153226 – HI Knock Integrator A6
Yellow alarm. Initiated by SAM.
Cause
Corrective action
Readjustment of ignition timing
beyond a limit value because
knocking was detected in this
cylinder.
1. Check emission values.
2. Check ignition timing (→ Page 154).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
