Two technicians are describing high- and low-pressure exhaust gas recirculation systems. Technician A says that non-cooled, high-pressure EGR flow dominates at low speed, low load conditions and transitions to more flow from the cooled, low-pressure EGR circuit. Technician B says that with an air intake throttle located downstream or after the EGR valve, the throttle plate can open and close to change the pressure differential. Who is right?
A)A only"
B)B only"
C)Both A and B
D)Neither A nor B"
