A Home Made V12 Solenoid Engine, Built Using Recycled Materials

A solenoid engine uses the magnetic pull of solenoids to turn a crankshaft, and resembles the architecture of an internal combustion engine./davidrobert2007

The crankshaft on this engine is made up of one hundred and forty individual parts bolted together, and is fully counterweighted to balance the rotational mass.//read more: davidrobert2007

The flywheel is an old drill / lathe chuck of some sort (army surplus), the engine has a tachometer pulse generator on the rear of the timing / distributor shaft to run the red LED tachometer, it uses Meccano timing chain and sprockets, and has a key ignition switch for added style.

This engine can run both as a four stroke or as a two stroke, and can switch while running. 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.
