Definitions
- the cylinder pressure sensor DS thus provides an internal pressure of the cylinder CY associated, in particular in substantially proportional, electrical signal as Sensorrohsignal ZS, which is converted by the evaluation / logic unit LE, in particular a transmitter such as a transducer into a voltage signal SV and thereby possibly amplified.
- This voltage signal SV is scaled by dividing it into the different measuring range sections such as A, B, C, ie its original dynamic range is limited to a fixed voltage level range.
- This sensor output signal SS is transmitted to the engine control unit ECU via a measuring line SL. There it is with
- the engine control unit ECU uses one or more different operating parameters of the internal combustion engine CE.
- the speed N of the crankshaft of the internal combustion engine CE and the adjusting angle TPS of the throttle valve determine the current operating point BP for the cyclical combustion process.
- a sensor value for example, a voltage, an electric current, etc. are used.
- the low-pressure region is the first 360 ° crankshaft angle range and the high pressure region associated with the second 360 ° crankshaft angle range.
- the corresponding measuring range is then selected.
