Patent number: 9803578Abstract: An injection valve has a moveable nozzle needle that controls a dosing of fluid and a solid-state actuator that actuates the nozzle needle. To operate the injection valve, values of a characteristic for a load state of the actuator are detected at a predetermined sampling rate. A start reference time and end reference time are determined correlating in chronological terms to an operating phase in which the solid-state actuator is discharged to a predetermined reference state by absorbing the energy in a discharging resistor. A correction reference value is determined based on a detected value of the characteristic correlating to an end of the operating phase, and a predetermined reference value. A correction value pattern is determined based on the end reference time, the start reference time, and the correction reference value. The detected values of the characteristic for the load state are determined based on the correction value pattern.Type: GrantFiled: August 14, 2013Date of Patent: October 31, 2017Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Peter Matthias Russe, Anselm Schwarte

Patent number: 9611823Abstract: A method for controlling the injection quantity of a piezoinjector of a fuel injection system, which comprises a nozzle needle displaceable by a piezoactuator. Based on the instantaneous injection quantity, a selection is made among various control methods. In a ballistic injector mode, a first control method is carried out, wherein both a needle closing point in time is equalized and a needle travel time is also equalized. In a full stroke injector mode, a second control method is carried out, wherein a needle closing point in time is equalized, but the needle travel time is not equalized.Type: GrantFiled: August 24, 2011Date of Patent: April 4, 2017Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Anselm Schwarte, Steffen Lehner, Manfred Kramel

Patent number: 9127632Abstract: A method for detecting error-containing components of a piezo-injector in an internal combustion engine fuel-injection system is disclosed. The piezo-injector has a piezoelectric actuator and an injection needle driven thereby, and is configured for operation in a partial-stroke mode and a full-stroke mode. First, the internal combustion engine is brought to a defined operational point. Then, the time for the injector needle to strike its stop when said injector needle is opened, as well as the time for the injector needle to strike its needle seat again when said injector needle is closed, are measured. The measured times are compared to normal values determined at the test stand. Parameter(s) for the fuel-injection system are calculated, using different calculation models, and the results are stored. Finally, the calculated parameters of the different calculation models are compared to norm values determined at the test stand, and compared to one another.Type: GrantFiled: February 29, 2012Date of Patent: September 8, 2015Assignee: CONTINENTAL AUTOMATIVE GMBHInventors: Robert Hoffmann, Steffen Lehner, Anselm Schwarte, Simon Ruscheinski

Patent number: 9086028Abstract: An injection nozzle has a nozzle needle that suppresses metering of fluid in a closed position and otherwise allows the metering of fluid. Furthermore, the injection valve has a solid-state actuator that acts on the nozzle needle. A first operating phase is performed for a closing operation in a first operating mode, during which first operating phase the solid-state actuator is discharged to a predefined part charge. Furthermore, a second operating phase is performed, during which the solid-state actuator is operated as a sensor. An operating duration of the second operating phase is predefined such that the closed position of the nozzle needle is reached during the operating duration. A third operating phase is performed, during which the solid-state actuator is discharged further to a predefined reference state. In a second operating mode, the first and second operating phases are carried out and the third operating phase is omitted.Type: GrantFiled: June 7, 2011Date of Patent: July 21, 2015Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Anselm Schwarte, Peter Matthias Ruβe, Nicolas Nozeran
