Abstract

1/1 resumo “método e sistema para controlar um motor turbocarregado durante uma passagem para velocidade mais elevada” a presente invenção refere-se a um método para a propulsão de um veículo (100), por meio do qual o dito veículo (100) compreende um motor de combustão (101) e uma caixa de engrenagens (103), que pode ser ajustada a um número de relações de engrenagem, para a transferência de uma força entre o dito motor de combustão (101) e pelo menos uma roda motriz (113, 114), por meio do que dito motor de combustão (101) compreende pelo menos uma câmara de combustão com pelo menos uma entrada para o suprimento de gás de combustão e pelo menos uma saída para a evacuação de um fluxo de gás de exaustão, que resultou da combustão na dita câmara de combustão, compreendendo ainda uma unidade turbocarregadora (203) para a pressurização do dito gás de combustão. o método compreende, durante a mudança da engrenagem de uma primeira mais elevada relação de engrenagem para uma segunda mais baixa relação de engrenagem, em que a velocidade de rotação do motor de combustão (101) é reduzida de uma primeira velocidade de rotação para uma segunda velocidade de rotação, o seguinte: ­aumentar a pressão (pin) em dita saída (202), pelo menos através do uso da dita unidade turbocarregadora, para constrição do dito fluxo de gás de exaustão, ­reduzir a pressão (pin) em dito gás de combustão, através da abertura de uma primeira válvula (221), e – controlar, quando a velocidade de rotação (n) do dito motor de combustão (101) tiver pelo menos parcialmente caído em direção a dita segunda velocidade de rotação (n2), a dita unidade turbocarregadora (203), de modo que a dita pressão do gás de combustão (pin) seja aumentada. a invenção refere-se também a um sistema e um veículo.
