摘要:
A method for determining an opening behavior of a combustion engine fuel injector having a coil drive includes: applying to a coil of the coil drive an electrical test excitation that is weaker than an electrical standard excitation applied to the coil during normal operation of the engine, such that an opening position of the fuel injector is achieved at a point at which the coil drive is not in magnetic saturation; measuring the chronological progression of an electrical variable of the coil; determining a first point in time at which the fuel injector reaches its opening position under the influence of the electrical test excitation, based on the measured chronological progression of the electrical variable, and determining a second point in time at which the fuel injector would reach its opening position under the influence of the electrical standard excitation, based on the determined first point in time.

A method is disclosed for operating an actuator having a coil and a displaceably mounted armature driven by a magnetic field generated by the coil, in a measurement operating mode for ascertaining a time at which the armature reaches its stop position after activation of the actuator. The method includes applying to the coil an actuation voltage signal dimensioned such that the expected armature stop time falls in a time window in which a temporally constant voltage is applied to the coil, detecting an intensity profile of the current flowing through the coil within the time window, and determining the armature stop time, based on an evaluation of the detected current intensity profile. A method for operating such an actuator is also disclosed, wherein information about the stop time is obtained in a measurement operating mode and used in a series operating mode for optimized actuation of the actuator.

A system is arranged to remove carbon dioxide (CO2) from a gas stream by bringing the gas stream into contact with a circulating ammoniated solution stream such that CO2 is removed from the gas stream by the ammoniated solution stream. A method of removing non-volatile compounds from the circulating ammoniated solution stream includes: introducing a portion of the circulating ammoniated solution stream into a gas-liquid separating device; and separating the introduced ammoniated solution into an ammonia rich gas phase and a liquid phase comprising the non-volatile compounds; and reintroducing the ammonia rich gas phase into the circulating ammoniated solution stream.

Method for applying a coating layer to a tubular intraluminal implant, in particular to a vascular support (stent), where the surface of the implant is perforated by a plurality of apertures, and where the coating layer is produced by deposition of material onto the surface of the implant. The implant is first pushed onto a cylindrical holder 4, a sacrificial material, in particular copper, is then deposited onto the surface of the implant until the deposited sacrificial material almost entirely fills the apertures, the coating layer is then deposited onto the surface of the implant provided with sacrificial material, and then the cylindrical holder 4 and the sacrificial material situated in the apertures 3 are removed.
