Definitions
- Quaternized nitrogen compounds and their use as additives in fuels and lubricants are used as additives in fuels and lubricants.
- the present invention relates to novel quaternized nitrogen compounds, their preparation and use as a fuel and lubricant additive, in particular as a detergent additive additive packages containing these compounds; as well as with it additized fuels and lubricants. Furthermore, the present invention relates to the use of these quaternized nitrogen compounds as a fuel additive for reducing or preventing deposits in the injection systems of direct injection diesel engines, especially in common rail injection systems, to reduce the fuel consumption of direct injection diesel engines, especially common rail diesel engines Injection systems, and to minimize the power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems.
- direct-injection diesel engines the fuel is injected through a multi-hole injection nozzle directly into the combustion chamber of the engine and finely distributed (atomized) instead of being introduced into a vortex 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 from 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 essentially achieves softer combustion, so that hard combustion noises ("nails") are 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 NO x value.
- pre-injection which essentially achieves softer combustion, so that hard combustion noises ("nails") are 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 NO x value.
- the fuel is not burned in the rule, but evaporated by residual heat in the cylinder.
- the exhaust gas / fuel mixture formed during this process is transported to the exhaust gas system, where the fuel acts as a reducing agent for the nitrogen oxides NO x in the presence of suitable catalysts.
- 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
- particulate matter particulate matter
- deposits is further enhanced by structural developments of the injectors, in particular by the change in the geometry of the nozzles (narrower, conical openings with rounded outlet). For a permanently optimal functioning of engine and injectors such deposits must be prevented or reduced in the nozzle openings by suitable fuel additives
