Engineering · Lubrication — Oil Analysis
Routine lube-oil analysis that detects increasing iron and chromium particles most likely indicates wear of:
- APiston rings/cylinder liners✓ Correct
- BThe fuel injectors
- CThe turbocharger turbine
- DThe fuel transfer pump
Explanation
Spectrographic oil analysis correlates wear metals to components: iron/chromium points to rings, liners, and shafts; copper/lead/tin to bearings; silicon to dirt ingress. Trends, not single readings, drive maintenance decisions.
