    초록 The excellent performance of SCR(selective catalytic reduction system) using urea as a reductant for
    reducing NOx from diesel engines is verified at numerous factories and industrial engines. The current SCR technology
    is evaluated as the unique catalytic technology which reduces NOx corresponding to the emission regulation in the
    future. Several research on application of the SCR technology in automative diesel engine and on making common use
    were conducted. However the automative diesel engine is strongly influenced by transient driving than by steady state
    driving owing to factors such as drive habit, road condition and traffic status. Therefore the system control strategy is
    required considering the transient state of engines. The research was conducted to investigate the reduction performance
    of NOx as well as investigation of NH3 slip characteristic with various control strategy under transient engine operation
    condition. In terms of base control strategy the sensor base was compared to the map base and an additional control
    algorithm were applied. The setting parameter was changed according to each algorithm in this research.
