| 20080264155 | Method and Device for Monitoring a Fuel Supplying Device of an Internal Combustion Engine - The invention relates to a fuel supplying device comprising a low-pressure circuit, a high-pressure pump which is coupled to the low-pressure circuit on the input side thereof and transports fuel into a fuel accumulator, and an actuator which controls the fuel flow rate of the high-pressure pump. In the event of a stationary load, a first value of a fuel pressure and a first actuating signal of the actuator are determined, a second value of the fuel pressure is set, and said second value being larger or smaller than the first value of the fuel pressure by a pre-determined amount, a second actuating signal of the actuator is determined once the second value of the fuel pressure has been set, and an error in the fuel supplying device is detected according to the first and second actuating signals of the actuator. | 10-30-2008 |
| 20080269984 | Method for Controlling a Fuel Supplying Device of an Internal Combustion Engine - Disclosed is a fuel supplying device of an internal combustion engine, comprising a low-pressure circuit, a high-pressure pump coupled to the low-pressure circuit and conveys fuel into a fuel reservoir, a volume flow control valve assigned to the high-pressure pump, an electromechanical pressure regulator connected to the fuel reservoir and the low-pressure circuit and can direct fuel from the fuel reservoir into the low-pressure circuit, a regulating mechanism which generates an actuation signal for the volume flow control valve by a first controller in a first mode which generating an actuation signal for the electromechanical pressure regulator with the aid of a second controller in a second mode. The mode of the fuel supplying mechanism is switched in accordance with a fuel pressure error value resulting from a detected fuel pressure and a predefined fuel pressure. The mode can additionally be switched according to the throughput of the high-pressure pump. | 10-30-2008 |
| 20090070012 | Method and Device for Operating an Internal Combustion Engine - In a first operating state, the fuel metering of one of the cylinders is controlled in first metering pulses with the same pulse characteristic during a respective one working cycle, and the metering of fuel into the other cylinders by at least one second metering pulse with a different pulse characteristic. The first pulse number and characteristic is predefined such that the same fuel mass should be metered based on an assumed injection valve characteristic as with the one second metering pulse. Depending on the measurement signal, a correction value for the one cylinder is determined. To meter the fuel based on the assumed injection valve characteristic, a single first metering pulse would be generated during a respective one working cycle. The correction value for the one cylinder is used during the rest of the operation to adapt the first metering pulse in the second operating state. | 03-12-2009 |
| 20090150046 | Method for controlling an internal combustion engine and internal combustion engine - A control method for an internal combustion engine with at least one pressure accumulator in which fuel is stored under pressure, in order to supply pressurized fuel to at least one injection valve, and at least two high-pressure pumps which are connected to the at least one pressure accumulator in such a way that they can supply fuel to this at least one pressure accumulator either jointly or separately, with, if at least one condition is fulfilled, the high-pressure pumps being operated in a special operating mode in which only one of the high-pressure pumps supplies fuel to the at least one pressure accumulator, and with the high-pressure pumps being otherwise operated in a normal operating mode in which the at least two high-pressure pumps jointly supply fuel to the at least one pressure accumulator. | 06-11-2009 |
