Abstract:
A method and control unit for metering fuel into at least one combustion chamber of an internal combustion engine comprising at least one pilot injection and one main injection per combustion cycle, combustion features being detected and an effect of a fuel quantity injected prior to the main injection being ascertained from the combustion features. An actual value of a combined effect of at least two pilot injections per combustion cycle is ascertained and the actual value is regulated to a setpoint value via an intervention on at least one of the pilot injections.
