Claim Text:
1. A regeneration system comprising: a bypass valve; a first electronic circuit configured to generate a first comparison signal based on at least one of (i) a comparison between a first temperature of an adsorber and an adsorber release temperature and (ii) a comparison between a second temperature of an engine and a predetermined temperature; a second electronic circuit configured to (i) determine whether the engine is operating in a low particulate matter output mode by comparing an amount of particulate matter output of the engine to a predetermined amount and (ii) generate a second comparison signal indicating whether the engine is operating in the low particulate matter output mode, wherein the engine is operating in the low particulate matter output mode if the amount of particulate matter output is less than the predetermined amount; a third electronic circuit configured to select a mode and to generate a mode signal based on the first comparison signal and the second comparison signal; and a fourth electronic circuit configured to, based on the mode signal, adjust a position of the bypass valve to bypass at least one of a particulate matter (PM) filter and the adsorber, wherein the fourth electronic circuit is configured to open the bypass valve to bypass the adsorber in response to the first temperature of the adsorber being greater than the adsorber release temperature, the second temperature of the engine being greater than the predetermined temperature, and the amount of particulate matter output of the engine being less than the predetermined amount; and close the bypass valve to direct exhaust gas through the adsorber in response to the first temperature of the adsorber being less than or equal to the adsorber release temperature, the second temperature of the engine being less than or equal to the predetermined temperature, and the amount particulate matter output of the engine being greater than or equal to the predetermined amount.
