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.
An internal combustion process wherein combustion-supporting air is compressed outside of a working cylinder-piston and compressed air and a gaseous fuel are supplied separately in predetermined quantities to a burner nozzle and mixed therein and ignited and burnt without increasing the pressure in the cylinder-piston and wherein the energy of the combustion gases which expand without cooling is transmitted to the working piston and the exhaust gases are removed from the working cylinder, characterized in that the combustion-supporting air is compressed substantially isothermally then heated by the hot exhaust gases with some of the compressed hot air being diverted to preheat and carburet and compress the fuel with the remainder of the combustion-supporting air and the combustible gas evolved being burnt substantially stoichiometrically by self-ignition.
An internal combustion engine in which a combustible gas and a combustion-supporting air are supplied precompressed to a cylinder-piston by separate channels and at least one controlled burner nozzle, the mixture formed in the burner nozzle being burnt in the cylinder-piston without substantial pressure increase, characterized by a separate air compressor for providing substantially isothermal compression of the combustion-supporting air;
