摘要： A method of heating a cabin of a motor vehicle that includes an internal combustion engine operatively connected to an exhaust system having a catalyst, and a heating, ventilation, and air conditioning (HVAC) system is provided. The method includes detecting a request to increase temperature inside the cabin, supplying fuel and air to the engine, and motoring the engine to pump the fuel and air into the exhaust system. The method also includes heating the catalyst to combust the fuel and air inside the catalyst such that a stream of post-combustion exhaust gas is generated. The method additionally includes channeling the generated stream of post-combustion exhaust gas to the HVAC system such that a temperature of a coolant circulated through the HVAC system is increased to heat the cabin. A system configured to perform the above method is also disclosed.

摘要： A method of operating a hybrid vehicle when an internal combustion engine is not running includes heating a flow of air flowing through an exhaust gas treatment system of the internal combustion engine that is supplied by an air pump with a heating module and a hydrocarbon injector. The heating module heats an electrically heated catalyst of the exhaust gas treatment system in preparation for starting the internal combustion engine. Additionally, thermal energy is recovered from the flow of air downstream of the electrically heated catalyst and transferred to at least one other vehicle system to provide thermal energy to the vehicle system, such as an engine coolant for a cabin heating system or a transmission fluid for a drivetrain transmission system.

摘要： A catalyst heating system includes a monitoring module, a mode selection module and an electrically heated catalyst (EHC) control module. The monitoring module monitors at least one of (i) a first active volume of a catalyst assembly in an exhaust system of an engine and (ii) a first temperature of a non-EHC of the catalyst assembly. The mode selection module is configured to select a non-EHC radiant heating mode and generate a mode signal based on the at least one of the first active catalyst volume and the first temperature. An EHC control module increases temperature of the EHC to an elevated temperature that is greater than a stabilization temperature based on the mode signal. The stabilization temperature is greater than a catalyst light off temperature.

摘要： A method of treating emissions from an internal combustion engine of a hybrid vehicle includes directing a flow of air created by the internal combustion engine when the internal combustion engine is spinning but not being fueled through a hydrocarbon absorber to collect hydrocarbons within the flow of air. When the hydrocarbon absorber is full and unable to collect additional hydrocarbons, the flow of air is directed through an electrically heated catalyst to treat the flow of air and remove the hydrocarbons. When the hydrocarbon absorber is not full and able to collect additional hydrocarbons, the flow of air is directed through a bypass path that bypasses the electrically heated catalyst to conserve the thermal energy stored within the electrically heated catalyst.
