Default Help with large inline 8 cyldiner natural gas engine.

Here is what i know about this engine. It is a large, aprox. 4400 cubic inch, inline 8 cylinder natural gas engine. This engine was used in the oil industry in the early 1900's. It ran a large air compressor, and a turntable for the pump-jacks. I measured, as roughly as i could, the bore (8 inches), and the stroke (11 inches). The heads say they are a "Quad Valve Cylinder Head Made by Auto Engine Works" with the number/ symbol "$ EC 2501". Each cylinder has 4 spark plugs, with a large ignition system made by regulated by a Minneapolis Moline system, and an on-board transformer. The crank has the inscription:
EFCO 1466 P4
LLOYD 1484 16 11 28 CD
1 9 29 ERIE PA

I suppose i would like to know anything i could about this engine. The horsepower and torque rating would be very helpful. I have not been able to find anything on this engine, not even a picture. I'm only a freshman in college, and i know very little on this subject.

The engine is still in the power station where the engine was used, but the turn table and air compressor air gone. My father said we could get it running. This is on my own property, and i would just like to see this piece of history perform once again.

Very interesting! I have never seen anything even remotely like it. The cylinder head in particular is very strange with 4 plugs per cylinder! Gapping all 32 plugs must be fun.

Please post more pictures; I for one am dying to see more of that beast.

Here are some more. The quality is lower, so i don't know if you can make out the picture of the inscriptions on the crank. Also, the rpm gauge on the this goes up to 1200 rpm.

If there is a stuck valve, rolling it over could snap a rocker arm or worse.

Cartoman:

From the photo inside the rocker cover, it looks like each pushrod operates a forked rocker that works dual intake and exhaust valves.

The big question is what are the smaller valves for, the ones below the rocker arms in the photo?

I've never seen anything even remotely like that engine! Sure glad I don't have to maintain that ignition system. I suppose the distributor cap is set-up to fire the four plugs in sequence so if there's a misfire from the first plug in the line, the next one would try. That way, it would take four tries (each retarded from the other) before a real misfire occured.

I'm still amazed at some of the things designers did (and still do!).

Take care - Elden

Might be for air starting? First photo in post #4 shows what I think is an air distributor (left side of ignition distributor).

Interesting engine! Sure would like to see it running, thanks for posting!

Could those smaller springs be tension springs, they look like they are connected to the rockers with links, pulling them back, perhaps to keep pressure against a roller type cam follower? Just a thought.

Wouldn't you just love to walk in to an Auto Zone parts store with that distributor cap. The look on their face as they tried to match it up would be a good Youtube video

Did some quick cursory Googling last night, but quit, assuming by this AM it'd be ID'd...
There was (is?) an EFCO, Inc, originally founded 1895 as Erie Foundry Co in Erie, PA; per their site they've only built large ind'l presses for the "last 50 yrs" (eriepress.com)...
Oldmarineengine shows Auto Engine Works as the builder of a marine engine called the Capitol...
I'd guess the 1-9-29 was close to it's birthday; it's possible if there's a Brit connection with the "Lloyd" that the 16-11-28 could be the 16th day of Nov 1928, as they often used that form...
Didn't try to run down more info; are the nuts and bolts standard US sizes or oddball (possibly foreign)??
A 1917 ring catalog shows Speedway and Hall 8cyl 8" bores, and a Stirling 8cyl 81/4 bore, but there are probably a dozen more who could've produced it.
Will try to dig more today if time permits...

No i haven't tried turning it over, I figured i would wait until i could get some connections to help me decipher the mechanics of this beauty.

Marcel Peumans,

You know, come to think about it, you are absolutely right. That is an air start system! Forgot about that entirely !

BGunn,

Actually I would love to do that, i wonder if they could try to match the transformer that is mounted on the right side as well.

Bud Tierney

Thank you for your quick research, seems like progress anyway. As for the threading, i do not know if they are Standard or Oddball. I'm assuming they are oddball, and this is when the lathe may come in handy.

I think Roland is right, you can see clearly in the pic they are retainer springs. With the air distributor you don't need valves driven from the camshaft, but I think there are check valves installed where the pressure lines enter the cylinders.

Don't think this is an exact match, but there is a guy on youtube with a LARGE 8-cyl 4 carb 32 sparkplug engine

Don't know if this applies but some engines were made to run on more than one fuel and had extra valves to open up chambers to reduce the compression when on low grade fuel.

Nice old engine. Are you going to try to get it running?

I think with the redundancy in the ignition system it was originally a marine engine.

Back in the late 70s early 80s I worked on a similar engine made by a company called Climax. It had an air starter and ran off of natural gas and methane as it was in a sewage treatment plant. The plan stored methane in a huge steel ball. This engine had two spark plugs per cylinder. I still have a repair manual for it. This one was a straight six cylinder. Elegant as heck too. Cast aluminum valve covers, dual ignition systems, and inspection plates everywhere. Sure wish we could have saved these engines from the scrap yard. There were two at the sewage treatment plant.

I think that's a Sterling.

Well, that youtube video is the closest thing I have seen to this engine so far. I wonder if Sterling ever sub-contracted that Erie business for it's cranks, and used "Auto Engine Works" heads?

Reed Engine

Yeah, I would love to see this thing run. I need to figure out some time to do it first though. Somebody suggested putting Kroil in it, then when I get to working on it, it should be alright to break loose.
