摘要： In a control unit, a method, a computer program and a computer program product for operating an internal combustion engine in the context of a combined direct and manifold injection, fuel is injected by at least one first injection valve into an induction manifold and/or by at least one second injection valve directly into a combustion chamber for combustion. In at least one predefined operating state of the internal combustion engine, fuel is only injected by the at least one first injection valve into the induction manifold for a predetermined number of successive combustion cycles. In a subsequent combustion cycle, fuel is injected by the at least one first injection valve into the induction manifold and by the at least one second injection valve directly into the combustion chamber or only by the at least one second injection valve directly into the combustion chamber.

摘要： A method and a device for operating an internal combustion engine and an internal combustion engine are described, the fuel being injectable directly into a combustion chamber in particular via at least one first injector and also being injectable into an intake manifold in particular via at least one second injector. For injection of fuel in a full-load operating state of the internal combustion engine, a first selection is made from the at least one first injector and the at least one second injector having a first metering range, including a full-load injection quantity required for the full-load operating state. For injection of fuel in a partial-load operating state of the internal combustion engine, a second selection is made from the at least one first injector and the at least one second injector having a second metering range, including the adjustment of a minimum fuel injection quantity required for operating the internal combustion engine. The first selection and the second selection are made differently, in such a way that only the metering range of the first selection includes the full-load injection quantity and/or that only the metering range of the second selection covers the minimum fuel injection quantity required for operating the internal combustion engine.

摘要： A method and a device for operating an internal combustion engine to perform a lambda regulation without using a lambda sensor. Fuel is injected for combustion in a combustion chamber of the internal combustion engine. A first quantity of the internal combustion engine is ascertained, which allows a conclusion to be drawn about the behavior of an output quantity of the internal combustion engine, in particular of a torque. The method includes the following: a) a first fuel quantity to be injected is predefined; b) a first value of the first quantity is ascertained, which results from a fuel injection according to the first fuel quantity to be injected; c) the fuel quantity to be injected is modified from the first fuel quantity to be injected in relation to an air quantity to be supplied to the internal combustion engine (1); d) a second value of the first quantity, which results from the change in the fuel quantity to be injected, is ascertained; e) the first value of the first quantity is compared to the second value of the first quantity, and f) as a function of the comparison result, a value for an air/fuel mixture ratio for the first fuel quantity to be injected prevailing prior to the change in the fuel quantity to be injected is ascertained independently of a measured value of a sensor measuring the oxygen level in the exhaust gas.
