EMISSION CONTROL SYSTEM


  1. CONSTRUCTION


    1. The air switching valve assembly is operated by a solenoid coil to control air injection and prevent back-flow of exhaust gas. The opening timing of the valve is synchronized with the operation timing of the air pump assembly.

    2. An air pressure sensor is built into the corresponding air switching valve assembly.

    3. The air switching valve assemblies for bank 1 and bank 2 have the same basic structure and function.
