摘要:
A method for controlling an injection of fuel in an internal combustion engine, in particular in a gasoline engine having direct injection, a drive fuel quantity, which indicates the fuel quantity required by the internal combustion engine to provide a torque, being injected in a working cycle before a combustion stroke of the working cycle into a cylinder of the internal combustion engine, a cooling fuel quantity, which indicates the fuel quantity which is used to cool the combustion exhaust gases, being injected in the working cycle in addition to the drive fuel quantity, at least part of the cooling fuel quantity being injected after completion of the combustion in the combustion stroke and/or the immediately following exhaust stroke of the working cycle.
