Thank you great vid. My dad had six wheeler maxi load commer in the early 70’s. One morning with six inch’s of snow on the flat bed I said will it start, he replied it always starts and I don’t think the engine done a full turn and it was away. Still is my favourite engine.
My dad loved the sound of these Commer trucks. A livestock haulage firm I think named J. Watts had a fleet of them in Braunton, Devon. Great memories. Thanks.
Yes not bad for something that was dumped out of an old timber boat. It's got a ways to go yet but it sounds even louder and more powerful in the flesh. If anyone has similar engines or old skool machinery feel free to contact. Keep that old knocker revvin Phil.

I did my apprenticeship working on ts3 commer trucks. The early ones had dodgy pumps and you quite easily have the engine misfire, it would then run backwards filling the trucks cab with smoke.
You can supercharge a petrol 2-stroke - even a simple 3-port type - very effectively. It all has to do with back-pressure in the exhaust. It's not a positive displacement pump like a 4-stroke, it needs a tuned pipe exhaust to work, and it only works properly at a particular RPM for any given pipe. This even applies to the valved 2-strokes (such as Detroit Diesel) - but in that case, the engine needs to be force-scavenged in addition to any SUPERcharging that may be required.
Old bloke I know drove one in the 60s, I remember him saying it did 36 mph, but they had three days to get from Melbourne to Sydney and a week to Brisbane.
This brings back memories TS3`s sound great dont they and if they "runaway" they sound like formula one just before they go.............BANG.........Thanks for posting
@joffeloff You can do a google search for "Rootes-Lister TS3". The first results have pictures detailing the process. It's asymmetrical, after combustion: exhaust ports are uncovered first, then intake ports uncover, combustion gases flush out, exhaust closes, and then intake closes last so air can pack in. I think that a supercharger is necessary, because you need something to force air in straight away when starting it. Turbo wouldn't work that fast, because it needs exhaust gases to spin up.
@@MrBranboom no. these engines have oil control problems, being rings pass the port. it's the problem with the achates engines too. and with fossils on their way out, the achates will not see the light of day.
@Astralism A turbo could work just fine providing it's not the only one providing air. I see in your other comment you too know this - all marine two strokes have turbochargers, anything else would be a waste of the exhaust energy! The patents vary though. Some only have turbochargers and wouldn't run on low RPMs, they have no need to. Others, like the old Wichmann engines, have an 'auxiliary blower' that actually cuts out once the engine spools up the turbo sufficiently.
Happy days, I think they were also known as the Commer Cob for some reason. Unique noise for sure. I knew a fella that put one in an old Bentley all too long ago!
I remember travelling on the two Freighter Lawton Monobuses operated by North Road Bus Lines in Melbourne Australia . A very memorable sound was the TS3 under load ; amazing ; in my opinion , a great little diesel engine … very underrated . These buses were only manufactured in Melbourne by ‘ Freighters’ using parts from the Rootes Group . Not many built ; from reports , only about 40 . A very unique vehicle in it’s time . …. Peter , Melbourne , Australia
Sounds like my new Briggs & Stratton Personnel Pace Vortec Engine lawn mower. No oil changes required because it's designed to burn oil. It provides more power for the CC but still makes me anxious.
Ahh,,, I remember that very destinctive sound. The Shell trucks were all Commers in the 60s and 70s. I remember the blower sticking out at the front..Full load on board,The sound....Like a v12 with a leaking exhaust...

Drove one many........ many years back, WOW And yet what get out of a 3.2 or 200 cu inch motor these days...............crazy nothing like the sound of a knocker
@Abreen11 Seems a good idea on the face of it but I'm still unconvinced by the amount of moving parts - piston rod to rocker arm, conrod from rocker arm to crankshaft? A lot of linkage and moving parts between the combustion and the motion to my eyes. But hey, if it works.. The coolness factor is completely undeniable either way. I want one. Or ten.
@@jmoore9806 the pistons on this engine move toward each other. www.enginebuildermag.com/2014/10/ferraris-flat-twelve-dyno/ Not sure why the link reads Ferrari flat 12 but this article shows the operation of the Opposed Piston design.
Yes indeed it is BUT it's hard to do in practice at a sensible size and weight - which is why it isn't done on 2-stroke motorcycles. I personally have built some test engines and dyno tested them to silly outputs (17+ hp from a Briggs & Stratton 2-stroke mower engine 4HP as standard), BUT this was produced at 4750 RPM, with only about half that available 500 RPM above or below that speed, and less than the standard output 1000 RPM above or below. Never got around to building a variable pipe. :(
Does someone know for certain - were the pistons connected to a single crankshaft by duplicated con rods and rocker arms, or were there two separate "normal" crankshafts geared together?
@joffeloff I, too, am very interested in this design. I've been dreaming about designing a new version with 3 or 6 cylinders with modern high-tech materials, such as making the block and everything out of metal matrix composites (alloys with ceramics in them, ultra-hard and durable), using modern high-pressure rail direct injection - then compound charging the whole thing, with a variable geometry turbo feeding an Eaton TVS supercharger multiplying the boost! Happy dreams. :)
My brotherinlaw was a fitter/lorry driver he all ways carried ladies tights with him when driving a commer 2 stroke as he said it was easier to fit tights in place of a fan belt if it broke if the fan belt broke
What about a variable pipe exhaust, is this possible? The length or diameter can vary at different RPM, depending on what's needed. If you need high torque at low RPM, it can be one length and this can change throughout the rev range.
Is that compressor a Wade RO34? I know it's not being used as a supercharger, as you can't supercharge a two-stroke (It's being used to provide compression and scavenging), but I've seen these on hot rods as one.
I don't know how exactly the geometry or timing of the ports works, though. If the exhaust port side piston doesn't close the exhaust ports at least slightly before the intake side piston closes the intake ports, any kind of overcharge pressure would unfortunately be impossible. :( It is my understanding that the pistons are in fact not completely synchronized and at one point in the cycle move in the same direction, so perhaps there is a chance?
The AEC Militant 10 ton truck GS or /tractor 16 ton artillery was the only vehicle ever known as the knocker the Commer 2 strokes were known as screamers
Yes it's a nice construction. And at so low revolutions it should have low specific consumption. Well thats all in thanks to it being two-stroker and having oposed pistons I guess. What it needs is a turbocharger to upgrade the efficiency even more. I'd actually like to buy one of these engines someday and turbocharge it, add a transaxle and build a lightweight diesel sportscar.

Yep. Made by Rootes Motors Limited, but don't ask me where. The pistons are attached to a single crankshaft through a series of large rockers. Injection is done right in the middle. A few American companies, most notably Auto Diesel, made very similar truck engines but none were commercially successful. They were also sold through Lister-Blackstone as industrial/marine engines. Rootes made these engines from 1954 until 1968 when Chrysler took over the company.
It's amazing how evocative a sound can be. Not having heard it for over 40 years it brings back memories of commer trucks going through my childhood villsge.

A few American companies, most notably Auto Diesel, made very similar truck engines but none were commercially successful. They were also sold through Lister-Blackstone as industrial/marine engines. Rootes made these engines from 1954 until 1968 when Chrysler took over the company.
@@douro20 sounds like it was designed by a madman. but history shows that the world pivots on those who were considered mad.
