摘要： A maintenance method for periodically maintaining the operating condition of an exhaust gas recirculation valve for controlling recirculation of internal combustion engine exhaust gas from an exhaust gas path to an engine intake air path in which the valve is periodically driven to a maximum open position and then back to an initial position, such as a closed position when engine operating conditions are such that there is no driveability or emissions penalty associated with such valve maintenance and when sufficient battery drive voltage is available to drive the valve as required for maintenance thereof.

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 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.
