High-efficiency continuous diesel NOub>xub> reduction method is proposed.
Characteristics of diesel NOub>xub> adsorption and desorption on adsorbent is provided.
Efficiency of NOub>xub> reduction with nonthermal plasma is evaluated.
Efficiency of NOub>xub> reduction with exhaust gas component recirculation is evaluated.
High NOub>xub> removal efficiency equal to only 1.0% penalty of engine power is achieved.
