Abstract
a presente invenção refere-se a um processo para determinação de uma taxa de injeção de uma válvula injetora (1), com ajuda de um modelo matemático, que tem como base valores de medição, que compreendem o curso (x) de um pistão (3), que limita uma câmara de medição (2), durante a injeção de um fluido de teste (4) na câmara de medição (2), sendo que é realizada uma correção da taxa de injeção na base de um valor de medição adicional. de acordo com a invenção, a pressão (pa) em um volume de adaptador (5), através do qual a válvula injetora (1) está conectada com a câmara de medição (2), é usado como valor adicional de medição para correção da taxa de injeção. além disso, é indicado um dispositivo para determinação de uma taxa de injeção de uma válvula injetora.
