Abstract: The identification of a leak in the intake port (1) of an internal combustion engine (3) with lambda regulation (8) can be performed by the generation of an evaluation signal in accordance with a control signal of the lambda regulation (8) and the monitoring of the evaluation signal with respect to the transgression of a limiting value. If a leak occurs in the intake port (1), the internal combustion engine (3) receives an additional air mass, which is not registered by an air mass sensor (2). The additional air mass is compensated by the lambda regulation (8) by means of an increase in the value of the control signal, in such a way that the likewise increased value of the evaluation signal can be used for identifying leaks in the intake port (1). In this way, it is possible to determine, in particular, if a crank housing ventilation (5) of the internal combustion engine (3) is still connected correctly to the intake port (1).

Abstract: For a detachable electrical onnection of high-current contacts with cable strands, a clamping device is formed from a clamping tube and a contact part. The clamping tube is provided with a funnel-shaped connection opening and a connection chamber, into which the cable strands are insertable, wherein a clamping shoulder with a conical surface provided in the connection chamber adjoins the connection opening. The contact part, which can be screwed in the centre of the clamping tube and is thus displaceable axially, likewise has a conical surface, which penetrates the centre etween the bared strands on assembly and presses these against the conical surfaces and the clamping shoulder. The angles of the conical surfaces in the connection chamber and the contact part are executed differently in this case.
