Walter,
I'm relatively new to this site and while I do not
personally know you, I am impressed with your core engine knowledge. I am
an ex-General Motors Engine Development engineer and I would guess you have
significant engine dynamometer development time. Question....with the IO
or TSIO 550 engines or for that matter any aircraft engine....do you have to
worry about pre-ignition when running very low RPM's and WOT? I have seen
engines go into pre-ignition for less than 3 seconds and the result was a hole
thru the piston.
Also "70dF
LOP".....is this 70 deg F lean of LBT (lean best torque)?
In automotive engines, low RPM, WOT and lean of
best torque would almost guarantee you detonation and sometimes
pre-ignition. Are these engine's characteristics similar?
