Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas aftertreatment, and particularly relates to a method, device and electronic device for treating particulate matter. Background Art

[0002] At present, for models of non-road stage-IV construction machinery with many transient working conditions, the working conditions are also relatively complex. For example, when operating at maximum efficiency, the exhaust gas temperature in front of the DPF (Diesel Particulate Filter) is relatively high, and the carbon deposit growth is slow; however, when operating at partial efficiency, the exhaust gas temperature in front of the DPF is relatively low, and the carbon deposit growth is rapid. Moreover, once the vehicle engine is in a working condition with rapid carbon deposit growth for a long time, it will lead to frequent regeneration and increase the risk of oil dilution. Therefore, it is difficult to accurately control the vehicle for DPF regeneration in related technologies, resulting in poor effect of removing carbon particulate matter in the DPF.

[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] For the convenience of description, some nouns or terms related to the embodiments of the present application are explained below:

[0052] DOC: Diesel Oxide Catalyst, installed in front of the DPF (Diesel Particulate Filter), used to oxidize NO (nitric oxide) in the exhaust gas to NO2 (nitrogen dioxide), and at the same time increase the exhaust gas temperature to assist the normal operation of the DPF (Diesel Particulate Filter) and SCR (Selective Catalytic Reduction System).

[0053] DPF: Diesel Particulate Filter, used to trap particulate matter in the exhaust gas. When the mass of the trapped particulate matter reaches a certain level, passive regeneration or active regeneration is required to restore the particulate matter trapping ability of the DPF (Diesel Particulate Filter).

[0054] DPF regeneration: Utilize the principle of the reaction between NO2 (nitrogen dioxide) generated in the DOC (Diesel Oxide Catalyst) and C (carbon) to eliminate C (carbon) in the DPF (Diesel Particulate Filter).

[0055] Parked vehicle regeneration: The whole vehicle is parked in place, and diesel is injected into the exhaust pipe. The diesel oxidizes and releases heat in the DOC, burning the carbon particles inside the DPF.

[0056] In - vehicle regeneration: During driving, diesel is injected into the exhaust pipe. The diesel oxidizes and releases heat in the DOC, burning the carbon particles inside the DPF.

[0057] The present invention will be described below in conjunction with preferred implementation steps. Figure 1 It is a flow chart of a method for treating particulate matter provided according to an embodiment of the present application. Figure 1 As Figure 1 shown, the method includes the following steps:

[0058] Step S101, obtain the number information of times of eliminating target particulate matter in a particulate matter trap within a preset time period, where the particulate matter trap is a machine in a target vehicle for trapping target particulate matter, and the target particulate matter is particulate matter in the exhaust gas emitted by the target vehicle.

[0059] For example, identify the number of times of on-road regeneration and off-road regeneration performed by the engine of the target vehicle (corresponding to the number information of times of eliminating target particulate matter in the particulate matter trap) within a certain time (corresponding to the above-mentioned preset time period).

[0060] For instance, the above-mentioned target particulate matter can be C (carbon) particulate matter, and the above-mentioned number of regeneration times represents the number information of times of eliminating C (carbon) in the DPF (diesel particulate filter).

[0061] Step S102, determine the state information of the target particulate matter in the engine of the target vehicle based on the number information of times of eliminating the target particulate matter in the particulate matter trap within a preset time period.

[0062] For example, according to the number of times of on-road regeneration and off-road regeneration performed by the engine (corresponding to the number information of times of eliminating target particulate matter in the particulate matter trap) identified within a certain time (corresponding to the above-mentioned preset time period), identify which carbon deposition state (i.e., the state information of the target particulate matter) the engine (corresponding to the engine of the target vehicle) is in. Moreover, the engine carbon deposition state (i.e., the state information of the target particulate matter) can be divided into three states: excessive carbon deposition, carbon deposition balance, and less carbon deposition.

[0063] Step S103, perform an elimination process on the target particulate matter in the particulate matter trap according to the state information of the target particulate matter in the engine, and realize the regeneration process of the particulate matter trap.

[0064] For example, according to the identified carbon deposition state (i.e., the state information of the target particulate matter) of the engine (corresponding to the engine of the target vehicle), the regeneration measures can be adjusted.

[0065] Through the above steps S101 to S103, by identifying the number of regenerations (i.e., the number of times of eliminating the target particulate matter in the particulate filter) performed by the target vehicle within a certain time (i.e., the preset duration), the carbon deposition state of the engine of the target vehicle (i.e., the state information of the target particulate matter) is identified. Then, according to the carbon deposition state of the engine, a regeneration measure (i.e., eliminating the target particulate matter in the particulate filter) is determined, so that the DPF regeneration of the vehicle can be accurately controlled, and further the effect of eliminating the carbon particulate matter in the DPF is improved.

[0066] Optionally, in the particulate matter processing method provided in the embodiment of the present application, obtaining the number of times of eliminating the target particulate matter in the particulate filter within the preset duration includes: obtaining the first number of times of eliminating the target particulate matter in the particulate filter by the target vehicle during driving within the preset duration; obtaining the second number of times of eliminating the target particulate matter in the particulate filter by the target vehicle during stopping within the preset duration; based on the first number and the second number, obtaining the number of times of eliminating the target particulate matter in the particulate filter within the preset duration.

[0067] For example, it is possible to identify the number of on-road regenerations (corresponding to the above first number) and the number of parked regenerations (corresponding to the above second number) performed by the engine within a certain time (corresponding to the above preset duration), and then add the number of on-road regenerations (corresponding to the above first number) and the number of parked regenerations (corresponding to the above first number) performed by the engine within a certain time together to obtain the number of regenerations (corresponding to the number of times of eliminating the target particulate matter in the particulate filter as described above) of the engine within this duration (corresponding to the above preset duration).

[0068] Through the above solution, the number of regenerations of the target vehicle within a certain time can be quickly and accurately obtained.

[0069] Optionally, in the particulate matter processing method provided in the embodiment of the present application, determining the state information of the target particulate matter in the engine of the target vehicle according to the number of times of eliminating the target particulate matter in the particulate filter within the preset duration includes: judging whether the number of times of eliminating the target particulate matter in the particulate filter within the preset duration is greater than a preset number; if the number of times of eliminating the target particulate matter in the particulate filter within the preset duration is greater than the preset number, determining that the state of the target particulate matter in the engine of the target vehicle is the first state, where the first state indicates that the mass of the target particulate matter in the engine of the target vehicle is greater than the preset mass; if the number of times of eliminating the target particulate matter in the particulate filter within the preset duration is not greater than the preset number, judging whether the number of times of eliminating the target particulate matter in the particulate filter within the preset duration is less than the preset number to obtain a judgment result; according to the judgment result, determining the state information of the target particulate matter in the engine of the target vehicle.

[0070] For example, the above preset number of times can be 3 times. When it is detected that the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is 5 times, then at this time, the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is greater than the preset number of times 3 times. Therefore, at this time, it can be determined that the engine of the vehicle (corresponding to the above target vehicle) is in a state of excessive carbon deposition (corresponding to the above first state); if it is detected that the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is not greater than the preset number of times 3 times, then it can be judged whether the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is less than the preset number of times 3 times, and then according to the judged result, it is determined which carbon deposition state the engine of the vehicle (corresponding to the above target vehicle) is in.

[0071] Through the above solution, according to the number of regeneration times of the target vehicle within a certain time, the state of excessive carbon deposition in the engine can be conveniently determined.

[0072] Optionally, in the method for treating particulate matter provided in the embodiments of the present application, according to the judgment result, determining the state information of the target particulate matter in the engine of the target vehicle includes: if the judgment result indicates that the number of times of eliminating the target particulate matter in the particulate matter trap within the preset duration is less than the preset number of times, then it is determined that the state of the target particulate matter in the engine of the target vehicle is the second state, where the second state means that the mass of the target particulate matter in the engine of the target vehicle is less than the preset mass; if the judgment result indicates that the number of times of eliminating the target particulate matter in the particulate matter trap within the preset duration is not less than the preset number of times, then it is determined that the state of the target particulate matter in the engine of the target vehicle is the third state, where the third state means that the mass of the target particulate matter in the engine of the target vehicle is equal to the preset mass.

[0073] For example, if the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is 2 times, then at this time, it can be determined that the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is less than the preset number of times 3 times. Therefore, at this time, the engine of the vehicle (corresponding to the above target vehicle) is in a state of less carbon deposition (corresponding to the above second state); if the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is 3 times, then at this time, it can be determined that the number of regeneration times of the target vehicle within a certain time (corresponding to the above preset duration) is equal to the preset number of times 3 times. Therefore, at this time, the engine of the vehicle (corresponding to the above target vehicle) is in a state of carbon deposition balance (corresponding to the above third state).

[0074] Through the above solution, the state of less carbon deposition and the state of carbon deposition balance in the engine can be quickly and accurately judged.

[0075] For example, Figure 2It is the flowchart of the method for treating particulate matter provided by the embodiments of the present application Figure 2 , such as Figure 2 shown, it is the method for treating particulate matter provided by the embodiments of the present application, which specifically includes the following steps:

[0076] Step S201, determine the status information of the target particulate matter in the engine of the target vehicle;

[0077] Step S202, if the status of the target particulate matter in the engine is the first status, raise the temperature of the particulate matter trap and perform elimination treatment on the target particulate matter in the particulate matter trap;

[0078] Step S203, if the status of the target particulate matter in the engine is the second status, lower the temperature of the particulate matter trap and perform elimination treatment on the target particulate matter in the particulate matter trap;

[0079] Step S204, if the status of the target particulate matter in the engine is the third status, prohibit adjusting the temperature of the particulate matter trap and perform elimination treatment on the target particulate matter in the particulate matter trap.

[0080] For example, when it is determined that the state is excessive carbon deposition (corresponding to the above-mentioned first state), adjust the regeneration measure, increase the exhaust gas temperature in front of the DPF (diesel particulate filter), and improve the decarbonization effect; when it is determined that the state is less carbon deposition (corresponding to the above-mentioned second state), adjust the regeneration measure, lower the exhaust gas temperature in front of the DPF (diesel particulate filter), and reduce the decarbonization effect; when it is determined that the state is carbon deposition balance (corresponding to the above-mentioned third state), maintain the regeneration measure.

[0081] Through the above solution, the regeneration measure of the DPF can be adjusted quickly and accurately.

[0082] For example, Figure 3 It is the flowchart of the method for treating particulate matter provided by the embodiments of the present application Figure 3 , specifically, it includes the following steps:

[0083] S301, obtain the number information of eliminating the target particulate matter in the particulate matter trap within a preset time period;

[0084] S302, determine the status information of the target particulate matter in the engine of the target vehicle according to the number information of eliminating the target particulate matter in the particulate matter trap within a preset time period;

[0085] S303, determine that the state is less carbon deposition;

[0086] S304, lower the exhaust gas temperature in front of the DPF;

[0087] S305, determine that the state is carbon deposition balance;

[0088] S306, Maintain the regeneration measure;

[0089] S307, Determine the state of excessive carbon deposition;

[0090] S308, Increase the exhaust gas temperature in front of the DPF.

[0091] In the embodiment of the present application, first, identify the number of on-road regenerations and parking regenerations performed by the engine within a preset duration, and then, based on the on-road and parking regeneration information within the preset duration, determine whether the engine is in one of the three states: the state of excessive carbon deposition (corresponding to the first state above), the state of carbon deposition balance (corresponding to the third state above), and the state of less carbon deposition (corresponding to the second state above). When it is determined that the engine is in the state of excessive carbon deposition (corresponding to the first state above), adjust the regeneration measure, increase the exhaust gas temperature in front of the DPF (Diesel Particulate Filter), improve the carbon elimination effect, reduce the number of regenerations, and thus reduce the risk of engine oil dilution. When it is determined that the engine is in the state of less carbon deposition (corresponding to the second state above), adjust the regeneration measure, reduce the exhaust gas temperature in front of the DPF (Diesel Particulate Filter), reduce the carbon elimination effect, and reduce the fuel injection amount, thereby improving the economy. When it is determined that the engine is in the state of carbon deposition balance (corresponding to the third state above), maintain the regeneration measure.

[0092] In this embodiment, by analyzing the on-road regenerations and parking regenerations within a certain period of time, change the injection amount of the post-injection, control the temperature of the DPF (Diesel Particulate Filter), adjust the carbon elimination effect in real time, and reduce the risk of engine oil dilution or improve the economy. This control method can improve the adaptability of the engine in actual applications.

[0093] In addition, in this embodiment, by collecting the regeneration situation of the engine in real time, it is judged whether the current regeneration temperature is suitable, in the case of excessive carbon deposition and excessive on-road regeneration times, improve the carbon elimination ability and reduce the number of regenerations, which can reduce the risk of engine oil dilution, and in the case of less carbon deposition, reducing the post-injection amount can improve the economy.

[0094] In summary, the particulate matter treatment method provided by the embodiments of the present application obtains the number information of times of eliminating target particulate matter in the particulate matter trap within a preset time period. Here, the particulate matter trap is a machine in the target vehicle for trapping target particulate matter, and the target particulate matter is the particulate matter in the exhaust gas emitted by the target vehicle. According to the number information of times of eliminating target particulate matter in the particulate matter trap within a preset time period, the state information of the target particulate matter in the engine of the target vehicle is determined. According to the state information of the target particulate matter in the engine, the target particulate matter in the particulate matter trap is eliminated, and the regeneration process of the particulate matter trap is realized, solving the problem in the related art that it is difficult to accurately control the vehicle to perform DPF regeneration, resulting in a poor effect of eliminating carbon particulate matter in the DPF. By identifying the number of regenerations (i.e., the number information of times of eliminating target particulate matter in the particulate matter trap) of the target vehicle within a certain time (i.e., the preset time period), it is identified which carbon deposition state (i.e., the state information of the target particulate matter) the engine of the target vehicle is in, and then according to the carbon deposition state of the engine, the regeneration measure (i.e., eliminating the target particulate matter in the particulate matter trap) is determined, so that the vehicle can be accurately controlled to perform DPF regeneration, thereby improving the effect of eliminating carbon particulate matter in the DPF.

[0095] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.
