Abstract

The effect of SI engine fuels which contain ethanol on lubricant degradation has hardly been investigated today. The research project FVV 930 by Clausthal Technical University, Kassel University and IFOS Kaiserslautern indicate that the engine life is impaired by operation with E85. For the timing chain as an indicator of tribological processes in this investigation, the rate of wear increases by 20 %.
