correction method would be speculative. Nevertheless, when only
considering the data in the temperature range from 20 to 80 C, the
CO graphs in Fig. 8 show a consistently decreasing trend. The CO
emissions are reduced by about 21% over this temperature range.
To avoid influence of combustion chamber pressure fluctuations,
the rotational speed was controlled more precisely in the
subsequent experiments. Therefore, a strong effect of the CCP on
the presented results for vegetable oil can be ruled out
