Abstract

PURPOSE: To enable the supply of secondary air in an exhaust path by utilizing the negative pressure which is produced in an exhaust port when an exhasut valve and an intake valve are opened at the same time and the pulsation of an exhaust gas pressure an obviating the need for an air pump.
