153221 – HI Knock Integrator A1
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 149).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).

beyond a limit value because
knocking was detected in this
cylinder.
1. Check emission values.
2. Check ignition timing (→ Page 149).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
153223 – HI Knock Integrator A3
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 149).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
