fascinating idea: 2 stroke diesel driven prop plane.

wonder if it clangs when its cold like my fleet?

Private Pilot magazine did an article on diesel airplane motors about a year ago, they had to go to Germany to find one....

hmmmmm... put WVO in it? how would you heat the oil to keep it at the right viscosity. hmmm.... maybe biodiesel would be best.

I recall reading about aircraft diesels being designed to operate on Jet A. Was I having a moment?

Seems like a good idea,though. I'll wait 'till more popular.

Diesel at larger airports may be available; but for a single engine Piper or Cessna, where it's greatest strength is that you can get in and out of any mom and pop airport, diesel or Jet A fuel is few and far between at those airports.

I'm also not sure what happens to injectors with both fuels,separately or mixed.

Diesel avation fuel?

Would a diesel be immune from intake (induction) icing? No venturi, no butterfly, no icing?

Packard Motor Car Company once billed itself as "Master Motor Builders"...in addition to their excellent auto engines, they also built the WWI Liberty aero engine (many found their way into race cars, speedboats, and other uses); the WWII "Merlin" Rolls-Royce aero engine (in fact, Packard simplified the design, actually built more Merlins than RR). They had a huge program for marine engines, and PT boats were driven by THREE enormous 12 cylinder Packard marine engines...Packard engines were still working in several minesweepers and other craft as recently as 10 years ago.

BUT Packard also had a diesel aircraft engine as early as the '30s. No details available here, but the plane housing it seems to have been a heavy biplane, which might have the extra "lift" needed to get such a heavy plant into the air. Also possible that Packard diesels found their way into US airships during the period.

Just an interesting side note...MB and Packard shared a lot of common factors in their products and the way they approached business.

Some interesting discussions and links over HERE on the diesel airplane topic

The Germans were famous for building diesel airplanes before and during WWII. Jumo engines. Some were quite big.

I wanted to put Zoche or Deltahawk two-stroke diesel in the plane I'm building, but they keep upping the price out of my range.

I'm going to use a Mazda rotary instead.

Jet A is basically kerosene which we know diesel engines will just run fine on.

Current companies looking at offering diesel aircraft engines are:

Zoche
Thiebert
Deltahawk
Continental

I'm sure there are others I am forgetting.

Jim B,

Check the Wright-Patterson Air Force Museum site for info about Packare aeroengines. I don't know that they have anything but if anyone does I am sure it will be they.

I was in the museum a few years ago and thought it was much beter than the Smithsonian. I probably thought this because I found a Sturtevant aeroengine that was built by my great grandfather in the early 1900's. Also, you can actually wonder about and touch the aircraft on display.

US Armed Forces ran their diesel powered vehicles on Jet A during Gulf War I.

I work for the FAA and there are several German ultra-light and light sport aircraft that use diesels. There is also an American company that makes an uncertified diesel for amateur built aircraft.

Also, a couple of aircraft companys in the US are researching certifing a diesel for general aviation.

diesel airplane threads.

Some Zeppelin’s were diesel.

I had heard of the german diesel engine used in at least a few examples of their ww2 bombers. Never thought I would see a block until I toured the aviation museum in Ottawa, Ontario. It was not a good engine as changing the speed during operation was a very slow proceedure apparently. It appeared to have two crankshafts with pistons facing each other in a vertical opposed fashion. I almost wondered if two pistons shared the same bore? I thought rated horsepower was 600 but cannot remember. Anyways a fairly small block for 600 hp at the typical shaft speeds of that era. Do not remember the german engine builder either.
