What is What do the exhaust gas temperatures reveal??

What do the exhaust gas temperatures reveal?? Normal cylinder exhaust temperatures are between 480–560 °C with a max. 30 °C spread; a single significantly elevated cylinder indicates misfires or a defective spark plug, a reduced temperature indicates load change problems.

What the AI reads from these values

What the AI reads
  • Deviation of the cylinder spread (max. 30 °C) as an indicator for uneven load distribution
  • Increased individual cylinder temperature as an early warning for misfires or defective spark plugs
  • Significantly reduced temperature as an indication of load change problems in the intake tract
  • Trend analysis of the temperature downstream of the catalyst to check the exhaust gas aftertreatment
Scenario

Monitored: continuous

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

Why this matters

Early detection of ignition faults reduces the risk of failure and prevents thermal overloading of the cylinder heads. The identification of load change problems enables targeted maintenance intervals for the injection system. A stable temperature curve guarantees the service life of the catalyst and optimises the efficiency.
