Is that a flat 4? I've never seen anything like it.

Detroit Diesel made a "pancake" variant of their 2 stroke engines, for bus applications, it went under the floor of the bus, they put them in a lot of those typical American yellow school buses. I still occasionally see them, they have a distinct sound. I'm sure there are tons of them plying the roads of Guatemala.

thought they were just a inline 6-71 on their side?

you mean to tell me, that they were a different engine all together?

Well that's just cool. Thanks for that.

I wonder what kind of spray pattern the injectors have.

probably some weird, flat fan shaped spray pattern i would guess?

I would think the had to cast it a little differently, to lay it on it's side, rather than just change the mounts, or else you wouldn't end up with the oil on the bottom. But I think the internals are all the same as the other 71 series engines. I was merely making a comparison.

Anyway, a "flat" engine isn't necessarily horizontally opposed, though people interchange the terms. I think that's where we got confused. But it looks like this thing is an entirely different beast than either. I had assumed it was some kind of flat engine.

its a 3 cyl, with 6 pistons, and one crank.. has huge "rocker arms" for connecting rods..

and look at the VWs, they lay those buggers over on their sides in the vanagon.. and they use an upright engine..

the 6-71 pancake isnt flat, its still angled for oil to return to the pan, but you already knew that..

my grandpa said that they really arent that much different from a normal inline 6-71 jimmy..

2 stroke is bad for emissions.

I don't quite see why though...

On a gas engine, of course, you get a lot of oil burning and unburned fuel, but with a diesel? I would think that all the diesel should be burned up in the down stroke, and then it exits the engine on the up stroke. Of course, you get some leftover exhaust in every fresh air charge, but new diesels have EGR anyway so there's already exhaust in the intake air.

The only reason I can think that the old Detroits smoked like they did, would be that leaner the injection systems they used were designed around WWII and didn't atomize the diesel fuel effieciently like a modern diesel does, and maybe injected too much fuel for the intake charge (less oxygen due to the presence of exhaust). The oil control probably wasn't as good either. But those problems could be solved with a modern injection systems and modern materials and you would still have the advantage of a 2 stroke- a twice as many power strokes per cycle making more power with the same displacement and making it more efficiently, with less energy wasted to keep the engine going.

with a diesel, i dont see how.. there is no un-burnt fuel/air mix being expelled out the exhaust during scavenging?

the diesel only has air in the cylinder. when the exhaust ports/valves open up, the only thing besides exhaust going out, is air..

with gas engines, yes, 2 stroke is bad for emissions, because of the un-burnt fuel in the exhaust.. but i dont see how a diesel would suffer from the same short comings? the fuel isnt injected into the cylinder until well after the exhaust valves are already closed..

The rings pull oil right out the exhaust port.
