ABSTRACT:
An accessory drive for an overhead cam internal combustion engine wherein the accessory may comprise a high pressure positive pump for a fuel injection system. The engine includes at least one camshaft that is rotatably journaled within a cam chamber formed by a main cylinder head member and a cam cover that is affixed to it. One end of this camshaft is journaled by a bearing cap that has a portion which extends forwardly beyond the cam chamber and which cooperates with the main cylinder head member to define a recess in which a portion of the housing of the accessory is contained and affixed. An accessory drive shaft extends through this mounting portion and is drivingly coupled to the camshaft end. If desired, this front bearing cap may also mount a timing sensor that will project through the cam cover.
