Description

Technical Field

[0001] The invention relates to the technical field of diesel engine DPF regeneration, and in particular to a DPF regeneration control method, system, electronic equipment and storage medium. Background Art

[0002] In the existing technology, DPF technology can filter out most of the carbon smoke and ash particles in diesel engine exhaust to meet the requirements of National VI and future emission regulations. Since the initial capture efficiency of the new DPF carrier is low, it will only have high PN capture efficiency after the pores of the DPF carrier are filled with carbon deposits and ash and a filter layer is formed on the wall.

[0003] However, when the carbon load reaches a certain level, the DPF pressure difference will increase significantly, causing the engine combustion to deteriorate, and regeneration is needed to remove it. Ash cannot burn or oxidize, so ash can enable the particulate filter DPF to establish a stable particle capture capacity, but when the ash accumulation is small, a portion of carbon deposits still need to be retained to ensure PN capture capacity. Therefore, a DPF regeneration control method is urgently needed to ensure that PN meets regulatory requirements during the regeneration process, especially for particle capture with a particle size of less than 23nm.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] like Figure 1 As shown, the embodiment of the present application provides a DPF regeneration control method, comprising:

[0023] S1 obtains the total working time of the DPF from the fresh state to the current state requiring regeneration;

[0024] S2 determines the time length for the DPF to capture ash particles from the fresh state until the DPF establishes the PN capture capacity, and sets it as the standard time length;

[0025] S3 determines the regeneration control logic of the DPF according to the total working time and the standard time;

[0026] S4 controls DPF regeneration according to the DPF regeneration control logic;

[0027] The fresh state refers to a state in which there are no ash particles in the DPF.

[0028] Specifically, in the prior art, only when the pores of the DPF carrier are filled with carbon deposits or ash and a filter layer is formed on the wall, can the DPF have a high capture efficiency. However, when the carbon load reaches a certain level, the DPF pressure difference will increase significantly, causing the engine combustion to deteriorate, and it needs to be removed by regeneration. Ash cannot be burned or oxidized, so ash can enable the particle collector to establish a stable particle capture capacity.

[0029] The DPF is located between the DOC and SCR in the exhaust aftertreatment system. The DPF captures soot particles in the engine exhaust. The increase in soot particles will increase the flow resistance of the DPF. The DOC oxidizes the nitrogen monoxide in the exhaust into nitrogen dioxide. When the temperature before the DPF reaches above 300°C, the soot particles in the DPF react with the nitrogen dioxide gas, the soot particles are reduced, and the flow resistance of the DPF is reduced. The relationship between the flow resistance and the PN after the DPF during the DPF regeneration process: in the absence of ash, the PN after the DPF does not change significantly in the initial stage of regeneration as the flow resistance decreases. When the flow resistance is reduced to a certain extent, the PN increases rapidly and significantly, indicating that the particle capture capacity is greatly reduced and cannot be maintained after the carbon deposits are reduced; however, when there is ash, the PN after the DPF is maintained at a low level throughout the regeneration process.

[0030] The above technical solution of the present application can determine the regeneration control logic of the DPF according to the total working time of the DPF from the fresh state to the current state requiring regeneration and the time for the DPF to capture ash particles from the fresh state until the DPF establishes the PN capture capacity; the determination of the total working time of the DPF from the fresh state to the current state requiring regeneration and the time for the DPF to capture ash particles from the fresh state until the DPF establishes the PN capture capacity can determine whether the DPF can establish the PN capture capacity when the diesel engine needs to be regenerated, so as to judge whether the accumulation of ash particles during the DPF regeneration can ensure the PN capture capacity and then determine whether the DPF directly removes carbon deposits during regeneration to ensure that the PN meets the regulatory requirements during the regeneration process. Therefore, according to the determination of the regeneration control logic of the DPF according to the total working time of the DPF from the fresh state to the current state requiring regeneration and the time for the DPF to capture ash particles from the fresh state until the DPF establishes the PN capture capacity, it can provide a basis for ensuring that the PN meets the regulatory requirements during the regeneration process, improve the intelligence level of the DPF regeneration, and improve the practicality of the diesel engine.

[0031] It should be noted that the PN capture capacity described in this application, unless otherwise specified, means that the PN capture efficiency meets or exceeds the regulatory requirements.

[0032] As an optional implementation, the regeneration control logic of the DPF determined based on the total working time and the standard time includes: judging the relationship between the total working time and the standard time; if the total working time is greater than the standard time, controlling the DPF to not retain carbon deposits after regeneration; if the total working time is less than the standard time, controlling the DPF to retain carbon deposits for regeneration.

[0033] Specifically, when the total working time is longer than the standard time, the accumulated amount of ash can enable the DPF to have a stable and high capture efficiency, so it can be directly regenerated without retaining carbon deposits after the regeneration process.

[0034] As an optional implementation, if the total operating time is less than the standard time, controlling the DPF to retain carbon deposit regeneration includes: determining the DPF carbon deposition rate; judging the relationship between the DPF carbon deposition rate and a preset carbon deposition rate limit; and controlling the DPF to retain carbon deposition regeneration according to the relationship between the DPF carbon deposition rate and the preset carbon deposition rate limit.

[0035] Specifically, a higher carbon deposition rate means more soot particles are trapped in the DPF in the same period of time, and the time interval between regenerations is short, that is, the interval between two adjacent regenerations is short. Since the PN will increase during the regeneration process, fuel consumption is required for thermal management. In order to ensure that the PN of the regeneration process meets regulatory requirements and consumes the least fuel, the residual carbon load at the end of regeneration can be reasonably set according to the carbon deposition rate, that is, different regeneration flow resistances can be set.

[0036] The relative size of the carbon deposition rate can be limited by setting a preset carbon deposition rate limit. For example, when the carbon deposition rate is less than the preset carbon deposition rate limit, it can be considered that the carbon deposition rate is small, and the time interval between two regenerations is long. In this case, a smaller preset flow resistance can be set so that there is always relatively more carbon deposits in the DPF during and after the regeneration process to ensure the PN capture capacity of the DPF; for example, when the carbon deposition rate is greater than the preset carbon deposition rate limit, it can be considered that the carbon deposition rate is large, and the time interval between two regenerations is short. In this case, a larger preset flow resistance can be set so that there is relatively less carbon deposits in the DPF after the regeneration. Even if the residual carbon load is insufficient to ensure the PN capture capacity, the carbon deposition rate is fast, and the DPF can accumulate enough carbon soot in a short time after regeneration to maintain efficient PN capture capacity.

[0037] By properly setting the residual carbon load at the end of regeneration based on the total DPF usage time and carbon deposition rate, the DPF can maintain efficient PN capture capabilities and minimize fuel consumption.

[0038] It should be noted that the carbon deposition rate can be determined directly in the laboratory.

[0039] As an optional implementation, the control of DPF retaining carbon deposition regeneration based on the relationship between the DPF carbon deposition rate and the preset carbon deposition rate limit includes: if the DPF carbon deposition rate is less than the preset carbon deposition rate limit, controlling the DPF to regenerate with a first preset flow resistance; if the DPF carbon deposition rate is greater than the preset carbon deposition rate limit, controlling the DPF to regenerate with a second preset flow resistance; wherein the first preset flow resistance is less than the second preset flow resistance.

[0040] As an optional implementation, determining the time duration from when the DPF captures ash particles in the fresh state until the DPF establishes the PN capture capability includes: obtaining the time duration from when the DPF captures ash particles in the fresh state when the diesel engine is in a wear-free state until the DPF establishes the PN capture capability, and setting the time duration as the initial time duration; obtaining the actual mileage of the diesel engine; and correcting the initial time duration according to the actual mileage of the diesel engine to obtain the standard time duration.

[0041] As an optional implementation, the correction of the initial duration according to the actual mileage of the diesel engine includes: determining a revision coefficient according to the actual mileage of the diesel engine; and the standard duration is the product of the revision coefficient and the initial duration.

[0042] Specifically, since the engine consumes oil during normal operation, and the additives in the oil will form incombustible ash particles after combustion, the ash particles will also be captured by the DPF, and when the ash accumulation is sufficient, the DPF will also establish the PN capture capability. The time required for this process can be set to the standard time, and the standard time is set to T. As the diesel engine increases in use time, components such as the piston ring group and the cylinder liner will wear, resulting in an increase in the oil consumption level. If the diesel engine has not been replaced with components such as the piston ring group and the cylinder liner, the specific value of T will be affected by the actual mileage L of the diesel engine. The correction coefficient α can be determined as shown in Table 1, and the calculation formula is T=T0*α, where T0 is the time for the DPF to capture ash particles from the fresh state until the DPF establishes the PN capture capability when the diesel engine is in a non-wear state.

[0046] As an optional implementation, determining the DPF carbon deposition rate includes: obtaining the total transient duration of the diesel engine running in a continuous transient condition during a regeneration cycle; determining the increased mass of the DPF during a regeneration cycle; and determining the DPF carbon deposition rate based on the total transient duration and the increased mass of the DPF.

[0047] The total duration of the engine running in continuous transient conditions is t. The mass increase of DPF can be determined by weighing as m, where m is the total mass of soot particles captured within time t, and the carbon deposition rate is m / t.
