Abstract
A method for reducing the formation of combustion chamber deposits in an engine using a friction modifier for combustible fuels is provided. The friction modifier is prepared by combining a saturated carboxylic acid and an alkylated or alkoxylated amine. The particular selection of friction modifier enables a stable additive concentrate to be formulated providing a significant decrease in CCD without increasing the incidence of IVD deposits in combustion engines running on a fuel modified with the additive concentrate.
Claims1
A method for reducing the formation of combustion chamber deposits in an internal combustion engine having a combustion chamber, said method comprising combusting in said internal combustion engine a fuel composition comprising a hydrocarbonaceous fuel and a friction modifier, wherein the friction modifier is prepared by combining an amine selected from the group consisting of Isohexyloxypropylamine;
- 2-ethylhexyloxypropylamine;
- Octyl/Decyloxypropylamine;
- Isodecyloxypropylamine;
- Isododecyloxypropylamine;
- Isotridecyloxypropylamine;
- C12–C15 alkyloxypropylamine;
- Isodecyloxypropyl-1,3-diaminopropane;
- Isododecyloxypropyl-1,3-diaminopropane;
- Isotridecyloxypropyl-1,3-diaminopropane;
- 2-ethylhexyloxypropyl amine;
- Isopropyloxypropylamine;
- Tetradecyloxypropylamine;
- Dodecyl/tetradecyloxypropylamine me;
- Tetradecyl/dodecyloxypropylamine;
- Octadecyl/hexadecyloxypropylamine;
- Tetradecyloxypropyl-1,3-diaminopropane;
- and C12–C15 alkyloxypropyl-1,3-diaminopropane with a saturated carboxylic acid, whereby the formation of combustion chamber deposits in said engine is reduced relative to the formation of combustion chamber deposits in said engine combusting a fuel composition not containing said friction modifier.
