Embodiment 1

[0087]

[0088] Polyetheramine, the fatty acid salt of oleic acid containing more than 50% of the polyetheramine as a polyetheramine carboxylate, and the polyetheramine are each added with 10% and 25% of nonylphenol as a base oil. The additive after the oxybutane polymer and the additive after adding 10% of the above polymer to the polyetheramine carboxylate were added to commercially available standard gasoline in equal amounts so as to become 2500 ppm based on the polyetheramine. The performance of removing deposits inside the intake valve and the combustion chamber was confirmed, and the results are shown in Table 1. Furthermore, two types of additives in which 500 ppm of polyetheramine was added in an equal amount were prepared as samples.

[0094]

[0095] Immerse the sediment of the suction valve in the stock solution of polyetheramine, polyetheramine oleate and polyetheramine caprylate at different temperatures to judge their dissolution status.

[0096] The polyetheramines and their salts used in the evaluation ([R 2 -O(AO)m-XH + ]), using the most balanced value R 2 =13, A=4 (alkylene group having 4 carbons), m=20, and X is a polyetheramine of the group when n=1.

[0101]

[0102] Polyetheramine, polyetheramine carboxylate (crude oleic acid, a mixture of fatty acids containing oleic acid as a carboxylic acid), fatty acid (crude oleic acid, a mixture of fatty acids containing the same oleic acid as the carboxylate) , polyetheramine cyclohexane salt, etc., and polyetheramine 1000ppm (concentration in standard gasoline) equivalent acid and salt, using a number of different engines to measure the actual fuel economy. Polyetheramine uses the R 2 =13, A=4 (alkylene group having 4 carbons), m=20, and X is a polyetheramine of the group when n=1.

Abstract

The present invention is: a cleaner / friction modifier having both a cleaning property for improving / preventing deterioration over time due to debris inside an engine and a friction-reducing effect for reducing frictional resistance inside the engine; a fuel additive that improves drivability in a balanced manner over the entire range of engine rotation rates, provides the engine characteristic that engine brake characteristics give a strong feeling of coasting over the entire traveling speed range, is able to obtain fuel efficiency-improving effects more than test bench numerical values in an actual car, and also is provided with storage stability; and a fuel composition comprising same. The present invention is characterized in comprising a polyetheramine carboxylic acid salt. No more than 0.5 weight% of this fuel additive is added to fuel.

Description

technical field [0001] An object of the present invention is to improve or prevent deterioration of fuel economy due to aging and aging of an engine, and to improve actual fuel economy. The fuel additive for internal combustion engines provided by the present invention can not only reduce the frictional resistance of the engine, but also change the characteristics of the engine brake to a characteristic different from the usual feeling, so as to give the driver the driving feeling of opening the accelerator as soon as possible. In addition, the present invention relates to a stable quality fuel additive as a mixture package and a fuel composition containing the additive. Background technique [0002] Gasoline engines have improved significantly in recent years. A wide variety of mechanisms have emerged that have been eye-opening in improving the fuel economy of gasoline vehicles. The driving force is divided into the following two categories: the improvement of combustion ...
