I’m not sure he will go with ev power though. Can it be converted to a 50cc 2 stroke?
I’m sure, with his experience, he’ll squeeze a V6 into that!
6V71? But only as long as the brake line is not rusty.
Before letting him lose on it, he’ll need to answer the following question: would shortening that A-frame (to the point where it still doesn’t foul on the rear of the buggy) make the equippage more, or less, manoeverable?
It really needs a tandem axle drawbar Ro.
Or a Ducati or Harley Davidson twin converted to turbocharged two stroke diesel.
I’m sure the Brits will do an artic version so that they can reverse it.I count myself as Swiss in that regard.
Maybe random crap maybe not.
Not. Many drivers, especially on the Continent, have a firm preference for either artic or drawbar (steerable of course) driving. I respect your preference for drawbars. Part of this will be because reversing needs a slightly different technique and soon becomes habit-forming and automatic. Which is why I didn’t like rigids. As soon as I reversed one, I’d steer on the wrong lock (did it in my car too sometimes!).
A nice compromise was the caravan-type drawbar (only one pivotal point), which you could still jack into tight spaces but otherwise handled like an artic. Drove plenty of those.
A super-charged 2T diesel I can accept. but a turbo-charged 2T?
It is late at night for me, but I can see issues with that. Scavanging exhaust gases in 2Ts is an issue already, and plumbing a turbo in, so increasing back pressure?
Let him dream Franglias, that’s all he has.
In my case it could be partly genetics.My Grandfather drove a Foden steamer and trailer and I’m sure that wouldn’t have been an artic.I only found out about the specific type he drove relatively recently.
Seemingly promoted from horse and cart.
My Father drove a Diamond T and Rogers during his REME war service which my all accounts he took to instinctively and ironically ended up being given more driving duties than his real vocation of engineering.He had no interest in driving trucks.
While drawbar outfits always looked ‘right’ to me artics just being various oversized variations on the Scammell Scarab theme.
I wasn’t disappointed when I was finally given one to drive on UPS line haul work after passing their assessment which I enjoyed doing.Unfortunately all too late as part of a de railed train wreck of a career.I’m not whining life is what it is.
The scavenging effect increases pro rata with the amount of air you can throw into the cylinder and the resulting combustion.The problem with two stroke is filling the cylinders with enough air during the time available, between the end of the power stroke, opening the exhaust valves to scavenge the cylinder and the compression stroke.Turbocharging solves that problem.
Which is why a turbocharged Detroit is more powerful than non turbocharged.
I’m having problems with seat location whether it’s a Harley twin converted to diesel or a 6v92 T.
I can relate to that! Most of my ‘steerable’ drawbar work was with tractors and trailers on farms.
Open to correction, but 2T Detroit Diesel were supercharged with a gear driven blower, not a turbocharger.
The point is that 2T are very sensitive to exhaust configuration and any obstruction, such as a turbo is problematic. Pushing more air in, is good but at the cost of obstructions in the exhaust, clearly less so.
And do non-supercharged Detroit Diesel 2T exist?
Can someone please give Carryfast a lesson on the differences between super and turbo charging.
I really couldn’t be arsed.
So Detroit Diesel 2T all have a Rootes mechanical blower.
Being 2T, and without using the crankcase as on most 2T motorcycles to transfer the air to the cylinder, the engine has no intake (suck) stroke. So to get air into the cylinder, which has hot exhaust gases in it, a blower is needed. Detroit Diesel call these versions NA or naturally aspirated, although they do have a blower.
And to correct my doubts earlier, some do have a turbo fitted as well.
So although some are called NA, they are all supercharged mechanically, and some are also turbocharged.
In a nutshell with a diagram
And a bit better explained
They’re called NA because the blower contributes almost nothing to the compression.
Carryfast’s sudden silence speaks volumes about his ignorance.
