    摘要: A control system for a vehicle includes a mode determination module that selects one of a first post-injection mode and a second post-injection mode based on a regeneration enable signal and a particulate filter temperature signal. An adjustment module selects one of N ramp rate tables based on the selected one of the first post-injection mode and the second post-injection mode. N is an integer greater than 1. The adjustment module generates a post-injected fuel signal based on the selected one of the N ramp rate tables, an ambient temperature signal and the particulate filter temperature signal. The adjustment module outputs the post-injected fuel signal to a fuel injection system.
