Abstract
A method of and an arrangement for burning a liquid or gaseous fuel in a combustion chamber of an internal combustion engine. A method of and an arrangement for burning a liquid or gaseous fuel in the presence of air or another oxidant and by the use of water in a combustion chamber (12) of an internal combustion engine, especially a reciprocating or rotary piston-type engine. To reduce the fuel consumption and the emission of harmful substances and to increase the efficiency when low-octane fuels, especially regular gasoline or acetylene, are used, water is injected during one or several selected phases, in particular during the entire operation, in an operation-dependent quantity direct into the combustion chamber (12) in such a way that a progressive "primary combustion" of fuel/air just below the critical "knock" temperature (T.sub.c) occurs which initiates a "secondary combustion" of the admixed water at any point of combustion. The "secondary combustion" causes overall smooth progressive combustion within the combustion chamber (12).
