Abstract: A valve assembly for an internal combustion engine includes a stationary permanent magnet assembly having at least one permanent magnet for generating a permanent magnetic field with a radial component and a movable coil assembly having at least one coil of electrically conductive material for generating a magnetic field with an axial component that intersects the radial component when an electrical current is applied to the at least one coil to thereby move the coil assembly with respect to the permanent magnet assembly. A valve is connected to the coil assembly for movement therewith. Electronic control of the valve assembly together with engine modifications permits the engine to dynamically switch between two-cycle and four-cycle modes of operation.

Abstract: An exhaust gases purification device for internal combustion engines, of the kind that includes a duct which channels gases from the engine exhaust manifold, and injects them into the device. The device includes a quiet chamber, wherein gases expand, a first standard filter, a buffer plate, then a second filter, and then a centralizer-diffuser assembly where the gas flow is contacted with two external cold air drafts and part of the polluting gases are channeled into a turbulent chamber, from which they are fed into the engine as intake gases. The remaining flow is discharged into an tube ending in a atomizer, and from there into an exhaust tube. The turbulent chamber includes an engine port portion that discharges into fixed buckets, where gases are expanded and channeled into the atomizer that contains a gas recovery outlet back into the engine.
