Abstract: The invention relates to a method for producing MoO2Cl2 under inert conditions, comprising the steps of: (i) charging a reaction vessel with MoO2, (ii) reacting the MoO2 with supplied Cl2 in the reaction vessel at a first temperature T1 to give gaseous MoO2Cl2, (iii) transferring the gaseous MoO2Cl2 into a receiving vessel, (iv) resublimating the gaseous MoO2Cl2 in the receiving vessel to give solid MoO2Cl2 at a second temperature T2 that is lower than T1, and (v) recovering solid MoO2Cl2 with a purity determined by ICP-OES/MS of 99.9996 wt. % or more. The invention also relates to high-purity MoO2Cl2, the use thereof, and electronic components.

Abstract: A plate armature damping device for a tilting armature valve includes at least one damping body which can be fixed to a plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element. The at least one damping body has a geometric contour including at least one bulge on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases.

Abstract: An internal combustion engine having one injection valve (3) per cylinder and at least one additional port injector (5) for injecting fuel into combustion air which is fed to the cylinders (2) in the intake tract (4). The port injector (5) havs two supply inlets (10, 11) which can be closed off. A control unit (8) determines the quantity of fuel which is to be delivered as a function of the operating state of the internal combustion engine (1). Separately provided starting fuel is delivered by the port injector (5) during the warm-up phase of the internal combustion engine.

Abstract: An apparatus for setting the throttle position in an air feed or intake assembly of an internal combustion engine in accord with desired torque including a two setting, switchable suction pipe. Torque fluctuations are inhibited during the switchover between the two settings so that uncomfortable drivability related effects are eliminated.

Abstract: An electronic control device for the optional control of various types and operating modes of internal combustion engines includes a calculation device configured to calculate the respectively required manipulated quantities, including at least the manipulated variable (Ti) for the predetermination of the fuel quantity to be injected and the manipulated variable (&agr;) for the predetermination of the throttle valve position of the throttle valve in the intake pipe, dependent on respectively required input parameters, including at least the desired quantity of heat (WM). A switchover device is configured to allocate, dependent on the operating mode, the respectively required input parameters and/or quantities derived therefrom as input quantities for the respectively required calculation device.

Abstract: A method and control apparatus for the correction of a mathematically determined torque in the drive train of a motor vehicle, in which a recognition signal for distinguishing between automatic and manual transmissions is produced and motor and transmission operating states (selected in accord with the recognition signal) in which the actual torque applied to the crankshaft is equal to zero are established. When the motor and transmission operating states are reached, the mathematically determined torque associated with the operating states is compared to the actual (zero) torque, and the difference between the mathematically determined torque and the actual torque is used as a control factor for the correction of additional computed torques.
