Abstract
A system of forcibly regenerating a gasoline particulate filter may include an exhaust pipe connected to the engine; a catalyst apparatus mounted on the exhaust pipe; first and second intake lines; first and second electric superchargers disposed on the first and second intake lines; a bypass line connecting a first point of the first supercharger and a second point of the second supercharger to each other; a first intake valve disposed at a downstream of the first point of the first intake line; a second intake valve disposed at an upstream of the second point of the second intake line; a bypass valve disposed on the bypass line; and a regeneration air line connecting the first intake line or the bypass line between the first electric supercharger, the first intake valve, and the bypass valve to the exhaust pipe between the catalyst apparatus and the gasoline particulate filter.
