Abstract

resumo "controle de um freio de liberação de compressão" um método e um sistema são descritos para um freio de liberação de com-pressão em um motor compreendendo uma tubulação de exaustão conectada a uma turbina fornecida com uma geometria de turbina variável onde a dita turbina é adicionalmente conectada a uma válvula de pressão de retorno para controlar a queda de pressão através da dita turbina onde o método compreende as etapas de: controlar a dita válvula de pressão de retorno com base em uma velocidade de motor medida e uma energia de frenagem desejada; calcular uma pressão de gás de tubulação de exaustão desejada com base na dita velocidade de motor medida e na dita energia de frenagem desejada; e, controlar a dita geometria de turbina variável de modo que a diferença entre uma pressão de gás de tubulação de exaustão medida e a dita pressão de gás de tubulação de exaustão desejada calculada seja minimizada.
