More information:
A solenoid engine uses the magnetic pull of solenoids to turn a crankshaft, and resembles the architecture of an internal combustion engine. The crankshaft on this engine was built using Meccano discs, 4mm brass rod and various m4 nuts and bolts, and is counterweighted to balance the rotational and reciprocating mass. The engine uses Meccano timing chain and sprockets, and was originally designed as a four stroke but later converted to two stroke. The engine can still run as a four stroke, simply by swapping the timing gear to a 2:1 ratio and re timing the camshaft. This engine does not develop much torque, certainly much less torque than a standard rotary electric motor can produce, for the equivalent power input – for this reason the solenoid engine is just a novelty and an educational model.

I built this engine for fun, from mainly scrap metal and wood, and using mostly hand tools, and a cordless electric drill, during summer and autumn of 2012.
