Cylinder lubrication systems

SKF cylinder lubrication systems for two-stroke engines operate load-dependently

In two-stroke engines, lubricant feed to the respective lubrication point (quill) is synchronized to piston positioning either mechanically (System CLU3) or electro-hydraulically (System CLU4).

Using this lubrication system can reduce the amount of lubricant needed by up to 30%. At the same time, reduction of emission values causes less harm to the environment.

Benefits:
  • More compact and economical design
  • Actual recommended cylinder lubrication technology for engine new builds
  • The engine maker specifies more frequent lube pulses with smaller dosing quantities
  • This concept allows a further reduction of the specific oil feed rate
  • Quick return of investment (ROI)
Advantages of the SKF cylinder lubrication system (CLU4)
  • Adaptable for all 2-stroke crosshead engines with performance range from 600 to 7000 kW/cylinder each with 3 to 12 quills
  • Servicing during operation (redundancy not a requirement)
  • Already available for Common Rail Technology
  • Simple, compact system design without the use of heating or additional equipment such as oil tank or fill level switch
  • Mechanically set metering volumes and integrated lock valve functions prevent improper system operation
  • Low installation costs
  • Automated determination of the optimum metering time in each case using electronic control and oil consumption measurement for each engine or individual cylinder
