Abstract

"PROCESSO PARA OPERAçãO DE UM MOTOR DE COMBUSTãO INTERNA". A invenção refere-se a um processo para operação de um motor de combustão interna (1) especialmente de um veículo automotor, sendo que combustível a ser injetado em uma câmara de combustão (4) ou em um tubo de aspiração (7) do motor de combustão interna se encontra em um armazenador de pressão (13) com uma pressão de injeção (p) variável. Para se possibilitar, em determinados estados operacionais do motor de combustão interna (1), por exemplo após uma partida a frio ou durante uma fase de funcionamento a quente, uma operação ótima do motor de combustão interna (1) relativamente a um consumo de combustível tão pequeno quanto possível e uma emissão de gases de descarga tão reduzida quanto possível, se propõe que a pressão de injeção (p) no armazenador de pressão (13) seja ajustada em função da temperatura (T) do motor de combustão interna (1). De preferência, com uma temperatura (T) do motor de combustão interna (1) abaixo da temperatura operacional do motor de combustão interna (1), a pressão de injeção (p) é elevada. Adicionalmente, a baixas temperaturas (T) do motor de combustão interna (1) o momento de injeção é ajustado para momentos posteriores. (Figura 1)
