And these potentialities for catastrophic failure should all have been diagnosed in advance of their exposure to operating conditions.
Lastly, there is the issue as to what will become of even oscilloscope analysis of the high voltage component of ignition system functioning.
Apparently, contemporary operating companies have come to the point of view that ignition analysis is unnecessary.
If this were not the case, why would the operators allow the engine manufacturers to supply them engines that prevent analysis of the secondary side of the ignition system. Since the oil and gas industry would be the largest market for this equipment, what does it say about the influence of engine analysis when engine operating companies obstruct them from doing it? And prevent them from doing it by design?
All of these engines are high speed, four strokes that drive separable compressors. All we can say is that when an operator of such equipment requests our help, we are prevented from being as thorough as we would like to be because the ignition coils are mounted directly to the cylinder head/valve cover, denying all diagnostic tools access to the secondary side of the ignition circuit when the engine is operating.
I would like to recommend that engine operating companies with future engine purchasing plans strongly consider specifying ignition arrangements to engine manufacturers that will offer the operator the means to fully analyze the secondary side of the ignition circuit. I would like to think that this would not be an impossibility.
