WingFlaps,

I agree, there is no fundamental need for the FADEC in a diesel.


You need to let go of what you Americans consider to be a "diesel".
That's good for trucks and boats, but not for efficient small cars -
and airplanes.

We're talking modern, common-rail diesels which get their efficiency
and attractivity through complete electronic control.

FWIW, Thielert's two main developments (cost- and engineeringwise) are

1. the fuel pump (which has nothing to do with a gasoline pump), which
is self-lubricating with car diesel, but must be jet fuel compatible -
and jet fuel lubricates less well.

2. The FADEC, which, Bertie, has nothing to do with the car's engine
control, has dual redundancy and also proper electrical redundancy if
installed right (it wasn't in the DA-42, IMHO).

Thielert starts with a Mercedes car engine and exchanges 150 parts
before that engine becomes a Thielert.
