Definitions
- the present invention relates to the use of imidazolium salts as additives for fuels, in particular as detergent additives for diesel fuels, especially for diesel fuels used in direct-injection diesel engines, in particular in common-rail injection systems, to be burned. Furthermore, the present invention relates to an additive concentrate as well as a fuel or fuel composition containing such imidazolium salts. Furthermore, the present invention relates to novel imidazolium salts and their use in industrial fluids.
- direct-injection diesel engines the fuel is injected through a multi-hole injection nozzle of the engine directly into the combustion chamber and finely distributed (nebulized) instead of being introduced into a pre- or swirl chamber as in the classic (chamber) diesel engine.
- the advantage of direct-injection diesel engines lies in their high performance for diesel engines and yet low consumption. In addition, these engines achieve a very high torque even at low speeds.
- the diesel fuel is pumped by a pump with pressures up to 2000 bar into a high-pressure line, the common rail.
- spur lines run to the various injectors, which inject the fuel directly into the combustion chamber.
- the full pressure is always applied to the common rail, which allows a multiple injection or a special injection form. In the other injection systems, however, only a smaller variation of the injection is possible.
- Injection in the common rail is essentially subdivided into three groups: (1) pre-injection, which substantially achieves softer combustion, so that hard combustion noise ("nailing") is reduced and engine running appears quiet; (2.) main injection, which is responsible in particular for a good torque curve; and (3.) post-injection, which provides in particular for a low NCv value.
- pre-injection which substantially achieves softer combustion, so that hard combustion noise ("nailing") is reduced and engine running appears quiet
- main injection which is responsible in particular for a good torque curve
- post-injection which provides in particular for a low NCv value.
- the fuel is not burned in the rule, but evaporated by residual heat in the cylinder.
- the resulting exhaust gas / fuel mixture is transported to the exhaust system, where the fuel in the presence of suitable catalysts acts as a reducing agent for the nitrogen oxides NO x .
- the pollutant emissions of the engine eg the emission of nitrogen oxides (NO x ), carbon monoxide (CO) and particulate matter (soot) can be positively influenced in the common-rail injection system.
- NO x nitrogen oxides
- CO carbon monoxide
- the international application WO 2012/004300 (1) describes acid-free quaternized nitrogen compounds as fuel additives which are obtained by addition of a compound containing at least one anhydride-reactive oxygen or nitrogen-containing group and additionally at least one quaternizable amino group to a polycarboxylic anhydride compound and subsequent quaternization with an epoxide in the absence of free acid.
- Polyamines having at least one primary or secondary amino group and at least one tertiary amino group are particularly suitable as compounds with an anhydride-reactive oxygen or nitrogen-containing group and additionally a quaternizable amino group.
- Particularly suitable polycarboxylic acid anhydrides are dicarboxylic acids such as succinic acid with a longer-chain hydrocarbyl substituent.
- Such a quaternized nitrogen compound is, for example, the reaction product of polyisobutenyl succinic anhydride obtained at 40 ° C with 3- (dimethylamino) propylamine, which is a polyisobutenylsuccinic acid hemiamide and which is then quaternized with styrene oxide in the absence of free acid at 70 ° C.
- acid-free quaternized nitrogen compounds are particularly suitable as fuel additive for reducing or preventing deposits in injection systems of direct-injection diesel engines, especially in common-rail injection systems, to reduce the fuel consumption of direct-injection diesel engines, especially diesel engines with common-rail injection systems, and / or to minimize the power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems.
- the international application PCT / EP201 1/071683 (2) describes polytetrahydrobenzoxazines and bistetrahydrobenzoxazines as fuel additives which are obtainable by successively adding in a first reaction step a C 1 to C 20 -alkylenediamine having two primary amino functions, eg 1, 2 Ethylenediamine, with a Cr to Ci2-aldehyde, z. B.
- the bis-tetrahydrobenzoxazine thus obtained is heated to a temperature of from 125 to 280 ° C. for at least 10 minutes.
- Such polytetrahydrobenzoxazines and bisty-hexane-benzoxazines are particularly suitable as fuel additives for reducing or preventing deposits in injection systems of direct-injection diesel engines, in particular in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, in particular diesel engines with common rail engines.
- variables R 1 and R 3 independently of one another are an organic radical having 1 to 3000 carbon atoms
- the variables R 2, R 4 and R 5, independently of one another denote hydrogen or an organic radical having 1 to 3000 carbon atoms
- X denotes an anion and n represents the number 1, 2 or 3, found as additives for fuels.
