GDI carbon buildup

  • A relatively new challenge facing technicians is in dealing with the drivability effects of carbon in the intake track and combustion chamber.
  • Driven by emission laws, more vehicles are being equipped with gasoline direct injection systems (GDI); however, a common complaint about these vehicles has been the buildup of carbon deposits inside the cylinder head.
  • Google “gasoline direct injection problems,” and it won’t take you long to see that many early adopters of this technology faced issues with severe carbon buildup occurring on the stem and throat of the intake valve.
