Definitions
- the present invention relates to an exhaust gas recirculation control device and an exhaust gas recirculation control method for an internal combustion engine.
- EGR exhaust gas recirculation
- the EGR device includes an EGR passage that branches from the exhaust passage and merges with the intake passage, and an EGR valve that opens and closes the flow path of the EGR passage.
- the EGR valve opens according to the target EGR rate, and the exhaust
- the configuration is such that EGR gas flows to the intake side using the differential pressure between the intake side and the intake side.
- the controller sets a target EGR rate in the operating state of the internal combustion engine, and controls the ignition timing according to the target EGR rate. Therefore, when the amount of EGR gas that actually passes through the EGR valve (actual EGR gas amount) is smaller than the target EGR gas amount, knocking occurs when the engine is operated at the ignition timing corrected on the assumption that the target EGR rate is reached. May occur.
- the above-described deviation between the target EGR gas amount and the actual EGR gas amount is likely to occur when the differential pressure between the exhaust side and the intake side is small.
- the pressure loss becomes smaller. For example, when the EGR valve is opened while the exhaust system is cold, the difference between the exhaust side and the intake side is low because the pressure of the exhaust passage is low. The pressure is reduced.
- the smaller the intake air amount the smaller the exhaust flow rate, making it difficult for the pressure on the exhaust side to increase.
- the same EGR rate is set regardless of the engine speed if the load is the same without considering the intake air amount. For example, the low rotation and high load region, that is, the load is high. However, in a region where the intake air amount is small, knocking due to the difference between the target EGR gas amount and the actual EGR gas amount is likely to occur.
- an object of the present invention is to provide an EGR control device that controls the EGR device so that the occurrence of knocking can be suppressed even when the difference between the target EGR rate and the actual EGR rate is likely to occur.
- the exhaust gas recirculation control device is configured to remove a part of the exhaust gas of the internal combustion engine from the exhaust passage downstream of the turbine of the turbocharger and from the compressor of the turbocharger.
- An exhaust gas recirculation passage that recirculates to the intake passage upstream of the intake air flow and downstream of the air flow meter, and a recirculation control valve that adjusts the amount of exhaust gas recirculated to the intake air passage.
- the exhaust gas recirculation control device has a recirculation rate setting means for setting a lower target recirculation rate as the intake air amount of the internal combustion engine is smaller, and controls the opening degree of the recirculation control valve according to the target recirculation rate. To do.

- FIG. 2 is a diagram illustrating an example of the target EGR rate map.
- FIG. 3 is a diagram illustrating an example of a target EGR rate map according to the present embodiment.
- FIG. 4 is a diagram illustrating another example of the target EGR rate map according to the present embodiment.
- FIG. 1 is a configuration diagram of an internal combustion engine system to which an embodiment of the present invention is applied.
- an air flow meter 3 In the intake passage 2 of the internal combustion engine 1, an air flow meter 3, a compressor 4A of the turbocharger 4, a throttle chamber 5, and a collector tank 6 on the intercooler integrated side are arranged from the upstream side of the intake flow.
- the system includes a recirculation passage 13 that communicates the upstream side and the downstream side of the compressor 4A, and a recirculation valve 14 that opens during deceleration to return intake air from the downstream side to the upstream side of the compressor 4A.
- the turbine 4B, the manifold catalyst 8, and the underfloor catalyst 9 of the turbocharger 4 are arranged in the exhaust passage 7 from the upstream side of the exhaust flow.
- the present system includes a bypass passage 15 that communicates the upstream side and the downstream side of the turbine 4B, and a valve 16 that opens and closes the flow path of the bypass passage 15.
- the manifold catalyst 8 and the underfloor catalyst 9 are both exhaust purification catalyst devices.
- the manifold catalyst 8 is arranged at a position close to the downstream side of the turbine 4B so that the exhaust gas flows in as high as possible.
- the underfloor catalyst 9 has a larger capacity than the manifold catalyst 8 and is disposed under the floor of the vehicle.
- the system also includes an exhaust gas recirculation device (hereinafter also referred to as an “EGR device”).
- the EGR device branches from between the manifold catalyst 8 and the underfloor catalyst 9 in the exhaust passage 7 and joins the exhaust recirculation passage (hereinafter referred to as “the flow passage 3” upstream of the compressor 4A and downstream of the air flow meter 3 of the intake passage 2).
- a recirculation valve hereinafter also referred to as “EGR valve” 11 for adjusting the amount of exhaust gas (hereinafter also referred to as “EGR gas”) passing through the EGR passage 10. Consists of.
- an EGR gas cooler 12 that cools the EGR gas may be included.
- the EGR device of the present embodiment is a so-called low pressure EGR device that recirculates a part of the exhaust gas from the downstream side of the turbine 4B to the upstream side of the compressor 4A and the downstream side of the air flow meter 3.
- the internal combustion engine system described above further includes a crank angle sensor 18 that detects the rotational speed of the internal combustion engine 1 (hereinafter also referred to as the engine rotational speed) and an accelerator pedal opening sensor 19, and these sensors and the air flow meter 3. Is detected by the controller 100.
- the controller 100 executes ignition control, fuel injection control, throttle valve opening control, EGR device control (EGR control), and the like based on the read detection value.
- EGR control EGR device control
- the controller 100 first determines the target EGR rate by map search or the like based on the operating state (for example, engine speed and load), and controls the EGR valve 11 to an opening degree corresponding to the target EGR rate. A method for setting the target EGR rate will be described later.
- the opening degree of the EGR valve 11 corresponding to the target EGR rate is obtained by mapping the relationship between the target EGR rate and the opening degree of the EGR valve 11 in advance and searching this map.
- the controller 100 After determining the target EGR rate, the controller 100 sets the ignition timing based on the target EGR rate.
- FIG. 2 is a diagram showing an example of a known target EGR map.
- the target EGR rate is set from the viewpoint of knocking prevention and fuel efficiency improvement. If the load is the same, the target EGR rate is the same regardless of the engine speed, and the engine speed is the same. The target EGR rate increases as the load increases.
- the EGR device recirculates exhaust gas to the intake side using the differential pressure between the exhaust side and the intake side.
- the differential pressure between the exhaust side and the intake side is likely to increase because the intake side has a negative pressure.
- the low pressure EGR device since the intake side is atmospheric pressure, the lower the pressure on the exhaust side, the smaller the differential pressure, making it difficult to recirculate the exhaust gas.
- the pressure loss of the exhaust system decreases as the temperature of the exhaust system (manifold catalyst 8, underfloor catalyst 9, exhaust passage itself, etc.) decreases, the pressure in the exhaust passage 7 is difficult to increase when the exhaust system is at a low temperature.
- the amount of intake air decreases, and the exhaust flow rate decreases accordingly, making it difficult to increase the pressure on the exhaust side. As a result, differential pressure is less likely to occur.
- the target EGR rate is achieved because the differential pressure is small.
- the amount of EGR gas required for the recirculation is not recirculated, and the actual EGR rate becomes lower than the target EGR rate.
- the ignition timing is controlled to be advanced as the target EGR rate is larger, assuming that an EGR gas amount that can suppress the occurrence of knocking is introduced. Therefore, the larger the target EGR rate, the more likely knocking occurs when the target EGR rate and the actual EGR rate deviate.
- knocking is likely to occur in the low rotation high load region, particularly when the exhaust system is at a low temperature.
- knocking occurs, not only the deterioration of the internal combustion engine 1 is promoted, but in the case of a high-octane fuel specification vehicle, it is erroneously assumed that regular fuel is used even though high-octane fuel is used in the fuel property determination. May be judged.
- the ignition timing is retarded so that knocking does not occur even with regular fuel, and the output of the internal combustion engine 1 decreases, so that regions other than the low rotational speed region where knocking is difficult to occur The drivability will be reduced.
- the EGR rate set in the EGR map of FIG. 2 is a value that does not cause knocking even if there is a difference between the target EGR rate and the actual EGR rate, that is, the exhaust system is at a low temperature. There is a method to make it a small value on the assumption of.
- the target EGR rate is set, in a region where the differential pressure is likely to increase due to a large amount of intake air, such as in a high rotation region, the target EGR rate is smaller than necessary, and the fuel efficiency improvement effect by EGR control is reduced. It gets smaller.
- the target EGR rate is set as described below.
- FIG. 3 is a target EGR rate map used in this embodiment.
- the target EGR rate increases as the engine rotational speed increases at the same load, and the target EGR rate increases as the load increases at the same engine rotational speed.
- the curve which shows each EGR rate of FIG. 3 corresponds with an equal intake air amount curve. That is, in the target EGR rate map of FIG. 3, the target EGR rate based on the intake air amount is set. The larger the intake air amount, the larger the target EGR rate, and the smaller the intake air amount, the smaller the target EGR rate. ing.
- the air flow meter 3 causes the controller 100 so that the target EGR rate set in the target EGR rate map of FIG. 2 becomes the target EGR rate shown in the target EGR rate map of FIG. You may correct
- the smaller the intake air amount the larger the correction amount for reducing the target EGR rate.
- the larger the intake air amount the larger the correction amount for increasing the target EGR rate.
- the target EGR rate map of FIG. 3 has a lower target EGR rate in the low rotation speed region and a target in the high rotation speed region than the target EGR rate map of FIG.
- the EGR rate is increasing.
- the target EGR rate in the low rotation speed region is small, the target EGR rate can be easily achieved even if the differential pressure between the exhaust side and the intake side is small. Therefore, knocking in the low rotation and high load region as described above occurs. It becomes difficult to do.
- the target EGR rate map is not limited to that shown in FIG. 3, and the target EGR rate may be changed stepwise for each predetermined intake air amount range.
- the operation region is divided into region A, region B, and region C according to the intake air amount, and each region has a uniform target EGR rate, and a region with a larger intake air amount has a larger target.
- a map in which the EGR rate is set may be used.
- the target EGR rate map is such that the target EGR rate changes stepwise for each predetermined intake air amount range, the target EGR rate will not fluctuate if the operating state change amount is small. That is, fluctuations in the target EGR rate during operation are reduced. Thereby, it is possible to avoid complication of the ignition timing correction and the opening / closing operation of the EGR valve 11 accompanying the change in the target EGR rate.
