<p>PURPOSE: Fuel composition for the fuel supply internal combustion engine, additive concentrate and fuel additive compound are provided to reduce the amount of deposit formed at the fuel injector and effectively washes the dirty fuel injector enough to provide the improved power recover to engine. CONSTITUTION: Fuel composition for the fuel supply internal combustion engine comprises main amount of fuel, additionally an effective amount of the third hydrocarbyl amine and the quaternary ammonium salt of hydrocarbyl-substituted alkyl-hydroxybenzoate. Hydrocarbyl-substituted alkyl-hydroxybenzoate comprises more than one hydrocarbyl substituent which provides total 8 to 200 of carbon atoms. However, more than one hydrocarbyl substituent does not contain sulfur, oxygen or nitrogen atom.</p> |
