Two Technicians Are Describing High-Pressure Cooled (HP-CEGR) EGR Systems

Multiple Choice

Two technicians are describing high-pressure cooled (HP-CEGR) EGR systems. Technician A says that an HP-CEGR system does not use a throttle plate to draw exhaust in, instead a VGT pressurizes exhaust gases high enough to push exhaust into the boosted air intake. Technician B says that cooled EGR gas redirected from the exhaust manifold is pressurized to overcome intake boost pressure called high-pressure cooled EGR (HP-CEGR) . Who is right?

A) A only"
B) B only"
C) Both A and B
D) Neither A nor B"
