Patent ID: 8096289

Claim:
An apparatus to separate an air compressor air intake in an internal combustion engine from an exhaust gas recirculation (EGR) gas, the apparatus comprising: a connector adapted to receive intake air and including an exit port and an entry port for an EGR gas; and an air intake elbow connected to the air intake connector, the elbow adapted to receive intake air and including: a first passage adapted to route a first portion of the air to the air intake connector to be mixed with the EGR gas; and a second passage adapted to route a second portion of the air to the air intake connector and out said exit port of the air intake connector to an air compressor, wherein the second passage is attached to the elbow and extends through a bend in the elbow; wherein the air intake connector includes a connector passage that mates with the second passage at about the center of the first passage and mates with the exit port, wherein the connector passage substantially isolates the second portion of air from the EGR gas, the connector passage including a bend adapted to route the second portion of air to the exit port of the air intake connector.
