What is How do I identify turbocharger wear??

Symptoms: falling boost pressure below setpoint, increased oil consumption, smoky exhaust gases and power loss; the boost pressure (setpoint range 3.5–4.5 bar) is the most direct indicator — early replacement prevents engine damage due to lack of oil in the turbo bearing.

What the AI reads from these values

What the AI reads
  • Deviation of the boost pressure from the setpoint (typically 3.5–4.5 bar) as a primary indicator for compression loss.
  • Increase in specific oil consumption in the turbocharger lubrication area.
  • Increased exhaust gas temperature and smoke formation, indicating incomplete combustion.
  • Degradation of the boost pressure curve during load changes as an early indicator of bearing damage.
Scenario

Monitored: continuous

The scenario: a gradual drop in oil pressure or a drifting temperature remains below the alarm threshold until the emergency shutdown occurs — at the worst possible moment. The AI: detects the deviation from normal operation early and reports it before the protection trips. It identifies the trend before the limit value is reached.

Why this matters

Early detection of boost pressure deviations prevents costly emergency shutdowns and protects the turbo bearings from irreversible wear. A stable boost pressure guarantees the target efficiency of the CHP unit. Monitoring significantly reduces the risk of engine damage due to thermal overload. electrical power (kW) · supplied gas power (kW) → — % elec. efficiency Calculation: electrical power ÷ gas power × 100
