Steve,
No evidence it existed, but what appears to be a news article shows that it may well of existed before the patent was put in. As for the injector assembly; it seems that is the main problem then. Is a way could be made to produce a more effective way of injecting the fuel then I guess that would solve the problem? I have a few ideas...

Nick, So from what you are saying, it is almost impossible to work at it from that direction? Which is why I was looking for plans... The only other option would be to experiment, but that could take years before success.
:(

Looking at it from a different perspective: With the patent-drawings, you know the inner workings and get a picture what things do. If you've got some photos, you can reconstruct the engine quite well from the proportions and draw you own plans. If you have a lot of photos (whereever you get them from) you could use some photogrammetric software to get the right sizes. With a handfull of photos you will get it quite good by eyeballing sizes.
I have done that with a huge (4.2m high, 9m long, 2 cylinders, 200hp) Diesel engine. But I had about 200 photos with more than 1500 reference points sticked onto the engine. 5 hours work for two people. But that requires access to the original and the owner allowing you to do that.

Nick, I have one crude external picture and that is all.... Not much use really..

As far as I can see the exhaust valve mounted fuelling mechanism is the novel part of the invention. If you change this, then - if it is novel
- you could submit your own patent ! This is experimental modelling rather than scale modelling - and why not ! Thats how inventions come about.
Thats why you must be careful of patents. All it has to be is novel - it doesn't have to be reliable, economical, or even sensible. Then one day someone will be struggling to make the Horwood Engine. However, if you want to claim to have built an Elmer engine, then you have to stick to something that falls with the patent (you don't have to stick to the drawing).
