What are TA-Luft limit values?

TA Luft 2021 defines limit values for gas engines for NOx (650 mg/m³), CO and formaldehyde; exceedances are reportable and can lead to operational prohibitions — Lambda control and catalyst maintenance ensure compliance.

What the AI reads from these values

What the AI reads
  • Current NOx value compared to the limit value of 650 mg/m³
  • Deviation rate of the lambda control to ensure combustion efficiency
  • Trend analysis of the CO content as an indicator for catalyst activity
  • Early warning upon approaching the limit value to avoid operational prohibitions
Scenario

Monitored: continuous

The scenario: an emission value creeps slowly upwards, is only noticed during the official measurement, in the worst case leading to operating restrictions. The AI: detects the trend towards the limit value early and reports a need for action before the measurement occurs. It identifies the trend before the limit value is breached.

Why this matters

Continuous monitoring of the TA-Luft parameters ensures legal operating permission and prevents costly shutdowns. Precise monitoring enables timely maintenance intervals for the catalyst. This stabilises process management and guarantees compliance with statutory requirements.
