| description | As various operating statuses, exhaust air pressure P, exhaust air temperature TU and TD at the upstream and downstream of DPF, rotating speed Ne, load Q, and intake air flow rate F are each read to acquire the amount of PM arising during a minimal time period ?t, and the value obtained by adding the acquired amount to the amount m of accumulated PM is made an initial amount of accumulation. Further, exhaust air property and spatial velocity SV are obtained from the various operating statuses, and the amount m of accumulated PM after elapse of the minimal time period ?t is estimated from an equation for estimating the amount of accumulated PM: m=m*exp(-B*?t) derived in consideration of determined exhaust air property and spatial velocity SV. Subsequently, if the amount m of accumulated PM is not less than a specified value, the amount m of accumulated PM is reset to 0 after execution of forced regeneration process of the DPF.
On lit les différentes variables de fonctionnement telles que la pression du gaz d'échappement P, les températures du gaz d'échappement TU et TD en amont et en aval du filtre DPF, la vitesse de rotation Ne, la charge Q et le débit d'entrée F, pour acquérir la quantité de PM (matière particulaire) produite durant une période minimale ?t, et la valeur obtenue en ajoutant la quantité acquise à la quantité m de la PM accumulée est la quantité initiale d'accumulation. En outre on obtient les propriétés des gaz d'échappement et leur vitesse spatiale SV à partir de différentes conditions de fonctionnement, et on estime la quantité m de PM accumulée après écoulement de la période minimale ?t à partir d'une équation estimant la quantité de PM accumulée m=m*exp(-B*?t) dérivée en considérant les propriétés des gaz d'échappement et leur vitesse spatiale SV déterminées. En conséquence la quantité de PM accumulée n'est pas inférieure à une valeur spécifiée, et la quantité de PM accumulée est ramenée à zéro après exécution du processus forcé de régénération. |
