Abstract
The exhaust gas of a diesel engine is washed and then a centrifugal separator divides the gas into an O.sub.2 enriched component and a CO.sub.2 enriched component. Additional oxygen is added to the former component and it is used by the engine for combustion purposes. Water in a pressurized tank is employed to remove CO.sub.2 from the CO.sub.2 enriched component. Thereafter the latter is fed back to the gas stream going to the engine for combustion.
Claims8
An internal combustion engine installation wherein said engine has an intake for receiving an oxidizible fuel and a gas intake for receiving an oxidizing fuel gas and an exhaust at which the products of combustion, including carbon dioxide gas, are discharged along with some unburned oxidizing fuel gas, said installation including
- closed circuit conduit means interconnecting said exhaust and said gas intake for receiving said gases at said exhaust and for feeding back a portion of said received gases to said gas intake, said conduit means including centrifugal separator means for dividing said received gases into two partial streams, one of which has a higher concentration of O.sub.2 than did the received gases and the other of which has a higher concentration of CO.sub.2 than did the received gases, said conduit means delivering said one partial stream to said gas intake.
