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： An engine system includes a turbocharger (16), an exhaust gas control apparatus (81), a fuel addition device (82), a heating unit, and an ECU. The turbocharger includes a variable nozzle mechanism (34). The exhaust gas control apparatus is disposed on an exhaust downstream side of the exhaust turbine in an exhaust passage. The fuel addition device is configured to add a fuel to the exhaust gas of the engine to recover the function of the exhaust gas control apparatus on a further exhaust upstream side than the exhaust turbine. The heating unit is configured to heat the link chamber (52). The ECU is configured to execute heating control for controlling the initiation and the stopping of heating by the heating unit and execute the heating control in a period overlapping with at least part of a period when the addition of the fuel by the fuel addition device is executed.
