Al,

So, how would you arrange a "limp home" mode that avoided a low volts
problem, with electronic fuel injectors?

If you go to mechanical injectors, you lose the advantages inherent in
the electronic ones.


Ah, thank you!

Of course, as Bertie puts it, one could theoretically build alternative
injectors in, I guess. One could also plate the engine with gold. But, as you
say, an engine with electronic fuel injectors is an engine with ELECTRONIC
fuel injectors. The basis for the engine is a mass-production car engine.
That's what makes (may make) the engine viable in the market. And I still
fail to see how "mechanical" would somehow inherently be better or more
relaible than "electric". In fact, a common rail diesel has a much simpler
mechanical design than one with mechanical injectors - it is much less prone
to failure in that respect.

Interestingly, the SMA diesel is of the old style, with mechanical injectors.
It also has a mechanical emergency throttle. It also has gained zero traction
in the market, in large part due to its high price.
