    Elektron has been used in aircraft, Zeppelins, and motor racing applications. In 1924 magnesium alloys (AZ; 2,5-3,0% Al; 3,0-4,0% Zn) were used in automobile pistons diecast by Elektronmetall Bad Cannstatt, another IG Farben company formed out of Versuchsbau Hellmuth Hirth.
    Siemens-Halske used elektron casings for their Hellschreiber military teleprinter.[10]
    Incendiary bombs using elektron were developed towards the end of the First World War by both Germany (the B-1E Elektronbrandbombe or Stabbrandbombe) and the UK. Although neither side used this type of bomb operationally during the conflict, Erich Ludendorff mentions in his memoirs a plan to bomb Paris with a new type of incendiary bomb with the aim of overwhelming the city's fire services;[11] this planned raid was also reported in Le Figaro on 21 December 1918.[12] The lightness of elektron meant that a large aeroplane like the Zeppelin-Staaken R-type bomber could carry hundreds of bomblets.[13]
    The British and German incendiary bombs, used extensively during World War II, weighed about 1 kg and consisted of an outer casing made of elektron alloy, which was filled with thermite pellets and fitted with a fuse. The fuse ignited the thermite, which in turn ignited the magnesium casing; it burned for about 15 minutes. Trying to douse the fire with water only intensified the reaction. It could not be extinguished and burned at such a high temperature that it could penetrate armour plate.[14]
    The bodywork of the Mercedes-Benz 300 SLR racing car was made of elektron. When it crashed and burst into flames during the 1955 Le Mans race, spectators in the stands were showered with burning debris. Stewards pouring water on the fires only made things worse, and the wreck burned for several hours.[15] In addition to the driver Pierre Levegh, the death toll was approximately 80 to 84 spectators, killed either by flying debris or from the fire, with a further 120 to 178 injured.

    This type of engine was obsolete in the 1930s, and you can't get much power out of them because there is no cooling between the cylinders. I have never ridden one, but am told they have great torque and get terrific mileage.

    Thinking about buying a non running 1961 Sears Allstate Puch 250 Deluxe. I finally found parts online at Motor West thanks to your comments here. I appreciate you sharing that knowledge. Still on the fence whether to buy or not. It has zero rust and seems to have compression. In great shape really. Has about 5k miles, but I hear that is about top end rebuild time for those twingles. Do you have any advice on this? I am a mechanic, but I also want something vintage to ride! This thing might just be different enough to keep my attention...

    • @Adventurepilot70
      @Adventurepilot70  11 หลายเดือนก่อน +1

      Glad you have watched my channel. I hope to get back on my own Twingle project soon, as I am almost finished with the airplane.
      It sounds like you have found a real good one there. With only 5000 miles I would think all you would need to do is to decarbon the pistons. Only reason I think this is, you don't know what kind of oil was used. We didn't have very good oils back then, so I would make sure the rings are not stuck. Be sure you put the same ring in the same position and on the same piston. Got to get any carbon that is behind the rings cleaned out with a dental pick.
      Other than that, nothing to do in my opinion. I am not an expert on Twingle engines.
      Should be good for 10,000 miles with the oils we have today.
      Good luck with it.

      I think they did make some with a third cylinder on the bottom for more crankcase pressure, but they were water cooled, as the problem is cooling between the cylinders.

    • @Adventurepilot70
      @Adventurepilot70  2 ปีที่แล้ว

      No. They were 2 cycle engines. There is no oil to change in the engine, and no oil filter. These engines get fresh new oil with every breath they take, so they only see clean new oil. This 250cc size has oil injection, so clean two-cycle oil goes into a special tank.
      The only oil you can change is in the transmission and primary chain case.

    Can/Should the 6.2 to 1 compression ratio be increased?
    By milling the head??
    Doming the pistons???
    Increasing the Revs?
    Or would any power increase be gained?
    16 HP from 15 CID is pretty lame...
    Ditto: 5200/5800 rpm's
    Seems like it was designed for the 80 octane gas of 1930s/WWII Europe...
    Russia/East Bloc 1950s....
    Neutral Austria...
    J.C.

    • @Adventurepilot70
      @Adventurepilot70  4 ปีที่แล้ว

      It would be easy to mill the head, but increasing the compression by very much would be dangerous. Problem with this design, that I can see, is cooling. The two parallel bores have absolutely no cooling between them. This is because they must be very close together.
      Cylinder distortion is going to be a problem with this design. Cast iron is a very stable material to make the cylinders from, but slow to dissipate heat.
      The long and convoluted scavenging route would make it hard to get more revs, and the pistons are very heavy. One good thing is that I think this engine would be a very efficient machine for a two-stroke, and maybe give good fuel economy for the power produced.
      I will be happy with the 16 hp produced. Sears claimed a 68 MPH top speed.

      @@Adventurepilot70 It will do more than 68 mph. I had a '65 for a few years in the late 60's. I threw papers off of it. I rode the hound out of that bike and had it up to over 90 mph when the engine seized. I went over the handle bars, but somehow held on while the bike skidded for (it seemed liked) ever. Just before I stopped the engine started turning again. I wore a flat spot in the rear tire over that incident. The bike continued to run, but being young and dumb I never really understood much about 2 stroke engines so I gave it to my neighbor who was a mechanical genius. He re-ringed it, fixed the gen and had it running like a top in no time. Could still get parts easily back in '69 and '70.
