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.
