Example Embodiment

[0026] FIG. 1 shows an exhaust gas turbocharger 12 having a turbine 13 and a compressor 14. The compressor wheel 15 is rotatably arranged in the compressor 14 and connected with the turbine shaft 16. The turbine shaft 16 is also rotatably arranged and its other end is connected to the turbine 17. The hot exhaust gas enters the turbine 13 from an internal combustion engine not shown here through the turbine inlet 18, thereby rotating the turbine 17. The exhaust gas flow leaves the turbine 13 through the turbine outlet 19. The turbine 17 is connected to the compression wheel 15 via a turbine shaft. Therefore, the turbine 13 drives the compressor 14. Air is sucked into the compressor 14 through the intake port 21, and then compressed in the compressor 14 and delivered to the internal combustion engine through the exhaust port 20.

[0027] figure 2 The compressor 14 of the exhaust gas turbocharger 12 with a turbine shaft 16 and a compressor wheel 15 is shown. The compressor wheel 15...

Abstract

The invention relates to an active sensor element for recording the speed of an exhaust gas turbocharger, comprising a suppressor circuit which has at least one diode. In order to specify a device for temperature measurement at the turbocharger and in particular at the turbocharger in the region of the active sensor, the current-voltage characteristics of the diode are evaluated for determining the temperature in the sensor element.

Description

technical field [0001] The invention relates to an active sensor element according to the preamble of claim 1 and to a method for determining the temperature of an active sensor element. Background technique [0002] The power produced by the internal combustion engine depends on the amount of air and the corresponding amount of fuel that can be supplied to the internal combustion engine for combustion. In order to increase the power of an internal combustion engine, a greater amount of combustion air and fuel must be supplied to the internal combustion engine. This increase in power is achieved in naturally aspirated engines by increasing the working volume of the cylinder or by increasing the rotational speed. But substantially increasing the cylinder displacement results in a heavier, larger and therefore more expensive internal combustion engine. [0003] A technical solution that is often used to improve the efficiency of internal combustion engines is supercharging. ...
