摘要： An exhaust gas aftertreatment system for an internal combustion engine has an exhaust system that can be connected to an outlet of the internal combustion engine. A three-way catalytic converter that is situated close to the engine and, downstream from the three-way catalytic converter that is situated close to the engine, a second catalytic converter and a particle reduction device are arranged in the direction in which an exhaust gas of the internal combustion engine flows through an exhaust gas channel of the exhaust system. A fuel injector is arranged on the exhaust gas channel so as to inject fuel downstream from the three-way catalytic converter that is situated close to the engine and upstream from the second catalytic converter, and the exhaust system comprises a secondary air system with which secondary air can be blown into the exhaust gas channel downstream from the three-way catalytic converter that is situated close to the engine and upstream from the second catalytic converter.

摘要： A method to control a burner for an exhaust system of an internal combustion engine with an exhaust gas after-treatment system including at least one catalytic converter. The method provides the steps of calculating the thermal power needed to reach the nominal operating temperature of the at least one catalytic converter and determining an actual number of revolutions with which to operate a fresh air pumping device based on the sum of a nominal number of revolutions, a closed-loop contribution of the number of revolutions with which to operate the fresh air pumping device, and a further contribution of the number of revolutions with which to operate the fresh air pumping device in order to ensure optimal thermal power exiting the burner.

摘要： Methods and systems are provided for routing secondary air to engine an exhaust system during a cold-start condition to reduce tail pipe emissions. In one example, a method may include operating a pump of an evaporative leak check module (ELCM) in a positive pressure mode and routing pressurized air to the exhaust passage upstream of an exhaust catalyst via an air conduit housing a first valve.

摘要： The present invention is directed at the integration of a solid oxide fuel cell (SOFC) into the exhaust stream of an internal combustion engine aided by the upstream injection of a fuel, such as a hydrocarbon fuel. The internal combustion engine may be advantageously operated in a lean condition while the SOFC receives the hydrocarbon fuel to promote and maintain optimized fuel cell operation.

摘要： A holding device for an injection valve of an exhaust-gas burner of a motor vehicle includes a receiving section and a cooling-water jacket. The receiving section is shaped such that it can receive a front end of the injection valve. The cooling-water jacket extends around the receiving section and is shaped such that, after the holding device has been mounted on the exhaust-gas burner, the cooling-water jacket, together with a corresponding cooling-water jacket of the exhaust-gas burner, forms a cooling-water chamber of the exhaust-gas burner.

摘要： A vehicle engine system includes an internal combustion engine, an air induction system configured to supply intake air to the internal combustion engine, and an evaporative emissions control (EVAP) system is configured to selectively supply purge fuel vapor to the EHC for subsequent combustion and rapid heating to a predetermined catalyst light-off temperature. The system additionally includes a booster configured to charge the intake air, and an engine bypass conduit fluidly coupled between the booster and the exhaust aftertreatment system. When the internal combustion engine is off, the booster selectively supplies a flow of intake air through the engine bypass conduit to the exhaust aftertreatment system. The flow of intake air draws purge fuel vapor from the EVAP system into the exhaust aftertreatment system.
