Well I was sure that the china engine. like everything else made in china. was a knock off of someones else's engine that they knew would work. I don't think they spend much on research and development.

While I see similarities between the two the Chinese engine is not really a copy. The intake on the Russian engine for one thing is way different and when the Chinese copy something they don't often bother to re-engineer it much. There have been a few posts on the boards by folks with the Russian engines and they report that they are in fact superior in every way IIRC.

Speaking of copies has anyone ever noted the similarities between the six cyl in early Toyota Landcruisers and sixes of the 40's from the states? Toyota Land Cruiser - Wikipedia, the free encyclopedia

Norman I am glad that my information is interesting to you and a forum...

Jim Спасибо! Thanks!
It is very pleasant to see Russian words!
Yes, on quality of manufacturing the Russian (USSR) the engine, much more surpasses Chinese because it was made at the enterprise which exhausted accessories for military aircraft.
But the engine design has become outdated, between 1956 and 2009 too a wide interval.
But people, such as I, till now go for a drive on motor-bicycles with engines D, because at it the big resource... I very much regret that the factory has stopped manufacture of these s.

Now and to the Russian fans of motor-bicycles it is necessary to buy the Chinese Kits . At us them name КД (Китай+"Д") China+engine "D"..

Here you are right, there are many differences, an admission, the ignition system and many other things. But the idea remains Russian.)))

Talking about similarities...

When I was a child, I had some Russian model airplane engines (about 1-5 cc). Those engines looked similar to the D4 (same fin shape) and worked well, but I could not get spare parts.

Thanky you for the information

Dagger, you should send some of your pics to Fairacing. He does a windows movie maker thing thats really great then posts em on youtube. Your builds would be an awesome addition. Don't know if you have seen it but here is the link; Motorbicycling.com Montage

Spasibo, nostrovia!

(I worked in the Ukraine years back in my well spent youth)((I applaud your English. 2 very different languages and difficult to learn the other))

The D engines are really good and as you say it is a shame they no longer manufacture them. I am sure that they could be made again though and perhaps it will be necessary to do so there in the future?

Thanks for the video's. Here is one of my home town. YouTube - Mall MABness 12:05:08 The Beginning

I still had such engines MARZ, МК-17, КМД-2,5. Engines has bought, and model and has not made.

Dan

Yes, I saw video Fairacing , very interesting. I will necessarily send the pictures of Fairacing...

It will be pleasant to me to see the motor-bicycles together with yours.

Thanks for council.

mabman

To engines of series "D", there was an alternative. But this engine and did not begin to make. I will tell next time about it.
Has looked your video.
Cool! the Bicycle very interesting!
