Abstract

patente de invenção: processo e dispositivo para testar um injetor de combustível. a presente de invenção refere-se a um processo para selecionar um método para determinar o tempo de injeção de processos de injeção individuais de um injetor de combustível (2) que pode ser abastecido com combustível sob pressão através de uma linha de alimentação (4), que compreende as seguintes etapas: etivação do injetor de combustível (2) que diferentes durações de ativação conhecidas em torno de um ponto de operação predefinido do injetor de combustível (2); determinação (100) de decurso da pressão temporal na linha de alimentação (4) para um número de processos de injeção: avaliação (200) dos decursos da pressão temporais determinados com pelo menos dois métodos diferentes (211, 212, 213) para determinar o tempo de injeção a partir do respectivo decurso da pressão; determinação da correção da correlação (221, 222, 223) entre os tempos de injeção determinados e a respectiva duração de ativação: seleção (230) do método com a maior correlação.
