Cutaway Engine

[olzed]

Hi guys.

I'm thinking of making a running cutaway L6 engine for a display.

Carbs should be the simplest approach, and running on a couple of cylinders,

with the rest exposed. Oiling and cooling would have to be addressed,

but if it only ran for a few minutes at a time cooling should'nt be an issue.

Has anyone done this before with an L6?

Here is a guy on youtube running a Ford model A engine like that.

Can anyone offer advice on this. Is it feasible? Would it create interest at a car show?

I would think it easier to simply make a cutaway that would show everything in motion-though not under its own power; think of having the machine operate via electric pulley turning the crank. You wouldn't have to worry about fuel delivery, slinging oil, or cooling and the speed could be lowered to show the intricacies and connectedness of all components from crank to pistons, cam to valves...

Setup and breakdown (no pun intended) would be much easier, and you'd not be limited by being indoors (exhaust, fire hazard from gas, etc.)

Whatever you decide to do, it'll be interesting to see (so take pictures and video!)

The show is to be outdoors so fumes should not be an issue.

To have a straight six chuffing under its own power alongside some S30s,was to, hopefully, create some interest for the public.

Pictures definately.

Cut away 4to6 and run on 1to3.

You will have to weld up some baffles for water and oil.

You are right Blue. Three cylinders sounds the way to go. Cut the head in half and blank the end. Cut the rocker cover in half and blank the end to stop oil splash

I was thinking of running with no water for short periods . Would that work?

And very light valve springs on the unused valves, so there is not the tension on the cams, and partially block oilways to these to stop oil spray. I guess it's a case of make it up as I go, to a certain extent.

One SU carb feeding three cylinders should work OK.

The L6 will run on the front 3, just fine. I had checked plugs one day, then backed it out. It sounded strange, like a V8 actually, not the same power but running. Couldn't imagine why it was acting strange. Lifted the hood to see that the back 3 plug wires were dangling. Doh!!!

In the mid 60's, General Motors along with the local dealership, donated a plastic see through, slowly spinning, Chevy 194, in line 6 engine to the School's Automotive Class. Everything worked, it was a 'see how everything works together'. model. Never thought about making a working one though. I say, go for it.

Brian,

I think that if you do it and post some high quality vids on youtube, it could become a very popular reference for most car enthusiasts.... especially those with German I6's as the Z motor is a Merc descendant.

Bring it to the 2013 ZCCA event too!

I saw the old ford cutaway vid and wished the quality was better with more close-ups.

but as mentioned above, hitting the crank with an electric motor and a cutaway would be easier (especially for shows inside).... heck cut away a manual transmission for greater observations and drive the whole thing from the drive shaft spline or crank nose. Just grease the parts that rub should be fine for room temp slow-mo demos... no need for fluids.

Some of those fluorescent plug wire inserts to enhance the firing would also be nice.

No it isn't.

If you want to create something truly fascinating, how about putting a huge flywheel on the engine and making it a one-cylinder hit-and-miss engine? You'll need to make a few parts, but when you're done, you'll have an engine that can turn at extremely low RPMs and will go "chug/poof/wagawagawagawagawaga..waga...waga.....waga.....waga.... chug/poof/wagawaga..waga.waga..waga"

Please correct me: I had read that Nissan had licenses from Mercedes for the initial design process they used and from SU for the initial carbs.

Ha. That made my day.

I like your ideas.:bulb:

What size flywheel do you think Sarah. Four feet? I doubt the starter would spin it.
