摘要：
Methods and systems are provided for cooling an aftertreatment device with exhaust gas. In one example, an exhaust system comprises a recirculation passage branching from an EGR passage from downstream of an EGR cooler to a portion of an exhaust passage between the EGR passage and an aftertreatment device. In one example, the aftertreatment device is an SCR device.
