Heinrich Motor hot air engine

Hi All,

I have been given this very nice (what I believe to be) cast iron hot air engine.

It turns over very freely despite having been in a cupboard untouched for 25+ years.

Can anyone tell me more about it?

The D.R.P. with the number is a German patent number I think.

Cheers,

Wilson.

evildrome, can't tell you anything about your motor, but a friend has one similar that was made under licence in New Zealand.

What do you want? A Honda Step Through? Most of this part of the museum is for motor bikes, none with hot air engines, one is a diesel. These little motors were used for pumping water, mainly in rural locations where there was no electricity connection.

Ian, of course I want a full size vintage hor air engine!
I like to go to old tractor and steam shows.
I have yet to see a full size water pumping hot air engine in the last 30 years. Very rare in these parts.
I do remember my father showing me one at a show when I was young. It's a vague memory.

Wilson, have you tried running it?
You'll want to use a light oil - sewing machine oil.
Typically those engines have two flywheels. Hopefully, yours doesn't require it.
From what I've read a Bunsen burner should be enough to make it go.
To get more power try ice water for the coolant. That could help as you dial it in.

It looks as though your motor might need a bit of work to get it up and running, if you don't have it , you might have to make a second flywheel for it, you could make up one from steel, it doesn't have to be cast iron.

Flywheels are needed to supply energy for the complete rotation especially under load.
For no load, I doubt the engine requires both flywheels.
I recommend just trying to get it running as is.
Oil everything with marvel mystery oil and hook up the higher port to a garden hose and heat it up and see what happens.
I've seen too many piles of parts because people think they have to dissemble everything.
