  "textContent": "An exhaust system (16) for a compression-ignition engine (10) includes an exhaust gas after-treatment assembly, the after-treatment assembly comprising a catalyst device and an SCR device (34). The catalyst device comprises a three-way catalyst device (30) arranged upstream the SCR device (34) in close-coupled position with respect to the engine (12). The three-way catalyst reaches its operating temperature quickly due to its close coupled position and can therefore provide good NO x conversion during acceleration phases occurring shortly after a cold start when the engine is switched to an operation at »=1.",
