The investigation of knocking, pre-ignition and/or self-ignition behaviour of the overall system (engine, fuel and lubricating oil) is a vital step for optimizing future gasoline engines and their consumables. To this end, new adjusted test methods need to be developed. The creation of derived characteristic numbers for fuel and oil, if possible, would be necessary to determine the irregular behaviour in a reproduceable and realistic manner.
The knocking and pre-ignition behaviour of selected alternative fuels were investigated at the Institute for Powertrains and Automotive Technology of Vienna University of Technology, while the research focus of the Institute for Internal Combustion Engines and Thermodynamics of Graz University of Technology was on the influence of lubricating oil on pre-ignition.
