- the paticle refill 3 is composed of a material such as cordite, so that the gas flowing into the gas 60 will come into contact with the surrounding gas 64 as indicated by the arrow in 2B). Spills in. O for this pastry refill 3
- Both O and O5 are made up of, for example, aluminum.
- Figure 3 shows the faces of these faces 45.
- noble metal 46 is dispersed on the surface of catalyst 45.
- a layer of O 47 is formed on the surface of the catalyst 45.
- P is used as the noble metal 46, and the constituents of O 47 are, for example, potassium natrium a, cesium CS, alkalium varieties such as Ba Ba, and lucium Ca. And at least one selected from earth such as lanthanum a yttrium Y.
- the ratio of the air and (hydrogen chloride) supplied in the air passages of the air passages, the combustion 2 and the particulate flow 3 is called the exhaust gas, and O 4 7 is the exhaust gas.
- the reaction proceeds in reverse (O, O) because the oxygen concentration in the exhaust gas decreases. After that, it is released from O 47 in the form of glass ions OO, in O 47.
- the O released at is originated by CC contained in the exhaust gas.
- the fuel is supplied from the fuel supply 7 to make the gas rich in time and thereby release O 4 from O 47.
- exhaust gas contains S O and S O.
- This S O trap consists of, for example, a cam-made monolith medium and has a large number of gases that extend straight in the direction of the S O trap line. Like this S O tiger
- the When the is composed of a cam-made monolithic medium, it is made of, for example, alumina on the peripheral wall of the gas, and 4 shows the surface of this 50 plane part in the figure.

- Point 5 of the S O trap is basic.
- Fig. 4 the SO level captured in Cot 5 is shown. As you can see from 4 The area near SO plane 5 is the highest, and becomes lower as you go to. If the SO degree in the vicinity of the surface of coat 5 becomes higher, the basicity of the surface of coat 5 weakens and the SO force weakens. When the S force weakens, it will flow into some SO chelates 3 contained in the exhaust gas, and will start to be absorbed by o 47.

- the fuel supply 7 is arranged in the exhaust pipe 2 between the SO trap baticle refill 3 and the o trap 4 7 and O is released.
- the particulates and particles contained in the exhaust gas are subjected to the bacteriolite fill 3 Z and are sequentially converted.
- the amount of the particulate matter to be treated becomes larger than that of the particulate matter to be reduced, the particulate matter gradually accumulates on the baticle reticle 3, and the increase in the quantity of the particulate matter causes a decrease in force. I will end up. Therefore, when the volume of the child matter increases, the accumulated child matter must be removed.
- the degree of the Patti quilt fill 3 is raised to 600 with the excess air, the accumulated particulate matter is oxidized, and is removed.
- the amount of child substances exceeds the permissible amount, the temperature of the chelating filter 3 is increased under the exhaust gas line so that the accumulated child substances are removed. Physically, it was detected by the differential pressure sensor 27.

- the lowest catalyst In order to cause the exhaust gas to be converted into the exhaust gas, the method of the after-treatment charge is re-established so as to supply the after-treatment charge necessary for the gasification to the catalyst with the lowest level.
- the case when the deviation exceeds the predetermined case, the case is the lowest and therefore the most effective use for conversion is selected, and the selected exhaust gas Aftertreatment supplies are provided in a manner that is optimal for converting the exhaust gases selected to carry out the conversion. In this way, the amount of post-treatment charges can be minimized while securing exhaust gas.
- the SO sensor is used as sensor 20. It is used and whether or not it has changed is detected by this SO sensor 8.
- So degree detected by So sensor 8 exceeds the predetermined degree, it is judged that the So trap has changed, and when the So concentration detected by S sensor 9 exceeds the predetermined degree. It is judged that the chelating agent was converted to 3 O, and when the SO concentration detected by the SO sensor 20 exceeded the predetermined level, it was judged that O 5 was converted to O 5.
- the inflowing gas becomes rich at one time, and at this time, O is released from the upstream O 3. In this case, it is used for O and O from all upstream O 3 added from the fuel supply 7.
- the downstream O 5 is responsible for the conversion of the exhaust gas, and at this time, the O 2 in the gas and the emission are downstream. , 5.
- the added fuel is added to the downstream.
- the gas rich when the fuel is added from the fuel supply 7 is set to be higher than that shown in Fig. 7.
- the interval between riches should be short, or if the interval between riches should not be changed when the exhaust gas richness is increased, the interval between riches should be lengthened as shown in 8B).
- 0 indicates the post-processing device routine.
- step 0 3 it is judged if O OX exceeds the allowable X. In case of Z OX X, set to step 07. On the other hand, in the case of Z OX X, it proceeds to step 04 and it is determined whether or not the upstream O 3 has been transformed. When O 3 has not changed, the routine proceeds to step 5, where the rich 1 shown in 7 is performed, and then the routine proceeds to step 07. On the other hand, upstream O
- the sensor 27 detects the A P of the patch cartridge file 3. Then, at 08, it is determined whether or not A P exceeds the allowable P X, and when it becomes A P P X, the routine proceeds to 09, where the patty refill 3 is controlled. This is done by supplying the gas from the gas supply 7 while holding the gas flowing into the battery refill 3. On the other hand, when it is judged that the downstream O 3 has been converted to Step 0 0, the process proceeds to Step 0 and the fuel processing shown in 9 is performed.
