Abstract
A thermal management system includes a catalytic converter module that determines whether a catalytic converter is active. A selective catalytic reduction (SCR) catalyst module determines whether a SCR catalyst is active. An engine control module adjusts an air and fuel ratio of an engine to operate at a stoichiometric ratio and retards spark of the engine when the catalytic converter is not active. The engine control module at least one of performs post fuel injection and directly injects fuel into an exhaust system of the engine when the catalytic converter is active and the SCR catalyst is not active.
