A free-piston linear generator wherein the piston is a magnet propelled into reciprocating motion inside a non-conducting cylinder around which is wrapped one or more induction coils. The magnet-piston may be propelled into motion using either internal combustion of a diesel aerosol in a two-stroke or 4-stroke configuration, with ignition provided by compression, or by steam pressure provided by an external boiler. Sensor-controlled exhaust, fuel-intake, and air-intake valves are located at either end of the cylinder, although only a single intake valve would be required in a steam version. As the magnet-piston moves in the cylinder, the power stroke on one side of the magnet-piston is the compression stroke on the other side. The movement of the magnet-piston induces an electric current in the induction coil, by which energy is drawn from the engine as useful work.

An internal combustion engine that uses stratification of gasses for compressing air is disclosed. The engine uses a combustion chamber that delivers products of combustion into an elongated compression chamber to drive the products of combustion against resident air within the elongated compression chamber, and push the resident air into a compressed air chamber. After driving the resident air into the compressed air chamber, the products of combustion are used with work-producing devices. Air is then driven into the compression chamber by an air pump or low-pressure compressor to once again fill the compression chamber with fresh air. The air in the compressed air chamber is then delivered to the combustion chamber and used for combustion. Fuel is delivered to the combustion chamber by a fuel injector, and ignited by the heat of the compressed air and/or a glow plug, spark plug, or similar ignition device.

A device for the repeated production of explosions includes an explosion space, a feed conduit for feeding a flowable, explosive material, a discharge opening for the directed discharge of a gas pressure produced by the ignition of the explosive material in the explosion space, and a movable closure element for the partial or complete closure of the discharge opening. The device includes an exit nozzle with a nozzle entry area and a nozzle exit area, as well as an actuation device. The actuation device is adapted, after an opening of the discharge opening and an outflow of explosion gases through the exit nozzle, to adjust an area ratio between the nozzle entry area and the nozzle exit area. The area ratio at least approximately follows an ideal area ratio for the production of a maximal exit speed of the explosion gases, in dependence on the pressure in the explosion space.

This invention provides a coil and magnet assembly that is operatively interconnected with an oscillating free piston that moves along an axis. A coil mounting disk is operatively connected to a coil assembly. A magnet assembly is mounted on a magnet base. The magnet assembly is coaxial with respect to the coil assembly. The coil assembly and the magnet assembly are in oscillating motion with respect to each other in conjunction with oscillating motion of the free piston. A spring assembly comprising a plurality springs, symmetrically positioned about the axis, extend between the magnet base and the coil mounting disk, so as to move in conjunction with the oscillating motion along the axis. At least some of the springs are conductive and electrically connect the mounting disk to the magnet base. The piston can reside in a casing that is part of either a two-stroke engine or a fluid pump.
