What is Gas mixer & throttle valve?

Mixes biogas with intake air; gas mixer position (0–100 %) and throttle valve position jointly determine lambda and engine power — full load position: both near 100 %.

What the AI reads from these values

What the AI reads
  • Gas mixer position (0–100 %): indicator for the biogas proportion in the combustion chamber.
  • Throttle valve position: determines the intake air quantity to adjust the air-fuel ratio.
  • Lambda value: derived value from both positions to prevent over-fueling or starving.
  • Full load state: correlation of both values near 100 % as an indicator for the maximum utilization of the CHP unit.
Scenario

Monitored: continuous

The scenario: if the methane content decreases slowly, the engine begins to knock without an alarm occurring, leading to power reduction and wear. The AI: detects the quality trend early and reports it before the knocking causes damage. It identifies the trend before the limit value is reached.

Why this matters

Precise monitoring of the setpoints prevents engine damage caused by incorrect lambda and optimises efficiency. The correlation between gas mixer and throttle valve enables proactive fault diagnosis in cases of unstable gas qualities. This secures the service life of the engine and stabilises the electrical feed power. Gas volume (m³/h) · methane content (%) → — kWh/h calculation path: gas volume × methane content × 9.97 kWh/m³ (methane calorific value)
