Abstract
A coordinated torque control system includes a catalyst module that generates a multi-mode enable signal based on a catalyst light off enable signal. A torque reserve module generates a torque reserve signal based on the multi-mode enable signal, an engine speed signal and an air per cylinder signal. The torque reserve module operates in a multi-pulse mode that is associated with injecting N pulses of fuel into a combustion chamber during a combustion cycle of the engine based on the multi-mode enable signal. N is an integer greater than or equal to 2.
