Prevention is the best action, and that means keeping the Brake Mean Effective Pressures
(B.M.E.P.) within engine limitations. The charts further on in this Section have limiting
values for all power settings.
To prevent Pre-Ignition and Detonation from occurring
A Use correct mixture setting
B Do not over boost
C Maintain correct engine operating temperatures
If either condition is suspected:
A Use a richer mixture setting
B Reduce boost and/or power
C Increase RPM
07 USE OF ENGINE CONTROLS
When increasing the power RPM is to be increased before the Manifold Pressure is
increased.
When decreasing power reduce the manifold pressure before RPM
Ensure that the mixture control is at Auto Rich prior to increase power
After the power has been reduced to cruise move the Mixture to Auto Lean after a period
of time has elapsed to adjust the cylinder head temperatures to settle at or below 200degC
