Indeed DERG.

Diesel as in the cycle. NOT the fuel you get at the petrol station.

I see...thats wunnerful if they can do that.

No issues at all then.

Thanks for the heads up

Rabauss,

I answered your PM....but as the reply took me so long, the system logged me out...so I'm not sure if you got my replies.:ugh:...I hope so....I'd hate to have to do it all again....:{

post here and tell me if you got the replies.

The Dean.

This is an interesting subject, never knew a diesel piston aircraft engine existed. Not to sound like a smartass but all the diesel engines in the sky were jet engines to my knowledge. From what I understand diesel is nothing more than jet-a with oil added for lubrication, more or less kerosene.

Hehe, last Summer I spent the majority of the time flying 172s in Ireland. Drove a Mitsubishi truck with a big ass tank in the back. Drove it into filling stations, topped it off with diesel (or red/green diesel if we could get hold of it), drove to the farmstrip, and pumped it straight into the 172.

Not a hiccup in 300 hrs worth of that. :ok:

Hmmm, Halfbaked.

What exemption authorisation did you use??? I know there's a MoGas exemption is there one for forecourt diesel too?? (UK CAA) Plus I think A1 is cheaper than forecourt fuel so I'm not sure why you were doing it.

Deltahawk - two stroke diesel
 
I like the look of the deltahawk project.

V4 (6/8 to follow) two stroke diesel 150-200hp.

No valves
No engine electrics AT ALL
Integral cylinder and head so no gaskets
Water cooled
Turbo + supercharged
Will continue to run with supercharger OR turbo failure
In event of complete cooling liquid loss (water n glycol I think)
can be run indefinitely at 50% power.
No reduction gearing needed (or indeed supported)
18,000ft critical altitude
Runs on jet fuel
Better fuel efficiency than lycoming
Same weight as lycoming
Better fuel availability than AVGAS

The engine's operational principles are shared with the largest
and most efficient internal combustions ever made. Large/huge
marine diesels.

See their web site for more details.

I have no connection whatsoever with Deltahawk.

DA42 Twin
 
Those Diamond twins were a bit lethal with any interruption of electrical power whatsoever.

That needs some debate and consideration. nIt's happened more than once.

Fate 1, FADEC 0: a dual engine failure in a Diamond Twin Star highlights the technical gotachas of FADEC-driven engines. It's a cheap lesson for all manufacturers. | Goliath Business News

Big Pistons Forever 20th Feb 2011 00:26

I am not sure that it is entirely correct to blame the FADEC for this accident. The POH clearly said that a dead battery must be charged before flight. The crew chose to ignore this warning used an APU to get it started ( unapproved procedure) and as a result suffered a double engine failure and crashed the aircraft.

I personally know of one Continental gas powered twin Cessna that suffered a double engine failure and crashed when the aux pumps were selected to "high" instead of "off" at 300 feet AGL after takeoff. The POH clearly warns that against this yet the pilot was ignorant of the limitation. How far do we have to dumb down an aircraft so it won't bite even if you do stupid things ?

No one has mentioned the Gemini engine.

www.ppdgemini.com/

Volume 21st Feb 2011 11:26

Is that Gemini the 3rd or 4th attempt of what was (is) also known as Diesel Air Ltd., Laukötter, Golle or whatever company which presented this engine on the Aero 2001 ?
Since Junkers sucessfully applied this System in the 1030s and built several thousands of them for long range seaplanes it is a little bit like nessie... From time to time somebody surfaces with yet another version of this engine.

BRD SrL of Italy
Developments GmbH and RED Aircraft GmbH in Adenau, Germany
and, fo course Gemini

No response from halfbaked, but I'd be interested to hear from anyone else who has put 'forecourt diesel' in their 'diesel' plane - rather than JET-A or JET-A1.

Wondering about flexibility when 'out there'.

Our present aircraft has a mogas STC for that exact reason (although the potential ethanol content remains a problem).

Fly safe, Sam.

Some dirigibles were also powered by Diesels
 
The Hindenberg was powered by four Damiler-Benz DB 602 Diesel engines, V16's.

Denti 27th Jan 2012 17:01

Sam, centurion engines are certified to run on Jet A1 or Diesel (EN590) right out of the box, or any mixture of both fuels. Dunno about others, but think is possible that austro engines aims for the same certification, haven't checked their website though.
