Publication number: 20240125281Abstract: Various embodiments of the present disclosure are directed towards free-piston combustion engines. As described herein, a method and system are provided for displacing a free-piston assembly to achieve a desired engine performance by repeatedly determining position-force trajectories over the course of a propagation path and effecting the displacement of the free-piston assembly based, at least in part, on the position-force trajectory. In a dual-piston assembly free-piston engine, synchronization of the two piston assemblies is provided.Type: ApplicationFiled: July 5, 2023Publication date: April 18, 2024Inventors: Matthew Roelle, Christopher Gadda

Patent number: 11867116Abstract: Various embodiments of the present disclosure are directed towards free-piston combustion engines. As described herein, a driver section may be provided in a free-piston combustion engine for storing energy during an expansion stroke. The driver section may be configured to store sufficient energy to perform the subsequent stroke. In some embodiments, the driver section may be configured to store sufficient energy so as to enable the engine to operate continuously across engine cycles without electrical energy input. A linear electromagnetic machine may be provided in a free-piston combustion engine for converting the kinetic energy of a piston assembly into electrical energy.Type: GrantFiled: February 13, 2023Date of Patent: January 9, 2024Assignee: MAINSPRING ENERGY, INC.Inventors: Christopher Gadda, Matthew Roelle, Adam Simpson
