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 ...

In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single opposed-piston engine. This unique project improves balance, reduces vibrations ...
