- the present invention relates to a technique for improving the detection accuracy of a densitometer that detects the concentration of a liquid reducing agent from the heat transfer characteristics between the two.
- Patent Document 1 An exhaust purification device disclosed in Japanese Patent Laid-Open No. 2000-27627 (Patent Document 1) has been proposed as a catalyst purification system for removing NOx in engine exhaust.

- Possible power to thaw the reducing agent The following problems may occur. That is, if there is a gap between the densitometer and the box-shaped member, when the reducing agent container is filled with the liquid reducing agent, bubbles enter the box-shaped member together with the liquid reducing agent, Bubbles may adhere to the detector. If air bubbles adhere to the detector of the densitometer, the heat transfer characteristics between two spaced points will change, and the concentration detection accuracy will be greatly reduced.

- the reducing agent supply device 28 is controlled by a control unit 32 having a built-in computer, and supplies an aqueous urea solution corresponding to the engine operating state to the injection nozzle 18 while mixing with air.
- the urea aqueous solution injected and supplied from the injection nozzle 18 is hydrolyzed by the exhaust heat and the water vapor in the exhaust to generate ammonia. It is known that the generated ammonia reacts with NOx in the exhaust gas in the NOx reduction catalyst 20 and is purified to water and harmless gas.

- the water level gauge 38 has a circular inner cross section and an outer electrode arranged concentrically to detect the water level of the urea aqueous solution.
- a detection unit 38B including an inner electrode and an outer electrode is suspended from the bottom of 24A.
- the densitometer 40 detects the concentration of the urea aqueous solution also by the temperature transfer characteristic force between two spaced points.
- the base 40A force column 40C is used so that the detection unit 40B is located at the bottom of the container body 24A. Thus, the detection unit 40B is suspended.

- the heat exchange ⁇ 44 is supported by the bracket 46 fixed to the canopy 36 with its bent end 44 ⁇ , so it is supported and fixed to the canopy 36 at three points, thereby increasing its mounting rigidity. be able to.
- the urea aqueous solution supply port 36C is connected between a water level meter 38 and a concentration meter 40, and a suction pipe 48 for sucking the urea aqueous solution from the bottom of the container body 24A.
- the suction pipe 48 is welded or brazed to a pipe of heat exchanger ⁇ extending from the engine cooling water inlet 36A to the bottom of the container body 24A while being partly welded, and formed at the tip of the pipe.
- the inlet 48A opens between the water level gauge 38 and the densitometer 40 in a downward direction. The tip is bent from the middle.
- a protector 50 is disposed as a box-shaped member that surrounds the water level meter 38, the concentration meter 40, and the suction pipe 48 and that can confine the heat released from the heat exchange.
