摘要： 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.

摘要： Various embodiments may include a method for regenerating a particle filter comprising: increasing a measured exhaust-gas temperature from a normal operation level to above a desorption start temperature defined by initiating release of sulfur compounds accumulated in the particle filter; monitoring a particle mass in the exhaust-gas flow downstream of the particle filter; comparing the particle mass to a predefined threshold value above which the formation of white smoke can be expected; if the threshold value is exceeded, setting the exhaust-gas temperature to a desorption temperature for release of sulfur compounds until the particle mass falls below the threshold; if the particle mass threshold value is not exceeded, setting the exhaust-gas temperature to a regeneration temperature for burning-off of the particle loading of the particle filter for a predetermined time period; and after the time period has elapsed, ending the regeneration by lowering the temperature to the normal operation level.
