An exhaust gas sensor for detecting a measurement gas component, having a ceramic sensor element fixed in a housing, and a double-walled protective pipe having outer and inner protective sleeves, the inner sleeve enclosing a gas chamber into which the sensor element extends with a segment at the measurement gas side, in the direction of a longitudinal axis of the sensor, and an annular chamber being formed between the outer and inner protective sleeves. The outer sleeve has a cladding surface having at least one opening configured as a swirling element, through which measurement gas can move into the annular chamber with rotation about a longitudinal axis of the sensor, and the inner sleeve has at least one opening that is adjusted and/or functionally optimized, as to a sensitive region of the sensor element, through which opening the measurement gas can move from the annular chamber into the gas chamber.

Exhaust gas sensor

Gas sensors are provided that are fashioned such that there is an increased flow over the sensor element. In this way, a good measurement dynamic is achieved even when these gas sensors are exposed to exhaust gases having a low flow speed.

Gas sensor

A sensor device for measuring at least one property of a fluid medium, in particular of an exhaust gas of an internal combustion engine. The sensor device includes at least one protective housing for accommodating at least one sensor element; within the protective housing, at least one flow path being provided that allows flow therethrough by the fluid medium. The flow path has a number of at least three deflection points, where the fluid medium undergoes a directional change about an angle of at least 90&#xb0;. The sensor device is highly resistant to thermal shock, while, at the same time, the sensor element has a high dynamic response.

A device for starting an internal combustion engine of a motor vehicle is described, which has a starter motor, an engaging relay, a starting current relay, a main current relay, a control unit and a switching module situated between the relays named and the control unit. The control unit is an engine control unit of the motor vehicle. The switching module has inputs which are connected to one output, respectively, of the engine control unit, and has outputs at which control signals for the relays named are provided. The outputs of the engine control unit are small signal outputs.

A switching device has an electromagnetic switching element and a controller, the switching element including two coils on one core which act on a shared armature. In order to implement an operation of the armature to be activatable as rapidly and simply as possible with low power consumption, the controller is designed to have a switch in the current path of the coil in each case to activate each coil.
