Determining a post-carbon clean initial GPF weight from the first initial GPF weight, the second initial GPF weight, and the third initial GPF weight, the post-carbon clean initial GPF weight being the initial GPF ash weight. For example, a GPF core temperature of 330 ℃ results in a post-carbon purge first initial GPF weight of M01The weight of the second initial GPF after carbon cleaning obtained at the central temperature of GPF of 300 ℃ is M02The weight of the third initial GPF after carbon cleaning is M, wherein the central temperature of the GPF is 280 DEG C03Then obtaining the initial GPF ash weight M0The calculation formula of (2) is as follows:
further, when the current mileage reaches a second preset mileage, acquiring a reference GPF ash weight corresponding to the second preset mileage, including:
when the driving mileage reaches a second preset mileage, acquiring a reference GPF weight corresponding to the second preset mileage; and acquiring a GPF carbon cleaning instruction, performing carbon cleaning treatment on the GPF in the test vehicle according to the GPF carbon cleaning instruction to obtain a reference GPF weight after carbon cleaning, and taking the reference GPF weight after carbon cleaning as a reference GPF ash weight.
It is easy to understand that when the current driving mileage reaches a second preset mileage, the detachable GPF is weighed, so that the reference GPF weight of the GPF in the test vehicle is obtained, wherein the reference GPF weight comprises soot, ash and the like, the soot is solid micro-particles generated by incomplete combustion of gasoline in an engine cylinder, a GPF carbon cleaning instruction can be triggered by a user to enable the soot to be combusted, so that the reference GPF ash weight is obtained, when the GPF carbon cleaning instruction is obtained, the GPF in the test vehicle is subjected to carbon cleaning treatment according to the GPF carbon cleaning instruction, the GPF subjected to carbon cleaning is subjected to heat preservation weighing, so that the reference GPF weight subjected to carbon cleaning is obtained, the reference GPF weight subjected to carbon cleaning is used as the reference GPF ash weight, and finally the second preset mileage, the accumulated gasoline consumption corresponding to the second preset mileage and the target GPF ash weight generated by the GPF in the second preset mileage are subjected to data storage and tabulation operation, so that the GPF model test data of the GPF ash is obtained Table (7). For example, Table 1 below is a GPF ash model test data table, including mileage, cumulative gasoline consumption over mileage, and target GPF ash weight,
