In addition, the present invention relates to the use of a device for purifying exhaust gas in the engine for purifying exhaust gas, especially in the pre-waste recycling of diesel fuel)-a considerable part and method for purifying harmful exhaust gas, in particular, it refers to Exhaust gas of nitrogen oxides (NOx). In egr. A part of the exhaust gas from the engine is recirculated to an air inlet. It is known to use an exhaust gas purification device containing at least one converter unit, so that the gas component becomes a harmful substance with less harm to the environment. According to the practice, the converter unit generally contains a catalyst to convert the components in the exhaust gas into the lamp catalyst to become a harmful substance with less harm to the environment. Therefore, through this catalyst, carbon monoxide and carbohydrates can be converted into carbon dioxide or water. This requires that a certain amount of oxygen be contained in the exhaust gas. For this reason, an oxygen measurement unit is generally used in the exhaust gas flow from the engine, and this unit transmits an output signal. This transmission is based on the operation of the engine being controlled to achieve the required oxygen content.

^ 而且’可經由此觸媒而將氧化氮轉換成中性氮在廢氣中過多的氧將導致停止減少氧化氮，而此氧化減量將導致在上述廢氣中其他成份之轉換的反作用。但是，一最適的燃料系統之調節將導致上述有害成份的減少。經由使用 EGR技術，可更進一步達到氧化氮的減少。^ Furthermore, ‘the catalyst can be used to convert nitrogen oxides to neutral nitrogen. Excessive oxygen in the exhaust gas will cause the reduction of nitrogen oxides to stop, and this reduction in oxidation will lead to the adverse effect of the conversion of other components in the exhaust gas. However, the adjustment of an optimum fuel system will result in the reduction of the above-mentioned harmful components. By using EGR technology, nitrogen oxide reduction can be achieved even further.

Description of the invention (2) A quantity of fine particles. In the framework of representing the composition of microparticles, the particles it contains, such as ashes, organic residues (called SOF), are generated from fuel or oil. It is known to use simple different types of filters to separate the exhaust gas from the particulate components and release the exhaust gas. This filter is known to be reused, that is, it can be stored again without having to exchange it. This regeneration function is achieved by a conventional technique. The method is to heat the filter to a required level to cause the combustion of particulate components. The energy required for this combustion is very large. For some reason, 'according to the conventional technology, the use of a fixed filter is required, which is a static coupling engine' or removed from it, so that the heating element is connected to the electric power network. The required heating may then occur. It is therefore necessary to interrupt the operation. Another technique to achieve filter regeneration in an EGR recirculation duct (see US 5 207 734 and JP 833832 0) uses a catalyst upstream of the filter to provide heat from the catalyst to the filter. However, this leads to a reduction in filter regeneration ', especially when there is little recirculated exhaust gas under certain engine operating conditions. <Summary of the Invention> The object of the present invention is to improve the conventional technology to achieve effective filter regeneration and effectively purify NOx, carbon monoxide, hydrocarbons, particles, and the like. The purpose of the present invention is achieved by the features proposed in the first item of the patent application scope. Therefore, 'the design of the present invention is based on the concept of configuring a filter, so that the exhaust gas and heat generated in the conversion result of the converter unit can be converted from The filter unit is moved laterally into the filter, so that the conditions for transferring the filter are actually improved. It must be pointed out that in the EGR system, the recirculated exhaust gas changes depending on the operating conditions of the bow. "Under certain conditions, there is 500870 per unit time. Case No. 88122245 V. Description of the invention (3) Certain amount of exhaust gas By filtering only the exhaust gas that passes through the filter, if necessary, the filter may need to reach this temperature, the required filter is regenerated, and the particulate components are burned to cause certain conditions, which together cause the filtration The energy adjustment of the heating element of the device becomes a temperature at which regeneration occurs.

In the example according to Figs. 2 and 3, An Mengdi »^ ^ 丁丁文衮 The first and second flow paths 37 and 39 correspond to the mouth portions 40 and 41, so they can face the exhaust gas that arrives. FIG. 4 shows another modified embodiment of the present invention. Arrow 36 indicates how the exhaust from the engine arrives. These exhaust gases first flow through the second flow path 39 ,. A part of the exhaust gas that has passed through the converter unit 34, then moves to the first flow path 37, according to the arrow 42.

Downstream, here, the filter 33 and the converter unit 34 are parallel to each other and form a laterally overlapping configuration, so that the mouth portions 40 and 41 of the flow path are generally located on the same plane. The heating element 44 is adapted to provide thermal energy to the exhaust gas passing through the filter 33. The plus element 44 is only suitable for heating the recirculated exhaust gas entering the engine. Therefore, in the flow path 37, a heating element 44 is disposed upstream of at least one portion of the filter. In particular, it is suitable to appropriately configure the grommet 44 in the mouth 40 of the flow path 37. In the embodiment of FIG. 4, the corresponding phrase is also used, but as from the above description, the heating το member 44 'is positioned at the end of the converter unit 34', where when the total exhaust gas flow is taken into account, Arrow 36 positions this downstream. It is best that the hot element 44 is returned to the engine ’s non-sensing sensor to integrate the conversion catalyst action so that the exhaust gas leads to the amount of this filter 33 and, as for, the operation of the heating element, the air is introduced and recirculated to the nearby unit 34 In the structure, the heat input by the converter in the component is obtained by the converter and the catalyst junction unit.器 3 3。 When the machine 3 3. Local contact with the exhaust gas leads to a reduction in the addition of a certain part. It will have heat transfer. It is indicated that some temperature information related to the flow in the recirculation duct 10 is preferably controlled by the control unit. However, a temperature sensor can also be used. This is due to the fact that it has a catalytic conversion and therefore less harmful substances in the environment. Some heat. It is the heat of the exhaust gas that enters the filter 33, and this reversal relationship. The catalyst is an oxidation catalyst, which starts from page 11 500870

The catalyst structure is prepared so that a real catalyst material such as #metal is coated on a bottom material suitable for a large area. The shell medium structure can be connected through an appropriate mechanical connection component 45. The contact filter 33 includes a high temperature and Materials with good filtering ability. For example, in the case of ceramic materials, mineral fibers and metal fibers are quite useful. This material needs to tolerate the high temperature that can be induced when regenerating the filter. It is best to use a tube The element 46 separates the filter 33 and the converter unit 34, and the heating element 44 is positioned at one end thereof, and the other end is connected to the pipe 38 via a fixing joint 47. The tubular element 46 may be connected to the surrounding converter unit 34 via the fixing element 47. The filter 33 and the converter unit 34 are interconnected, so that heat transfer between them can be effected through heat conduction and / or radiation.

Description of the invention (9) The exhaust gas is released by separating the exhaust gas from the particulate components through the filter 33. This part of the exhaust gas flows through the recirculation duct and is recirculated to the air intake port 2 of the engine, so that 'corresponding to the exhaust gas purification equipment 3 1 can produce an egr function, and incidentally produce a good effect. The filter 33 has a high-efficiency filtering function, and can basically remove more than 90% of particulate components from the exhaust gas. These components are deposited on the filter material. The filter material is heated by the heat in the exhaust gas and is burned in the surrounding catalyst material, so that the filter 33 can achieve a better temperature rise effect than other ^ preparations. The filter is regenerated by the combustion of the fine particles deposited therein. If necessary, the temperature of the exhaust gas that reaches the boiler 33 through the heating element 44 through the heating element 44 in the environment can be increased to enhance the combustion effect. By an appropriate temperature measurement, the temperature in the filter 33 can be monitored. In this regard, it should be noted that the regeneration of the filter 33 may be performed continuously or intermittently. The degree of t indicates that it is possible that at least part of the catalyst is provided to the filter 33 ′ so that T can perform the filter transfer at a temperature lower than necessary. However, it is necessary to indicate that the filtering effect of the filter 33 is the most important, and the catalyst effect stated is a secondary effect. The surrounding area is also acceptable. In the embodiment illustrated in FIG. 4, the functions are the same, except that the exhaust gas passing through the converter unit 34 'is the portion that will pass through the filter 33'. f In particular, the above description is not intended to limit the scope of the present invention. The description in the text takes a diesel engine as an example, but it must be pointed out that the present invention can be used in other different types of engines. In addition, it should be noted that when the basic concept of the present invention is proposed, those skilled in the art may realize the filter 33 and the converter unit 34 of the other mode. Therefore, of course, multiple filters can also be provided, and
