I know of one compression ignition engine that runs on kero/oil only.....the fascinating LOHMANN bicycle motor from early 50's...
The little 18 cc Lohmann has variable compression, just like a model engine.

Sorry for re-posting these pics in the same's a cool device though...

Starting a smaller diesel without ether may be more tricky (I haven't tried it though)

I wouldn't advice use of an electric starter on a smaller's simply too easy to damage the conrod/crankweb.
Practising the ®diesel flick' is'll never look back...

Schlosser diesel .5cc R/C

Schlosser .5 cc RC diesel vs PAW .5 cc
See the Pee Wee box for size.

These little gems will never see an electric starter.

John, why does it look like the Schlosser has a loose head screw?

Electric starter? On a diesel?? Blasphemy! To say nothing of bent rods, busted cranks, etc...

I just got in a couple of new MP-Jet model diesel replica engines. A MP Jet .040 PB and a 1.8cc Atom engine.
I plan on running them this weekend if I get the time.

Loose head bolt

Gkamysz (Greg) for the loose head bolt, see page 116 post #1736. Sorry, I didnít realize the postings were going to get so stretched out and far apart.
Iím not really trying to see if everyone is following along! Youíre the first to notice and ask. Iíve taken (was taking) the Schlosser apart to have a look inside. It has very nice, modern porting, show everyone later.

Earlwb, your new MP-Jet model diesel replica engines look great. How about putting them together, the MP Jet .040 PB and a 1.8cc Atom engine for size comparison? Any chance you might make us a video of them running, we would love to see it.

Nice Tribe

Wish I had a few , but my Silver Swallow will have to do and it fired up better with fresh fuel, hope its calm tomorrow, its no Mk17 I like the quirky chinese engines it gives me some scope to do a little machining on them

Earlwb, that's a very good comparison. The Atom is a lot bigger than I thought it would be for 1.8 cc. Those are all great looking diesels. What size props are suggested for them?

They suggest a 11/5 or 12/5 prop for the 1.8cc Atom engine.
and for .040 PB engine a 7/3, 7/4 or 8/3 or 8/4 prop.

I also scanned in the instructions and put them here:

Earlwb, you’re making these diesels look very tempting. Not only do they look great, and appear to be well made, but they should be excellent runners. The Atom (1.8 cc) specs listed a 12x5 prop at 6500 rpm! That’s a very “torque” little diesel. Did you get them in the US or over seas? Thanks.

This type of design in model engines had very long strokes in comparison to the bore. Plus they are a side port design. So they do not rev up high. Back then even the ignition engines did not rev up high either. But it helped them to sound more realistic in the free flight planes they used then. The free flight planes tended to fly off in a more leisurely sedate manner when launched by their owners. In some countries like the UK, just after WWII they had restrictions in place as well, for example you were limited to a max of 45 seconds of engine run time. Which is one reason why the engines all have cute little fuel tanks on them. The fuel capacity was designed with that in mind. RC was only a dream with modelers just after WWII.

I really like the cool spun aluminum fuel tanks on these little engines. Not plastic. Plus the assembly joints on the fuel tanks is almost invisible too.

Now some people in another thread were commenting that the 1.8cc Atom replica seemed to be outperforming the larger 2.5cc Letmo replica as well.

I bought my MPJet .040 and MPJet 1.8 from ICARE in Canada
But I think Carlson has them too. But you need to call him as his website is out of date:
