Abstract

An internal combustion engine has a combustion chamber, an intake tract through which air can flow, a first tank for a liquid spark-ignition fuel, a second tank for water, a mixing region, in which the spark-ignition fuel from the first tank is to be mixed with the water from the second tank thereby creating a mixture having the spark-ignition fuel and the water, an injection valve which is allocated to the combustion chamber and by which the mixture can be injected directly into the combustion chamber, and a second injection valve which is allocated to the combustion chamber and provided in addition to the injection valve and by which in relation to the water and the spark-injection fuel, only the spark-injection fuel from the first tank can be injected at a location upstream of the combustion chamber into the intake tract and thus into the air flowing through the intake tract.
