Method for injecting an additional medium into the cylinder of a spark-ignited internal combustion engine and internal combustion engine for carrying out such a method

摘要

The invention relates to a method for directly injecting an additional medium into the at least one cylinder of a spark-ignited internal combustion engine, wherein the additional medium differs from an introduced for operation of the internal combustion engine fuel and the additional medium is injected to reduce a knocking combustion. It should be shown a method that is improved in terms of the injection of the additional medium. This is achieved with a method of the abovementioned type, which is characterized in that for an operating cycle injected into a cylinder mcoolant amount of additional medium and a per working cycle introduced into the cylinder fuel quantity mfuel applies: mwater ≤ 0.2 mfuel.
