What's old is new again: the opposed piston engine

[CREEPING DEATH]

I'm really curious how you'd time an opposed-piston four-stroke-cycle engine!
If you want to learn about a single-crankshaft opposed-piston engine, google "Commer Knocker".

The American auto builder Kelvinator/Nash built a protype boxer engine intended for their International (later Metropolitian) model. It was a six cylinder, water cooled, L head arraingement with two rows of three cylinders. There is a picture of it in a book featuring the Nash Metropolitan, which is about as far as one can get from locos and subs!

This tread is not about "boxer" engines...

Sorry to resurrect an old thread, but obviously no older Pommy members on this site, or they would have brought up the Commer double knocker truck engine, which was also popular in Australia and South Africa in the 50's and 60's, a unique sound
