The idea behind the 45° V-Twin with a 4-stroke action was to create a Harley-Davidson like sound from a solenoid motor.The idea is very simple: It is a “similar-to-combustion-engine”, but powered by electricity instead of fuel.

A crank shaft is put to run by the action of a set of reciprocating electromagnetic solenoids, instead of a set of valves and pistons.They can be made out of any number of “cylinders” (solenoids), likewise any kind of combustion engine.
Each cylinder fits to one of these steel frames and the crank boss goes through the 2 frames at the bottom, this allowed me to stagger the frames and so give the necessary offset for each cylinder centre, needed for a single pin big end.
From the rear of the engine you can see the single pin.The crank is nearly at bottom dead centre and so both pistons for the solenoids are out of the bottom of the coils.The power to the engine is provided by 4mm banana plugs and the engine needs a good 12V 2.5A power supply to run well.
