| Popis: | The Homogenous Charge Compression Ignition (HCCI) combustion in an natural gas (Methane) and Heptane fueled engine using detailed chemical kinetics is investigated in this research. Sensitivity analysis of O, H, CH and OH species have been performed for the two sample fuels. The effect of heat transfer of start of combustion (SOC) and temperature gradient have been investigated. The SOC shifts to the higher crank angles as the heat transfer is considered because of the heat loss to the cylinder body and later combustion is happening inside the cylinder. |
