Abstract
Chemical kinetic mechanism of compression ignition with PRF and NTF (toluene /n-heptane) fuels is investigated according to crank angle resolved in-cylinder sampling experiments. CA resolved profiles of two-stage fuel consumption corresponding with heat releases have been obtained. In PRF, fuel consumption decreases with increasing iso-octane content, and HCHO yield decreases in accordance with the decreasing fuel consumption. On the other hand, the decrease of fuel consumption with increasing toluene content in NTF is weaker, whereas faster decrease of HCHO yield was observed. A simplified reaction model is constructed so as to reproduce observed fuel consumption and intermediate production.
