An intake manifold for a multicylinder internal combustion engine includes intake runners for conducting air or air and fuel to intake ports formed in the engine cylinder head and an EGR passage formed in the manifold and extending generally parallel to the crankshaft of the engine. Secondary EGR passages extend from the EGR supply passage to intake runners or intake ports, and a coolant passage formed in the manifold extends generally parallel to the EGR supply passage and has a common wall with the EGR passage.

A noise reduction side-branch reactive silencer for use with the air induction system of an internal combustion engine. The side-branch reactive silencer is contained within a subframe interposed between the engine and a vehicle body. The subframe is a rigid structure and forms a reactive cavity therein. The subframe has a connector for communicating the reactive cavity with the air induction system of the vehicle. The connector is positioned along the subframe in accordance with the desired attenuation frequency.

A valve train for an overhead camshaft type engine includes a finger follower lever type rocker arm assembly. The lever is of lightweight stamped construction containing a pocket or recess in which is received a precision molded plastic bearing cup. The cup has a smoothly polished bearing surface for slidably receiving an axleless roller that is contained laterally within the insert and is rotated by the engine driven cam located above the roller for pivotally moving the lever to actuate the engine valves. The inclusion of the pocket in the lever assures lubrication of the parts at all times since it will collect and retain lubricant or engine oil during engine operation so that even during a lengthy shutdown, upon restart, the elements will be fully lubricated.
