Abstract

método para monitorar um sistema scr. método para detectar se um injetor com uma válvula controlada por um sinal de modulação por largura de pulso (pwm, pulse width modulation) se encontra pelo menos parcialmente entupido, sendo que referido sistema compreende uma bomba, de preferência, uma bomba de deslocamento positivo, impelida por um motor, e cuja pressão é controlada por uma unidade de comando que mede continuamente a pressão e/ou outro parâmetro característico da energia transmitida pelo motor à bomba, de acordo com o que, durante a operação normal do sistema scr, porções específicas de uma destas medições são comparadas com porções equivalentes armazenadas em uma memória.
