摘要： A method is provided for determining a time duration for an electric actuation of a valve which has a coil drive, in particular of a direct-injection valve for an internal combustion engine. The method may include a deactivation of a current flow through a coil of the coil drive, such that the coil is in a currentless state, a detection of a time profile of a voltage induced in the currentless coil, a determination of the closing time of the valve on the basis of the detected time profile, and a determination of a time duration of the electric actuation of the valve for a future injection process on the basis of the determined closing time. A corresponding device and a computer program for carrying out the described method are also disclosed.

摘要： A valve for the injection of fuel has a valve body (4) which has a recess (5) in which a valve needle (6) that is movable in the axial direction is arranged. The valve needle (6) together with the valve body (4) forms an injection nozzle (7) in a downstream zone. In a closed position the valve needle (6) prevents a stream of fuel from passing through the injection nozzle (7) but otherwise leaves it unimpeded. At a downstream end the injection nozzle (7) has a deflecting element (20) so arranged that a stream of fuel is deflected from taking a predominantly upstream course from the deflecting element (20).

摘要： A method and system for controlling an internal combustion engine is provide. The engine has a fuel-supply device, a low-pressure circuit and a high-pressure pump, to which a control valve for a volumetric flow is allocated is provided. Said pump is coupled on the inlet side to the low-pressure circuit and transports fuel to a fuel accumulator. An estimated value of the drive torque of the high-pressure pump is determined in accordance with the fuel pressure in the fuel accumulator. A loss torque is determined in accordance with the estimated value for the drive torque of the high-pressure pump and additional loss-torque fractions, which are dependent on a motor speed and additional operating variables. A target torque is determined in accordance with the loss torque and an actuating signal for controlling an actuator of the internal combustion engine is generated from the target torque.

摘要： A defect of prior art methods for controlling an internal combustion engine based on families of characteristics depending on pressure and rpm is that an air mass being taken in is a function of an air temperature in a cylinder and thus of heating in an intake section. This defect is corrected according to the invention by multiplying a basic fuel value taken from a basic family of characteristics by a factor having a denominator containing a correction temperature being determinative for heating-up the intake air in the intake section as a function of its temperature and of an air flow and being taken from a corresponding family of temperature characteristics.
