Surely the point of using a compression ignition engine is that it runs without external electric power. I understand the need for some external monitoring etc but why would you then design the engine so it needs electric power to continue functioning?
Could not the failure mode be a simple standard functioning?
Years ago I thought the VW aluminum diesel engines would be a suitable base for an aero engine (The 10 cylinder) but any time I suggested it I was shouted down as "That would never work" or "They'd obviously be too heavy." Is the twelve cylinder a custom block or standard from the big saloons?
If that is privileged info I'd understand!
