Abstract: The present invention relates to a device and a method for dividing up a total fuel amount, which is to be injected into the combustion chamber of a cylinder during a combustion cycle, into a plurality of injections. To this end, a first fuel amount, which is to be injected during a first injection is determined, a fourth, minimum fuel amount for a third injection is determined, and the total fuel amount minus the first fuel amount is compared to the fourth, minimum fuel amount. When the total fuel amount minus the first fuel amount is greater than or equal to the fourth, minimum fuel amount, the first fuel amount and a second fuel amount, which is to be injected into the combustion chamber of the cylinder during a second injection, are set to zero, and a third fuel amount, which is to be injected during a third injection, is set to the total fuel amount.

Abstract: A system and method for fuel metering in a motor vehicle in which the fuel in a reservoir has a definable pressure. A second device for reducing the pressure and a first device for issuing a signal relevant to vehicle safety are provided. The pressure is reduced by the second device in response to the signal relevant to vehicle safety. The first device is configured in such a way that, in order to increase vehicle stability, the braking effect for at least one vehicle wheel brake can be modified, and the signal relevant to vehicle safety is issued as a function of a definable modification of the braking effect.

Abstract: A method of safeguarding against manipulation of an odometer or trip recorder in a motor vehicle, in which the instantaneous odometer reading is determined when the engine of the motor vehicle is stopped and that odometer reading is stored in an on-board control unit, in particular an engine control unit. Moreover, the instantaneous odometer reading of the odometer on restarting the engine is determined, and the odometer reading found on restarting the engine is compared with the stored odometer reading. Suitable measures are initiated for the case when the odometer reading found on restarting the engine and the stored odometer reading do not match.

Abstract: A method for operating a self-igniting, air-compressing internal combustion engine, in which the engine is supplied with fuel by an injection system that has a high-pressure fuel reservoir, which is supplied with fuel by a high-pressure fuel pump and outputs fuel to electrically controlled injection valves. A control unit is provided, which detects the operating mode of the engine and upon occurrence of an overrunning mode allows a pressure increase in the high-pressure fuel reservoir. On resumption of normal operation, the drive of the high-pressure fuel pump is then interrupted, and the engine is supplied from the fuel previously stored at elevated pressure, until a lower limit value of the high pressure fuel is attained.

Abstract: A fuel injection system for internal combustion engines in which a high pressure fuel reservoir is provided, from which fuel is supplied to injection valves in an electrically controlled manner. In order to reduce damage which occurs when there are leaks from the high pressure reservoir, the high pressure reservoir is enclosed by a sheath that can capture the emerging leakage fuel.

Abstract: A method and a device for monitoring a fuel-metering system, in particular a common-rail system for a diesel fuel engine. A defect is recognized on the basis of an output signal from a structure-borne noise sensor.

Abstract: A guide arrangement for elevators, particularly for vertical elevators. The guide arrangement is arranged in a shaft having a shaft wall. The guide arrangement includes a self-contained inherently stiff rail frame with at least two parallel guide rails which are rigidly connected to each other, the guide arrangement further includes fastening members for connecting the rail frame to the shaft wall, wherein the fastening members are springs.

Abstract: The invention deals with a cable tensioning system for elevators with separate drive cable and support cable lines 10, 11, which both engage at an elevator cabin 12 and also at a counterweight 13, characterized in that the cable tensioning system comprises a rocker 20 configured as a lever and supported at the counterweight 13 or the elevator cad 12, at which rocker the support cable 11 and the drive cable 10 are fastened to be spaced from each other, that the spacing ratio a: b of the attachment points 31, 32 of the cable lines 10, 12 at the rocker 20 from the support point 21 of the rocker 20 at the counterweight 13 or the elevator cab 12 define the cable tension or pull ratio required for the driving capacity.

Abstract: A system for controlling a motor vehicle includes a first device for determining control data required for controlling the motor vehicle. A second device monitors the first device. The first device determines second data on the basis of first data, pursuant to a test function. The second device determines third data on the basis of the first data, pursuant to the same test function. The first and/or the second device recognizes an error state relevant to safety, dependent upon a comparison between the second data and the third data.

Abstract: In a method and device for controlling an internal combustion engine, particularly a diesel engine, when the internal combustion engine is started up, a power-regulating, controlling mechanism is triggered in a first step so as to allow it to assume a starting position. A starter is triggered in a subsequent step. An interrupting device, which is operatively connected to the power-regulating, controlling mechanism, is released only after a safety condition is fulfilled.
