A piston/cylinder internal combustion unit has opposed pistons connected to a common rod and driven in an oscillatory and reciprocating movement. The pistons operate out of phase with each other, such that the power stroke of one drives the compression stroke of the other, and a spring acts on the rod storing energy or exerting a restorative force as the rod is displaced with piston movement. Preferably, the moving rod carries a coil assembly near a stationary magnet (or a magnet near a stationary coil assembly) to produce electricity at the oscillatory frequency. The engine may employ a mechanical spring, an electromagnetic or a magnetic spring, or combinations thereof to stabilize or establish oscillation of the piston and rod assembly. The coil itself may fill this function and act to exert restoring force by coupling to an external control system that applies a control a signal to the coil in accordance with piston position to create an electromagnetic restoring force of appropriate level. The piston rod may couple to a first coil that acts as a spring, and a second coil that functions as an alternator to generate power. By driving the pistons in opposite phase, or by providing a magnetic/electromagnetic spring mechanism, a higher constant k is achieved, raising the frequency of oscillation and increasing power output of the engine.

An internal combustion engine comprising first and second pistons, a connecting rod interconnecting the first and second pistons, and at least one spring assembly having a double helix configuration coupled to the connecting rod, the spring and opposed pistons being opposed and operating alternately providing restoring force for oscillating movement of the connecting rod along a linear axis, the rod carrying a coil for reciprocating travel in a magnetic field such that energy is efficiently extracted from the moving assembly as the pistons are driven by internal combustion. 3. An internal combustion engine having a first piston and a second piston, the first and second pistons being attached to opposite ends of a single piston rod, and a plural spring assembly coupled to the rod so as to cancel rotational force components and to maintain an oscillating movement of the mass comprising said pistons and said single piston rod as the pistons are driven by forces of combustion. 4. The internal combustion engine of claim 3, further comprising a coil assembly and a magnet assembly at least one of said coil and said magnet assembly being carried by the piston rod to provide relative reciprocating movement between the coil assembly and the magnet assembly to thereby generate electrical energy.
