The “D-cycle” and the “Diesoline” Retrofit Hybrid Engines

Simply splitting the piston crown from the skirt (Fig. 1) to pump gases for the combustion chamber via a (valvetrain-like) “piston-train” and then combining to turn the crank” makes a 2-/4-cycle hybrid, called “D-Cycle” (Differential-Stroke-Cycle) engine.

A Propellantless Thruster Based on Lenz's Law

The EM Sektet Thruster is a novel propellantless electromechanical propulsion system that generates net thrust by exploiting the principles of electromagnetic induction—specifically Lenz’s Law—in a way that transfers momentum internally within the system. Unlike conventional propulsion systems, which require the ejection of mass (propellant) to generate thrust in accordance with Newton’s Third Law,
