Abstract:
Exhaust generated from an internal combustion engine includes particulates and gas-phase volatile hydrocarbon condensables. The exhaust is cooled in an exhaust gas cooler from a first temperature to a second temperature such that a first portion of the gas-phase volatile hydrocarbon condensables in the exhaust condense to the liquid phase and a second portion of the gas-phase volatile hydrocarbon condensables in the exhaust condense on black carbon particles to form semivolatile brown carbon particulates. Some or all of the liquid-phase volatile hydrocarbon condensables and the semivolatile brown carbon particulates are trapped in a gasoline particulate filter or a catalyzed gasoline particulate filter located downstream of the exhaust gas cooler.

Claim (Index 1):
A system for reducing emissions in exhaust generated by an engine, said exhaust comprising particulates and volatile hydrocarbon condensables, the system comprising:\n a heat exchanger having an inlet that receives said exhaust at a first temperature and an outlet that outputs said exhaust at a second temperature, the second temperature lower than the first temperature, wherein said heat exchanger causes at least some of said volatile hydrocarbon condensables to condense; and a gasoline particulate filter (GPF) having an inlet in fluid communication with the outlet of said heat exchanger to receive said exhaust at said second temperature, said GPF having an outlet to output said exhaust, said GPF trapping at least some liquid-phase volatile hydrocarbon condensables and at least some of said particulates, thereby reducing said emissions from said engine.
