ABSTRACT:
An EGR cooling system is provided. The EGR cooling system comprising a plurality of EGR coolers configured to cool the EGR to a plurality of successively lower temperatures, where at least one of the plurality of EGR coolers includes a finned EGR cooler that comprises a plurality of channels for dissipating heat in the EGR, the plurality of channels increasing heat transfer surface area while having sufficient fin spacing to avoid clogging. The EGR cooling system may further comprise a catalyst configured to remove particle matters and/or hydrocarbons from the EGR, the catalyst positioned upstream of at least one of the plurality of EGR coolers.
