There are two-stroke diseel trucks. The Commer TS-3 was two-stroke.

You seem to have a problem with are and was. Commer went out of business
in 1979.

The Commer two stroke opposed piston engine is well worth checking
out - it's quite amusing.

Especially the way that the supercharger was driven off the
crankshaft by a differential gear arrangement which meant that the
harder it worked, the higher the boost pressure got. Three cylinders,
six pistons, two crankshafts...

ONE crankshaft. It had rockers.

Was that without the mods?
