  • Publication number: 20090211553
    Abstract: A method for metering fuel into a combustion chamber of an internal combustion engine is provided, in which a fuel quantity to be metered for a combustion is metered by a preinjection and at least one additional injection, and in which, in the operation of the internal combustion engine, quantity errors of the preinjection are ascertained from the signal of at least structure-borne noise sensor. The method is distinguished in that a correction value is formed as a function of the quantity error of the preinjection, and at least one of the additional injections is corrected using the correction value. A control device is also provided that controls the method.

  • Patent number: 7512478
    Abstract: To enable operation of an internal combustion engine even without the signals of a phase sensor while nonetheless enabling an emergency driving function in the case of a disturbance of a crankshaft signal acquired by a crankshaft sensor, a cylinder pressure is acquired using a cylinder pressure sensor and it is checked whether the cylinder pressure reaches a prespecifiable threshold value. When the threshold value is reached or exceeded, an angular position associated with the threshold value is inferred. The angular position is then made available for an operation of the internal combustion engine.

  • Publication number: 20080304196
    Abstract: An electrical circuit comprising a power supply, a load and an incendive arc prevention means comprising a monitoring means and an isolation means, in which the monitoring means monitors the electrical circuit by means of a reactor means, in which if a short circuit with the potential to cause an incendive arc occurs in the electrical circuit the reaction of the reactor means is detected by the monitoring means and the isolation means fully or partially isolates the power supply from said short circuit, such that an incendive arc cannot occur, in which if an event with a current and/or voltage pattern which is characteristic of a propagating non-incendive arc occurs in the electrical circuit between the power supply and the load, the reaction of the reactor means is detected by the monitoring means, and the isolation means fully or partially isolates the power supply from said event, such that an incendive arc cannot occur.

  • Patent number: 7421331
    Abstract: A method for operating an internal combustion engine, particularly of a motor vehicle. The internal combustion engine has a combustion chamber and an injection valve by which fuel is able to be supplied to the combustion chamber, directly or via an intake manifold. In the method, a maximum combustion chamber pressure and a signal for a start of the injection of fuel is determined, and the signal for the start of injection is influenced as a function of the maximum combustion chamber pressure. A signal for an injection duration of fuel is determined and influenced as a function of the maximum combustion chamber pressure.

  • Publication number: 20070277601
    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.

  • Patent number: 7295917
    Abstract: A method for determining a combustion chamber pressure of an internal combustion engine is described, which is used for a simple and accurate correction of the determined combustion chamber pressure. For this purpose, a first time curve of the combustion chamber pressure is compared with a second time curve of the combustion chamber pressure. A correction factor is determined as a function of the comparison result. The determined combustion chamber pressure is corrected via the correction factor.

  • Patent number: 7260469
    Abstract: In a method for operating an internal combustion engine, a first data quantity is derived based on a signal of a first sensor which detects the pressure in a first combustion chamber of a plurality of combustion chambers, and a second data quantity is derived based on a signal of a second sensor, which second data quantity is a function of the pressure variation in at least one of the plurality of combustion chambers. The first data quantity and the second data quantity are functions of the pressure variation in the same combustion chamber, and a drift of the second sensor is ascertained from a change over time in the second data quantity with respect to the first data quantity.
