Example

Examples 1 to 5 and Comparative Examples 1 to 5

[0030]The gasoline fuel compositions of Examples 1 to 5 and Comparative Examples 1 to 5 were obtained by blending two or more components selected from butane, isomerate, alkylate, light naphtha, toluene distilled from a sulfolane extractor, toluenes distilled from an aromatic recovery unit, aromatics including a large amount of aromatics having carbon number of 9 or more, light cracked gasoline including a large amount of linear olefin having a terminal double bond, and heavy cracked gasoline. As additives, the same amount of a PEA / PIBA detergent was added in Examples 1 to 4 and Comparative Examples 1 to 5, and a PEA detergent and a friction modifier were added in Example 5. The cleaning performance of the gasoline fuel compositions of Examples 1 to 5 and Comparative Examples 1 to 5 was measured as follows. The results are shown in Table 3 and Table 4. The content of the linear olefin having a terminal double bond in the gasoline fuel c...

Abstract

A gasoline fuel composition includes 1.0 vol % or less of benzene, 2.8 to 30.0 vol % of aromatics having a carbon number of 9, 0.5 to 3.0 vol % of aromatics having a carbon number of 10, and olefins. The olefins include a linear olefin having a terminal double bond, the liner olefin being included in a proportion of 1.0 to 2.0 vol % in the gasoline fuel composition.

Description

TECHNICAL FIELD[0001]The present invention relates to a gasoline fuel composition constituting gasoline fuel for use in a gasoline engine provided in an automobile or the like.BACKGROUND ART[0002]It is known that adhesion of a heavy fraction and olefins included in gasoline which is fuel as deposits to an intake system of a gasoline engine, particularly to an intake valve, adversely affects combustion performance, emission performance and driving performance because the optimum air-fuel ratio of the engine cannot be kept. Accordingly, adjusting the composition of gasoline fuel, in particular regular gasoline, to a composition which is unlikely to generate deposits has been attempted (e.g., Patent Literature 1). Particularly in premium gasoline, a detergent is commonly added.[0003]The detergent has a function of removing deposits or preventing adhesion. A surfactant including such as amines or amides as an active ingredient can be used as the detergent as described in “Qualities and ...
