| 摘要 | Methods and systems are provided for controlling an engine in a vehicle, the engine having a turbocharger, and a particulate filter upstream of a turbocharger turbine. In one example, the method comprises, under selected boosted operating conditions, injecting a reductant upstream of the filter during an exhaust stroke to generate an exothermic reaction at the filter. | ||

| 主权项 | 1. A method for an engine in a vehicle having a turbocharger and a particulate filter upstream of a turbocharger turbine, comprising: when boost generated by the turbocharger is below a threshold, injecting a reductant via an injector upstream of the particulate filter during an exhaust stroke to generate an exothermic reaction at the particulate filter, the injected reductant not being combusted in an engine cylinder; and when boost is above the threshold, stopping the injection. | ||
