Humphree Exhaust Fin System Humphree Exhaust Fin combines exhaust outlet and a course keeping fin that offers excelent control of exhaust gas back pressure. The base ventilated fin combined with an interceptor makes it possible to create an optimised wake for the exhaust gases to reach the design exhaust gas back pressure for the specific engine. The deep wake enhances the transport of exhaust gases and offers excellent damping of exhaust gas noise resulting in improved comfort aboard. The position of the course keeping fin, in front of the exhaust outlet, eliminates the risk for exhaust gas ventilation of the fin. The compact design makes it possible to retrofit Humphree Exhaust Fin to existing Humphree Exhaust Fin offers: Optimum exhaust gas back Reduced noise Improved transport of exhaust Improved course keeping Minimised risk for ventilation Better control of exhaust gases Increased passenger comfort Computational Fluid Dynamics calculation of the Humphree Exhaust Fin System.
