Control system and method for heating an oxygen sensor |
| 摘要 |
A control system includes a temperature determination module and a heater control module. The temperature determination module determines a temperature of an oxygen sensor in an exhaust system of an engine. The heater control module applies a heat cycle to combust deposits on the oxygen sensor by activating a heating element of the oxygen sensor to increase the temperature of the oxygen sensor to greater than 800 degrees Celsius. |

1. A system, comprising:
an oxygen sensor configured to be disposed in an exhaust system of an engine and including a heating element; a first electronic circuit configured to determine a temperature of the oxygen sensor; a second electronic circuit configured to apply a heat cycle to combust deposits on the oxygen sensor by activating the heating element of the oxygen sensor to increase the temperature of the oxygen sensor to greater than 800 degrees Celsius; a third electronic circuit configured to initiate the heat cycle based on at least one of a vehicle mileage and a mass airflow in an intake system of the engine; and a power supply, wherein the second electronic circuit activates the heating element by controlling the power supply to supply power to the heating element. |
