Description

TECHNICAL FIELD

[0001] The present application relates to the field of diesel engine DPF regeneration technology, and particularly relates to a DPF regeneration control method and system, an electronic device and a storage medium. BACKGROUND

[0002] In the prior art, DPF technology can filter most of the particulate matters such as soot and ash in diesel engine exhaust gas to meet the requirements of the national sixth and future emission regulations. Since the initial trapping efficiency of the brand-new DPF carrier is low, only after the DPF carrier pores are filled with carbon and ash and a filter layer is formed on the wall surface, the DPF carrier has high PN trapping efficiency.

[0003] However, when the carbon load reaches a certain degree, the DPF pressure difference will increase significantly, resulting in deterioration of engine combustion, and regeneration is needed to remove it. Ash cannot be burned and oxidized, so ash can establish stable particle trapping capacity for the particulate filter DPF, but when the amount of accumulated ash is small, a part of the carbon still needs to be retained to ensure the PN trapping capacity. Therefore, there is an urgent need for a DPF regeneration control method to ensure that the PN meets the regulatory requirements during the regeneration process, especially for particles with a particle size of less than 23 nm.

[0020] In order to make the personnel in the technical field better understand the present application, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort should belong to the protection scope 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 do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, 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 "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

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

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

[0024] S2 determining the time length of DPF from capturing ash particles in the fresh state to establishing PN capture capacity of DPF, and setting it as a standard time length;

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

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

[0027] The fresh state is a state in which no ash particles are trapped in the DPF.

[0028] Specifically, in the prior art, only after the DPF carrier pores are filled with carbon or ash and a filter layer is formed on the wall surface, the DPF has high trapping efficiency. However, when the carbon load reaches a certain degree, the DPF pressure difference will increase significantly, resulting in engine combustion deterioration, and a regeneration method needs to be used to remove it. Ash cannot be burned and oxidized, so ash can make the particulate trap establish stable particulate trapping capacity.

[0029] The DPF is located between the DOC and the SCR in the exhaust aftertreatment system. The DPF traps soot particles in the engine exhaust, and an increase in soot particles will increase the flow resistance of the DPF. The DOC oxidizes the nitrogen monoxide in the exhaust to nitrogen dioxide. When the temperature before the DPF reaches 300 DEG C or above, the soot particles in the DPF react with the nitrogen dioxide gas, and the soot particles decrease, and at the same time the flow resistance of the DPF decreases. 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, and when the flow resistance decreases to a certain degree, the PN increases rapidly and significantly, indicating that the particulate trapping capacity is greatly reduced after the carbon is reduced and cannot be maintained; however, with ash, the PN after the DPF remains at a low level throughout the regeneration process.

[0030] The above technical solution of the present application can determine the DPF regeneration control logic according to the total working time of the DPF from the fresh state to the current regeneration state and the time of the DPF from trapping ash particles in the fresh state to establishing the PN trapping capacity. The determination of the total working time of the DPF from the fresh state to the current regeneration state and the time of the DPF from trapping ash particles in the fresh state to establishing the PN trapping capacity can determine whether the DPF can establish the PN trapping capacity when the diesel engine needs to be regenerated, so as to determine whether the accumulation of ash particles can guarantee the PN trapping capacity when the DPF is regenerated, and further determine whether the PN can meet the regulatory requirements during the regeneration process after the carbon is directly removed during the regeneration process. Therefore, according to the determination of the DPF regeneration control logic according to the total working time of the DPF from the fresh state to the current regeneration state and the time of the DPF from trapping ash particles in the fresh state to establishing the PN trapping capacity, an implementation basis is provided for guaranteeing that the PN meets the regulatory requirements during the regeneration process, the intelligent degree of the DPF regeneration is improved, and the practicability of the diesel engine is improved.

[0031] It is to be noted that the PN trapping capability in the present application refers to the trapping efficiency of PN reaching or being higher than the regulatory requirements, unless otherwise specified.

[0032] As an optional implementation, the regeneration control logic of the DPF according to the total working time length and the standard time length comprises: determining the size relationship between the total working time length and the standard time length; if the total working time length is greater than the standard time length, controlling the DPF to not retain the accumulated carbon after regeneration; and if the total working time length is less than the standard time length, controlling the DPF to retain the accumulated carbon for regeneration.

[0033] Specifically, when the total working time length is greater than the standard time length, the accumulated amount of ash can make the DPF have stable and high trapping efficiency, and thus the DPF can be directly regenerated without retaining the accumulated carbon after the regeneration process.

[0034] As an optional implementation, if the total working time length is less than the standard time length, the DPF is controlled to retain the accumulated carbon for regeneration, which comprises: determining the DPF accumulated carbon rate; determining the size relationship between the DPF accumulated carbon rate and a preset accumulated carbon rate limit value; and controlling the DPF to retain the accumulated carbon for regeneration according to the size relationship between the DPF accumulated carbon rate and the preset accumulated carbon rate limit value.

[0035] Specifically, a high accumulated carbon rate represents that more soot particles are trapped in the DPF in the same time, and the time interval between adjacent two regenerations is short. Since the PN increases during the regeneration process and fuel is consumed for thermal management, the residual carbon load at the end of regeneration can be reasonably set according to the accumulated carbon rate, that is, different regeneration flow resistances are set.

[0036] The relative size of the accumulated carbon rate can be limited by setting the preset accumulated carbon rate limit value. For example, when the accumulated carbon rate is less than the preset accumulated carbon rate limit value, the accumulated carbon rate is considered to be small, and the time interval between two regenerations is long. Therefore, a smaller preset flow resistance can be set to ensure that the DPF always has relatively more accumulated carbon during and after the regeneration process to ensure the PN trapping capability of the DPF. For example, when the accumulated carbon rate is greater than the preset accumulated carbon rate limit value, the accumulated carbon rate is considered to be large, and the time interval between two regenerations is short. Therefore, a larger preset flow resistance can be set to make the DPF have relatively less accumulated carbon after regeneration, that is, the residual carbon load is insufficient to ensure the PN trapping capability at all times, but the accumulated carbon rate is fast, and the DPF can accumulate enough soot in a short time after regeneration to maintain high PN trapping capability.

[0037] By setting the residual carbon load at the end of regeneration according to the total duration of DPF usage and the carbon deposition rate, the DPF can maintain high PN trapping capacity and fuel consumption can be minimized.

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

[0039] As an optional embodiment, the method for controlling DPF regeneration according to the relationship between the DPF carbon deposition rate and the preset carbon deposition rate limit value comprises: if the DPF carbon deposition rate is less than the preset carbon deposition rate limit value, controlling the DPF to regenerate at a first preset flow resistance; if the DPF carbon deposition rate is greater than the preset carbon deposition rate limit value, controlling the DPF to regenerate at a second preset flow resistance; wherein the first preset flow resistance is less than the second preset flow resistance.

[0040] As an optional embodiment, the determination of the duration from the fresh state trapping of ash particles to the establishment of PN trapping capacity of the DPF comprises: obtaining the duration from the fresh state trapping of ash particles to the establishment of PN trapping capacity of the DPF of the diesel engine in a non-wearing state, and setting it as an initial duration; obtaining the actual mileage of the diesel engine; and correcting the initial duration according to the actual mileage of the diesel engine to obtain the standard duration.

[0041] As an optional embodiment, the correction of the initial duration according to the actual mileage of the diesel engine comprises: 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, the engine will consume engine oil during normal operation, and the combustion of additives in the engine oil will form non-combustible ash particles. The ash particles will be trapped by the DPF and will also establish the PN trapping capacity of the DPF when the amount of ash accumulation is sufficient. The duration required for this process can be set as the standard duration, and the standard duration can be set as T. As the diesel engine is used for a longer time, the piston ring set and cylinder liner and other components will wear out, resulting in an increase in engine oil consumption. If the diesel engine has not been replaced with a new piston ring set and cylinder liner, the specific value of T will be affected by the actual mileage L of the diesel engine. The determination of the revision coefficient a can be as shown in Table 1, and the calculation formula is T = T0* a, where T0 is the duration from the fresh state trapping of ash particles to the establishment of PN trapping capacity of the DPF of the diesel engine in a non-wearing state.
