18hp Olds Type G Hit and Miss Engine

Starting an 18 horse power Type G made by Olds Gasoline Engine Works around 1904. The engine weighs 5,300 pounds. It is sitting on a Bettendorf cart. The engine has 60" diameter flywheels with a 4.5" face. It has a 8.5" bore with 14" stroke and a displacement of around 794.4 CID or 13 liters.

Id love to hear it under load. Its an absolute work of functional art.

[@MegaFPVFlyer]

I can't imagine how much work went into making it start so easily.

[@jossivanderbellen]

It breathes, it farts, therefore it lives... :)

[@turtleman5.9]

In 100 yrs no one will have an LS on a trailer to show off but this thing will still be sipping fuel and doing work. Things just aren't made to last anymore, everything is disposable. Very nice work man!! I could sleep in a hammock to the sound of that thing

[@mitchwest6453]

These are more comparable to small engines, not a car/truck engine like the LS

this is a great old engine and a clever mechanism.....as far as i'm concerned this engine represents the high point in petroleum engine technology and its been downhill ever since.....the world today would be a better place today if no petroleum engine of more than 1 cylinder or 18 hp or less than 5000 lbs had ever been built

I know people will think I'm stupid for asking but what does that engine run on? Oil or gasoline?

[@HeavyMetalEngines]

It runs on gasoline.

[@davidcat1455]

No such thing as a stupid question. There is only stupid answers. Never stop being curious👍

[@FarmAlarm]

I got my first engine. I picked up a 3 hp Fairbanks and Morris Z last weekend. Your 18hp is very nice. It started super easy!

[@therandomman6647]

31 revolution between each power stroke, impressive

[@MrKeithsplace]

Scraped that thing would make 10 cars and a pickup, all of them combined would not last as long as that hunk of iron.

[@SteamCrane]

Olds liked to do things a bit differently. Really nice!

[@BAD_CONSUMER]

if you had a belt and it was under load it would presumably hit much more regularly?

[@HeavyMetalEngines]

Yes, when under load it would hit every other revolution to try to maintain the RPM. This is a four cycle engine with an interrupted exhaust cycle. When the engine is at the RPM that the flyball governor is set to it will lock open the exhaust valve which keeps the engine from performing an intake stroke. When the RPM drops the governor linkage releases the latch out and it goes through the four cycles until at the proper RPM. The huffing and puffing air noise you hear is the air going in and out of the muffler when the exhaust is latched open.

[@erikcourtney1834]

That’s gotta be some really good bearings in those axles🤣 it pulled out so easy

[@bryco32]

Helps that the guy is built like a Brick Shi*house as well

[@Steviegtr52]

I am just making one of these in mini. 1" piston cast rings & 1 1\2" stroke. I can only dream it will coast for over 30 revs like yours. Amazing piece of machinery. Thanks for showing. Regards. Steve.

You made starting that look too easy! Thanks for the preview of the show! Shoot some video at the show of some other cool engines and post it on your channel for those of us who will never make it to that show.

[@JackpineGandy]

I've never seen a large engine like this, before. I'm wondering how it is connected to its load...would that be a large belt running on the rim of the flywheel?

[@HeavyMetalEngines]

It would’ve had a pulley bolted onto the side of the flywheel and a flat belt would have ran off of that pulley to the load.

[@HeavyMetalEngines]

This video of another one of my Olds engines shows a clutch flat belt pulley. kzbin.info/www/bejne/mmSkp5-Dgq-noJo

Question. Did you build the cart? Im doing a 20 horse superior. Currently building a cart. Found some hansome big wheels for it. There tapered hubs. Did you build your spendles?

I did not build the cart. The cart is an original Bettendorf cart that just happened to fit perfectly under the engine with no modifications.

[@shanescott8241]

[@stationaryenginesworldwide]

[@welkinator]

What happens when you put a load on these engines? Do they fire more often as the load pulls down the rotational speed of the flywheel?

[@HeavyMetalEngines]

These are four cycle engines. When the rpm is at the set speed it holds the exhaust valve open and coasts. With the exhaust open there is no intake stroke. When under a load it would fire every fourth stroke or two revelations of the flywheels to maintain the rpm that the governor is set at. Does that make sense? It doesn’t use a butterfly valve like a modern throttling engine but instead uses a delayed exhaust stroke by latching the exhaust valve open.

[@welkinator]

@@HeavyMetalEngines Yes, so it does fire more often.

Standing on flywheel not smart seen a guy get tossed 15 feet

[@HeavyMetalEngines]

There’s nothing wrong with standing on the flywheel if you know what you’re doing. It wasn’t even close to where it would fire off. I was going on a backstroke and it wouldn’t have fired if I wouldn’t of tripped the igniter. I’ve been doing it for 30 years so I think I know how to start a big engine. Some of my engines are so big there’s no other way to get the flywheel started without putting a foot on it. The key is to just putting your toes on it so if it does fire your foot slips off and away from it.
