Title: Temperature control circuit of air-fuel ratio sensor
Inventor: MINAMI NAOKI
IPC: G01N27/41
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To measure an air-fuel ratio accurately by measuring the internal resistance of a sensing cell at each reference time by time-sharing and turning on or off a heater so that the resistance of the sensing cell becomes constant. SOLUTION: A pumping cell is constituted of an electrode and zirconia so that a voltage can be generated owing to the difference in concentration between oxygen being accumulated in a reference gas region and oxygen in a diffusion room. A sensing cell moves oxygen between the diffusion room and an exhaust gas and is constituted of zirconia and an electrode. Then, a diffusion film is provided to constitute an air/fuel ratio sensor and allows oxygen to flow selectively. A resistor R1 biases the pumping cell, thus feeding oxygen into the reference gas region. A microcomputer 1 measures the internal resistance of the sensing cell at each reference time by time sharing and turns on or off a heater so that the resistance of the sensing cell becomes constant, thus measuring the internal resistance of an air/fuel ratio sensor in a double-cell configuration and improving accuracy.
