As you may know Mr Carryfast has some strange veiws and wont back down but is good value for a laugh.
You may know about his fondness for two stroke detroit diesel engines. Well according to this months trucking magazine the two stroke diesel could be the answer to the truck makers future problems of producing cleaner more efficent truck engines.
Sadly not as a conventional in line or v configuration like detroit use but a horizontaly opposed piston design like the commer design from the 50s and 60s.
Just shows how advanced british enginering is we was just about 50 years too early.
Is that the modular engine they’re going on about? I saw something about it being stackable, I haven’t seen any pics of it, but I imagine it’s a boxer layout, as in the old Rootes engines you describe, a couple of them welded together, now that would put those V8 Scania boys in their place in the lorry park symphony 
As daft as it is, engineering principles haven’t evolved far, tolerances are much closer giving better performance and longevity, but a blower is nothing new, gas powered vehicles were used in the war, steam is still a powerful energy source and an electric motor was used on a 1910 tram.
When we ran two strokes we had to add oil, now we add AdBlu! Hydraulic rams are old hat, but there is nothing to beat them, we will never see as much engineering skills in the next century.
The internal combustion engine was first developed in the 13th century but it was 1896 when they developed the Boxer engine.
We haven’t found much better yet. even the 4.5 Bentley Blower was putting out 240 horses in 1928

No oil needed to be mixed with the fuel in one of these or a Detroit though. 
Yeah it is a modular design in a boxer set up il look for the mag but think the mrs may have filed it in the recycling

There’s a big difference between an opposed piston set up ( Rootes or Deltic for example) and a boxer crank (Ferrari).

Yeah they’re the ones I’ve heard about, they’re touting them as having a really good power to weight ratio, it’s a flawed philosophy really, a couple of hundred kgs won’t make a lot of difference either way on a big truck, in a car a small weight saving can make a big difference.
Now, having said that, there’s a new fuel mileage thing that dear old Obama has introduced, he wants a 20% reduction in fuel consumption on future trucks, not a bad idea in theory, but as usual for any government nonsense, in practice it’s a waste of time. The fuel consumption will be an average figure over the whole range of trucks produced by any manufacturer, but it doesn’t take into account the fact that trucks are built to carry loads, so the mpg will be figured using a chassis cab only, so in that instance, light weight will make a difference, so Carryfast may once again hear the sound of a screaming two stroke, although they’ll probably be strangled with exhaust filters and such like so that they sound more like a Citroen 2CV 
Also, as a result of this new regulation, aerodynamics will be very important, so that’s the end of ‘proper’ American trucks

Just looked it is similar to the old commer type design according to the article
