Abstract:
The ignition and combustion behaviour is of vital importance for a fuel to be used in diesel engines. For vegetable oils only little information is available concerning the ignition and combustion behaviour. Thus, target of the project was to determine the ignition and combustion behaviour of different vegetable oils in a Fuel-Ignition-Tester. The study was done by using ten different vegetable oils and two mixtures of vegetable oils. The vegetable oils were characterised by using their fatty acid composition. Based on that, the average number of double bonds and the average number of carbon atoms of the fatty acids were calculated. The results were evaluated using a multivariate regression analysis. The analysis showed that the average number of carbon atoms had no significant effect on the ignition delay. Between the average number of double bonds and the ignition delay a linear relationship with a high coefficient of determination was observed. It was recognized, that an increasing number of double bonds leads to a longer ignition delay. The longer the ignition delay the higher the amount of fuel burning in the first, premixed combustion phase. In the subsequent combustion phases the vegetable oils showed no differences.
