This paper describes NO_X reduction for a diesel engine using exhaust gas component recirculation (EGCR). EGCR is the aftertreatment technology for NO_X reduction by intake of NO_X extracted from exhaust gas to diesel engine. In this experiment, NO_X aftertreatment system equipped with heat exchanger and absorbent by using EGCR in the small diesel engine generator is investigated. EGCR system consists of absorption process and desorption process. These processes are conducted for 60 min each a cycle, and 5 cycles of experiments are investigated. The NO_X reduction efficiency of 36.9% is in the one cycle obtained. The numerical simulation of NO_X reduction using EGCR for the marine engine practically used in ships is also carried out.
