This research comparatively investigates Diesel and dual-fuel engines. Commercial engine catalogs were used to compile data for the study. The study aims to gain an understanding of the merit of engine types to a broader extend. In these comparison processes, product performance, fuel consumption based on operating performance, NOx emission, air mass and temperature from the exhaust, Energy Efficiency Design Index EEDI, market prices of the engines, and the costs of the fuels they use are all evaluated. The EEDI is calculated using current BIMCO data. To ensure compliance with the 2021 and subsequent regulations, the calculation is carried out on a 161-meter, 1200 TEU container ship. According to the study, the diesel engine appears to be more affordable, taking up less space in the engine room and requiring less auxiliary machinery and equipment. However, when fuel consumption and current prices are compared, the dual-fuel engine can save around $175 per ton of fuel compared to the Diesel engine. Furthermore, when their environmental impact is compared, it has been determined that the diesel engine causes up to around five times more NOx than the dual-fuel engine.
