    This study investigated the effect of target species changing on the mechanism reduction in DRGEP(Directed Relation Graph Error Propagation) method. To achieve this goal, the automatic mechanism reduction scheme of reaction workbench which includes DRGEP method was introduced and the 0-D combustion analysis of CHEMKIN-PRO was executed to confirm the error rate of ignition delay between the detailed mechanism and reduced mechanisms. To consider various target species, the skeletal mechanism for biodiesel and n-heptane mechanism were merged and the various environments were considered to decide the environment of the mechanism reduction by changing the relative and absolute tolerance associated with the mechanism reduction. As a result, it was confirmed that the target species has a great influence on the reduction of the mechanism, and it was appropriate to consider chemical species, as the target species, associated with exhaust emissions.
