EMISSION CONTROL SYSTEM


  1. FUNCTION OF MAIN COMPONENTS


    1. The main components of the evaporative emission control system are as follows:

      Component Function
      ECM Controls the purge VSV in accordance with the signals from various sensors, in order to achieve a purge volume that suits the driving conditions.
      Charcoal Canister Assembly Contains activated charcoal to absorb the fuel vapor that is created in the fuel tank assembly.
      Purge VSV (Vacuum Switching Valve Opens in accordance with the signals from the ECM when the system is purging, in order to send the fuel vapor that was absorbed by the charcoal canister assembly into the intake manifold.

  2. SYSTEM CONTROL


    1. Evaporative Emission Control System


      1. The ECM controls the purge flow of the evaporative emission (HC) from the charcoal canister assembly in accordance with engine conditions.
