A method () is proposed for operating an internal combustion engine (), which comprises a lean-burn engine having compression-ignition, having a throttle valve () in an air path () upstream of the internal combustion engine () and an exhaust gas posttreatment system () downstream of the internal combustion engine (), comprising a control of the internal combustion engine () according to a present load demand () using metering of an amount of fuel in dependence on the present load demand; and if a load demand () is absent in a heating operating mode, further comprising partially closing () the throttle valve () and defining a minimum value for the amount of fuel, which is greater than zero. Furthermore, a computing unit and a computer program for carrying out such a method () are proposed.

Method, computing unit, and computer program for operating an internal combustion engine

For an optimized metering of fuel and water for the operation of an internal combustion engine in which a direct injection and an intake manifold injection are provided for metering fuel into the internal combustion engine, and in which the internal combustion engine is assigned a system for water injection, a same intake manifold injector is used for both water and fuel injection.

Fuel metering for the operation of an internal combustion engine

In a method for operating an internal combustion engine with intake manifold injection and direct injection, a value of at least one parameter that is correlated with an exhaust gas of a combustion chamber of the internal combustion engine and that is influenced by purging of uncombusted fuel through the combustion chamber into the exhaust gas is ascertained, and, if it is concluded, based on the ascertained value of the at least one parameter, that uncombusted fuel is purged, at least one operating parameter for filling the combustion chamber is adjusted.

Method for operating an internal combustion engine

A method for implementing a communication between at least two control units, and a control unit interconnection for implementing the method are provided. An electronic hardware security module is provided in each control unit, the communication taking place via an additional communications link.

Method for implementing a communication between control units

A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized. In the second testing, the main computer is tested by performing a test instruction on the slave computer, when the main computer is initialized. In the forwarding, the surroundings data are forwarded via the communication interface by performing the communication instruction on the slave computer, when the main computer is tested.
