Disadvantages of the EP6CDTX engine

  • This turbine unit is extremely demanding on the quality of fuel and oil used;
  • Many problems are associated with accelerated carbon formation, especially on valves;
  • Almost always, a progressive oil burner follows engine coking;
  • A thin timing chain is often stretched already to a run of 80 – 100 thousand kilometers;
  • The electromagnetic clutch in the pump drive can fail even at 50,000 km;
  • The performance of the phase control system depends on the condition of the oil channels;
  • The cause of the failure of the high-pressure fuel pump and other components of the fuel system in bad gasoline.
