Abstract

An apparatus for controlling a low-pressure EGR system may include a driving information detector configured to detect a vehicle driving state, an EGR amount detector configured to detect an amount of external EGR controlled by a low-pressure EGR valve, and a controller configured to control the low-pressure EGR valve and intake and exhaust valves of an engine, based on the result detected by the driving information detector and the EGR amount detector, wherein the controller controls timings of the intake and exhaust valves to decrease an amount of internal EGR introduced into a cylinder through an exhaust port for a predetermined time when the amount of external EGR is decreased.
