Definitions
- the present invention relates to new uses of copolymers for removing and / or reducing deposits in the fuel system and / or injection system of direct-injection diesel and / or gasoline engines.
- the present invention relates to the use of certain copolymers as a fuel or lubricant additive; Process for the preparation of such additives, and additives and fuels additized therewith; in particular as a detergent additive; Use of these copolymers to reduce or prevent deposits in the fuel systems and in particular 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 to minimize the Power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, in particular for the operation of DISI engines.
- Background of the invention :
- direct-injection diesel engines the fuel is injected through a directly into the combustion chamber of the engine reaching multi-hole injection nozzle and finely distributed (atomized), instead of being introduced as in the classic (chamber) diesel engine in a vortex or vortex chamber.
- 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 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 in particular ensures a low NO x 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 in particular ensures a low NO x 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 such as the emission of nitrogen oxides (NO x ), carbon monoxide (CO) and in particular of particles (soot) can be positively influenced.
- NO x nitrogen oxides
- CO carbon monoxide
- particles particles
- deposits can form under certain conditions, for example when using biodiesel-containing fuels or fuels with metal impurities such as zinc compounds, copper compounds, lead compounds and other metal compounds, the injection behavior of the Negatively affect the fuel and thereby affect the performance of the engine, ie In particular, reduce the power, but in part also deteriorate the combustion.
- the formation of 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.
- I DI D internal diesel injector deposits
- injection system is understood to mean the part of the fuel system in motor vehicles from the fuel pump through the injector outlet.
- fuel system is understood to mean the components of motor vehicles that are in contact with the respective fuel, preferably the area from the tank up to and including the injector outlet.
- the compounds of the invention against deposits not only act in the injection system, but also in the rest of the fuel system, in particular against deposits in fuel filters and pumps.
- WO 201 1/146289 discloses nitrogen-free additives of a substituted hydrocarbon having at least two carboxyl groups in free or anhydride form for improving detergency in fuel systems.
- hydrocarbyl substituted succinic anhydrides and hydrolyzed forms thereof are disclosed, inter alia.

- copolymers have been shown to be effective in suppressing and / or eliminating the following deposits in diesel and gasoline engines:
- copolymers are characterized in particular by the fact that they act against a variety of deposits that affect the performance of modern diesel engines.
- the compounds according to the invention have an effect, for example, against loss of power, both caused by zinc input and also due to sodium introduction into the diesel fuel. In this case, deposits in the spray channels and the injector tip are essentially eliminated or avoided.

- a direct-injection diesel engine with common rail system from the manufacturer Peugeot was used in accordance with test methods CEC F-098-08.
- the fuel used was a commercial B7 diesel fuel according to EN 590 from Aral. To this was added in each case 1 wt ppm of sodium naphthenate and 20 wt ppm of dodecenylsuccinic acid to artificially induce the formation of deposits.

- the test was shortened to 8 hours, the CEC F-98 -08 process was carried out without the addition of Zn but with the addition of sodium naphthenate and dodecenylsuccinic acid. If significant deviations from exhaust gas temperatures were observed, the test was stopped before reaching the 8 hour mark to avoid engine damage. After the dirty-up run, the engine was allowed to cool and then restarted and idled for 10 minutes. During these 10 minutes the engine was warmed up. The exhaust gas temperature The temperature of each cylinder was recorded. The smaller the differences between the detected exhaust gas temperatures, the lower the amount of IDID formed.
- the compounds according to the present invention are very efficient for prevention / removal in direct injection engines, as seen on the Peugeot DW10 engine in a test similar to CEC F-98-08, but with 1 wt ppm Na in the form of sodium naph - Thenat and 20 wt ppm dodecenylsuccinic acid.
