Description of the Related Art In recent years, various additives have been added to light oil for diesel engines in order to adjust various characteristics in order to improve its performance. In this case, the viscosity is usually reduced by diluting with a solvent to facilitate handling. However, there are various types of the above-mentioned additives, and different manufacturers may be used for each of them, or the solvent used may be different even if they are of the same manufacturer. In such a case, mix these additives. If it is used, it may be difficult to mix and use the additives such as precipitation of each additive component. Further, such a precipitate reduces the action of the additive, and when it is added to light oil, the amount of the active ingredient added becomes uncontrollable, and there is a problem that the filter of the addition facility is likely to be clogged. It was happening. As an example,
In order to comply with exhaust gas regulations, it is also required to reduce the sulfur content in diesel engine diesel oil, but when deep desulfurization is performed to reduce such sulfur, lubrication of the resulting diesel fuel product is required. It has been known that performance is significantly reduced. That is, due to such deterioration in lubrication performance, wear of parts of a fuel injection pump of a diesel engine lubricated with light oil as fuel increases, resulting in inconveniences such as engine rotation failure and drivability deterioration. It has been reported. In such a system, a lubricity improver or the like is added to improve lubricity, but when the above additives are added together with other required additives, These problems are noticeable.
