Abstract
An engine cover with integrated ignition system components that provides a protective enclosure for ignition coils in a distributorless ignition system of an internal combustion engine. The cover serves as a cylinder head cover for sealing over the valve assembly of the engine and for that purpose includes a plastic housing having an upper wall and side walls that extend downwardly to a perimeter mounting surface of the housing. The housing includes a unitary compartment that is located above the upper wall. The ignition coils are mounted within the compartment and are electrically connected via terminals to high voltage leads that are embedded in the upper wall and that extend laterally to a corresponding second group of terminals located at the lower surface of the upper wall. These terminals are positioned so as to electrically connect to the engine spark plugs when the cover is installed on the engine.
