USE OF AMINES AND/OR MANNICH ADDUCTS IN FUEL AND LUBRICANT COMPOSITIONS FOR DIRECT INJECTION SPARK IGNITION ENGINES

Принадлежит: BASF SE

The present invention relates to the use of amines and/or Mannich adducts as detergents and/or dispersants in fuel and lubricant compositions for direct-injection gasoline engines. The invention further relates to fuel and lubricant compositions which comprise at least one such Mannich adduct, and also a bisaminoalkylated Mannich adduct. 218-. (canceled) The present invention relates to the use of amines and/or Mannich adducts as detergents and/or dispersants in fuel and lubricant compositions for direct-injection gasoline engines. The invention further relates to fuel and lubricant compositions which comprise at least one such Mannich adduct, and also a bisaminoalkylated Mannich adduct.Direct-injection gasoline engines are becoming increasingly important, since, especially in the lean range, i.e. at a lambda value of about 1 or greater, they enable better fuel utilization and a simultaneous increase in the engine output. This is accompanied by reduced carbon dioxide emission in comparison to conventional gasoline engines.The injection nozzles in direct-injection gasoline engines are disposed in the combustion chamber and are therefore exposed to extreme conditions. Under these conditions, intense decomposition and oxidation of the fuel takes place and an increased amount of deposits forms. Deposition problems affect mainly the injection nozzles, but also the inlet valves and the entire combustion chamber. Deposits on the injection nozzles restrict the fuel feed and change the injection behavior. A slightly reduced fuel feed can be compensated by appropriate electronic control; stronger feed restriction and change in the injection behavior can no longer be counteracted. However, for optimum fuel utilization and performance increase, impeccable injection behavior is essential. Therefore, the formation of deposits is to be avoided to a very substantial extent. In contrast to conventional engines in which relatively rich mixtures cause deposits, it is especially lean ...

A fuel oil composition containing: the fuel oil flow improver according to claim 1 , and fuel oil claim 1 , wherein the fuel oil composition contains 0.0005 to 1 parts by mass of the fuel oil flow improver in relation to 100 parts by mass of the fuel oil. 1. Field of the InventionThe present invention relates to a fuel oil flow improver and a fuel oil composition. More specifically, the present invention relates to a fuel oil flow improver which can sufficiently reduce the plugging point or the pour point of fuel oil, which has excellent dispersibility of a wax precipitated from the fuel oil to which the fuel oil flow improver is added, and also relates to a fuel oil composition containing the fuel oil flow improver.2. Description of the Related ArtFuel oils such as light diesel oil and heavy oil A contain a wax which is a long chain n-paraffin, and when the oil temperature decreases, such as in winter, problems occur such as the wax precipitating and plugging the filters in the fuel oil line, or congealing such that fluidity is lost, blocking the line. The temperature at which filter described above is plugged is referred to as the cold filter plugging point (CFPP), and the temperature at which fluidity is lost is referred to as the pour point (PP). Normally, a flow improver is used during the winter in order to improve the plugging point and the pour point.In addition, in fuel oils such as light diesel oil or heavy oil A, a problem also arises in which the wax precipitates within the fuel tank, and the precipitated wax settles on the base of the tank to form a thick, dense wax layer. It is known that when such a problem occurs, the ability of the engine to start is degraded remarkably, and a wax dispersibility modifier is used in ...
