Abstract

See full text

A controller for controlling regeneration in an aftertreatment system comprising a first leg and a second leg is configured to: determine whether regeneration is permitted by the engine based on engine operating parameters; in response to regeneration being permitted, determine whether regeneration is required in at least one of the first leg or the second leg based on operating parameters of the first leg and the second leg, and whether regeneration is inhibited in either the first leg or the second leg; and in response to determining that (i) regeneration is required in at least one of the first or second leg, and (ii) regeneration is not inhibited in either the first or the second leg, cause insertion of hydrocarbons into the engine to thereby increase the temperature of the exhaust gas to a target temperature and cause regeneration in each of the first and second leg.
