Definitions

  • the invention relates to an additive for unleaded petrol to prevent or reduce valve seat wear, which essentially contains at least one alkali metal or alkaline earth metal salt of an organic sulfonic acid and at least one ash-free detergent and optionally other known additives.
  • the invention also relates to a gasoline fuel containing this additive.
  • wear protection additives protect the exhaust valve seats of the petrol engines and enable the use of unleaded petrol also for the operation of end-of-life vehicles that are not yet specially equipped for the use of unleaded petrol.
  • alkali metal-containing additives have hitherto been proposed as additives for protection against valve seat wear.
  • EP 0 288 296 proposes a finely divided metal salt dispersion, in particular a dispersion of potassium borate, sodium borate, potassium carbonate and potassium bicarbonate, as an additive against valve seat wear.
  • the fuels for preventing or reducing the signs of wear on the valves and for simultaneously reducing the signs of corrosion contain alkali metal or alkaline earth metal salts of monoamides of dicarboxylic acids with 2 to 4 carbon atoms between the carboxyl groups or of amides of tri- or Tetracarboxylic acids, the amino nitrogen carrying at least one hydrocarbon group, which is optionally oxygen or amine substituted. Thanks to their detergent effect, these additives are also said to keep the engines clean.
  • EP-A1-0 307 815 (BASF) relates to fuels in which small amounts of copolymers of olefins and / or cycloolefins with maleic anhydride and / or copolymers of alkyl vinyl ethers and / or cycloalkyl vinyl ethers with maleic anhydride and / or copolymers of alkyl vinyl ethers and / or cycloalkyl vinyl ethers and olefins and / or cycloolefins with maleic anhydride are contained, the carboxyl groups being wholly or partly reacted to form alkali metal or alkaline earth metal salts and the rest of the carboxyl groups having alcohols and / or amines being converted into corresponding ester and / or amide groups and / or ammonium groups.
  • EP 0 342 497 (BASF) likewise describes the addition of copolymers of alkyl (meth) acrylates and / or vinyl esters from optionally monoethylenically unsaturated carboxylic acids, the carboxyl groups of the copolymers, for the purpose of preventing the signs of wear on the valves and at the same time reducing the signs of corrosion fully or partially reacted with alkali to form the alkali metal salts and the rest of the acid groups have been reacted with ammonia and / or amines to give the corresponding amide groups and / or ammonium salts.
  • EP-A1-0 207 560 (Shell) describes alkali metal and alkaline earth metal salts of hydrocarbon-substituted succinic acid as wear protection additives.
  • the hydrocarbon substituents on the or the alpha carbon atom (s) of this succinic acid have a length of 20 to 200 carbon atoms.
  • hydrocarbon-substituted succinic acid derivatives are the subject of extensive older and newer patent literature.
  • the imide derivatives of these substances are used alone or in combination with other additives because of their dispersing action.
  • EP-A-233 250 proposes a combination of alkali or alkaline earth metal-containing compositions and ash-free dispersants as an additive against valve seat wear.
  • alkali metal-containing compositions only the salts of organic alkylarylsulfonic acids are specifically mentioned; the dispersants are the known alkenyl succinimides already mentioned, which as a rule contain at least about 30 aliphatic carbon atoms.
  • PCT application WO 91/07477 is concerned with improving the ignition behavior of fuels and, as an addition in this regard, discloses alkali metal and alkaline earth metal salts of mono- or diesters of sulfosuccinic acid.
  • These compounds are succinic acid derivatives in which the carboxylic acid group (s) are esterified with hydrocarbon radicals and an alpha carbon atom of succinic acid is substituted by a sulfonic acid group.
  • These sulfosuccinic acid esters are in the form of alkali metal or alkaline earth metal salts.
  • the aim of the present invention was now to provide an inexpensive wear protection additive for unleaded gasoline fuels, which causes valve seat wear reduced or completely prevented on the engine output side and at the same time ensures that the engine is kept clean.
  • the entire range of tests for fuel components that are common today according to the prior art must also be complied with.
  • the new antiwear additives are thus characterized according to the invention in that they contain a neutral alkali metal and / or alkaline earth metal salt of a mono- or diester of sulfosuccinic acid of the general formula I. contain, in which R1 and R2 independently of one another represent hydrogen or an aliphatic hydrocarbon group, with the proviso that at most one of the radicals R1 or R2 is hydrogen, M represents an alkali metal or alkaline earth metal ion and n corresponds to the valence of M.
  • the aliphatic groups can be saturated or unsaturated groups, which can optionally also carry substituents.
  • suitable substituents are hydroxyl, ether, ketone, phenyl or ester groups, which can be the same or different on the two hydrocarbon groups.
  • Mono- or diesters of sulfosuccinic acid can be used, the ⁇ -position to the SO3 group Carboxyl group, the ⁇ -carboxyl group or both carboxyl groups, can be esterified with the same or different radicals.
  • the salts of the diesters of sulfosuccinic acid are preferred. They have proven to be soluble in gasoline to an extent that allows the desired amount of the alkali metal or alkaline earth metal additive to be adjusted without problems.
  • the chain length of the aliphatic hydrocarbon group in the ester radical is preferably 4 to 20 carbon atoms. Hydrocarbon radicals with a chain length of 6 to 13 carbon atoms, in particular with a chain length of about 8 carbon atoms, are particularly preferred.
  • the alkali metal salts of the sulfosuccinic acid esters are preferred, the potassium salts having proven particularly favorable for the purpose of protecting the outlet valves.
  • the salts of the sulfosuccinic acid esters also act as surface-active agents, which facilitates the formulation of additive packages for high demands on engine cleanliness.
  • detergents are all different Ashless detergents, such as long-chain amide-imide compounds, long-chain amines, polyethers or polyether amines are suitable.
  • Ashless detergents such as long-chain amide-imide compounds, long-chain amines, polyethers or polyether amines are suitable.
  • the polybutenamines in combination with the salts of the sulfosuccinic acid esters have proven to be particularly advantageous.
  • the detergents preferably have an average molecular weight of from 2000 to 3000.
  • the additives according to the invention can also contain other additives known per se. Frequently e.g. Corrosion protection is desirable or necessary.
  • carrier oils are also used. These either consist of mineral oil fractions or they are synthetic products, e.g. Poly alpha olefins. As a rule, it is the detergents that are formulated as a solution in a carrier oil and therefore incorporate this component into the additive package. In addition, the alkali metal component can also be easier to handle by adding a carrier oil.
  • the entire additive package can be mixed with a diluent, which may also contain aromatic components, for easier processing, solubility in petrol and lower viscosity at low temperatures.
  • a diluent which may also contain aromatic components, for easier processing, solubility in petrol and lower viscosity at low temperatures.
  • Aromatic kerosene can preferably be used for this purpose. With the help of such diluents, viscosity limits of around 800 cP at -20 ° C can be maintained, which are favorable for European conditions.
  • the quantitative ratios of alkali metal component to detergent are preferably in the range of 1: (8-15), these details relating to detergents which may contain a carrier oil.
  • the additive can contain 15% by mass to 40% by mass, preferably 30% by mass to 40% by mass, of an aromatic kerosene as a diluent.
  • a fuel for gasoline engines that contains an additive according to the invention meets the requirements placed on it if it contains 0.01 milligram atom (mVal) to 2.5 milligram atom (mVal) of alkali metal per kg of fuel.
  • the preferred range is between 0.02 mVal and 1.0 mVal, in particular between 0.07 mVal and 0.25 mVal alkali metal per kg of fuel.
  • a wear protection additive is created from the following components:
  • the alkali metal component consists of a potassium sulfosuccinic acid dioctyl ester. If this component is without carrier oil, it contains about 8.5% by mass of potassium.
  • the detergent is based on polybutenamine.
  • a portion of carrier oil comes from the detergent component, and the potassium sulfosuccinate can also be formulated with carrier oil.
  • the product contains an aromatic kerosene for dilution.
  • the mixing ratios in this specific example are as follows: 6.3 mass% K-sulfosuccinate component 70.4 mass% detergent component 23.3% by mass of kerosene
  • the potassium content of this additive is 0.31% by mass.
  • This additive is added in an amount of 1100 ml to 1000 liters of fuel, so that about 4 mg of potassium are contained per kg of fuel.
  • Test fuel Deposits: Gasoline (Eurosuper) without additives 350 to 700 mg / valve Gasoline (Eurosuper) + addition less than 100 mg / valve (1 g / 1000 g petrol)
