What it has developed is an opposed-piston, two-cycle, compression-ignition engine. “It’s cleaner, more efficient [and lower cost]… than anything else on the market,” said Johnson ...

Basically the engine is two opposed pistons pushing each other back and forth. One past use of the design was as an air compressor where each piston was connected to a compressor cylinder.

The free piston engine, a design with opposed pistons working against compressed air springs and combining both compression and firing strokes in a single axis, doesn’t turn anything in itself ...

While most engines made in the last 100 years have adhered to the standard single-piston per-cylinder design, the TS3, also known as the "Commer Knocker," is an exception. The opposed-piston ...
