Abstract
A regeneration system for a filter that filters exhaust gas of an engine includes a soot loading determination module that determines soot accumulation in the filter. A regeneration control module receives the determined soot accumulation from the soot loading determination module, compares the soot accumulation to a first soot accumulation threshold, and selectively increases oxidation levels in the exhaust gas in response to the comparison between the soot accumulation and the first soot accumulation threshold to initiate regeneration in the filter.
