摘要： A temperature control system comprises a temperature determination module, a temperature correction module, a temperature control module, and an updating module. The temperature determination module determines a desired outlet temperature for an oxidation catalyst (OC) that is located upstream of a particulate filter (PF) in an exhaust system. The temperature correction module determines a temperature correction from a plurality of temperature corrections. The temperature control module controls an outlet temperature of the OC based on the desired outlet temperature and the temperature correction. The updating module selectively updates at least one of the plurality of temperature corrections when an engine speed and an engine load are within respective predetermined ranges.

摘要： A method controls an exhaust gas temperature from a vehicle engine during regeneration of particulate filter (PF) in a vehicle having an oxidation catalyst (OC) and a selective catalytic reduction catalyst (SCR). The method ensures that a final OC temperature does not exceed a maximum of the target OC outlet temperature and a calibrated maximum OC outlet temperature. An apparatus for controlling a temperature of the exhaust gas includes sensors for measuring a temperature within the exhaust system and a controller having an algorithm, an OC temperature lookup table, and a PF temperature lookup table. The algorithm calculates a target OC outlet temperature using the lookup tables and a delayed error value that compensates for a thermal mass of the SCR. Actual OC outlet temperature is limited during regeneration of the PF to the lesser of the target OC outlet temperature and a calibrated maximum OC outlet temperature.

摘要： A system comprises an injection control module and a fuel film module. The injection control module controls a flow rate of fuel injected into an exhaust system to adjust a temperature of exhaust gas. The fuel film module determines an accumulation rate of fuel on a surface of the exhaust system based on the flow rate of the fuel. The fuel film module determines a release rate of fuel from the surface of the exhaust system based on a flow rate of the exhaust gas. The injection control module adjusts the flow rate of the fuel based on the accumulation rate and the release rate.

摘要： A control module for a vehicle includes a correction module that generates a correction signal based on a regeneration state of an exhaust system of the vehicle and based on a received environmental signal. The environmental signal includes at least one of an altitude value, an ambient temperature, and an air flow value. The air flow value corresponds to air flow across an external area of the exhaust system. A first post injection module generates a first post injection signal. A second post injection module adjusts the first post injection signal based on the correction signal to generate a second post injection signal.
