Moskito-Permot 1.76cc

Here are some pictures of the Moskito-Permot 1.76cc (about .107 cu inch) an engine made in Glashütte, East Germany, during the early 70-ties. They came in both glow and diesel form in sizes 1.5 and 1.76cc, both looking the same from the outside (identifiable by a stamp on the mounting lug). There was an intake choke offered but no muffler, as far as I know. The cylinder is separable from the crankcase but not rotatable, the exhaust needs to face the rear due to the very special gudgeon pin attachement. It is hollow with a rivet looking aluminium part that stops in from falling out the rear, but may well touch the cylinder in front...

The engines show typical eastern europe roughness inside but noting that can not be fixed so far. The diesel version had a huge piece of hardened swarf in the crank that I luckily found and removed before the first start...

It fires up easily on a prime, will run it in further when the long winter is gone here. I've made crude header from aluminium and will fit an after muffler onto that.

There are some gems among the Eastern European engines and these are two of them. It is very difficult to source any history as they pre date the interweb era.

I see quite a few of these being sold from Poland, Germany and Bulgaria along with Eastern European engines in general at "bargain" prices but I have been reluctant to participate.

The recommended fuel (unless my German is off-kilter) is strange.

For the diesels ether Crude Oil, ether and castor oil or Diesel Oil, ether and castor oil. That will be one messy and smoky exhaust!

The glow is no nitro.

I like the header - how did you make it?

Does the glow and the diesel share the same rod? That looks like that engine would be getting a serious does of vitamin N !!!! I have some of the Russian Meteor engines which resemble that cast finish appearance. Surprisingly, the Meteor regardless of the interior crudeness and axe like methods they used to build it, runs rather well. Ken

Yes, the rod and other internal look the same, I guess the liner is the only difference with a counter piston for the diesel version.

Yes, the fuel recipes look funny, I don't know how or where to get crude oil around here...
Diesel oil in this case might be very similar to Kerosene. My had uncle hat a hot bulb engine in his boat when we were kids, those would run on almost anything and sounded great.

The header is a very crude job, I don't have the tools for something proper. I've split an aluminium tube at one end and attached it (with JB weld) to another Al-piece that's fits the mounting face. By splitting the tube one doesn't only rely on the JB-weld, in theory at least...

Nice Looking engines Kris , are you going to use them on airplanes or run them for fun ! getback

I do like to run my engines, so I'll run them on the bench first to see what they are like. If they behave well there, then I'll put them in a plane too. Smile

I'm tempted to put a proper RC carb on it though. I think an Enya .09 carb can be adapted fairly easily, it needs a thin spacer/collar to take the diameter from 7 to 8mm, plus a bit of shaving from the length of the neck. I did something similar to a Philtech engine once, and that turned out just fine.

I think "petroleum" translates more like "lamp oil" than crude... Close to kerosene (by kerosene I mean "jet fuel").

In Finnish language "petroli" means lamp oil, or a petroleum distillate a little lighter than jet fuel, back in the '60s it was used for heating in some places (kinda like "kerosene heaters" in the U.S.) and even for some boat or tractor gasoline engines.

The terminology can get a bit confusing as we all know, even though it's all supposed to be English Smile

Gas, petrol, kerosene, all mean different things on different continents. Or if a Brit asks an American to light a torch, that can lead to weird situations Very Happy
