The invention provides the use of an organic compound selected from a bicyclic monoterpene, substituted bicyclic monoterpene, adamantane, propylene carbonate and mixtures thereof, to improve the solubilization of a solid, fuel-soluble iron compound in a fuel composition or in a precursor liquid to be added to fuel composition.

Fuel additive compositions

The present invention provides a composition comprising: i) at least one compound of formula (I): wherein Rand Rare independently selected from a group consisting of hydrogen, unsubstituted or substituted Chydrocarbyl or a group of formula (II): wherein Q is a bond or an unsubstituted or substituted hydrocarbyl group; wherein Ris selected from a group consisting of hydrogen and unsubstituted or substituted Chydrocarbyl; wherein the R&#x2014;C&#x2014;Rbackbone is from 5 to 20 atoms in length; wherein each A and B is independently an unsubstituted or substituted unsaturated cyclic hydrocarbyl group; and wherein n is an integer from 0 to 10; and ii) a diluent or carrier; wherein the compound(s) of formula (I) is present in an amount sufficient to provide, at &#x2212;30&#xb0; C., at least 1 wt % of iron, based on the weight of the composition.

Composition

The present invention relates to iron-organo compounds and the use of such compounds in the regeneration of particulate filter traps in combustion systems such as high-compression spontaneous ignition engines. The iron-organo compounds have the formula X-Y where X represents the group of formula Y represents the formula each A and B is independently an unsubstituted or substituted aromatic carbon ring or an unsubstituted or substituted aromatic heterocyclic ring; the or each Z is independently an unsubstituted or substituted divalent hydrocarbyl group; n is 0 or an integer of from 1 to 10.

Compositions comprising dimeric or oligomeric ferrocenes

A process for reducing carbonaceous deposits caused by the combustion of heavy fuel oil in high-compression, spontaneous-ignition internal combustion engines involves adding an additive such as ferrocene or ethyl ferrocene to a heavy fuel oil having a density of 0.9 to 1.01 kg/dm.sup.3 in an amount of 1 to 100 ppm prior to combustion of the fuel oil and combusting the fuel oil in the high-compression, spontaneous-ignition internal combustion engine. The additive is dissolved in the heavy fuel oil.

Use of ferrocene

A device as described for direct addition of additive solids to liquid fuels, which solids are soluble in the fuel. For adding solids to fuel directly in the line leading to the combustion chamber or engine, the device includes a hollow body at least partially filled with the solid, whose lengthwise axis is at an angle .alpha. of 130.degree. to 170.degree. to the inflowing fuel and whose lower end, irrigated by inflowing fuel, has at least one opening through which the fuel can enter and leave the hollow body.

Device for adding additives to liquid fuels in the fuel stream

A device for direct addition of solid additives to fuels for internal combustion engines. In order to ensure a concentration of the solid additive in the fuel which is as constant as possible, the device has a cartridge at least partially filled with the solid additives and at least partially permeable to the fuel. The cartridge is located in a portion of the filling neck of a fuel tank.

Device for adding additives to liquid fuels

The invention relates to an apparatus and a method for direct addition of solid ferrocene to fuels. The liquid addition or fortification of fuels with ferrocene is known. The new apparatus and the new method enable an addition of solid ferrocene to fuels. The apparatus according to the present invention comprises a grinder being connected to a fuel conduit or a fuel tank, said grinder being filled with solid ferrocene. The apparatus further comprises a step motor being coupled to the grinder and includes a control means for said step motor. With respect to the method of the present invention it is proposed to measure the amount of fuel flowing through a fuel conduit, to determine the required amount of ferrocene therefrom and to add the so determined amount of ferrocene to the amount of fuel by actuating the grinder at the corresponding number of revolutions. The apparatus is preferably adapted to be installed in motor vehicles comprising an Otto-engine or a Diesel-engine in connection with a particle filter system being positioned downstream of the Diesel-engine or being adapted to be installed in a furnace for light or domestic fuel.
