Briefly talk about exon value in marine

engineering Exon value is a term used in marine engineering to describe a measure of the value of fuel efficiency or performance of a particular engine. It is calculated based on a variety of factors such as exhaust gas temperature, engine displacement, number of cylinders, and other specifications. By quantifying the efficiency of an engine, engineers can make more informed decisions about which engines are optimal for certain applications. Additionally, exon values can help inform decisions regarding the cost effectiveness of certain engines and the economic impacts of investing in technology such as next-generation engine designs.
