A crankcase ventilation device features a closing valve with a valve body, the valve body executes a positioning movement between a closed and an opened position. A sensor device for detecting the positioning movement of the valve body is disposed in the housing.

Crankcase ventilation device

Disclosed is a device and a method for neutralizing an acidic condensate in an internal combustion engine with exhaust gas recirculation system, wherein the exhaust gas recirculation system has an exhaust gas recirculation cooler for cooling a hot exhaust gas stream, a metering system is provided that meters an alkaline substance into the exhaust gas stream and is arranged upstream of the exhaust gas recirculation cooler.

Device and method for neutralizing acidic condensate in a motor vehicle

An actuator element suitable, for example, for actuating a rotatable disk or a flap valve shaft. The actuator includes a housing, a drive situated in the housing, and at least one position detector, in which a movably mounted piston rod in the housing is operatively connected to the drive for exerting a force effect, and in which the position detector includes at least one stationary Hall sensor and at least one magnet movable relative to the Hall sensor such that the magnet produces a magnetic field for generating a magnetic flux.
