What is How often is oil changed in the gas engine??

Oil change for gas engines every 2,000 operating hours with special gas engine oil; oil pressure (3.5–5.0 bar) and oil temperature (75–90 °C) monitored daily — oil consumption over 0.8 g/kWh signals wear.

What the AI reads from these values

What the AI reads
  • Oil temperature (target range 75–90 °C) as an indicator for viscous stability
  • Oil pressure (3.5–5.0 bar) to check circulation integrity
  • Oil consumption (> 0.8 g/kWh) as an early indicator of wear on bearings or piston rings
  • Deviation of the cooling water temperature (reference: 83.4 °C) for detection of overheating in the system
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

Precise monitoring of oil parameters prevents costly engine damage and minimises unplanned downtime of the CHP unit. Adherence to the interval of 2,000 operating hours guarantees lubricity under load. Proactive monitoring of limit values reduces wear and optimises overall plant efficiency. electrical power (kW) · supplied gas power (kW) → — % elec. efficiency Calculation: electrical power ÷ gas power × 100
