Abstract

1/1 resumo “método e dispositivo para detectar interrupções em um sistema de combustível” um dispositivo para o suprimento de combustível a partir de um tanque de combustível (1) para uma parte de alta pressão (2) de um sistema para injeção de combustível em um motor de combustão que tem no mínimo uma bomba operada eletricamente (10) arranjada em um conduto entre o tanque de combustível e a parte de alta pressão. dispositivo (17) é arranjado para medir o consumo de energia ia da bomba, bem como dispositivo (18) para medir a velocidade do motor da bomba. um dispositivo (16) compara a relação entre o consumo de energia medido e a velocidade do motor medida com valores assim chamados normais armazenados desta relação e equaciona discrepâncias que excedem um certo nível nesta comparação com detecção da ocorrência de um vazamento ou interrupção parcial ou total no conduto (7).1/1 summary “method and device for detecting interruptions in a fuel system” means a device for supplying fuel from a fuel tank (1) to a high pressure part (2) of a fuel injection system in a combustion engine having at least one electrically operated pump (10) arranged in a conduit between the fuel tank and the high pressure portion. device (17) is arranged to measure pump energy consumption as well as device (18) for measuring pump motor speed. a device (16) compares the relationship between measured energy consumption and measured motor speed with so-called normal stored values of this ratio and equates discrepancies exceeding a certain level in this comparison with detecting the occurrence of a leak or partial or total interruption. in the conduit (7).
