摘要： 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.

摘要： A knock diagnostic module having a knock module that increments a sample count when a cylinder firing signal corresponding to a first cylinder is received and selectively increments a knock count based on a knock detection signal that corresponds to the cylinder firing signal of the first cylinder A knock analysis module analyzes the knock count of the first cylinder when the sample count of the first cylinder reaches a predetermined value and selectively generates an excessive knock signal when the knock count exceeds a predetermined threshold. A remedial action module selectively performs a remedial action based on the excessive knock signal.

摘要： A control system is provided and includes a catalyst module that generates a multi-mode enable signal based on a catalyst light off enable signal. A transition control module controls transitions between a single pulse mode and multi-pulse mode based on the multi-mode enable signal. The transition control module receives a first torque signal and generates a second torque signal based on the first torque signal. The engine torque control module generates an air per cylinder signal, a throttle area signal, and a spark timing signal based on the second torque signal. The single pulse mode is associated with a single fuel injection pulse per combustion cycle. The multi-pulse mode is associated with multiple fuel injection pulses per combustion cycle.
