Engineering · Diesel — Wear
Excessive cylinder liner wear in a diesel engine is commonly caused by:
- AOver-cooling and acidic corrosion from sulfur in the fuel✓ Correct
- BRunning the engine only at full load
- CUsing too high a cetane fuel
- DExcess scavenge air pressure
Explanation
If liner surface temperature drops below the acid dew point, sulfuric acid condenses and causes cold corrosion. Abrasive wear from dirt and inadequate cylinder oil also contribute.
