СИСТЕМА СНИЖЕНИЯ ТОКСИЧНОСТИ ОТРАБОТАВШИХ ГАЗОВ ДЕТАЛЬНОЕ ОПИСАНИЕ

  1. FUNCTION OF MAIN COMPONENTS

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

      Component Function
      Exhaust Emission Control System ECM Determines an optimal fuel injection volume based on the signals from various sensors.
      Evaporative Emission Control System ECM Sends signals to the No. 1 vacuum switching valve assembly (VSV for EVAP) to control the purge flow.
      Charcoal Canister Contains activated charcoal to absorb the fuel vapor that is created in the fuel tank assembly.
      Vacuum Switching Valve Assembly No. 1 (VSV for EVAP) Open 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. Charcoal Canister

      1. The charcoal canister is integrated in the fuel suction with pump and gauge tube assembly.

  2. OPERATION

    1. Evaporative Emission Control System

      1. Based on the signals from various sensors, the ECM opens and closes the No. 1 vacuum switching valve assembly (VSV for EVAP). Thus, it controls the purge flow of evaporative emissions (HC) in the charcoal canister in accordance with the engine conditions.
