Abstract

PURPOSE:To accurately control the smoke value irrespective of the rotational speed of an engine by using as an air-fuel ratio sensor an oxygen sensor whose output characteristic varies by varying the power supply quantity to control the power supply quantity according to the driving condition. CONSTITUTION:In the air-fuel ratio controller which feedback controls the fuel injection quantity on the basis of the output of the air-fuel ratio sensor 11, the air-fuel ratio sensor 11 is constructed so that the internal space constituted by an inside louver 16 contains a plate-shaped heater attached sensor element 19 supported by an alumina insulating cylinder 18. Furthermore, the senser element 19 forms a sensor part 19a on the surface of a heat-resisting insulating base plate 26 such as alumina or the like, and a temperature controlling heater 27 mainly composed of platinum is embeddedly provided in the inner part of the base plate 26. The power supply quantity through lead wires 20a and 20b to the sensor part 19a is controlled according to the detected value of the engine rotational speed whereby the air-fuel ratio can be controlled according to the smoke value.
