Date Jun. 19, 1986.A method of and an arrangement for burning a liquid or gaseous fuel in the presence of air or another oxidizer and by use of water in a combustion chamber (12) of an internal combustion engine, especially a reciprocating or rotary piston engine. During one or more selected phases, especially during the entire operation, prior to being introduced into the combustion chamber (12), the fuel is mixed intensively with air and a quantity of water which depends on the operation in order to reduce the fuel consumption and the emission of noxious components as well as to increase the efficiency when using low octane fuels, especially regular gasoline or acetylene as the fuel. The mixing takes place in a quasi-closed mixing chamber (22) in the intake passage (11). Upon compression and ignition of the fuel/air/water mixture in the combustion chamber (12) a progressing "primary combustion" of fuel/air is controlled just below the critical "detonation" temperature (Tc), which combustion gives rise to "secondary combustion" of the admixed water at every location of the combustion. The "secondary combustion" causes an overall smooth, progressing combustion within the combustion chamber (12).
