But at least it wouldn't be carrying raw fuel out into the exhaust at the same time. (Would still be carrying some amount of oil mist, though, I'd imagine.)

Really like that old truck, Tamber. Thanks! So do I, despite it being a lot of work yet. (Hoping to get it back on the road before I start thinking about engine swaps, but one of those ISF 2.8 Cummins looks to be just about a perfect replacement for the Bedford 300, power and torque-wise. That's a ...

I... uh, um. Er... Letting the side down... :oops: A lot. :oops: (I'm mostly here to gawp at the build threads... :oops: ) I don't even have a motorcycle license, and neither of my vehicles is diesel (Though at least one may become diesel in the future. See if you can guess which!) because I rarely ...

I figure I can strip them of injectors and other goodies. What's another plastic bin of spare parts in the garage?

And you just know you'll be kicking yourself if you don't strip them for parts, then you end up needing something they had on them. It's always how it goes...

Off the top of my head, you put the UJs at each end of the shaft out of phase by 90 degrees.

Ah! Explains it better than I can. http://jniolon.clubfte.com/drivelinepha ... asing.html

Megasquirts can't run diesel engines, unfortunately, AFAIR.

Damn, that thing hauls arse; sounds good, too!

A little bit on the other end of the spectrum from most builds on here, I think.

It appears that way. Be interesting to see how well it works out.

Is that a 2-cyl Listeroid in there? Certainly looks to be interesting.

I could be wrong on this, but you'd either have to go through IVA, or Motorcycle SVA (I was fairly sure SVA had been phased out, but it's still listed on the fees poster. Who knows! :D). I'd recommend checking the IVA manual to figure out what you'd have to comply with, if you have to go that route....

Certainly an interesting looking bike. Looks very sci-fi. And it sounds almost vaguely practical.

No-no, port scavenging always leads to some oil burning in the case of intake ports (oil enter cylinder) and, worse, oil exhausting (oil exit through exhaust port as piston ring passes). That's why uniflow scavenging uses exhaust valves and intake ports, mostly. Oil loss through ports: Dry sumping ...

I'd be interested to hear how you stop the sump draining out through the ports; I was dinking around with some (bad) plans for a flat twin 2-stroke with piston porting; couldn't think of anything reasonable. (So now I'm dinking around with some more bad plans for an inline triple. :p (I can dream, c...

Two-stroke? Could run into emission problems burning lube oil. Also you need piston heads with skirts the length of the stroke which would make the cylinders longer. You might be able to avoid burning your lubrication oil if you don't use crankcase compression, but an external scavenge blower, to g...

Whilst this thread has resurfaced, and is reminding me; my dad -- an old HGV mechanic -- mentioned something a while back about Bedfords running with a chevy straight six; where they changed the heads slightly (apparently to change the compression ratio), replaced the distributor with a DPA pump, an...

I don't think you're supposed to be able to turn it over that easily. Sounds like it's lost compression; since it should be resisting pretty stoutly at TDC. Perhaps the piston rings are gummed up?

Bah, humbug.

Have a good day, and a decent new year, everyone; try not to drink too hard.

Who's the owner of that lovely-looking Royal Oilfield conversion I admired in passing outside Horwich's Tesco Extra tonight (27th Oct)? :) Nice to see one in the flesh^Wmetal, as it were. Didn't get a potato-cam (Yes, my phone is *that* bad.) picture; and it'd be a little creepy to hang around. :P (...

I thought in US the engine had to pass a standard as a stand alone. NO distance involved. I would guess that, for static engines such as generators, it would be a per-time measurement. (Per-distance would make no sense for a static application, of course. :D) However, I was thinking only of transpo...

Probably not, if my understanding of it is correct. That is, if you travel a fixed distance X, and produce more than Y pollutants, you fail. So even though the theoretical bike with 160 mpg is more fuel efficient, that's not what's being counted. If it were "grams of pollutants per distance tra...

In theory it should work; but then again, in theory the gap between theory and practice is very small...
Sounds like an interesting idea, though! Hope it works out well! (Or, at the very least, that you learn something new; if it doesn't work. )

Well, it may interest you that your totally wrong on this point! Maybe you should google a bit more before making these kind of statements. You are talking about a variation on the 2 stroke principle that uses one or two valves. I am talking about 2 stroke engines without valves. For instance Sachs...

Without the dedicated exaust stroke, this is ALWAYS incompletely accomplished, so the next cycle has some exaust gasses. Isn't a similar thing done deliberately for emissions reasons? (And, naturally, one of the things ripped out by people who don't care about emissions reduction; since it costs yo...

Further to above, I'm still not going to weigh in on whether or not they're any cleaner running than 4-stroke engines; since I don't have enough data. I shall, however, make a note to add it to my ...voluminous list of things to do. As a matter of opinion, though; to my mind, it should be no worse t...

If you can get an oil with good lubrication qualities wich is also combustable without producing smoke than 2 stoke will become widely accepted again. I'm not quite sure what burning lubrication oil has to do with anything. It may interest you to note that two-stroke diesels don't work in the same ...

Hmm, looking at the nice little graphic they've got there, and one thing stands out to me: They don't seem to be comparing things entirely fairly; careful choice of models to get the best results for their survey, perhaps? Surely it's common sense that a vehicle with a larger engine is going to cost...

For us Yanks, what does SVA ad DVLA stand for? SVA: Single Vehicle Approval -- The test a home-built vehicle must go through to be legally allowed on the road. (A lot of it is common sense, like "no sharp edges", etc.; other bits are utterly confusing even with the handbook (Approval of m...

The only thing missing would be the uniqueness of the build eh? And all the Fun of making what you have, fit. Only slighly more seriously, I think you'd have to get rid of everybody to stop nutters*ahem* enthusiasts from customising, or building their own. But the ability to be able to get a part t...

My apologies if this is the wrong place to put this (I was going to put it in 'Engine Related', but I thought it fit better here...). I also make no guarantees as to the practicality of my idle wanders into "what if..." land. ;) So! This is just a 'little' idea I had tumbling around my hea...
