Method for operating a particulate filter disposed in an exhaust-gas region of an internal combustion engine and device for implementing the method

Microstructured sensor for the detection of IR radiation

Method for Determining Oil Dilution in a Internal Combustion Engine Featuring Post-Injection

Oil status sensor e.g. for motor vehicle, has sensor fitted to oil module and provides lubrication to internal-combustion engine and for steering gear

FLUID SENSOR DEVICE

Tank level indicator has float lever which is supported in pivot bearing around rotating axis in pivoting manner, where acceleration sensor has metering shaft

Spectroscopic gas sensor for detecting concentration of e.g. ethanol in liquid mixtures, has infrared radiation source for discharging infrared radiation, and evaluating device receiving measurement signal to correct another signal

Spectroscopic sensor, particularly gas sensor, has infrared radiation source for emitting infrared radiation, absorption passage for receiving gas or liquid, and optical filter for wavelength-selective transmission of infrared radiation

Capacitive level measuring device for e.g. fuel tank of motor vehicle combustion engine, has profile bars standing at certain angle from each other, and two surface electrodes are formed at each surface of profile bars

Method e.g. for estimating fuel introduction into motor oil, involves tracking whether diesel particulate filter is regenerated after a motor is turned
