System and method for particulate matter filter regeneration using a catalytic converter as a combustor |
摘要 |
A control system for an engine includes an exhaust module and a combustion module. The exhaust module supplies a first MAF to exhaust produced by the engine upstream of a catalytic converter during regeneration of a PM filter located downstream of the catalytic converter. The combustion module, during the regeneration, supplies a first amount of fuel to a cylinder during an intake stroke based on the first MAF and a second MAF to the cylinder during the intake stroke. The combustion module, during the regeneration, further supplies a second amount of fuel to the cylinder during a subsequent intake stroke based on a first A/F ratio of the cylinder and an oxygen content of the exhaust downstream of the catalytic converter. A method for controlling an engine during regeneration of the PM filter is also provided.
