ABSTRACT:
A process and system for the regeneration of at least a pair of side-by-side particulate filter traps for purifying the exhaust gas of an internal combustion engine, particularly a motor vehicle diesel engine, by oxidation of particulates collected in the traps, combustion of the particulates being carried out during engine operation by fuel burners respectively associated with the traps, in which a flame jet at high velocity flow is directed from one of the burners for a short duration transversely to the inflow direction of the exhaust gas to be purified directly into an associated trap without mixing with the exhaust gas flow, such that the exhaust gas in the vicinity of the one burner is diverted by the one flame jet to flow into and through the other trap while the one flame jet initiates combustion of the particulates collected in its associated trap.
