If the vehicle is not currently operating in the low diesel emission fluid inducement protocol, and the diesel emission fluid is at least partially frozen, then a temporary minimum diesel emission fluid mass may be defined to prevent entry of the vehicle into the low diesel emission fluid inducement protocol.

摘要： A diagnostic system for an engine includes an error detection module and a diagnostic module. The error detection module selectively detects a fuel control error based on a change in a fuel correction value used to determine a quantity of fuel supplied directly to an exhaust system. The diagnostic module identifies a cause of the fuel control error based on a period since a last refueling event. The diagnostic module identifies the cause as one of variation in an actual heating value of the fuel and faulty operation of a fuel injection system that supplies the fuel. The diagnostic module further identifies the cause based on a first amount of the fuel contained in a fuel tank at a start of the last refueling event and a second amount of the fuel added to the fuel tank during the last refueling event. A control system and method are also provided.

摘要： A vehicle includes a fuel tank, an internal combustion engine, an oxidation catalyst, a regenerable particulate filter in fluid communication with an outlet side of the oxidation catalyst, and a host machine. The host machine calculates an actual hydrocarbon level in the exhaust stream downstream of the particulate filter as a function of an actual energy input value and an actual output value of the oxidation catalyst, and subsequently executes a control action using the actual hydrocarbon level. A method for use aboard the vehicle includes using the host machine to calculate an actual hydrocarbon level in the exhaust stream downstream of the particulate filter, including solving a function of an actual energy input value and an actual energy output value of the oxidation catalyst, and executing a control action aboard the vehicle via the host machine using the actual hydrocarbon level.

摘要： A regeneration control system for a vehicle includes a regeneration control module and a regeneration interrupt module. The regeneration control module selectively provides fuel to an oxidation catalyst for a regeneration event of a particulate filter that occurs during a predetermined melting period for frozen dosing agent. The regeneration interrupt module selectively interrupts the regeneration event and disables the provision of fuel to the oxidation catalyst before the regeneration event is complete when a temperature of a dosing agent injector that is located between the oxidation catalyst and the particulate filter is greater than a predetermined temperature.

摘要： An exhaust treatment system for exhaust gas produced by an engine includes a condition control module, a load determination module, and an age determination module. The condition control module decreases a load on a selective catalytic reduction (SCR) catalyst below a predetermined load threshold and increases exhaust gas temperature (EGT) to a predetermined temperature. The load determination module increases injection of a dosing agent into the exhaust gas and determines a load on the SCR catalyst when dosing agent is detected downstream from the SCR catalyst. The age determination module determines an age of the SCR catalyst based the determined load and predetermined loads for first and second SCR catalysts, respectively.

摘要： An engine system includes an aging factor generation module, a temperature comparison module, and a mode control module. The aging factor generation module generates an aging factor that indicates deterioration of a catalyst in a selective catalytic reduction (SCR) system. The temperature comparison module compares inlet and outlet temperatures of the SCR system to predetermined effective inlet and outlet temperatures of the SCR system, respectively, wherein the predetermined effective inlet and outlet temperatures are based on the aging factor. The mode control module controls at least one of a throttle and a plurality of fuel injectors based on a first predetermined air/fuel (A/F) ratio when the inlet and outlet temperatures of the SCR system are greater than the predetermined effective inlet and outlet temperatures of the SCR system, respectively.
