Challenge

Extremely fast ring consumption

  • Rings provided by OEM failed after less than 100 h
  • Major damages to pistons and liners due to inadequate protection system
  • Alternate material from OEM’s competitor lasted for 1500 h

Solution

  • New lubrication system
  • Improved cylinder cooling system
  • Stronger material (PEEK) with optimized dimensions
  • New piston design
