    摘要： A diagnostic cold start emissions control system for an internal combustion engine includes a control module having a calculated engine-out energy module, an engine-out energy residual module, and a diagnostic system evaluation module. The calculated engine-out energy module is in communication with the engine-out energy residual module and is configured to determine an operating engine-out energy flow based on an operating engine torque. The engine-out energy residual module is in communication with the diagnostic system evaluation module and is configured to determine an engine-out energy residual based on the determined engine-out energy flow and an expected engine-out energy flow. The diagnostic system evaluation module is configured to determine whether the determined engine-out energy residual meets a predetermined value indicative of proper cold start emissions control.

    摘要： A diagnostic system for an engine includes a stage transition module and a control module. The stage transition module generates a command signal based on a fuel control signal. The command signal commands a fuel system of the engine to intrusively transition between rich and lean states during a diagnostic test that includes first, second, and third stages. The first, second, and third stages are defined based on transitions between the rich and lean states. The control module during the second and third stages detects: an error with a first oxygen sensor based on a comparison between the command signal and a first oxygen signal from the first oxygen sensor; an error with a second oxygen sensor based on a second oxygen signal from the second oxygen sensor; and an error with a catalytic converter based on the first and second oxygen signals and a manifold absolute pressure signal.

    摘要： A control system for an engine having a catalytic converter includes an energy calculation module that calculates a calculated mass air flow (MAF) of intake air of the engine based on a requested torque and a requested spark timing that correspond to a desired thermal energy of exhaust of the engine, and that determines an expected thermal energy of the exhaust based on the calculated MAF, and an energy residual module that determines a thermal energy residual of the exhaust based on the expected thermal energy and an estimated thermal energy of the exhaust, wherein the estimated thermal energy is based on a measured MAF of the intake air. The control system includes an energy evaluation module that determines a diagnostic result that indicates whether the catalytic converter is operating within a target temperature range based on the thermal energy residual. Related control methods are also provided.

    摘要： An engine control module includes a spark control module, an engine speed module, a residual determination module, and a metric determination module. The spark control module actuates spark plugs based on a commanded spark timing. The engine speed module determines a desired engine speed based on an engine temperature and a period of time an engine is in operation after a cold start. The residual determination module determines a desired spark timing based on the desired engine speed, and determines a residual spark timing based on a difference between the commanded spark timing and the desired spark timing. The metric determination module detects a spark timing fault based on the residual spark timing and a predetermined spark timing range.
