Definitions
- the present invention relates to a gasoline fuel composition constituting gasoline fuel used in a gasoline engine mounted on an automobile or the like.
- the detergent has a function of removing deposits or preventing adhesion thereof.
- amines, Surfactants containing amides as active ingredients can be used.
- Patent Document 2 contains a friction modifier and a cleaning dispersant and satisfies predetermined properties, so that the cleaning performance of the intake valve deposit is high and the exhaust gas reduction effect is achieved. It has been proposed to obtain an excellent gasoline composition.
- the cleaning effect of the intake valve deposit by the cleaning agent improves as the amount added increases.
- excessively increasing the amount of the cleaning agent which is a polymer compound, is a non-volatile property in gasoline fuel oil.
- the tendency of the engine to malfunction is increased on the contrary, such as increasing the amount of substances and increasing the adhesion of the intake valve shaft and the deposit in the combustion chamber (combustion chamber deposit).
- This non-volatile substance can be evaluated as a so-called “unwashed real gum” before washing the evaporation residue with heptane among the real gum test methods in fuel oil.
- the upper limit value of the unwashed actual gum is determined together with the actual gum. Therefore, there is a problem that the amount of detergent that can be added is limited by the unwashed actual gum, and the cleaning effect obtained is limited.
- an object of the present invention is to provide a gasoline fuel composition having a high cleaning effect.
- the present inventors have conducted extensive research and found a gasoline fuel composition having a high cleaning effect. That is, the present invention has a benzene content of 1.0% by volume or less, an aromatic content of 9 carbon atoms of 2.8-30.0% by volume, and an aromatic content of 10 carbon atoms of 0.5-3.0% by volume.

- the aromatic component is preferably contained in the gasoline fuel composition at 33.0 to 46.0% by volume, more preferably 34.0 to 46.0% by volume. When there is much aromatic content, the amount of deposit production may increase.
- the aromatic component includes benzene, which is an aromatic component having 6 carbon atoms.

- the cleaning performance tends to be higher when the aromatic content has 9 carbon atoms, but if it is too much, the particulate matter may increase.
- the aromatic component having 9 carbon atoms includes monoalkylbenzene i-propylbenzene and n-propylbenzene; dialkylbenzene 1-methyl-2-ethylbenzene, 1-methyl-3-ethylbenzene, and 1-methyl- 4-ethylbenzene; and 1,2,3-trimethylbenzene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene, which are trialkylbenzenes.
- the sum of the content of dialkylbenzene having 9 carbon atoms and trialkylbenzene is preferably 2.0% by volume or more. Since aromatics having a plurality of alkyl groups are superior in oxidation stability to monoalkylbenzenes, they are less likely to deposit. Therefore, it is preferable to increase these ratios.

- the aromatic content of 10 carbon atoms is 0.5 to 3.0% by volume, preferably 0.5 to 2.5% by volume, more preferably 0.5 to 2.2% by volume. It is. If the aromatic content of carbon atoms is large, deposits are likely to be generated.

- Indans are preferably 0.4% by volume or less, more preferably 0.2% by volume or less, in the gasoline fuel composition. Indanes are poor in oxidation stability and have a high boiling point relative to their molecular weight, so they tend to deposit at the ambient temperature of the valve.

- the linear olefin having a double bond at the terminal is, for example, an olefin having 4 to 6 carbon atoms.
- a straight-chain olefin terminated with a double bond has a remarkably fast combustion rate and burns quickly in the combustion chamber. Therefore, when a certain amount of olefin having a double bond at the terminal is present, unburned substances that become deposit precursors can be reduced, and formation of deposits can be prevented.
- the content of the straight chain olefin having a double bond at the terminal is, for example, increasing the mixing amount of the catalytic cracking gasoline base material, or mixing the gasoline base material having a low concentration of the straight chain olefin having a terminal double bond. It can be adjusted by changing the amount.
