Guide for judging condition of relevant piston-running components (liners, pistons and piston rings) Version 2.1
Year: 2014 Language: english Author: Wärtsilä Genre: Guide Format: PDF Quality: eBook Pages count: 32 Description: This booklet shall serve as a guide for judging the condition of relevant components (liners, pistons and piston rings) for the condition-based maintenance during piston and liner overhauls of engines with latest piston-running standard with full CC (chromium ceramic) piston ring packages or CC top ring and lower RC (running-in coating) rings for smaller bores. Actual wear rates strongly depend on operational factors, such as fuel oil in use, engine load profile, ambient conditions etc. Especially with today’s slow steaming, engines may suffer from cold corrosion resulting in an increased wear on cylinder liners and piston rings, considerably reducing the TBO (time between overhauls). With this guide the overhauls can be planned, taking the operational conditions into account. On the other hand, for engines running under moderate operation conditions, piston overhauls can be extended, and piston TBO beyond 30’000 hours is achievable.

Description: This booklet shall serve as a guide for judging the
condition of relevant components (liners, pistons
and piston rings) for the condition-based
maintenance during piston and liner overhauls of
engines with latest piston-running standard with full
CC (chromium ceramic) piston ring packages or CC
top ring and lower RC (running-in coating) rings for
smaller bores.
Actual wear rates strongly depend on operational
factors, such as fuel oil in use, engine load profile,
ambient conditions etc.
Especially with today’s slow steaming, engines may
suffer from cold corrosion resulting in an increased wear
on cylinder liners and piston rings, considerably
reducing the TBO (time between overhauls). With this
guide the overhauls can be planned, taking the
operational conditions into account.
On the other hand, for engines running under moderate
operation conditions, piston overhauls can be extended,
and piston TBO beyond 30’000 hours is achievable.
