Claims

[Scope of utility model registration request]

The exhaust port 4 of the exhaust reburner 3 is connected to the exhaust outlet 2 of the water-cooled engine 1, and the exhaust introduction lower of the heat exchanger 6 for exhaust heat recovery is connected to the exhaust outlet 5 of the exhaust reburner 3. The exhaust reburning chamber 8 in the reburner 3 is surrounded by a cooling water chamber 10, and the outlet 12 of the heat recovery channel 11 of the heat exchanger 6 is connected to the cooling water chamber 10 of the exhaust reburner 3 through the communication port 14. The communication port 14 is provided in the connection part 15 between the exhaust reburner 3 and the heat exchanger 6, and the outlet 16 of the cooling water chamber 10 is connected to the side of the exhaust inlet 4 of the exhaust reburner 3. The inlet 18 of the water jacket 17 of the water-cooled engine 1 is opened in parallel to the side of the exhaust outlet 2 of the water-cooled engine 1, and the outlet 16 of the cooling water chamber 10 is opened in parallel to the inlet 18 of the water jacket 17. The exhaust gas recovery device for a water-cooled engine is characterized in that an outlet 19 of a water jacket 17 is communicated with an inlet 21 of a heat recovery channel 11 of a heat exchanger 6 via a heat recovery tank 20 by a communication path.
