초록
Environmental regulations are being reinforced for the solution of environmental pollution, that are globalissues. Exhaust gas regulations of off-road engines also demand stepwise reduction emission from beginningof Tier 4 interim(2013). Characteristically, Tier 4 regulation apply the NRTC mode which is a transient cycle. And technical studies using NRTC mode are uncommon. In this study, for satisfy the Tier 4 final regulationon the NRTC mode, experimental study was conducted using a 3.4 L off-road engine. Fuel injection timing andinjector hole number are chosen as parameters for investigation of combustion and exhaust gas characteristicson off-road diesel engine.
