こと、さらに被毒物質（Ｓ。Conventional exhaust gas purification devices for gasoline-powered vehicles include those using catalysts and afterburner systems. The catalytic system used an oxidation catalyst to deal with CO and ■-IC in exhaust gas, and a reduction catalyst to deal with NOx. A three-way catalyst system is used to react each substance using three catalysts.This catalyst system is currently in the research stage and has not been put to practical use. When using the catalyst, the load conditions on the catalyst change significantly, so the catalyst must be able to handle the accompanying temperature changes, and it is also important that the catalyst is free from poisonous substances (S).

。Because it is used in exhaust gas containing compounds such as PB and Cu, it has the ability to maintain its activity level for a long time even if these substances inhibit catalyst activity and cause catalyst deterioration. Don't be afraid. (In engines, catalysts are required to have a long service life.) Currently, the service life of a catalyst under such an environment is about one year.

気ガス出口４から初出するものである。FIG. 1 is a structural diagram of an exhaust gas purification device using a catalyst. The principle is to surround the catalyst 1 carrier with a heat insulating wall 2, introduce exhaust gas there from the exhaust gas population 3, perform a oxidation reaction or a ring reaction with the catalyst 1, and release it as clean exhaust gas from the exhaust gas outlet 4. This is the first time it has been released.

It is difficult to keep money. In addition, since it is processed in the exhaust gas passage, engine performance may be affected.pt'l) f
Give x. Particulates ejected from a diesel engine? It is necessary to keep the vessel at a temperature close to 81,000C (the reaction temperature of amine in particulates is already about 1,000iC), but with this afterburner method, it is difficult to keep the vessel in such a vortex.
Therefore, there is a possibility that the particulate will be ejected before the main rod reacts, so it is not possible to achieve a sufficient effect with a dog.

くように４１１１成されている。In addition, in 1985-65214, there is shown an exhaust gas purification system [J] for internal combustion engines having a one-piece bank filter. In addition to inserting the ventilation girder, inside the cleaning cylinder, which has an exhaust gas inlet at the front end and an exhaust port at the rear end, there are 9 plates, a condensation force, a bolt, and a second plate. The expansion chamber and exhaust chamber are arranged in the same order, and the entire inner cylinder filled with (i11 fruit 4) is installed inside this exhaust tail.Then, at the rear end of this inner cylinder, a part of the inner cylinder is installed. The pack filter is installed so that it can rotate freely, and it automatically rotates at a slow speed when the vehicle is running or when the engine is running or when the engine is running. 4111 is constructed to blow and melt the layered soot and guide it to the reprocessing chamber.

The moisture that collects during the cooling process is heated by the cold air from the cooling ventilation pipe, which dampens the collection material inside the bucket, and the soot adheres to the collection material and is difficult to remove. This condition causes eyelids. A similar thing happens with pack filters. Even the soot and soot itself tend to accumulate in the fruit or in the pipes and block the pipes, and for this reason, it is necessary to remove them without causing any damage to the pottery material. However, processing capacity rapidly decreases over time. In addition, the clogging increases the pressure loss in the p-exhaust gas passage, which causes a decrease in engine performance.

Jij U. Moreover, the publications such as the period of the father's lordship and the lord's chivalry of the bed are also gaudy, making maintenance extremely difficult. Also,
Since carbon particles are captured and burned in the exhaust gas passage, the pressure in the exhaust gas passage increases while the process is being carried out, resulting in a decrease in engine performance. Furthermore, with such equipment, when heating the floor with heating compromise,
Because the floor is made of wire mesh, it has poor thermal conductivity, and in order to transfer all of the heat to the gas and heat it, the surface area of the heating table must be extremely large. Processing efficiency is poor.

る構造としている。Since the reaction temperature of harmful VJ amines is approximately 1000C, all methods of removal by combustion were adopted. Furthermore, since the size of particulates varies depending on the operating condition of the engine, a filter is used to capture all of the particulates before heating, allowing sufficient reaction time for the particulates. Further, in the present invention, in addition to treating particulates, in order to minimize the adverse effect on engine performance, the filter that captures all the particulates is moved outside the exhaust gas passage to react with the particulates.

By changing the filter shape to match the installation space of ial 10, it can be made more compact than the 10-karat gold exhaust pipe. In addition, I made it yellow in Fig. 61, Fig. 7, ff14 (it is also possible in I'l construction. However, in this case, unlike the lifting platform where the filters 11 and 12 are moved up and down, it is not possible to return them with chalk. Therefore, in this case, as mentioned in MiJ, it is not safe to use a spring or the like to pull the y-high part of the filter mounting plate opposite to the wire connection part.

きるという効果かめる。As explained above, the uninvented exhaust gas purification device for a diesel engine includes a filter for capturing particulates in the exhaust gas passage, and a filter for trapping particulates in the particulate processing chamber. Since the exhaust gas is configured to burn and remove particulates, it is possible to reliably capture and dispose of particulates in the exhaust gas. In addition, even during the treatment of particulates, there is no adverse effect on the engine, and furthermore, the present invention has the advantage that it can be made into a structural black matrix.
