The high-load area refers to a high value of at least one of carbon loading capacity and ash loading capacity, the non-high-load area comprises an idle area and a partial carbon deposition area, wherein the idle area refers to a condition that both the carbon loading capacity and the ash loading capacity of the DPF are lower than certain limit values, no stable carbon layer or ash layer is built in the DPF at the moment, the PN trapping efficiency is very low, and the condition generally occurs in the fresh DPF, after the DPF is actively regenerated, after the DPF is cleaned, and the like; the partial carbon deposition area means that the ash loading amount in the DPF is lower than a certain limit value, but the carbon loading amount is within a preset range, at the moment, partial carbon deposition exists in the DPF, but the carbon deposition amount is not enough, and at the moment, if the whole vehicle and the engine operate in a high exhaust temperature area (for example, the exhaust temperature of aftertreatment is higher than 350 ℃), the partial carbon deposition can be subjected to violent passive regeneration, so that the carbon deposition in the DPF burns, the carbon layer structure becomes loose quickly, and the PN emission can also exceed the standard easily.
Compared with the prior art, the PN discharge control method provided by the invention realizes closed-loop regulation and control of the running mode of the engine by detecting the ash loading amount and the carbon loading amount of the DPF in real time, so that the DPF is in a high-load area as soon as possible, the time of the DPF in the high-load area in the running process of the engine is prolonged as much as possible, the PN trapping efficiency of the DPF is ensured, and the purpose of controlling the PN discharge is achieved.
Preferably, in the above PN emission control method, when the amount of ash loaded inside the DPF is lower than a first preset amount of ash D and the amount of carbon loaded is lower than a first preset amount of carbon a, it is determined that the inside of the DPF is in an empty region, and the engine is controlled to enter the ash accumulation mode.

Further, the measurement of the ash loading amount of the DPF can be realized by detecting the pressure difference before and after the DPF is regenerated, and determining the ash loading amount in the DPF according to the pressure difference before and after the DPF, wherein the soot in the DPF is consumed after the DPF is regenerated, and the main reason for the pressure difference is the ash loading amount of the DPF.
Preferably, the above-mentioned over-temperature control mode includes adjusting an engine operation mode, and adjusting the engine operation mode includes controlling actions of actuators such as engine combustion, a supercharger, EGR, and the like, so as to make an engine exhaust temperature lower than a preset temperature value or make an engine exhaust temperature lower than 10% of a time that is higher than the preset temperature value within a preset time period.
In an embodiment of the invention, the preset temperature value is 350 ℃.
Preferably, the ash accumulation mode includes increasing the engine oil consumption rate, and the increase of the engine oil consumption rate can be achieved by controlling components such as an engine oil nozzle, a supercharger, an EGR and the like, so as to increase the fuel oil consumption rate, and the increase of the fuel oil consumption rate is often accompanied by the increase of the engine oil consumption rate, so that the rapid accumulation of the ash is achieved.
The embodiment of the invention also provides an engine PN emission control system used for the PN emission control method, and the control system comprises a particulate matter detection device, an engine oil consumption rate detection device and a control device, wherein the particulate matter detection device is used for detecting the content of particulate matter emitted by the original engine of the engine; the engine oil consumption rate detection device is used for detecting the engine oil consumption rate; the control device is respectively electrically connected with the particulate matter detection device and the engine oil consumption rate detection device, whether the carbon loading amount and the ash loading amount in the DPF are in a high-load area or not is judged according to detection values of the particulate matter detection device and the engine oil consumption rate detection device, and when the carbon loading amount and the ash loading amount in the DPF do not reach the high-load area, the engine is controlled to enter an ash accumulation mode or an over-temperature control mode.
