Abstract

DETECçãO DE SOBRECARGA EM TURBOCOMPRESSOR A presente invenção refere-se a um método de detecção de sobrecarga em um turbocompressor, cujo método pode incluir as etapas de medir uma velocidade de fluxo de ar através de um compressor de um turbocompressor; medir uma temperatura do fluxo de ar; calcular uma velocidade do fluxo de massa padrão de fluxo de ar na velocidade e na temperatura; medir uma proporção de pressão ao longo do compressor do turbocompressor; calcular uma velocidade de fluxo de massa de sobrecarga em uma linha de sobrecarga do compressor, na proporção de pressão; comparar a velocidade de fluxo de massa padrão com a velocidade de fluxo de massa da sobrecarga; e diminuir um fluxo de EGR ou reduzir a proporção de pressão mediante abertura de uma pá de hélice do compressor se a velocidade de fluxo de massa padrão for inferior à velocidade de fluxo de massa da sobrecarga.
