  • Patent number: 9983090
    Abstract: The invention relates to a system (1) and to a corresponding method for tank leakage diagnosis. The system (1) comprises a fuel tank (3), a pressure source (5, 9), and a pressure sensor (7). The pressure source (5, 9) is configured to increase the pressure in the fuel tank (3). The pressure sensor (7) is configured to detect the pressure progression at the fuel tank (3). The system (1) is configured to seal the fuel tank (3) in a gas-tight manner such that the fuel tank (3) can be used as a pressure store. Furthermore, the system (1) is configured to conclude, independently of a current operation of the pressure source (5, 9) based on the determined pressure progression at the fuel tank (3), that a leak is present.

  • Patent number: 9309852
    Abstract: A method for activating an injector in a fuel injection system in an internal combustion engine, the fuel injection system including a plurality of injectors and a quantity of fuel injected with the aid of an injector being a function of the activation period of the injector. An injector-individual correction value for the activation period is ascertained for at least one injector as a function of a pressure and a temperature of the fuel to be injected and the activation for this injector takes place under consideration of the injector-individual correction value.

  • Patent number: 9228520
    Abstract: A method for operating a valve actuated by way of an actuator, in particular a fuel injection valve of an internal combustion engine of a motor vehicle, in which a first delay time is identified, which time characterizes a time difference between a point in time of a first change in an energization signal for the actuator and a point in time of a first change in the operating state of the valve corresponding to the first change in the energization signal. According to the present invention, from the first delay time at least one second delay time of the valve is inferred, which latter time characterizes a time difference between a point in time of a second change, different from the first change, in the energization signal and a point in time of a second change in the operating state of the valve corresponding to the second change in the energization signal.

  • Patent number: 8272361
    Abstract: The aim of the invention is to optimize the running smoothness of an internal combustion engine. To achieve this aim, the individual cylinders are synchronized with respect to their torque contribution. According to the method, fuel is injected into the combustion chamber of a cylinder in at least one injection step, the at least one injection contributing to the torque of the internal combustion engine. Fuel is injected into the combustion chamber of the cylinder in a torque neutral manner by way of a secondary injection during a working stroke of the cylinder and the amount of fuel of the secondary injection us calculated in such a manner that the exhaust gas substantially corresponds to a stoichiometric air/fuel mixture.

  • Publication number: 20120184182
    Abstract: A method for fine boring of internal surfaces of bore holes in work pieces as well as a machining plant for executing this method. The fine machining, fine boring, and honing include fine boring of a bore hole of a work piece using a fine boring tool; transferring the work piece into a honing device; measuring the fine bored bore hole with a measuring device associated with the honing device; and controlling the operation of the fine boring device depending on the bore hole measuring signal received by the measuring device. An output fine boring machining, arranged directly upstream of the transfer, is dimensioned as semi-finishing machining, and is carried out with a fine boring tool having at least one adjustable cutting edge. The position of the adjustable cutting edge is controlled depending on the bore hole measuring signal.
