Catalytic Converter

Print

The converter acts together with the closed-loop air/fuel ratio control system (See Section 5), and, based on the oxygen sensor signal, reduces the level of nitrogen oxide (NOx), hydrocarbons (HC) and carbon monoxide (CO).

This unit is filled with a catalyst to oxidize hydrocarbons and carbon monoxide in the exhaust gasses.

MAINTENANCE



  1. Check the core for cracks and damages.
  2.  
  3. If the idle carbon monoxide and hydrocarbon content exceeds specifications and the ignition timing and idle mixture are correct, the converter must be replaced.
