になる。 The filter trap can be of any type as long as it collects particulate matter, but as particulate matter is collected in the filter trap during engine operation, the filter becomes clogged and back pressure increases. As a result, engine performance decreases and even engine operation becomes difficult.

が限られ、しかも高価になるという問題がある。 As a method for promoting the reburning of particulate, a particulate reburning accelerator containing metals such as copper is added to the fuel, as proposed in JP-A-59-155527. It has been attempted to facilitate the reburning of curate on a filter, but in this method, the reburning accelerator is dissolved directly in diesel oil, so it must be made into an oil-soluble compound, and the metals that can be used are The problem is that compounds are limited and expensive.

実施上の難点もある。 In addition, Japanese Patent Application Laid-open No. 57-30523 discloses that when particulate in exhaust gas is collected in a heat-resistant filter and re-burned, an alkali metal compound is preliminarily impregnated into the filter, or particulate is A method is shown in which the particulate collected in the filter is burned by spraying an aqueous solution of an alkali metal compound onto the clogged filter.
However, with this method, it is difficult to uniformly disperse the alkali metal compound in the particulate, so there is a problem that the particulate does not burn smoothly, and the alkali metal compound is added to the filter. There is also the difficulty of implementation in that existing equipment must be modified in order to adopt a configuration that does.

はできない。 The particulate reburning accelerator used in the present invention is a water-soluble alkali metal compound or alkaline earth metal compound. Specific examples of such substances include sodium, potassium, and calcium carbonates, hydrogen carbonates, carboxylates, and hydroxides. In the present invention, such a reburning accelerator is used to increase the metal concentration of the fuel.
0.1mmol/ to 5mmol/, preferably
It is dissolved in water at a concentration of 2 mmol and supplied to the combustion system along with the fuel. The method of supplying the aqueous solution containing the reburning accelerator to the combustion system is to disperse the aqueous solution in light oil as an emulsion using an emulsifier, and to use the emulsion fuel thus formed in exactly the same way as ordinary diesel fuel. It is sufficient to supply it to the combustion system. In this case, no mechanical improvement of the engine is required and the existing engine can be used as is. In this method,
The optimal concentration of the reburning accelerator in the aqueous solution varies depending on the mixing ratio of the aqueous solution and light oil, and is preferably adjusted so that the final metal concentration is 0.1 to 5 mmol/distance to light oil. If the metal concentration is higher than this range, no particular improvement in the reburning effect of the particulate will be obtained, but rather combustion will be inhibited, which is undesirable. A sufficient reburning effect cannot be obtained by the accelerator. In addition, metal compounds must be dispersed in the fuel in the form of an emulsion, and simply adding water-soluble metal compounds to the fuel will not achieve uniform dispersion and will not achieve the intended purpose. Can not.

要するエネルギーなどを節約することができる。 In the present invention, after the reburning accelerator made of an alkali metal compound or alkaline earth metal compound added to the fuel is combusted in the engine, the reburning accelerator is Captured by particulate. The particulate that has captured this reburning accelerator is collected by a filter and combusted. in this case,
The particulate collected by the filter is
Because each particle contains a reburning accelerator,
It can burn very smoothly. That is, compared to the case where no reburning accelerator is added, when the accelerator of the present invention is added, the afterburning temperature of particulate is lowered, the load on the filter is reduced, and the particulate collecting and removal effect is improved. This improves the durability of the filter, and saves energy required for re-combustion, such as power for the heater or energy required to burn part of the fuel and heat the filter.
