Definitions

  • the invention relates to a large diesel engine according to the preamble of the independent claim.

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.
  • lubrication systems used in large diesel engines deliver the lubricant, usually a lubricating oil, through the wall of the cylinder to the tread or directly into the piston ring package of the piston so that the piston rings distribute the lubricant on the tread during their movement.

  • a lubricating oil pump per cylinder For the supply of the individual lubrication points usually a lubricating oil pump per cylinder is used, which supplies all lubrication points of this cylinder with lubricant. Due to the design, this lubricating oil pump may be a few meters away from the respective cylinder or from the respective lubrication points.
