  "textContent": "A control device for an engine, capable of accurately estimating the quantity of exhaust heat from the engine and performing engine control which improves the exhaust quality and fuel consumption of the engine in various operating conditions thereof, by using the accurate extimated value of the quantity of exhaust heat. A control device for an engine is provided with an exhaust flow rate sensor for directly sensing the flow rate of exhaust gas discharged from the engine, an exhaust temperature estimating device for sensing or estimating the temperature of the exhaust gas discharged from the engine, and an exhaust heat quantity estimating device for estimating, based on an output of the exhaust flow rate sensor and an output of the exhaust temperature estimating device, the quantity of heat of the exhaust gas discharged from the engine.",
