What is valve clearance?

Insufficient valve clearance prevents the valves from closing completely (burning through), while excessive clearance causes noise and increased cylinder temperatures — inspection belongs to major service (typically every 8,000 operating hours).

What the AI reads from these values

What the AI reads
  • Measurement of the mechanical clearance to prevent valve burn-through due to incomplete closing
  • Monitoring of the cylinder temperature, as excessive clearance increases local heat generation
  • Detection of noise emissions indicating excessive valve clearance
  • Ensuring gas tightness to avoid compression losses in the CHP unit process
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

Correct adjustment prevents costly valve replacements and ensures the long-term availability of the CHP unit. Precise values minimise valve wear caused by thermal overload. This stabilises the operating temperature and significantly extends the service life of the components. electrical power (kW) · supplied gas power (kW) → — % electrical efficiency Calculation: electrical power ÷ gas power × 100
