Abstract
It is well known that most marine vessels are equipped with diesel engines. However, their efficiency is not as high as expected. Fuel prices are rising; therefore, operational costs of the vessels bring a high economic burden. Moreover, International Maritime Organization and the states put regulations and laws into action to avoid the environmental problems related to marine vessels. Design of more efficient marine engine systems is an approach to decrease emissions as well as fuel consumption. However, it is better to acquire the inefficiencies within the system. So, exergy analysis shows the wasted maximum work potential of a system by introducing the exergy destruction based on entropy generation, where entropy is a tool in thermodynamics to identify inefficiencies. In this study, an eight-cylinder two-stroke turbocharged diesel engine of a crude oil carrier is investigated by applying exergy analysis. The results reveal the potential recovery of exergy to produce more power and the improvement potential of the engine efficiency.
