Opposed piston 2 stroke diesel may very well replace conventional 4 stroke diesels Opposed piston engines can be extremely efficient

@@hopingforthebest1.9 Yes just not Commer Knockers.

@@ThePaulv12 yeah the main reasons for the design aren't problems anymore... and the achates design that runs similarly is more likely to get implemented. The commer knocker avoided having 2 cranks and gearing that you can get away with on modern engines.

Full chat . Not heard that saying for a long time!

@@paulnicholls8683 yes, well, I'm an old geezer. Lol. Actually, it was a term used by one of my tutors when an engineering apprentice. He used to say" let's see it running at full chat first". He taught us how to hand scrape bronze bearings. He was a bloody good bloke, now long passed.

Thank you mate, more to come!

Agreed! glorious sound out of an engine from a Leyland truck.

How true soon as they lose a few revs like in this video they quickly lose pulling power.

They were a very noisy engine too if I remember correctly. Much favoured as a marine engine and can still be reconditioned by a guy in Manukau city. Needed to be maintained to a high standard as timing chains and super chargers wear out quickly.

You must know about the ts4 then, the engine that chrysler got rid of because they wanted the useless Cummins yale engines instead.

@@edwardkennedy9919 i have seen the ts4 prototype in the leyland transport museum

@@grumpystruckshop3807 yeah there is a video on KZfaq with a ts4 it sounds awesome,

Philip Nash. Knew Tilling and Steven's well. Grew up just outside Maidstone where their works were. Saw a good many of their Trojans too.

That's not noise - that's Commer TS music!

Exactly poor thing

I agree - they have a real throaty burble and rumble. I have been told that the pipes glow bright at night because TS works so hard.

Knocker was an Aussie name for the TS3 as the Aus/NZ variant had a different compresser on the blower with no dampener, which used to knock at idle, hence Commer Knocker. They were great engines with wonderful torque though. No need for the 10 speed transmissions of comparable trucks with diff splitters.

@@PaulBKal Depends on the application.... a 671 detroit doesn't need a splitter in a 25k lb bus even with just a 4 speed, but it would need one on a 50k semi or dump truck.

Actually an opposed piston engine. A horizontally opposed engine would be like a Porsche 911 with cylinders on either side of a central crankshaft, whereas an opposed piston engine has 2 pistons sharing the same cylinder. Most opposed piston engines have a crankshaft on each end, however the TS3 has a single crankshaft below the pistons, and the pistons are driven via giant rocker arms.

It wasn’t loaded though was it 🤷‍♂️

Die Amis denken immer, daß sie alles besser wissen und auch können! Der Größenwahn ist nicht zu toppen!

yep lower revs more stress, + engine driven oil pump=less oil circulation, stay in high end of torque band

nonsense, they were wonderful torquey motors that held their revs well. All you achieved with an unnecessary downchange was slower speed.

I wondered that too. I know when I lived in England and rode 2 sroke motorbikes we kept the engine screaming

I drove these back in the day and they were not high revving diesels that needed the revs kept up at all costs, for example like a Cummins V8 504 or 555. They might have sounded like they were screaming but there were wonderful high torque diesels that lugged like the proper diesels they were. No one who has ever driven one would have done anything different to what these guys did. Holding your gear meant maintaining speed and using the torque of the engine. It’s how you drive a diesel.

Calling someone an idiot for not keeping the RPM up when you don't know these engines make peak torque at 1200 RPM...

Get a wheelchair !!!☻☻
