It is known that EGR is general technology reducing NOx emitted from the internal combustion engine. Many studies concerning NOx reduction have been performed as SCR, EGR and etc. EGR system reduces NOx and increases particulate matter, this phenomenon is said trade-off relationship. In this study, we have performed experimental study that EGR system was applied to construction machine to confirm emission trend by different EGR ratio. This EGR is controled electrically and accepted cooler using water. CPC to measure particle number was used and the sample gas directly was extracted from the tailpipe. We estimated emission on several conditions that have three engine speed, partial load and different EGR ratio. NOx have a trend of decreasement by increasing EGR ratio on same engine speed. But PM and PN have the trend of increasement by increasing EGR ratio on same engine speed.
