an engine. The connector assemblies include means for making an electrical connection to the terminals of the spark plugs. The ignition coils have laminated cores that are clamped between the housing and the cover. The cores directly contact the metallic cover so that the cores have a heat transfer path to the cover and are electrically connected to the cover.

Integrated direct ignition module

A coupling for connecting the end of the camshaft of an internal combustion engine to the drive shaft of an ignition distributor. The coupling comprises a drive coupling member that is fixed to the drive shaft of the ignition distributor. The coupling member has a pair of axially extending lugs that have surfaces that engage surfaces formed on a pair of lugs that extend axially from the end of the camshaft. A spring member is fixed to the coupling member which has a pair of curved spring portions that engage other surfaces on the camshaft lugs and which serve to prevent backlash between the shafts.

Resilient anti-backlash shaft coupling

A projection having contoured sides that is carried by a member drivably engaging an internal combustion engine ignition distributor shaft is forced, upon assembly of the distributor to the engine, into an accommodating notch on the end of the engine camshaft adjacent the distributor shaft. The notch in the camshaft has substantially plane sidewalls that taper substantially equally inwardly at such an angle that each may tangentially engage a respective contoured side of the projection.
