Exhaust gas recirculation control systems and methods
Abstract:
A fuel control system of a vehicle includes an injection control module and a command module. The injection control module determines a first target amount of fuel for a combustion event of an engine. A command module selectively command the injection control module to provide two fuel injections when a torque request decreases. In response to the command, the injection control module: determines second and third target amounts of fuel based on the first target amount; provides a first fuel injection during the combustion event based on the second target amount; and provides a second fuel injection during a compression stroke of the combustion event based on the third target amount.
