摘要： In a method for operating an internal combustion engine, a setpoint fuel quantity to be injected is subdivided into a first fuel quantity which is to be injected into an intake manifold of the internal combustion engine, and a second fuel quantity to be injected directly into a combustion chamber of the internal combustion engine. The subdivision of the fuel quantity is performed as a function of a temperature that is characteristic for the operation of the internal combustion engine, e.g., in a start of the internal combustion engine, and the ratio between the first fuel quantity and the second fuel quantity is continually modified as a function of the temperature.

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： In a method for operating a valve, e.g., a fuel injector of an internal combustion engine in a motor vehicle which is activated with the aid of an actuator, the actuator is activated using a control variable which has a predetermined control period. The control period is formed as a function of a setpoint value for a closing delay time of the valve which characterizes a time difference between an end of the control period and a closing point in time of the valve.

摘要： With a method for operating an internal combustion engine with a fuel injector (18) that is opened and closed electrically, a booster capacitor (BK) serving to increase the current intensity when the fuel injector (18) is opened, reliable fuel injection is ensured, even in extreme cases, such as resumption of fuel injection after an overrun condition, and in a starting procedure after a shutoff phase that is accompanied by an increase in pressure in the high pressure fuel system due to the fuel heating up, when booster capacitors are used that were designed for normal operation, by switching the current profile in certain operating states of the internal combustion engine from a standard value to an increased value and/or to a longer duration and, when the certain operating state ends, by resetting it to the standard value and the standard duration.
