Definitions

  • the invention relates to a method for lubricating a large diesel engine and a large diesel engine according to the preamble of the independent claim of the respective category.
  • the piston slides along the inner wall of the cylinder serving as a running surface, which is usually configured in the form of a cylinder liner.
  • the piston must slide as easily as possible, that is unhindered, in the cylinder, on the other hand, the piston must seal the combustion chamber in the cylinder as well as possible in order to achieve an efficient To convert the energy released during the combustion process into mechanical work.
  • a lubricating oil is usually introduced into the cylinder in order to achieve good running properties of the piston and to minimize the wear of the cylinder wall, the piston and the piston rings. Furthermore, the lubricating oil is used to neutralize aggressive combustion products and to prevent corrosion. Due to these numerous requirements, lubricating oils are often used very high quality and expensive substances.
  • One lubrication system includes the so-called system oil or system lubricant which is commonly used to lubricate all bearings such as crankshaft main bearings, crosshead bearings, crossheads, etc., and often also for (internal) cooling of the piston.
  • the other lubricant system includes a special cylinder oil or cylinder lubricant commonly used for lubrication of the piston, piston rings, and tread.
  • the cylinder lubricant is a pure all-loss product, i. After it has been applied to the tread or the piston and contaminated in the combustion chamber, the remains are collected and disposed of.
  • the system lubricant is not a consumable product, i. H. it is cleaned and then returned to the lubricant source.
  • a method for lubricating a large diesel engine which has at least one cylinder provided in a cylinder block with a piston which can be moved back and forth in the cylinder along a running surface, which piston delimits a combustion chamber and is connected to a crankshaft provided in a crankcase, wherein for lubricating the piston, a lubricant from a lubricant source is introduced into the cylinder, which by the in Combustion chamber occurring combustion process is contaminated. The contaminated lubricant is removed from the cylinder before it can get into the crankcase and is then fed to a cleaning device and cleaned there.
  • the measure to remove the contaminated lubricant from the cylinder and clean before it can get into the crankcase has in the lubrication of the two-stroke large diesel engine with the result that the coming out of the combustion chamber lubricating oil no longer - as it is state of the art - Is regarded as a waste product, but is reusable by cleaning. This is a big advantage in economic terms.
  • the inventive method results in that the highly contaminated lubricant is removed from the cylinder before it can mix with the relatively clean lubricant at the bottom of the crankcase.
  • the contaminated lubricant is removed at a location intermediate the lower dead center of the last piston ring and the boundary between the cylinder block and the crankcase.
  • the last piston ring is meant the one which is farthest from the combustion chamber.
  • This last piston ring can also be configured as an oil scraper ring. This measure can namely ensure that as much as possible from the combustion chamber or from the tread derived lubricant is collected, with mixing with the oil in the crankcase is efficiently avoided.
  • An advantageous measure is that the purified lubricant is supplied to the lubricant source, so that the lubricant is guided in a lubricant circuit.
  • the lubricant used for the piston or cylinder lubrication is no longer consumables that must be disposed of after use, but can be fed back to the lubricant source or other points of the lubricant circuit after cleaning.
  • the lubrication rate or amount of lubricant applied to the tread or piston per time can be increased to achieve even better lubrication.
  • the total lubricant requirement is significantly reduced by the return of the cleaned lubricant, which is a considerable advantage in terms of economy.
  • the cleaning of the highly contaminated lubricant leads to a slower aging of the total amount of lubricant, the change or refill intervals for the lubricant can be significantly extended and there is less lubricant than waste for disposal
