Prevention Instead of Repair!

Neue Reinigungstechnologien sorgen für die Werterhaltung des Kraftstoffsystems und verbesserte Fahrleistungen. Dazu gehört zum Beispiel, die Injektor-Düsen, die inzwischen nur noch den Durchmesser eines Haares haben, von Verkokungen und Ablagerungen freizuhalten. Die TUNAP Lösungen zur Kraftstoffsystem-Reinigung helfen dabei, betroffene Fahrzeuge in kurzer Zeit und mit geringen Materialkosten wieder einsatzbereit zu machen.

Chart illustrates the problem of increasing CO2 emissions after driven kilometers


Diesel, Super petrol, E10, B7: The choice at the petrol station is increasingly complex. Internationally varying legislations, highly developed motor technology and increasingly stricter emission standards are the reasons for a reduced harmony between engine and fuel.

The chemical processes in fuel systems generate contamination, deposits, coking and varnish.


  • Increased emission
  • Increased fuel consumption
  • Susceptibility to faults
  • Expensive repairs

New technological cleaning concepts aim less at a Formula 1 feeling but rather at preservation of the fuel system. This includes e.g. keeping the fuel injection nozzle holes, which nowadays have the same diameter as a human hair, free of coking and deposits.

TUNAP fuel and manifold system cleaning products help get you back on the road quickly at economic costs for chemicals and tools and have great potential to generate external economies.


  • Less emission
  • Lower fuel consumption
  • Fewer repairs
  • Major cost savings
  • Increased customer satisfaction
