Default RE: Tiny Long Lived Diesel Engine?


ORIGINAL: jerryp8472

<meta content="text/html; charset=utf-8" http-equiv="content-type">I would like to build a tiny generator, just to charge phones, ipods ETC. It's just a little project for when I get bored. Is there a tiny diesel 1cc(or so) engine in existance that could run steady for any real length of time?(Hours perhaps) I'm not sure how big RC engines get, or if there is even one that would work. Also, is there one that runs on regular diesel, or perhaps diesel with an additive? Thanks!
Personally, I would be looking at any old time long stroke, piston ported, two stroke marine engine.

But what worries me here is that you state "one that runs on regular diesel, or perhaps diesel with an additive." Model diesels do not use anything like 'regular diesel' fuel.

If you mean regular 'model' diesel fuel then a model marine diesel has these advantages -

A heavy flywheel to keep revs down and doubles as a pulley for a starter cord.
The end of the fly wheel is also an excellent power take off point with a universal coupling normally being present.
They are usually built strongly and the water cooled head will cope far better with 'hours' of running than any aircooled engine.
(You should not need a water pump as convection flow to a reservoir tank should be sufficient.)
And most should have an exhaust extension that will carry away oil and fumes.

I think that a certain well known auction company with its UKbranch would be your best bet for an old time marine diesel!

P.S. This type of engine but with an exhaust manifold might suit you -
