    Abstract: A secondary air injection system supplying some of air introduced into an intake manifold to an exhaust manifold may include: an electric supercharger compressing air introduced through an air duct; throttle valves installed at an upstream of the intake manifold and controlling the amount of air introduced into the intake manifold by controlling the amount of air passing through the electric supercharger; secondary air valves installed on branching paths branched from intake, lines that link the electric supercharger and the throttle vales and controlling the amount of air for secondary air injection; and an injector that post-combusts exhaust gas discharged from an engine by injecting secondary air passing through the secondary air valve to a runner of the manifold.
