An oxidation catalyst on a diesel engine treats

  • A.Sulphur dioxide
  • B.Carbon dioxide
  • C.Carbon monoxide and hydrocarbons, including the soluble organic fraction
  • D.Oxides of nitrogen

Answer: C

A diesel runs lean, so there is ample oxygen for oxidation but no possibility of reducing nitrogen oxides on the same bed. That is precisely why a diesel needs separate devices for the two duties while a petrol engine does not.
