Another live "Diesel" (petrol)

Post by Titan » Thu Nov 19, 2020 12:05 pm

First post for rather a long time! Well I have a nice little project for the lockdown, there has recently come on to the market an absolutely gorgeous little petrol stationary engine that I feel is just begging to go into a 16mm scale locomotive. It has several characteristics which make it particularly well suited including:
  • Four stroke
  • Low Revving
  • Water cooled
  • petrol powered
It is also very heavy as it is pretty much solid brass and stainless steel, good for traction at least!

So I could not resist! Here is a video of mine running:



A few observations: It has a wet liner around the cylinder, but the head is not cooled. This is not a problem, because the engine runs very cool and as the brass is both a good conductor and heat sink there is sufficient heat transfer to keep the cylinder head at sensible temperatures. It also means that it's water usage is quite slow as not much evaporates let alone boils. I can get through several tanks of petrol without needing to top up the water. Ignition is provided by a module and a single AA battery concealed in the base.

Now as it happens, it appears to be a fairly close facsimile of a Deutz diesel:



And not only that, but this type of engine has been used in narrow gauge locomotives:



So whilst my loco will be freelance, it is good to know that it is not un-prototypical
It's a Mamod Jim, but not as we know it!

Very impressive piece of engineering, I couldn't use one myself but will be watching with interest, and admiration!

I have to say, that looks superb idea, can't wait to see it being built :thumbup:

This is the beast:

I got mine a little cheaper than that as I had some voucher codes.

I'm a steam man through and through but this has even captured my attention. I'm also watching with interest. :thumbright:
