摘要： A system and method of engine thermal management. Energy may be received from a solar energy source electrically connected to a vehicle propulsion system. At least some of the energy from the solar energy source may be used to heat a component of the vehicle propulsion system. A control module may provide at least some of the energy from the solar energy source to a heater, for example, to heat a component of the vehicle propulsion system prior to starting the vehicle propulsion system. The heater may heat the vehicle propulsion system to temperatures within a predetermined range associated with optimal efficiency of the vehicle propulsion system.

摘要： A spark-ignition, direct-injection internal combustion engine is coupled to an exhaust aftertreatment system including a three-way catalytic converter upstream of an NH3-SCR catalyst. A method for operating the engine includes operating the engine in a fuel cutoff mode and coincidentally executing a second fuel injection control scheme upon detecting an engine load that permits operation in the fuel cutoff mode.

摘要： A method for controlling ammonia generation in an exhaust gas feedstream output from an internal combustion engine equipped with an exhaust aftertreatment system having a first aftertreatment device includes executing an ammonia generation cycle to generate ammonia on the first aftertreatment device. The ammonia generation cycle includes monitoring an air-fuel ratio in the exhaust gas feedstream at a first location in the exhaust aftertreatment system, and monitoring an air-fuel ratio in the exhaust gas feedstream at a second location in the exhaust aftertreatment system. The air-fuel ratio at the first location is compared to the air-fuel ratio at the second location. If the air-fuel ratio at the second location is richer than the air-fuel ratio at the first location, operation of the engine is adjusted until the air-fuel ratio at the second location is equal to the air-fuel ratio at the first location.
