Piston rod stuffing box - optimal engine operation

Piston Rod Stuffing box


The unique feature of a slow speed two stroke engine is the sealing between the dirty combustion part and the clean crankcase. The heart of this division is the piston rod stuffing box.

The combination of scraper and sealing rings and lamella scraper rings solves three vital tasks:

  • Impurities from the scavenging air space are prevented from entering the crank case housing.
  • A pressure-tight seal is created between the scavenging air space and the crank case.
  • System oil waste is reduced to a minimum.
