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.

  • 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.
Honing App

Honing App

Honing App to enhance quality, save time and document honing results.
