Selective catalytic reduction (SCR) is commonly employed to reduce NOx emissions and meet Tier III regulations for marine diesel engines. However, challenges arise when applying SCR to two-stroke diesel engines because the catalyst may not function effectively at lower exhaust gas temperatures. To address this issue, exhaust gas recirculation (EGR) has been introduced in two-stroke diesel engines, such as the T/S Baek-kyung, a Pukyong National University training ship. There are ecoEGR to improve fuel consumption. The T/S Baek-kyung is equipped with a controllable pitch propeller and uses a combinator mode for normal sailing, which differs from the operating conditions in the NOx technical files; therefore, data from actual operations are rare. Sailing data under various conditions (loads and EGR rates) were obtained and analyzed. A comparison of the Tier II and ecoEGR modes showed no significant difference in engine performance; however, there was a reduction in NOx and particulate matter with an increase in CO₂. There was a significant difference in the performance at approximately 50% load owing to the influence of the combinator mode.
