Abstract

"CONTROLE DE UM TURBOCOMPRESSOR DE GEOMETRIA VARIáVEL PELA DETECçãO DA PRESSãO DE DESCARGA". é fornecido um sistema e método para utilização em uma contrapressão de descarga do motor (1210) para controlar um turbocompressor de geometria variável. O sistema de controle determina uma contrapressão de descarga desejada (1205) com base nos parâmetros do motor. A contra-pressão de descarga desejada (1205) é então comparada com uma contra-pressão de descarga medida (1210) para determinar a diferença (1215) entre as contra-pressões de descarga medida (1210) e desejada (1205). O valor da diferença (1215) é utilizado para determinar o ciclo ativo (1220). Em uma modalidade alternativa, a pressão de gás de descarga (1615) é utilizada para ajustar ciclo ativo (1605) determinado com base nos parâmetros do motor. A diferença (1620) entre as contra-pressões de descarga medida (1615) e desejada (1610) é utilizada para determinar um ciclo ativo de controle de pressão de descarga (1625). O ciclo ativo básico (1605) é então ajustado pelo ciclo ativo de controle de pressão de descarga (1625) para fornecer o ciclo ativo (1630) de um turbocompressor.
