Abstract

Die Erfindung betrifft eine Temperaturerfassungseinrichtung für eine Brennkraftmaschine. Die erfindungsgemäße Temperaturerfassungseinrichtung umfasst eine Trägerstruktur, ein an der Trägerstruktur aufgenommenes erstes Sensorelement, ein ebenfalls an der Trägerstruktur aufgenommenes zweites Sensorelement, eine Motor-Luftführungseinrichtung zur Zuleitung eines Motoransaugluftstromes zu dem ersten Sensorelement und eine Kühler-Luftführungseinrichtung zur Zuleitung eines durch einen Motorkühler hindurchgetretenen Kühler-Luftstromes zu dem zweiten Sensorelement. Hierdurch wird es möglich, durch einen kompakte und vormontierbare Baueinheit die Temperaturen der beiden Luftströme zentral zu erfassen, wobei die gewonnenen Messsignale unter vermindertem Verkabelungsaufwand in ein fahrzeugseitig vorgesehenes Kabelbaumsystem eingekoppelt werden können.

Figure 00000001
The invention relates to a temperature detection device for an internal combustion engine. The temperature detection device according to the invention comprises a support structure, a first sensor element received on the support structure, a second sensor element also received on the support structure, an engine air guide device for supplying an engine intake air flow to the first sensor element and a cooler air guide device for supplying a cooler that has passed through an engine cooler. Air flow to the second sensor element. This makes it possible to record the temperatures of the two air flows centrally by means of a compact and preassembled structural unit, the measurement signals obtained being able to be coupled into a wiring harness system provided on the vehicle with a reduced amount of wiring.
