An oxygen sensor arrangement

摘要

The present invention relates to a heating arrangement (10) being arranged in a vehicle. The vehicle comprising a catalyst (13) and at least one oxygen sensor (14) arranged inside the catalyst (13). The heating arrangement (10) comprising a heating element (17) being arranged to provide a heating effect on at least a part of the areas inside the catalyst (13). The heating effect of the heating element (17) is applied adjacent a sensor tip (16) of the oxygen sensor (14) for heating a part of the substantially upstream areas (18) of the catalyst (13) surrounding the sensor tip (16).
