The CO.sub.2 separation system performs, when the internal combustion engine is operating and the vehicle is travelling, a first mode wherein exhaust gas generated by the internal combustion engine is introduced to a CO.sub.2 supply side of a first CO.sub.2 separation device via a first CO.sub.2 supply side introduction flow path, and air from outside the vehicle is introduced to a CO.sub.2 permeation side of the first CO.sub.2 separation device via a first CO.sub.2 permeation side introduction flow path using travelling wind, whereby CO.sub.2 in the exhaust gas selectively permeates from the CO.sub.2 supply side to the CO.sub.2 permeation side of the first CO.sub.2 separation device through a CO.sub.2 permeable membrane of the first CO.sub.2 separation device using a difference in CO.sub.2 partial pressure between the CO.sub.2 supply side and the CO.sub.2 permeation side of the first CO.sub.2 separation device as a driving force.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel cooperated with exhaust gas recirculation (EGR), and a vessel including the same, in which NO.sub.X generation is reduced, which is the original purpose of EGR, while maintaining existing EGR, SO.sub.X as well as CO.sub.2, which is the representative greenhouse gas, are absorbed and converted into materials that do not affect environments, and the materials are discharged or stored as useful materials, thereby preventing corrosion of an engine and improving combustion efficiency.

A system and method for carbon dioxide capture/storage from exhaust utilizing a carbon dioxide separation membrane which may be prepared in the form of a monolithic structure. The captured carbon dioxide may also be stored in a fluid state as supercritical CO.sub.2. An integrated fuel delivery and carbon dioxide unloading system is also disclosed, to remove carbon dioxide from a vehicle for sequestration or other industrial purposes.

A method for purifying the exhaust gas generated by an internal combustion engine, wherein the exhaust gas generated by the internal combustion engine is conducted through an exhaust gas path in which at least one adsorption element is arranged, to which pollutants contained in the exhaust gas at least partly bind, and in which the at least one adsorption element is regenerated by at least partial desorption of the bound pollutants, and pollutants desorbed from the at least one adsorption element during the desorption process are stored in at least one storage unit.

A high-pressure SCR system with venting and pressure-stabilizing for marine diesel engine, comprising an SCR reactor, a gas intake pipeline, an exhaust pipeline, a bypass pipeline, a pneumatic pipeline, first and second auxiliary pipelines When denitrification treatment is needed, the exhaust gas can enter from a flue gas inlet, sequentially pass through the gas intake pipeline, the SCR reactor, and the exhaust pipeline, and be discharged from a flue gas outlet. When denitrification treatment is not needed, the exhaust gas can enter the bypass pipeline from the flue gas inlet and be discharged from the flue gas outlet, the exhaust gas in the SCR reactor and exhaust pipeline being pushed by compressed air entering from the first and second auxiliary pipelines to be discharged from the flue gas outlet. Also provided is a ship.

An exhaust system for an internal combustion engine is connected to an outlet of the internal combustion engine and has a particulate filter. A differential pressure line for ascertaining the particulate filter load connects a section of the exhaust passage upstream from the particulate filter and a section of the exhaust passage downstream from the particulate filter to a differential pressure sensor. At an end of the differential pressure line facing the exhaust passage, a reservoir which serves to collect condensate protrudes into the exhaust passage and can be heated up by the exhaust gas in the exhaust passage. Due to the heating of the reservoir, the liquid that has collected in the reservoir evaporates and can be introduced in gaseous form into the exhaust passage through an opening in the reservoir, so that the risk of droplet formation in the exhaust passage is avoided.

The technology disclosed herein relates to a system for the efficient capture and storage of carbon dioxide from a vehicle's exhaust while in transit. The system includes an apparatus for extracting the carbon dioxide from an exhaust gas and passing it to a compressor or carbon dioxide management system. The system then compresses the carbon dioxide and determines if a tire has capacity for the carbon dioxide. The tire has a carbon dioxide chamber and an external air chamber. If the carbon dioxide air chamber has capacity, the compressor will supply compressed carbon dioxide into the carbon dioxide chamber. Upon arrival at an external storage location, the carbon dioxide stored in the tires are able to be extracted and supplied to the external storage location.

An exhaust gas aftertreatment device 30 of an internal combustion engine 1 includes a catalyst 24 provided in an exhaust passage 4, a first branch passage 31 having one end 35 connected to an exhaust passage downstream of a catalyst, a second branch passage 32 having one end 38 connected to the exhaust passage upstream of the catalyst, a tank 33 to which the other end 36 of the first branch passage and the other end 39 of the second branch passage are connected and capable of storing exhaust, a valve mechanism 34 configured to switch open and closed states of the first branch passage, the second branch passage, and a downstream portion 41 of the exhaust passage downstream of a branch point 37 to which the one end of the first branch passage is connected, and a control unit 100 configured to control the valve mechanism.

Methods and systems are provided for regulating exhaust flow through an exhaust system of an engine. In one example, a method may include directing exhaust from downstream of a catalytic converter to a compressor storage tank in response to an engine air-fuel ratio deviating from stoichiometry. The stored exhaust may be released from the compressor storage tank to recirculate through the catalytic converter to atmosphere after adjusting an air-fuel ratio of the exhaust in the storage tank and when the he catalytic converter is at a target operating temperature.
