  "textContent": "An engine exhaust cleaning device is configured to prevent the temperature of a particulate matter filter (DPF) from rising sharply due to a reduction in the exhaust gas flow rate when a vehicle decelerates and shifts into idling operation during regeneration of the particulate matter filter (15). During regeneration of the particulate matter filter (15), the fuel cut (F/C) recovery engine speed used during deceleration is increased and the engine idling speed is increased for a prescribed amount of time when the engine idles.",
