Abstract:
An exhaust purification system includes an exhaust passage. Exhaust gas flows through the exhaust passage. A burner is arranged in the exhaust passage. A combustion space for fuel in the burner is a part inside the exhaust passage. A NOx adsorbent is located downstream of the combustion space in the exhaust passage. The NOx adsorbent adsorbs nitrogen oxide contained in the exhaust gas. A selective reduction catalyst is located downstream of the NOx adsorbent in the exhaust passage. An adding valve is located between the selective reduction catalyst and the combustion space in the exhaust passage. A connection passage is connected to the adding valve. Urea water flows through the connection passage toward the adding valve. A part of the connection passage runs through the combustion space.

Claim (Index 3):
The exhaust purification system according to  claim 2 , wherein\n the selective reduction catalyst is a downstream selective reduction catalyst, the adding valve is a downstream adding valve, the connection passage is a downstream connection passage for the downstream adding valve, an upstream selective reduction catalyst is integrated with the DPF, wherein the upstream selective reduction catalyst is located upstream of the downstream selective reduction catalyst in the exhaust passage, the exhaust purification system further comprising: an upstream adding valve located upstream of the upstream selective reduction catalyst in the exhaust passage; and an upstream connection passage for the upstream adding valve connected to the upstream adding valve, wherein urea water flows through the connection passage toward the upstream adding valve, and a part of the upstream connection passage runs through the combustion space.
