Abstract
According to one embodiment, an apparatus for controlling regeneration events on multiple diesel particulate filters (DPFs) of an exhaust after-treatment system includes a regeneration event synchronization module and regeneration event termination module. The regeneration event synchronization module is configured to simultaneously initiate a regeneration event on a first DPF and a regeneration event on a second DPF in response to a regeneration event request being triggered for one of the first and second DPFs. The regeneration event termination module is configured to terminate the regeneration event on the first DPF and the regeneration event on the second DPF. Under normal operating conditions, the termination of the regeneration event on the first DPF is performed independently of the termination of the regeneration event on the second DPF.
