To improve an electromechanical device, it is proposed that the actuator drive is arranged entirely in the housing of the actuator up to the electric line.

Abstract: A method for detecting the icing of a particulate filter, especially of a gasoline particulate filter, includes determining the temperature of the exhaust gas flow flowing through the particulate filter, whereby icing of the particulate filter is detected on the basis of the determined temperature of the exhaust gas flow. The method is improved in that the temperature of the exhaust gas flow upstream from the particulate filter and the temperature of the exhaust gas flow downstream from the particulate filter are determined, whereby on the basis of the measured temperature difference, the heat input into the particulate filter and the quantity of water present in the particulate filter are determined, whereby the aggregates states of the water present in the particulate filter are calculated by drawing up a balance of the heat quantity.

Abstract: A clutch actuation mechanism for actuating a clutch operator of a spring loaded friction clutch having at least a motor driven rotary disc for being connected to the clutch operator enables to operate the motor with an essentially constant and reduced torque, if a pin is attached to the disc with an offset from the disc's rotary axis, and if a lever has a curved contacting surface and if a spring forces the lever with its contacting surface against the pin to thereby provide an additional torque to the disc. Thus, the pin travels over the contacting surface when the disc rotates to open or close the spring loaded clutch via the clutch operator and the curvature enables to adapt the torque provided by the spring to the torque required to compensate for the clutch spring.
