Exhaust gas management systems for underwater heat engines

In hydrocarbon fuelled air-independent power system research, whether an internal/external combustion heat engine, or fuel cell, an exhaust gas management system is required. In previous research many techniques have been proposed for the control and/or removal of the combustion generated exhaust products, notably heat exchangers and carbon dioxide separation techniques. However, there has been little research on the merits of one system verses another for a particular vehicle application and engine. To address the systems and their applicability to a particular power system and vehicle, the paper assesses and evaluates exhaust gas management systems for a Stirling engine driven diver propulsion vehicle.
