1. A method for performing mechanical work, in which energy for operation is obtained from oxidation of carbonaceous fuel in an internal combustion engine, comprising:
- said carbonaceous fuel, oxygen-enriched air or pure oxygen, and water are brought into at least one combustion chamber of said internal combustion engine, wherein the water is fed directly into the at least one combustion chamber,the carbonaceous fuel is combusted to form an exhaust gas,a resulting exhaust gas pressure or exhaust gas volume is converted into mechanical work, andexhaust gases resulting from said combustion of said carbonaceous fuel, the exhaust gases consisting essentially of carbon dioxide and water, are compressed and/or condensed, and captured in a storage means; and
wherein the method further comprises a step of manufacturing the carbonaceous fuel, prior to bringing said carbonaceous fuel into the at least one combustion chamber, by a method for the thermo-chemical utilisation of carbonaceous starting materials, in whichin a first stage the carbonaceous starting materials are pyrolysed and pyrolytic coke and pyrolytic gas result;
in a second stage the pyrolytic coke from the first stage is gasified and synthesis gas results, and slag and other residual substances remain and are led away; and
in a third stage the synthesis gas from the second stage is converted into said carbonaceous fuel;
wherein said carbonaceous fuel consists of hydrocarbons or hydrocarbon derivatives, andwherein excess recycle gas from the third stage is led into the first stage and/or the second stage, and the three stages form a closed cycle.

Abstract
A device (1) for performing mechanical work and/or producing electrical or thermal energy, the energy necessary for operation is obtained from the oxidation of carbonaceous fuels (20) into carbon dioxide (24) and water (23). The device comprises means (14) for compression and/or condensation of the exhaust gas (21), and storage means (15) for receiving the compressed and/or condensed exhaust gas (21).

-
said carbonaceous fuel, oxygen-enriched air or pure oxygen, and water are brought into at least one combustion chamber of said internal combustion engine, wherein the water is fed directly into the at least one combustion chamber, the carbonaceous fuel is combusted to form an exhaust gas, a resulting exhaust gas pressure or exhaust gas volume is converted into mechanical work, and exhaust gases resulting from said combustion of said carbonaceous fuel, the exhaust gases consisting essentially of carbon dioxide and water, are compressed and/or condensed, and captured in a storage means; wherein at least a part of said exhaust gases resulting from said combustion of carbonaceous fuel is utilised in a method for the thermo-chemical utilisation of carbonaceous starting materials, in which in a first stage the carbonaceous starting materials are pyrolysed and pyrolytic coke and pyrolytic gas results; in a second stage the pyrolytic coke from the first stage is gasified and synthesis gas results, and slag and other residual substances remain and are led away; and in a third stage, the synthesis gas from the second stage is converted into further carbonaceous fuel; wherein said further carbonaceous fuel consists of hydrocarbons or hydrocarbon derivatives, and wherein excess recycle gas from the third stage is led into the first stage and/or the second stage, and the three stages form a closed cycle; and wherein the exhaust gases are fed into the first stage, and/or second stage and/or third stage. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
