Abstract

"CONTROLE ELETRôNICO DE PRESSãO DE COMBUSTíVEL E PROCESSO PARA CONTROLAR A PRESSãO DE COMBUSTíVEL NO ACUMULADOR DE ALTA PRESSãO DE UM SISTEMA DE INJEçãO DE COMBUSTíVEL DE LINHA COMUM". Um sistema e um processo para o controle de pressão de combustível em um sistema de injeção de combustível de linha comum (14) o qual controla eletronicamente uma bomba de alta pressão de descarga variável (16) baseado em entradas de dados da velocidade do motor, do torque e da pressão de linha comum real, assim com da voltagem presente do sistema, por conseqüência proporcionando um controle simples porém estável da pressão de combustível no acumulador (20) do sistema de linha comum (14) e tornando o sistema relativamente insensível a flutuações no suprimento de voltagem da fonte de energia a qual controla a bomba de alta pressão (16).
