CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

An exhaust passage 12 of an internal combustion engine 10 is provided with an upstream side three-way catalyst 16 capable of purifying exhaust gas and a particulate filter (PM filter) 18 for trapping particulate matter PM contained in exhaust gas. Catalyst warm-up control is exercised for the purpose of warming up mainly the upstream side three-way catalyst 16 at cold start. Filter regeneration control for removing the particulate matter PM accumulating on the particulate filter 18 from the filter 18 is exercised at the cold start after the catalyst warm-up control is exercised.
