Abstract:
ProblemA detergent friction modifying agent having both a detergent performance that ameliorates and prevents degradation over time that is caused by deposits in the engine, and a friction reducing effect that lowers frictional resistance in the engine; a fuel additive that improves drivability with a good balance over the entire range of engine speeds, and provides engine characteristics such that, over the entire range of driving speeds, the engine-braking characteristics are such that the feeling of free running will be strongly produced, such that a fuel consumption improvement effect is produced in actual vehicles that is greater than the values produced on the test bench, and which also has storage stability; and a fuel composition containing the same.SolutionThe present invention is characterized by containing a polyetheramine carboxylic acid salt; the fuel additive of the present invention is added to fuel at 0.5 wt % or less.
