    摘要: An engine control system comprises a torque request module, an immediate torque control module, an actuation module, and an expected torque control module. The torque request module generates an expected torque request and an immediate torque request. The immediate torque control module controls a spark advance of an engine based on the immediate torque request. The actuation module selectively reduces the expected torque request based on the immediate torque request and a spark capacity. The spark capacity is based on a difference between a first engine torque and a second engine torque, determined at a current airflow. The first engine torque is determined at a first spark advance and the second engine torque is determined at a second spark advance that is less than the first spark advance. The expected torque control module that controls a throttle valve area based on the expected torque request.

    摘要: An oxygen storage capacity (OSC) monitoring system for a vehicle having a catalytic converter includes a control module that determines a measured OSC based on an inlet sensor signal (ISS) that is responsive to an oxygen content of exhaust flowing into the catalytic converter. The control module determines a normalization ratio based the measured OSC and determines a PASS/FAIL status of the catalytic converter based on the normalization ratio.
