Definitions
- the present invention relates to a control device for an internal combustion engine.
- An oxygen concentration sensor including a diffusion rate layer covering an electrode is disposed in an engine exhaust passage, and an air-fuel ratio is controlled based on an output of the oxygen concentration sensor (see Patent Document 1). .
- This oxygen concentration sensor generates an output voltage higher than the reference voltage corresponding to the theoretical air-fuel ratio when the air-fuel ratio is smaller than the stoichiometric air-fuel ratio, and is lower than the reference voltage when the air-fuel ratio is larger than the stoichiometric air-fuel ratio. Generate output voltage. Therefore, when the output voltage is higher than the reference voltage, it is determined that the air-fuel ratio is smaller than the theoretical air-fuel ratio, and control is performed so that the air-fuel ratio becomes larger. On the other hand, when the output voltage is lower than the reference voltage, it is determined that the air-fuel ratio is larger than the theoretical air-fuel ratio, and control is performed so that the air-fuel ratio becomes smaller.
- the diffusion rate layer has a function of regulating the diffusion rate of the exhaust gas. In this oxygen concentration sensor, no voltage is applied between the exhaust gas side electrode and the reference gas side electrode.
- Patent Document 1 since the exhaust gas side electrode is covered with the diffusion-controlling layer, the responsiveness of the oxygen concentration sensor is lowered. As a result, the output voltage of the oxygen concentration sensor has hysteresis. That is, the change in output voltage when the air-fuel ratio increases across the stoichiometric air-fuel ratio is different from the change in output voltage when the air-fuel ratio decreases across the stoichiometric air-fuel ratio. Therefore, particularly when the air-fuel ratio is close to the stoichiometric air-fuel ratio, the output voltage may be lower than the reference voltage even though the air-fuel ratio is smaller than the stoichiometric air-fuel ratio. Nevertheless, the output voltage may be higher than the reference voltage. As a result, the air-fuel ratio cannot be accurately detected, and therefore the air-fuel ratio may not be accurately controlled. To solve this problem, a complicated configuration or control is required.
- a sensor for detecting the oxygen concentration or air-fuel ratio in the exhaust gas comprising an electrode and an electric circuit for applying a reference voltage between these electrodes, is disposed in the engine exhaust passage, and the oxygen concentration or air-fuel ratio is determined.
- the sensor for detecting has a characteristic that the output current continues to increase without having a limit current region when the voltage applied between the electrodes is increased when the air-fuel ratio is constant, and the oxygen concentration or the air-fuel ratio.
- the air / fuel ratio can be accurately controlled with a simple configuration.

- a reference gas chamber 57 into which a reference gas is introduced is formed in the internal space of the solid electrolyte body 54. Therefore, the reference gas side electrode 56 is in contact with the reference gas.
- the reference gas is formed from the atmosphere, and therefore the reference gas side electrode 56 is also referred to as an atmosphere side electrode.

- the exhaust gas side electrode 55 is covered with a coating layer 58, the coating layer 58 is covered with a catalyst layer 59, and the catalyst layer 59 is covered with a trap layer 60.

- an electric circuit 70 includes an offset power supply 71 that supplies an offset voltage Vo, a reference power supply 72 that supplies a reference voltage Vr, an operational amplifier 73 to which a power supply voltage Vb is applied, an electrical resistor 74 that provides an electrical resistance R, and An output terminal 75 is provided.
- the offset power supply 71 is connected to the atmosphere-side electrode 56 that is a positive electrode on the one hand, and is connected to the reference power supply 72 on the other hand, and the reference power supply 72 is connected to the + terminal of the operational amplifier 73.
- the exhaust gas side electrode 55 which is a negative electrode, is connected to the ⁇ terminal of the operational amplifier 73 on the one hand and to the output terminal 75 via the electric resistor 74 on the other hand.
- the output terminal 75 is input to the electronic control unit 30 (FIG. 1), and the electronic control unit 30 detects an output voltage Eo that is a potential at the output terminal 75.
- the electric circuit 70 applies a voltage between the electrodes 55 and 56 so that the voltage Vs between the electrodes 55 and 56 is maintained at the reference voltage Vr. At this time, a current Ip flows between the electrodes 55 and 56.
- Expression (1) can be rewritten as the following expression (2).
- Ip (Eo ⁇ Vr ⁇ Vo) / R (2)
- the output voltage Eo is detected, and the output current Ip is obtained using the equation (2). In another embodiment, the output current Ip is detected directly.
- the downstream sensor 27d also includes a circuit that detects the impedance of the sensor element 51.
- the impedance of the sensor element 51 represents the temperature of the sensor element 51 or the downstream sensor 27d.
- the exhaust gas contacts the exhaust gas side electrode 55. Therefore, at the exhaust gas side electrode 55, HC and CO in the exhaust gas react with oxygen. As a result, a current Ip flows between the electrodes 55 and 56.
- FIG. 4 shows the relationship between the interelectrode voltage Vs of the downstream sensor 27d and the output current Ip when the air-fuel ratio is maintained at the stoichiometric air-fuel ratio.
- the output current Ip continues to increase as the interelectrode voltage Vs increases.
- FIG. 5 shows the relationship between the output current Ip 'of the linear characteristic air-fuel ratio sensor and the interelectrode voltage Vs' when the air-fuel ratio is maintained at the stoichiometric air-fuel ratio.
- the output current Ip ′ increases as the interelectrode voltage Vs ′ increases.
- the output current Ip' becomes substantially constant.
- the output current Ip ′ increases as the interelectrode voltage Vs ′ increases.
- the voltage region where the output current Ip ′ is substantially constant is referred to as a limiting current region LC.
- the reason why the output current Ip ′ has the limit current region LC is that the diffusion of the exhaust gas to the exhaust gas side electrode is limited by the diffusion rate controlling layer.
- the output current Ip ′ has a limit current region LC, the response of the air-fuel ratio sensor is lowered, and the output current Ip ′ may have hysteresis.
- the output current Ip of the downstream sensor 27d of the embodiment according to the present invention does not have a limit current region as shown in FIG. This is because the downstream sensor 27d of the embodiment according to the present invention does not include a diffusion rate limiting layer. As a result, the response of the downstream sensor 27d is improved.
- the reference voltage Vr is applied between the electrodes 55 and 56 as described above, the reaction at the exhaust gas side electrode 55 is promoted. As a result, the output current Ip has no hysteresis. Therefore, the air-fuel ratio can be accurately detected.
- the coating layer 58 of the downstream sensor 27d of the embodiment according to the present invention is different in configuration from the diffusion rate limiting layer of the linear characteristic air-fuel ratio sensor in that the output current Ip is formed so as not to have a limit current region.
- the coating layer 58 has a larger porosity than, for example, a diffusion-controlled layer of a linear characteristic air-fuel ratio sensor.
- the output current Ip at the interelectrode voltage Vs is expressed as Ip (Vs), (Ip (0.7 volts) ⁇ Ip (0.45 volts)) / Ip (0.45 volts) ⁇ 0. .05 and
- FIG. 6 shows the relationship between the output current Ip and the interelectrode voltage Vs at various air-fuel ratios of the downstream sensor 27d of the embodiment according to the present invention.
- curves Ca, Cb, Cc, Cd, Ce, Cf, Cg, Ch, and Ci have air-fuel ratios of 12, 13, 14, theoretical air-fuel ratio (14.6), 15, 18, 25, and 40, respectively.
- the output current Ip when maintained is shown.
- a curve Cj indicates the output current Ip when the exhaust gas side electrode 55 is in contact with the atmosphere. As can be seen from FIG. 6, the output current Ip increases as the air-fuel ratio increases.
- FIG. 7 shows the relationship between the air-fuel ratio AF and the output current Ip when the interelectrode voltage Vs is maintained at the reference voltage Vr in the downstream sensor 27d of the embodiment according to the present invention.
- the output current Ip increases as the air-fuel ratio AF increases.
- the output current Ip becomes the reference current Is (> 0).
- the reference air-fuel ratio is the stoichiometric air-fuel ratio.
- the oxygen concentration or air-fuel ratio in the exhaust gas can be detected from the output current Ip of the downstream sensor 27d. Therefore, in the embodiment according to the present invention, when the output current Ip is smaller than the reference current Is, it is judged that the air-fuel ratio AF is smaller than the theoretical air-fuel ratio AFS, that is, richer than the theoretical air-fuel ratio AFS, and the output current Ip is When larger than the reference current Is, it is determined that the air-fuel ratio AF is larger than the theoretical air-fuel ratio AFS, that is, leaner than the theoretical air-fuel ratio AFS.
- the air-fuel ratio is controlled based on the determination result. For example, when it is determined that the air-fuel ratio AF is smaller than the stoichiometric air-fuel ratio AFS based on the output current Ip of the downstream sensor 27d, the air-fuel ratio AF is controlled to increase. On the other hand, when it is determined that the air-fuel ratio AF is larger than the stoichiometric air-fuel ratio AFS based on the output current Ip of the downstream sensor 27d, the air-fuel ratio AF is controlled to be small. In this example, the air-fuel ratio AF is controlled using the theoretical air-fuel ratio AFS, that is, the reference air-fuel ratio as a target value. The air-fuel ratio AF is controlled, for example, by controlling the fuel injection amount or the intake air amount.
- the reference voltage Vr is set so that the change of the output current Ip with respect to the air-fuel ratio AF becomes large in the vicinity of the reference air-fuel ratio. In this way, it is possible to more accurately detect whether the air-fuel ratio AF is smaller or larger than the reference air-fuel ratio.
- FIG. 8 shows a routine for executing the above-described air-fuel ratio control.
- step 101 it is determined whether or not the output current Ip of the downstream sensor 27d is smaller than the reference current Is.
- the routine proceeds to step 102 where control is performed so that the air-fuel ratio becomes large.
- the routine proceeds to step 103 where control is performed so that the air-fuel ratio becomes smaller.
- FIG. 9A shows the output current Ip when the temperature of the downstream sensor 27d is relatively low
- FIG. 9B shows the output current Ip when the temperature of the downstream sensor 27d is relatively high.
- the output current Ip increases as the temperature of the downstream sensor 27d increases. For this reason, if the air-fuel ratio is detected based on the constant reference current Is, there is a risk of erroneous detection.
- the reference current Is is set based on the temperature Ts of the downstream sensor 27d. Specifically, as shown in FIG. 10, the reference current Is is set to increase as the temperature Ts of the downstream sensor 27d increases. As a result, the air-fuel ratio can be accurately detected regardless of the temperature Ts of the downstream sensor 27d, and therefore the air-fuel ratio can be accurately controlled.
- the reference current Is is stored in advance in the ROM 32 in the form of a map shown in FIG.
- FIG. 11 shows a routine for executing air-fuel ratio control according to another embodiment of the present invention.
- step 100a the temperature Ts of the downstream sensor 27d is detected.
- the reference current Is is calculated from the map of FIG.
- step 101 it is determined whether or not the output current Ip of the downstream sensor 27d is smaller than the reference current Is.
- Ip ⁇ Is the routine proceeds to step 102 where control is performed so that the air-fuel ratio becomes large.
- Ip ⁇ Is the routine proceeds to step 103 where control is performed so that the air-fuel ratio becomes smaller.
- the reference voltage Vr is set so that the reference current Is has a positive value.
- the reference voltage Vr is set so that the reference current Is becomes zero. In this way, the detection error is reduced.
- FIG. 12A shows the relationship between the output current Ip and the interelectrode voltage Vs when the temperature Ts of the downstream sensor 27d is relatively low
- FIG. 12B shows the output current Ip and the interelectrode voltage when the temperature of the downstream sensor 27d is relatively high. The relationship with the voltage Vs is shown.
- FIGS. 12A and 12B when the temperature of the downstream sensor 27d increases, the reference voltage Vr at which the output current Ip becomes zero decreases. For this reason, if the air-fuel ratio is detected based on the output current Ip detected while applying the constant reference voltage Vr, there is a risk of erroneous detection.
- the reference voltage Vr is set based on the temperature Ts of the downstream sensor 27d. Specifically, as shown in FIG. 13, the reference voltage Vr is set to decrease as the temperature Ts of the downstream sensor 27d increases. As a result, the air-fuel ratio can be accurately detected regardless of the temperature Ts of the downstream sensor 27d, and therefore the air-fuel ratio can be accurately controlled.
- the reference voltage Vr is stored in advance in the ROM 32 in the form of a map shown in FIG.
- FIG. 14 shows a routine for executing the reference voltage control of still another embodiment according to the present invention.
- step 200a the temperature Ts of the downstream sensor 27d is detected.
- the reference voltage Vr is calculated from the map of FIG.
- the interelectrode voltage Vs is maintained at the reference voltage Vr calculated in this way.
