INTERNAL COMBUSTION ENGINE EXHAUST GAS CATALYTIC CONVERTER Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed exhaust gas catalytic converter of internal combustion engine contains housing with inlet and outlet branch pipes, several reactors with catalysts arranged in parallel with gas flow and exhaust gas distributor made in form of disk enclosed in case in front part of which in direction of gas flow and on outer surface of distributor diametric grooves are made with balls fitted in space of groove, so distributor is installed for movement relative to case with possibility of rotation under action of exhaust gas pressure. Slot is made in lower part of housing under distributor in which ball lock is fitted, and on outer surface of distributor, parallel of diametric groove, cavities are made for lock ball. Idle run sector is made on front end face wall of distributor whose angle is equal to angle of sector of catalytic reactor, and regenerative sector is placed in its space formed by two inner partitions and rear end face wall equal to two idle run sectors, gas flow rate adjusting gate installed for rotation relative to distributor under action of exhaust gas pressure, spring installed on axle and rigidly connected with gate in zone of no direct action of exhaust gases. Diametric vanes are installed on front end face wall of distributor at angle in direction opposite to direction of rotation of gas flow rate adjusting gate under action of exhaust gas pressure.

EFFECT: improved efficiency of exhaust gas cleaning.
