1. An intake manifold and alternator system for a multicylinder internal combustion engine, comprising:
- a manifold having a plurality of passages for conveying intake charge to a plurality of cylinders of said engine and at least one primary coolant passage permitting the flow of engine coolant through the manifold, said manifold further comprising a generally cylindrical cavity adapted for housing an alternator therein, with the central axis of said cavity being parallel to the crankshaft of the engine;
an alternator driven by an endless belt powered by the crankshaft of said engine, with said alternator having a generally cylindrical outer body housed within said cavity; and
an alternator cooling circuit comprising a secondary coolant passage within said manifold for conducting coolant from said primary passage to a generally annular passage formed by said outer body and said cavity, and a discharge passage for conducting coolant from said cavity.

Abstract
An intake manifold and alternator system for an internal combustion engine includes a manifold for conveying intake charge to a plurality of cylinders of an engine and an alternator driven by the engine, with the alternator being housed within a cavity formed within the manifold. Passages conduct liquid coolant from the manifold to the alternator for the purpose of dissipating heat arising within the alternator.
