    Abstract: An internal combustion engine, in particular for a motor vehicle, is described. The internal combustion engine is provided with a control unit for determining a setpoint fuel mass and/or a setpoint air mass as a function of a setpoint torque. The control unit is also provided for transitioning from a first operating mode to a second operating mode of the internal combustion engine. An actual torque is determined by the control unit during the transition to the second operating mode of the internal combustion engine. A torque difference between the setpoint torque and the actual torque is also calculated by the control unit. Finally, the setpoint fuel mass and/or the setpoint air mass is controlled by the control unit as a function of the torque difference.

    Abstract: A control system for a fuel pump, particularly for a solenoid-valve-controlled fuel pump in the case of a self-ignitable internal-combustion engine, in which at least one pulse transmitter is mounted on the crankshaft and/or on the camshaft. The generated pulse sequences include at least several reference pulses for establishing the beginning of fuel injection, as well as speed pulses for detecting the average and the instantaneous rotational speeds. A trial activation takes place to detect into which cylinder the fuel must be injected. Based on the reaction of the fuel injection system and/or of the internal-combustion engine, it is detected whether fuel was injected into the proper cylinder.

    Abstract: In a method for indirectly ascertaining the cylinder pressure during the operation of piston engines by measuring cylinder pressure-dependent parameters at crankshaft bearings of the piston engine, one essential feature is that the force which is introduced by the main bearings of the crankshaft into an engine housing is measured. For performing the method, sensors for obtaining cylinder pressure-correlating signals are disposed on the bearing screws, and that the signals generated by the sensors are carried to the outside.

    Abstract: A method and a device for controlling an internal combustion engine. An actuator serves to influence the quantity of exhaust gas recirculated. A loop controller preselects the quantity of exhaust gas to be recirculated on the basis of a setpoint and an actual value which characterizes the quantity of exhaust gas recirculated. A first measured value is determined in a first position (open) of the actuator, and a second measured value is determined in a second position (closed) of the actuator, with the actual value or a correction value being preselectable on the basis of the difference between the two measured values.

    Abstract: A method and a device for correcting for tolerances in a transmitter wheel are described. The transmitter wheel has a plurality of approximately equidistant marks that are scanned by a pickup. The pickup supplies a pulse train on the basis of which measured values are formed, with correction values being determined on the basis of a comparison of the individual measured values with a reference value. The measured values are filtered with at least one first and one second frequency-selective filtering.
