Embodiment Construction
[0089] figure 1 Shown is an exhaust gas recirculation system 1 installed between an exhaust gas outlet 3 and an air inlet 4 of an internal combustion engine 2 of a vessel. The exhaust gas recirculation system 1 is connected to the exhaust gas outlet 3 by means for connecting the exhaust gas recirculation system 1 to the exhaust gas outlet 3 . The device can be, for example, a welded or flanged pipe. The exhaust gas recirculation system 1 is connected to the air inlet 4 by means for connecting the exhaust gas recirculation system 1 to the air inlet 4 . The device can also be welded or flanged pipe. The exhaust gas recirculation system 1 includes an exhaust gas inlet valve 5 , an exhaust gas purifier 6 , a control unit 7 , a gas sensor 8 , a cooler 9 , a water separator 10 and a booster device 11 . An exhaust gas pre-scrubber 14 and an exhaust gas recirculation valve 12 are optionally provided. Exhaust gas is introduced from an exhaust gas outlet 3 of an internal combustion ...

The invention relates to an internal combustion engine, an exhaust gas recirculating system, a method for monitoring the exhaust gas recirculating system, and a method for retrofitting the exhaust gas recirculating system. The exhaust gas recirculation system (1) for the internal combustion engine (2) has an exhaust gas outlet (3) and an air inlet (4). The internal combustion engine is preferably a ship engine. The exhaust gas recirculating system comprises a device for connecting the exhaust gas recirculating system to the exhaust gas outlet, and a device for connecting the exhaust gas recirculating system to the air inlet, wherein the exhaust gas can be guided, in the exhaust gas flow direction, from the device for connecting the exhaust gas recirculating system to the exhaust gas outlet (3) to the device for connecting the exhaust gas recirculating system to the air inlet (4). The exhaust gas recirculating system includes an exhaust gas inlet valve (5) for controlling the intake of exhaust gas into the exhaust gas recirculating system, an exhaust gas purifier (6), and a control unit (7) for controlling the exhaust gas flow through the exhaust gas recirculating system (1). A device for detecting a stop index is provided, by means of which a control signal can be sent to the control unit.
Description
technical field [0001] The invention relates to an exhaust gas recirculation system of an internal combustion engine, an internal combustion engine, a method for monitoring the exhaust gas recirculation process of the internal combustion engine, a method for refitting the exhaust gas recirculation system, and a kit for refitting the internal combustion engine. Background technique [0002] Due to restriction NO x Tougher regulations on values, such as exhaust gas recirculation systems, are more widely used, especially in the field of large engines in nautical engineering. The exhaust gas recirculation system recirculates part of the exhaust gas back to the air intake of the engine, wherein the exhaust gas is usually cleaned in the exhaust gas recirculation system due to the composition of the fuel used and the particulate matter produced during combustion. Purging is carried out with the aid of an exhaust gas cleaner. [0003] In previous systems, it had the disadvantage o...
