What is a knock sensor?

Detects abnormal combustion pressure peaks (knocking due to a mixture that is too rich, excessive charge air temperature or incorrect ignition timing) and thus protects the piston and cylinder from damage.

What the AI reads from these values

What the AI reads
  • Detection of abnormal combustion pressure peaks due to insufficiently controlled mixture composition.
  • Identification of overheated charge air, which leads to unstable combustion processes.
  • Monitoring of the ignition timing to prevent detonations during high load changes.
  • Early warning of mechanical damage to pistons and cylinders caused by uncontrolled pressure waves.
Scenario

Monitoring: 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 system triggers. It identifies the trend before the limit value is reached.

Why this matters

Preventive detection of knock signals prevents irreversible material fatigue and costly downtime due to engine damage. Precise monitoring enables safe operation in the limit range of the load curve. This significantly extends the service life of the cylinder components. electrical power (kW) · supplied gas power (kW) → — % electrical efficiency Calculation: electrical power ÷ gas power × 100
