Abstract: In a two-stroke internal combustion engine with a crank slide mechanism and a plurality of working cylinders which, have bases and are divided by a piston into a lower and an upper cylinder chamber, the lower cylinder chamber being used substantially for compression and the upper cylinder chamber being used substantially for combustion, storage cylinders are provided which can be connected to cavities such as working cylinders of the engine and processing chambers such that each adjoining cavity has at least one closable inlet opening through which an air-fuel mixture, e.g. can flow from the storage cylinder into the cavity and at least one closable outlet opening through which the mixture can flow out of the cavity into the storage chamber.

Abstract: A method for generating, from refuse or refuse in combination with coal, a fuel gas suited for public utility purposes wherein refuse and coal can be introduced into the process in any proportion one to the other. The method provides the steps of subjecting the refuse to allothermal low-temperature carbonization, if desired in combination with coal, burning the gasification residue, purifying the crude gas and conditioning the pure gas for public utility purposes.
