摘要： A particulate filter ash loading prediction method including the steps of determining a service age for the particulate filter; calculating an ash accumulation rate in the particulate filter; determining a maximum service age for the particulate filter dependent upon the ash accumulation rate; and comparing the service age to the maximum service age. If the service age exceeds the maximum service age then indicating that a service and/or replacement of the particulate filter is needed due to ash loading.

摘要： In an exhaust emission purification method and an exhaust emission purification system where forced regeneration start timing of a DPF for purifying the PM (particulate matters) in exhaust gas is judged based on the comparison of a differential pressure across the DPF with a predetermined differential pressure threshold across the DPF, a differential pressure threshold (ΔPs) across the DPF is set by multiplying a reference differential pressure threshold (ΔPs0) across the DPF by a coefficient (α(ΔM)) which varies stepwise or continuously depending on the mileage (ΔM) of a vehicle after previous forced regeneration. Consequently, the PM can be removed by burning while the amount of PM accumulated unevenly in the DPF is still small, and excessive temperature rise in the DPF resulting from excessive accumulation of PM during forced regeneration and melting-loss of DPF due to excessive temperature rise can be prevented.

摘要： An exhaust emission control system [1] comprising a continuous regenerating DPF [13] and a DPF controlling means [30C], wherein control is so performed as to accept the operation of a forced regenerating means [34C] at an operation request by a driver when it is judged a traveling distance [ΔMc] after starting collection detected by a traveling distance detecting means [33C] has reached a specified judging traveling distance [ΔM1] even when the DPF controlling means [30C] detects a collection amount [ΔPm] detected by a collection amount detecting means [32C] is smaller than a specified judging collection amount [ΔP1]. Accordingly, in a continuous regenerating DPF [13] capable of manual regenerating, the number of warning such as a blinking regeneration button prompting a manual regeneration is reduced to relieve a driver of trouble.

摘要： The disclosure relates to a DPF regeneration trigger control method and terminal device, and a storage medium. The method includes: setting an active trigger differential pressure and an initial trigger differential pressure; and controlling, according to a relationship between a differential pressure of the DPF collected in real time during a vehicle travelling process and the active trigger differential pressure and a relationship between the differential pressure of the DPF and the initial trigger differential pressure, the vehicle to actively start DPF regeneration, to trigger passive DPF regeneration, or not to start DPF regeneration; otherwise, controlling the vehicle to actively start DPF regeneration. According to the disclosure, by setting a flexible trigger interval, there is a tolerance interval of differential pressure, so that fuel consumption of the diesel engine can be reduced, and the economy is improved.

摘要： A computer-implemented method for controlling a regeneration event for an exhaust aftertreatment system of a vehicle is described. The method comprises predicting, by a processor device, expected travelling times for travelling from a starting point to a first destination point and from an auxiliary point to a second destination point based on collected drive time statistical data and collected additional drive time statistical data; and controlling, by the processor device, the regeneration event based on the predicted expected travelling times.
