Make sure your 2-stroke engines are ready for the 2020 low-S challenges

World class cylinder condition monitoring and reconditioning by Chris-Marine

Go to:

Why prioritize cylinder condition monitoring and reconditioning?

  • To increase cyliner liner lifetime
  • To restore engine performance
  • To avoid running-in problems
  • To ensure accurate lube oil consumption
  • The consequences of ignoring monitoring and reconditioning are way too costly

Condition Monitoring

CHRIS-MARINE®

LDM

Liner diameter measuring instrument

Measures cylinder wear / remaining life time, ovality and clover leafing.
Liner time scale: ~/1000 Rh.
Measurment time: ~1 h/liner.
CHRIS-MARINE®

CTM

Coating thickness measurment tool

Measures the wear rate / remaining life time for coated piston rings.
Liner time scale: ~1000 Rh.
Measurment time: ~15 mins/liner.
CHRIS-MARINE®

LCC

Liner condition camera

Scans / documents the condition of cylinder liner surface, exhaust valve, piston rings and piston crown.
Liner time scale: ~100 Rh.
Measurement time: ~15 mins/liner.
CHRIS-MARINE®

RAM

Replica analysis & microscopy

Takes an imprint of the liner that is later analysed in microscope in Chris-Marine's laboratory.
Liner time scale: ~100 Rh.
Measurement time: ~15 mins/liner.

Reconditioning

HON 2A

HON 2A

Fully automatic electric honing and deglazing machine for restoration of slow speed engine cylinder liner geometry and surface structure. For workshop and in-situ use.

  • For liners with 500 to 1000 mm bore
  • Rectifies the shape of the liner
  • Removes scuffing marks and restores surface cross pattern
  • Fully automatic operation
  • Powerful electric driving unit and hoist
  • Adjustable stone pressure
  • Pre-assembled rig
  • System for continuous supply of honing liquid
  • Automatic stroke control
  • Ability to specify exact cross pattern angle
  • Cannot go beyond set turning points
  • Speed and stroke length adjusted during operation
  • Electrically driven

VKS - Wear Edge Milling Machine

VKS

The Chris-Marine wear-edge grinder, VKS, is available as multi-bore version (for workshop use) and single-bore version (for on-board use).

WGM - Wavecut Grinding Machine

WGM

For MAN cylinder liners, wave-cut grinding is sometimes used after honing. Wave-cut is a spiral pattern in the liner surface that acts as an oil reservoir and oil distributor in the liner surface.
