IC 2 Cylinder Horizontal Engine

[kuhncw]

Chuck, nice job on the twin cylinder.  As Gary said, it's got the good old John Deere exhaust note.

I'm  looking forward to hearing the engine with generator load.

Well, this is interesting.  Today I modified the fuel tank, making it shorter and changing the fuel outlet to the bottom of the tank.  Engine runs much more consistently and for as long as I keep the ignition on.  As a matter of fact, it keeps right on running even after I turn the ignition off!

It had dieseled for 30 seconds or more before I pulled out my camera and started filming.  I finally stopped it with my hand at the end of the video.  Never had a model engine diesel on me before.

Interesting stuff Chuck!! I've never seen one do that either. Now you've got one that won't stop running and I've got one that won't start.--Strange days indeed!!!

Combination of increasing compression ratio and it getting hot? Still, thought 6:1 would be way too low to cause pre-ignition! Is there a sharp edge somewhere in the combustion chamber that is a hot spot?

Haven't started the engine since it was dieseling a couple of days ago.  I did continue work on the generator.  Here are a couple of pictures ready for it to be installed.

Very interesting Chuck, I have never seen one diesel like that before either. Will be interesting to see what you find as the cause of that...man it was running good too!!!

Not sure what was the causing the dieseling.  I think it's just getting too hot and probably needs a cooling fan.  Here is another video with the generator and light hooked up.  Got it running pretty good right now although I'd like to slow down the idle some.  Unfortunately, it needs a heavier load and the 110 volt, 60 watt generator just isn't enough.

Think I'm done with it for now.  Gotta get back to work on some of my other unfinished projects...

Very nice!!

Always fun to watch your builds progress, I learn a lot (just went back to one of your tips on taper locks for flywheels yesterday, added that to my pile-o-learnings).

She's a great runner Chuck and alway and inspiration to follow your threads......

Good stuff, Chuck. Now if the lights go out, neither of us will be left in the dark!!!---Brian

Excellent Chuck. Congratulations.

110V 60 Watt is impressive to me.

Chuck,
Glad to see that you have your engine sorted out and running. I've been away from the computer for a few days and missed some stuff, Congrats. I recall that Dale Detrich often uses belt driven fans on his engines . A guy at the Badger steam & gas show has a generator and uses a computer fan for cooling. Just a thought.

Here' the photo he also has a bit more cylinder separation than you.

Nice running engine Chuck!

A good runner, this twin cylinder, and powerful  too, he certainly could drive a air fan also !
Dieseling occurs generaly when a part inside cylinder gets and stays red hot, the  sparkplug or carbon deposit (if your engine is running rich).
You can also use a less volatile fuel, with higher contain in C8 and C9 to fix dieseling.
I like the way your engines are built, the steel base and main frame, your personal touch definitively.

Very nice     

Based on my horizontal engine yours should be good for a couple of hundred watts. I ended up gearing my generator up 1-4 to get enough load. Did you make any voltage or current measurements while the engine was running?
