Rotary Piston Engine with Solid Particle Fuel Capability

Abstract

Axially protruding and centrally cool able pistons rotate within a cylindrical main chamber. Each piston is individually kinetically linked to a flywheel. As the pistons are individually accelerated and decelerated along their continuous rotating path, rotating volumes between them angularly expand and contract. Such rotating piston mechanism may be part of compression and/or expansion stages of a combustions engine system that may further feature a combustion system and/or a particle fuel evaporator in between them in which solid fuel particles are heated such that their evaporable portion evaporates to be used as engine fuel. Absence of valves and self cleaning centrifugal effects in the rotating volumes of the compression and/or expansion stages are thereby advantageously utilized to combust solid particle fuel and/or their evaporating content with low risk of particle clogging or built up. Remaining carbon particles may be extracted from the combustion engine via a carbon particle extraction port.
