Abstract

método e dispositivo relacionados ao resfriamento de unidades de dosagem de sistemas de dosagem de hc. a invenção se refere a um método relativo a sistemas de dosagem de hc para limpeza de escapamento que compreende uma unidade de dosagem (250) para combustível, que compreende a etapa de descidir sobre uma necessidade, após a cessação de um fluxo de escapamento, de resfriar a dita unidade de dosagem de combustível por meio do combustível fornecido para esta, e a etapa de prever um padrão de temperatura da unidade de dosagem (250) como uma base para descidir sobre a dita necessidade, e prever, consequentemente, se uma temperatura predeterminada da unidade de dosagem (250) será atingida após a dita cessação do fluxo de escapamento . a invenção se refere, também, a um produto de programa de computador que contém um código de programa (p) para um computador (200; 200) para implementar um método, de acordo com a invenção. a invenção se refere, também, a um sistema de dosagem de hc e a um veículo a motor que é equipado com o sistema de dosagem de hc.method and device related to the cooling of dosage units of hc dosing systems. The invention relates to a method for exhaust cleaning hc metering systems comprising a fuel metering unit (250) comprising the step of descending upon a need, after cessation of an exhaust flow, of cooling said fuel metering unit by the fuel supplied thereto, and the step of predicting a metering unit temperature pattern (250) as a basis for descent upon said need, and thereby predicting whether a temperature dosage unit (250) will be reached after said cessation of exhaust flow. The invention also relates to a computer program product containing a program code (p) for a computer (200; 200) for implementing a method according to the invention. The invention also relates to an hc dosing system and a motor vehicle which is equipped with the hc dosing system.
