Definitions

  • the invention relates to an engine lubricating oil for diesel engines equipped with a particle filter in the exhaust gas flow and a method for operating a diesel engine with a particle filter system downstream of the engine in the exhaust gas line, in which the temperature for the combustion of soot particles deposited on the filter system is reduced due to the presence of catalytically active substances is.
  • EP-0 052 478-B1 is an operating method for a diesel engine, in which one consecutively carries out the combustion of a diesel fuel in the engine, passes the engine exhaust through a separator and thereby removes soot particles from it and heats the separator to a sufficiently high temperature to cause oxidation of the soot particles, wherein particles of a catalyst which lowers the oxidation temperature of the soot are introduced into the separator with the exhaust gases.
  • Suitable catalyst substances are lead or copper or manganese or their mixture in elemental form or preferably in the form of chemical compounds, the catalyst substances preferably being added to the diesel fuel.
  • Effective diesel particle filter systems have therefore been developed by technology, in particular so-called monolithic ceramic filters, with honeycomb-like ceramic bodies that contain a large number of channels that are mutually closed at the ends, or ceramic wound filters made of circularly arranged, perforated steel support tubes with several layers of a roughened yarn Filters made of ceramic fibers are used (cf. ATV 1 / 2-88, pages 14 to 17).
  • the exhaust gas from the diesel engines flows through the labyrinth passages of the monolithic ceramic filters, the ceramic walls forming the honeycomb passages, in turn, being porous and permitting the passage of the exhaust gas cleaned of particles, or the exhaust gas particles being retained by the filaments of the ceramic yarns when flowing through the so-called wound filters.
  • the object of the invention is to ensure economical operation of a diesel engine with a particle filter system downstream of the engine in the exhaust pipe by providing new engine lubricating oils for diesel engines and to specify a corresponding method for operating a diesel engine in which such engine lubricating oils are used.
  • the temperatures which are sufficient for the regeneration of the diesel particle filter by burning should be so low that regeneration occurs as often as possible.
  • the filter In the case of unfavorable operating conditions of the diesel engine, for example a power output that lead to only low exhaust gas temperatures, the filter is so far covered with particles that the exhaust gas back pressure reaches impermissibly high values.
  • there is a risk that a filter that is too heavily loaded will be thermally loaded too much during regeneration due to burning and will melt locally, which can lead to a deterioration in the function of the filter.
  • the present invention resides in the fact that an engine lubricating oil for diesel engines equipped with a particle filter system with a catalytically active content of an iron compound is proposed.
  • the invention is based on the knowledge that a certain proportion of the lubricating oil also participates in engine combustion.
  • the catalytically active substance is also supplied in sufficient quantity to the diesel particle filter system with the hot engine exhaust gas when the engine is operated as intended, where a further quantitative reaction of the particulate organic components initially retained by the filter is important.
  • the purpose of the invention is also promoted by the catalytically favored conversion of the particulate organic constituents with the residual oxygen present in the exhaust gas, which takes place before it is deposited on the filter.
  • the content of catalytically active iron compounds in the exhaust gas stream sufficient for the diesel particle filter regeneration with weight ratios of 5 to 20,000, preferably 50 to 10,000, ppm of the iron compound, in particular the organometallic iron compound, based on the proposed additization of the lubricating oil Lubricating oil quantity, find use.
  • Ferrocene bis ( ⁇ -cyclopentadienyl) iron
  • iron compounds with a complex salt of an organic acid in which the ratio of the number of equivalents of the organic acid to the number of iron atoms is 3 or less, for example iron tallate are particularly suitable.
  • the aforementioned compounds are because of their catalytic activity and their good solubility and lubricating oil compatibility are particularly suitable as additives.
  • the proposed additization of the lubricating oil offers an advantageous alternative to introducing the catalytically active substances by additizing the diesel fuel or to a separate additional metering device.
  • the effect according to the invention was verified in a comparative test program with a stationary vehicle diesel engine, manufactured by Ford 2.5 l direct injection.
  • the engine is equipped with a diesel particulate filter system made of a ceramic monolith catalyst, manufactured by Corning, installed in the exhaust line downstream of the engine.
  • the engine was operated with a commercially available diesel engine lubricating oil of viscosity class 15W-40. With a constant power output of 18 kW, an exhaust gas back pressure rising from 100 mbar to approximately 350 mbar built up over a running time of 2 1/2 hours.
  • the engine lubricating oils according to the invention are added by direct dissolution, for example up to concentrations of 10,000 ppm, or else preparation of concentrated solutions in a suitable lubricating oil component. Additives in concentrations of 5 to 20,000 ppm, preferably 50 to 10,000 ppm, based on the engine lubricating oil (weight ratio), are preferred.
  • FIG. 1 shows schematically the experimental arrangement used for the installation of the diesel particle filter in the exhaust pipe of the diesel engine and the pressure measuring point.
