Abstract: In an exhaust gas purifying system (1) that purifies NOx for the exhaust gas from an internal combustion engine (E) through sulfur purging control by a NOx occlusion reduction type catalyst (41), sulfur purging is judged to have started when the oxygen concentration (Co) detected by an oxygen concentration detection means (54) disposed downstream of the NOx occlusion reduction type catalyst (41) drops from a first predetermined oxygen concentration indicating that the NOx discharge condition to a second predetermined oxygen concentration indicating that NOx discharge has ended and that SOx discharge has started. Accordingly, during sulfur purging control by the NOx occlusion reduction type catalyst (41), consideration is given to the discharge of NOx without sulfur purging at the start of sulfur purging control; furthermore, this timing is judged by monitoring the concentration of oxygen downstream of the NOx occlusion reduction type catalyst (41), thus optimizing sulfur purging control.

Abstract: A new type of diverging nozzle is used to convert the energy of wind and subsurface ocean current into electrical energy. The nozzle is of either spherical or teardrop shape with a small hole in the surface facing the fluid stream. The fluid is made to exit through the surface where the widest diameter of the shape is. The fluid is drawn out by the Bernouilli Effect into the passing fluid stream. As the fluid is accelerated through the small hole the fluid in a tube whose first entrance is near the small hole has its pressure reduced. The tube's second entrance is an inlet tube to a Bourdon Tube. The flexing of the Bourdon tube is made to operate an electric generator through certain gearing. As long as there is a pressure difference between the fluid within the tube and the atmosphere then pressure within the Bourdon Tube can be alternated by valves so electric power output is maintained. Offshore, no moving parts are employed in the invention.
