METHOD TO CONVERT EXHAUST GASES OF INTERNAL COMBUSTION ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: according to proposed method, flow of exhaust gases is divided into two parts, one of which is passed through external reaction chamber and the other, through internal chamber. Final oxidation of exhaust gases in external and internal reaction chambers is carried out under different conditions: in external reaction chamber exhaust gases are heated by higher temperature of non-heat-insulated walls of internal reaction chamber. Moreover, in external reaction chamber conditions are created additionally for neutralizing toxic combustion products by mixing them with atmospheric air, and time of stay of exhaust gases in zone of final oxidation is increased owing to installation of partitions. In external reaction chamber, duration of stay of exhaust gases in zone of final oxidation is increased by means of partitions made of platinum. High temperature of exhaust gases in internal reaction chamber is provided by flow of exhaust gases and their final oxidation in external reaction chamber. Density of exhaust gases getting out of reaction chamber is decreased by injection of water vapors into external reaction chamber at its outlet.

EFFECT: improved efficiency of conversion of exhaust gases.
