At what temperature do catalytic converters work efficiently?

Catalytic converters work at approximately 400-600 °C, which means two things:

  • There is a risk of fire. For example, it can be hazardous to park on a lawn with dry high grass, as catalytic converters are usually placed on the vehicle's undercarriage.
  • They are ineffective during cold starts – therefore use an engine pre-heater.
