Abstract: An apparatus for the production of combustible gas from waste materials and other combustible materials, in which the charge is dried, its combustible parts are subjected to low-temperature carbonization and the low-temperature carbonization gases are converted to combustible gas in a hot reaction bed. The charge is subjected to low-temperature carbonization at a temperature of from 300.degree. to 600.degree. C. with the exclusion of air, the resulting solid low-temperature carbonization residues are separated and the low-temperature carbonization gases are continuously drawn through a reaction bed at a temperature of from 1000.degree. to 1200.degree. C. formed from a solid carbon vehicle and a preheated fresh-air supply, and are converted to high-energy combustible gas in said reaction bed.

Abstract: An internal combustion process and engine in which the chemical energy of a fuel is converted into heat by timed combustion using self-ignition and into kinetic energy by expansion of the hot combustion gases and is transmitted by way of a piston to a shaft. The combustion-supporting air is compressed substantially isothermally, then heated by the hot exhaust gases. Some of the compressed hot air is diverted to preheat and carburet and/or compress a fuel and the remainder of the combustion-supporting air and the combustible gas evolved are supplied separately and in substantially stoichiometric quantities to a burner nozzle, mixed therein and burned by self-ignition with a reduced excess of air and without pressure increase. The energy of the combustion gases which expand without cooling is transmitted to a piston and the exhaust gases are removed from the cylinder chamber.
