Definitions

  • the invention relates to a lubrication system for a piston-cylinder unit according to the preamble of claim 1.
  • the invention further relates to an internal combustion engine, in particular a large engine with a piston-cylinder unit with a lubrication system.
  • Large engines especially in the design as large diesel engines, which may be configured as two-stroke or four-stroke internal combustion engines, are often used as drive units for ships or in stationary operation, e.g. used to drive large generators for generating electrical energy.
  • the large engines usually run for long periods in continuous operation, which places high demands on the reliability and availability. Therefore, for the operator in particular long maintenance intervals, low wear and an economical handling of the operating materials are central criteria.
  • the piston slides along the surface of the wall of the cylinder serving as a running surface, which is usually designed in the form of a cylinder liner, which is also referred to as a cylinder liner.
  • a cylinder or piston lubrication is provided.
  • the piston must slide as smoothly 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 ensure efficient conversion of energy released during the combustion process into mechanical work.
  • a lubricant usually in the form of a lubricating oil
  • a lubricating oil is used to neutralize aggressive combustion products and to prevent corrosion. Because of these many requirements, very high quality and expensive substances are often used as lubricants.
  • Lubricant consumption is the amount of lubricant understood that is no longer available for the actual lubrication task, ie by the lubrication process is consumed, so lost. This loss may be due to the fact that the lubricant is taken up as droplets in the fuel gas or distributed as a lubricant film along the cylinder inner wall. This lubricant can therefore enter the combustion chamber in gaseous form or liquid form, ignite there and be burned, an effect which is undesirable in itself, because it can lead to misfires or deposits in the cylinder interior.
  • a proven lubrication method is the so-called internal lubrication, in which the lubricant is conveyed through the interior of the piston and then applied via one or more lubrication points, which are provided on the surface of the piston from the piston inner to the piston or on the cylinder surface.
  • Such a method is used, for example, in EP-A-0 903 473 disclosed.
  • an oil collection ring may be provided, as he, for example, from the EP2133520 A1 or from the EP 1 936 245 A1 is known. That is, by means of an oil collection ring can be avoided that lubricant enters the combustion chamber.
  • the sliding surface of the piston in the cylinder interior and lubricant can also be supplied via the cylinder liner itself and are also recorded in the cylinder liner itself in recesses, as for example in the EP 20 50 946 A1 are disclosed.
  • the cylinder lubrication of two-stroke marine diesel engines is carried out by the metered injection of lubricant, the current standard lubrication systems inject only about every tenth revolution due to the constant-volume pump, which is unfavorable for the distribution of the lubricant.
  • the relatively long lines between the pump and injector reduce the dynamics of the system, that is, the amount of time that a metering pulse takes to cover the distance from the pump to the lubricant injector is too long to provide precise control over the injection timing Allow pump.
  • the connecting lines losses due to pipe friction increase, so that by the elasticity of the lubricant by its compressibility in the connecting lines no pulse more detectable at the entrance of the lubricant injection valve.
  • the WO0235068 A1 shows a fluid agent actuated lubricant injection element.
  • a sufficiently high fluid pressure must be available.
  • This fluid fluid pressure is generated according to this embodiment with a mounted on the lubricant injection pump, which is driven by a separate motor. According to this solution, therefore, one pump and one motor are required for each lubricant injection element. Therefore, if a plurality of lubricant injection elements are provided, this solution results in increased maintenance and increased investment costs. Therefore, this solution may be unsuitable for use in multi-cylinder engines, especially in large marine engines.
  • the maintenance effort must be as low as possible, since the engines must run in continuous operation over the entire journey time of the ship. That is, for redundancy reasons, a plurality of such fluid agent actuated lubricant insert elements would have to be kept redundant in stock. On the other hand, the investment costs should be kept as low as possible.
  • the WO2011116768 A1 shows such a common rail system for the injection of lubricant in a plurality of cylinders of an internal combustion engine.
  • the problem of connecting lines described earlier is solved such that the metering of the lubricant takes place directly in the lubricant element via solenoid-controlled valves.
  • the supply of lubricant can be controlled very accurately, both the time of supply of lubricant to the cylinder, and thus the duration of the supply of lubricant, that is, the amount of lubricant to be supplied to the lubrication point.
  • the magnet-controlled valves to be used for this purpose that the supply of lubricant can be initiated by opening the connection to the lubricant nozzle, but also that the supply of lubricant can be interrupted again.
  • the interruption of the lubricant supply may take a different amount of time until the closing pressure is reached, that is to say the lubricant volume which reaches the lubricating point is greater than that provided by the regulation. It is of course possible to set a pressure-dependent switching behavior of the solenoid-controlled valve, but this means an increased control effort. Of course, possible to set a pressure-dependent switching behavior of the solenoid-controlled valve, but this means an increased control effort.

  • the outlet opening can be closed by a ball check valve, whereby the ball check valve can be moved by means of the pressure of the lubricant in such a way that the outlet opening can be released for the delivery of lubricant.
