Engines where the fuel detonates are soon called junk.


Pedant point: Diesel and Gasoline engines fall into this category. :-)

Or did you mean "detonates in the fuel tank"? :-)

It is relatively easy to keep gas under control.

It is rather hard to keep ether from detonation and pre-ignition.

Also, the smog components of engine exhaust are not a factor of the
fuel. The come from using air which contains nitrogen as the oxidizer.

The higher the combustion temperature, the more smog components you
get.

I'm assuming you are talking about orinary ether as used as an engine
starting aid.


I'm not the one that brought up ether (presumably, that's
Glazier's idea), which is actually a class of organic
compounds (presumably, the "ether" he's mentioning is
diethyl-ether, C2H5OH5C2). I'll admit I know little about
engine starting aids, beyond the existence of such things
as glow plugs in diesel systems, and nitrous oxide used
as a power boost in racing engines.

I also know predetonation -- usually because of too low
an octane, fouled plugs, and/or mistuning an engine --
does nasty things. :-)

I frankly don't know why an ether-steam combo would be
any better from an emissions standpoint than our current
ICE, a H2-based ICE (which isn't all that good an idea),
or a H2-powered fuel cell. (Assuming the H2 can be
gotten from an absolutely clean power source, and that's
a very big question mark; the best I can do is PV cells
and there are many issues in the manufacture thereof.)
Also, wouldn't there be a risk of the steam hydrolyzing
the ether, yielding just plain old alcohol? If so, why
not just use alcohol? Butyl alcohol is occasionally touted
as an interesting renewable power source. (I don't know
how good it is compared to biodiesel or battery power.)

In any event, good engineering includes knowing what to
avoid in the making of an engine -- unless one really
does want to make a drivable bomb, in which case one
wants the engine to work and the bomb not to go off
prematurely... :-)
