A modified form of apparatus is disclosed, and the preferred and illustrated embodiment thereof utilizes a pulse width modulator circuit to control the duty cycle pulses applied to coils for rotating an engine. The pulse width modulator (PWM) cooperates with an engine distributor system to generate a procession of pulses which are in turn applied to a power transistor to switch the transistor off and on in timed sequence. This applies power to coils for a magnetic engine. Moreover, two coils are included with each piston and are therefore able to be triggered at different intervals. A modified construction is also disclosed including a pair of coils which are serially positioned but independently connected to cooperate with a sleeve and piston telescoped therein and suitable passages for cooling water are also included.
