Operation of Jumo 205 Type Briggs Engine Explained

Here I do my best to explain how this 2 stroke supercharged opposed piston engine operates. The design is based on that of the German Junker Jumo 205 diesel aircraft engine built during WW2. The primary differences are that it was a 6 cylinder diesel engine, while mine is a single cylinder gasoline engine, also, I use a piston type blower, while it used a centrifugal blower to scavenge the exhaust. The Napier Deltic is a similar engine, but has 3 crankshafts, and 3 cylinder banks.

What the hell was that noise at about 1:10 ?

@sandsifter149

Sorry, I didn't hear a noise at 1:10, but at 0:59 it is a Deltic starting up ( borrowed from youtube), before that it is a Deltic powered train going by at station at high speed :)

looks like you lose all the oil out of the exhaust side form the exhaust holes

@gary66669

Yes, some oil comes out the exhaust ports. The reason it was SO smokey when I started it, was that oil got into the intake manifold when I tipped it over to re-install the supercharger drive chain. I got out what I could, but apparently there was still lots left in there. I am surprised it didn't foul the spark plug!

Yes, the Twilight Zone was cool :)

Hope your channel doesn't bite the dust, or something!

I have been having some issues answering comments the last week or so.

Generally I try to respond to all comments :)

If these problems persist, Zontaar might have to make a vid about them! :)

@ChargerMiles007 Huh, I logged out, found one of my videos, clicked on my user ID, and got the same message, "This Channel is not available". Weird. So I logged in, found the link for "Privacy Settings", and when I clicked on it, it said "information not available"! Perhaps I am living in.... THE TWILIGHT ZONE.... Which I think was a pretty cool show...

@realvanman1

Yes, it is too strange, and it still does it!

It just says "This channel is not availible", and displays a bunch of other channels.

You sure you aren't Under Cover!!! :)

[realvanman1]

@ChargerMiles007 LOL! Really? I'll have to check into that! I've only got a couple of videos on there, I'm not much of a videographer (sp?)...

[realvanman1]

@ChargerMiles007 Ah, I had assumed- and you know what they say about that- that the exhaust lead was accomplished by drilling the exhaust ports a tad higher in the cylinder. So this means that they must also close 20 degrees before the intake, if I'm understanding correctly? So you actually could develop a bit of boost in the cylinder, assuming the scavenger pump is of large enough displacement... Too cool!

@realvanman1

Man, this is too weird, I went to look at your channel, and it is like it doesn't exist!

Are you like under YouTube Witness Protection, or something!!!! :)

HaHaHa lol :)
