• Fast detection:
• Ratio between
knock sensor
and knock
threshold in
main knock
window > 1.50
– 2.50 [-]
• For time >=
540.0° CRK
• Or
• Ratio between
knock sensor
and noise level
in pre knock
window > 2.75
– 4.50 [-]
• For time >=
360.0° CRK
• Case 1:
• ratio between
filtered engine
roughness and
misfire detec‐
tion threshold
<= 0.41 – 0.59
[-]
• Or
• Case 2:
• Ratio between
normalized en‐
gine roughness
and misfire de‐
tection thresh‐
old <= n.a. [-]
• Or
• Case 3:
• Ratio between
filtered engine
roughness and
misfire detec‐
tion threshold
<= n.a. [-]
• Or
• Ratio between
normalized en‐
gine roughness
and misfire de‐
tection thresh‐
old <= n.a. [-]
