Water-soluble compounds of alkali metal compounds and alkaline earth metal compounds such as acid salts and hydroxides are dissolved in water at a concentration of 0.1 mmol/t to 5 mmol/1, preferably 2 mmol/1 relative to the fuel. It is supplied to the combustion system together with fuel in the form of The first method for supplying an aqueous solution containing a reburning accelerator to the combustion system is to disperse the aqueous solution in light oil as an emulsion using a dispersant such as an emulsifier, and then combust it in exactly the same way as normal diesel fuel. -+1 There is a way to do it. In this case, structural improvements to the engine are unnecessary, and the current engine can be used as is.
can do. In this method, the second method of adding the aqueous solution containing the aqueous solution neutralizing agent is to directly inject the aqueous solution itself into the intake vibe of the engine or into the cylinder through an injection nozzle. In this case, a current diesel engine with a water injection mechanism added will be used. In this method as well, the concentration of the reburning accelerator in the aqueous solution is determined in consideration of the ratio of the supply amounts of the aqueous solution and light oil so as to achieve the above-mentioned optimum addition amount.
