Secondary air supply device for internal combustion engine and control method of the secondary air supply device
Abstract:
A secondary air supply device for an internal combustion engine includes: an electric air pump that supplies secondary air into an exhaust pipe of the internal combustion engine; a controller that controls actuation of the electric air pump according to an operating state of the internal combustion engine; and an air flow mechanism that rotates the electric air pump by causing air in the electric air pump to flow. The controller uses the air flow mechanism to rotate the electric air pump before energizing the electric air pump.
