We explored the Commer TS3 recently.

The Commer was weird, but it wasn’t the only two stroke engine used in British trucks in the 1950s and 60s. There was also the Foden FD6, sadly a conventional engine with just the one piston per cylinder.

Want to know what it was like?

What’s he doing with the lever beside the wheel? It’s for the three speed auxiliary box (low, direct, overdrive) which worked with a four speed main box to provide eleven usable gears (and one impractical one).

If you used all the gears you’d start with your auxiliary in low, change from first to third on the main box, then auxiliary to direct and main back to first and from there on you went 1 direct, 1 overdrive, 2 direct, 2 overdrive and so on so lots of hissing noises from the pneumatically operated auxiliary. Like other diesel two strokes you had to rev it furiously to make any progress. It was said of diesel two strokes that their main achievement was to convert diesel to noise.

Of course, in the DDR, one had two-stroke gasoline trucks, of a Wartburg-powered nature. This being a locksmith’s truck is somewhat perverse - wouldn’t you want someone to hurry if you’d been locked out?

I doubt if they were that slow though by the standards of the time!

We had two stroke buses once. They went well enough but had a rather poor noise to fuel consumption ratio and were replaced with proper DAF and Volvo four strokes.

Compared with the Standard Atlas in its early versions with a sub 1L engine, a Barkas may well fly. No smaller an engine, and in two-stroke for some improvement in output.
