摘要： The invention concerns a procedure for the voltage controlled output adjustment of a sensor heater in the exhaust gas system of an internal combustion engine. In order that such a procedure, whereby the operating temperature of the sensor is achieved in the shortest amount of time, can be implemented without the sensor being damaged in the process, provision is made according to the invention, that the heating voltage in a beginning phase of the heat-up phase of the heater is brought to a high value either very quickly in respect to a subsequent phase or precipitously brought to that high value, preferably the operating voltage; and subsequently the heating voltage is continuously or virtually continuously reduced.

摘要： The invention is directed to an arrangement for detecting the oxygen content in the exhaust gas of an internal combustion engine. The arrangement includes a concentration measuring cell operating pursuant to the Nernst principle. The concentration measuring cell has a measuring electrode, a solid electrolyte and a reference electrode and a series circuit which includes a direct voltage source and a series resistor. The series circuit connects the measuring electrode to the reference electrode. The measuring electrode communicates with the exhaust gas of the internal combustion engine and is connected to the reference electrode via the solid electrolyte. The reference electrode communicates with the reference gas volume. The reference gas volume is partitioned from the exhaust gas and from the ambient air so that a particle exchange between the reference gas volume and the exhaust gas as well as between the reference gas volume and the ambient air is at least made more difficult. The output voltage of the concentration measuring cell defines a measure for the difference of the oxygen concentrations in the exhaust gas of the engine and the reference gas volume. The output voltage of the direct voltage source and/or the value of the series resistance is so pregiven that an electric current Ip is always so directed that oxygen is transported from the exhaust gas to the reference gas volume independently of the output voltage of the concentration measuring cell. The current Ip flows in a current circuit including direct voltage source, series resistance and concentration measuring cell.

摘要： The invention relates to a measuring sensor having an internal pump oxygen reference atmosphere which, in turn, has a device for compensating pressure which is so dimensioned that, on the one hand, mechanical damage because of overpressure in the reference volume is reliably prevented and, on the other hand, external influences on the composition of the pumped measured gas atmosphere are substantially excluded. The device for compensating for pressure is so dimensioned according to the invention that the particle exchange between ambient air and gas to be measured is opposed by a resistance which is defined by the limit current principle.

摘要： The invention is directed to a method of operating an exhaust-gas probe having a pumped reference atmosphere in a relatively closed volume. In this method, the oxygen ion current, which carries the pump current Ip to the reference atmosphere, is temporarily increased under specific conditions. In this way, an adulteration of the reference atmosphere can be more rapidly eliminated. This adulteration can occur because of fuel particles which diffuse in.
