Cozy, Long ezy, and diesel engine.

Please excuse my ignorance, but I've been reading a lot of hoopla over 2
stroke diesel aircraft engines. Has anybody tried one of these in a Cozy or
Long Ezy? It sounds to me like that may make for a very fuel efficient
aircraft with good performance. Any reason why it can't be done?

If the aircraft is home built, could it burn standard diesel even though it
hasn't been approved by the FAA? Is there a good reason not to use standard
diesel other than fuel congealing at cold temperatures?

I am no expert, but I'll give it a shot.

Problem number one, they are all in test phase, or prototype, and not
available, AFAIK.

Nope, and when they are out there at reasonable costs, lots of people will
be wanting to get ahold of them. Problem now is, they have been going to be
available to the public in the next six months, for the last five years.
Get my drift?

Some people are home-brewing 4 stroke diesels, from cars, and had pretty
good luck. I recall one being in a pusher.

hasn't been approved by the FAA?

For experimental, you could burn peanut oil, as far as the FAA cares.

Is there a good reason not to use standard
diesel other than fuel congealing at cold temperatures?

Sounds like a damn good reason to me! :-)

One of the big reasons that people want diesels, is that they could burn the
jet fuel that is at all major airports, and lots of minor ones. g

No, so long as the power is there to take off before the end of the runway.

US diesel is full of crud (someone else can tell you exactly what). If you
could filter it, it may be okay, but for me, I would just as soon go with
Jet A for the price.

You're saying that they just aren't available, not that they wouldn't be
efficient when they're available, right?

I thought those had some weight issues.

True, but that issue can be fixed.

Yea, but standard diesel is much cheaper.

Right

Some have done a pretty good job of keepng the weight down, and it really
matters what you start from.

Sounds like a damn good reason to me! :-)

True, but that issue can be fixed.

That comment was about fuel jelling. What are your fixes? Will it end up
making the cost higher? What happens when you go to other airports that
don't have auto diesel fuel?

The first fix would be to pump extra fuel through the system so that it can
be warmed by the engine, then returned to the tank. Perhaps you could even
run it through the oil cooler before sending it to the engine. There are
also additives that are routinely used to keep the fuel from jelling.

My understanding is that these engines are actually multifueled. You could
run them from diesel fuel, Jet-a, or any combination of the 2.

If I understand the issues correctly, the turbo charged diesel engines
retain most of their power even at high altitudes (around 25K). And, they
give about 30% improvement in fuel efficiency over av gas.

Please understand you're speaking to a complete novice here. I was hoping to
glean knowledge from you guys.

Thanks, that is a cool sight! Apparently they will have the engines for sale
next month.

The additives will be the best bet, but expensive, when you add that to the
price for fuel. Truckers use it, but they are only dealing with negative in
the teens, not 20 to 30 below, with a huge moving air factor, around the
fuel. All that fuel, basicly in direct contact with the air, with Al's
great thermal conductivity. You would need to insulate the tank. Not easy,
and more weight. Now add in whatever fuel heat exchangers, lines, and
pumps, and more weight, and also, complexity. (read ways to bring you down
before you wanted to) I didn't do any calcs, but you would need to capture
almost all of the engine's waste heat to do this without additives.

I realize that you would not be in that kind of temperatures all of the
time, but all you need is one time where things were colder than you
thought, and......

Many around here will talk about the hassles of using your own auto fuel,
and what happens when you travel away from home. That is what the airplane
you are describing will be good at; great economy, and legs.

Shoot, one nutcase that hangs out around here even made his own fuel truck
to feed his habit. g

The old saying about asking how much fuel that yacht burns? If you have to
ask how much fuel it burns, you can't afford the boat.

Same thing here. Jet fuel is not that bad, it will give you great economy,
and it is available, and won't end up killing you. Just my humble opinions.

Good sig line.

Tell you what. Get out your planner, then write down in one month, to check
and see if the engines are shipping, right then. If not, write it down to
check in a month. Repeat as necessary.

There is some Latin saying about my attitude, but I don't remember it.
