Help!
I enjoy reading about boats and engines although I never owned one and have no mechanical skills.

I have tried mightily to visualize the engine described by Peter to Larry.

Only if the single cylinder was bent at say, 150 deg or more, leaving a separation of 30 deg or less, then I could see this 2 cycle engine working if there was a single throw on the crank. But Peter describes a 3 throw crank.

Or, what is the 'bottom con rod on the center one' connected to?

Help!

Prof Hugo Junkers was one of histories most
inventive and prolific individuals in the early developement years of the internal combustion engine. late 1800's to mid 1930's.>
I read some where that he submitted the
first patent on an opposed engine mechanism in
the early 1900's ? He designed and made many marine engines but I have not found a source for this info yet.

Would also like to see schematic of the above mentioned engine!

ok, will try again. vertical engine, piston on rod on middle bigend,bigends eitherside are on same plane as each other but 180deg. to centre one.2 long rods then go up front and rear of sleeve to a crosshead on which another piston mounted upside down fits down open top of sleeve if bottom piston goes up,top one goes down. injector in middle of cylinder.exhaust port controlled by bottom piston, inlet by top. also rectangular scavenging piston on top of crosshead running in casting on which poppet valves are there for air entry. now you are confused! similar to doxford layout i think regards peter

Bravo! Peter, and thanks. I'm still assimilating this, but it is changing from heavy mud to light mud! Is this a possible pre cursor of the Sterling engine?
Thanks for your assistance.

no Don, i think not. it appears these engines not too common then and chances of finding fuel pump fairly slim! may have to fit non original one.

Hi, My wife and I live aboard an old power boat that I am told was originally powered by a Junkers diesel. It was said to be two cylinder, hand start with a huge flywheel. I would love to learn more of these engines.

Peter Dixon,
I see your engine is one of the " DOXFORD " style not at all odd. Have you still got the injector? I think the fuel pump will be a flange mount and if you scavenge around a small unit from a " VILLIERS " or little " LISTER " could be adapted. Food for thought. Maybe look at a little " STUART-TURNER " pump. The pictures on Christian's site, the "einweller is the "doxford " and the "zweiller " is the "fairbanks-Morse style. Another is the TS3 or " Tilling-Stevens " o.p with 3 cylinders, 6 pistons, connecting links to a single crankshaft.Hope this does'nt confuse you.

PETER,
those engines were also known as the "side-rod " type. They were very popular in both truck and marine installations although I had no idea they were made as small as yours.

Thanks Christian and Raymond. had no luck reading German! Christian may be interested in my lanz 15ps stationary engine, no6362 on tony burnell's lanz site.I also own n model Bulldog no 645647, 35 hp.Sorry, this has nothing to with marine tho.I have all of Junkers mk 65 except pump. injector in pieces, so possibly incomplete. Yes pump from single cylinder diesel could be adapted using existing cam but I think a linkage to rack would have to be sorted out.not much of a problem if one still had enthusiasm of 20 yrs ago!I could post some pics of dismantled engine if you are interested. Regards Peter

PETER D.
If you were a little closer I would take that engine off your hands, but as I am in Queensland, Australia and you are where?? we are getting no=where. If you get the nozzle # you can get an approx. opening pressure from other similar injectors, the actual pump delivery capacity is not all that critical, just to get an engine running. It's surprising that when you take a runner to a machinery day and people see and hear it they front up and tell all sorts of stories. I know where there's one, I've got one, all that sort of thing. Any way, keep us posted. Like to hear more/

My father drove lorries with TS3 engines in for a few years in the 50's and 60's.. He still owns one but it's a bit grown in, it was actually driven to the position it's in now and both he and I are anxious to get it running again, unfortunately the cab has completely disintegrated but the engine should be in better shape. I will have this as my project when it's out of the mammoth hedge it now occupies.

Unfortunately my uncle sold all the TS3 parts and spare lorries he had to a collector in the 80's, they would now be worth around 50,000 I imagine.

So I'm just stuck with this rotted one with no spares, although it's the very one he drove for 4 years delivering cattle. It would be meaningful to get it running again and I intend to do all I can.

Please email me if you know of any spares suppliers who may have anything for the TS3.

Thanks,
Jon.

Peter,

Did you ever manage to sort your fuel pumps for your Junkers HK65. I have two HK65 stationary engines with pumps and it would be possible to take photos if that would help?

thanks peter but i have done nothing with it so far. but have my motor boat back on water. will post pics of regal engine for rholcomb soon. there is a stationary mk 65 a couple of blocks from here. may be for sale, deceased estate,it may turn up on ebay. saw an mk 65 in stationary engine mag years ago with lister cs type pump (i think) mounted on top of governor housing, as raymond suggested ,it may be the way to go.regards peter

Sorry that I did not answer again. Do nit try to adjust the opening pressure like raymon told you. Junkers Engines have open injector nozzles. They dont have springs or adjustment screws inside. It just has to be clean to work properly.

Christian, I have spent many years in fuel injection and the only "open" injectors I have seen have been fitted to "air blast injection systems" can you post a pic or give a clear description please of a junkers type
regards rayman
