Abstract

um motor de combustão interna inclui uma passagem de admissão do motor de combustão interna, uma passagem de descarga do motor de combustão interna, uma passagem egr conectando a passagem de admissão e a passagem de descarga. o motor de combustão interna inclui ainda uma válvula de estrangulamento fornecida à jusante de uma parte conectada à passagem egr na passagem de admissão e configurada para controlar uma quantidade de ar de admissão fluindo para dentro do motor de combustão interna, e uma válvula de estrangulamento de admissão fornecida à jusante da parte conectada à passagem egr na passagem de admissão. um dispositivo de controle controla o motor de combustão interna, em cujo dispositivo um grau de abertura da válvula de estrangulamento de admissão é determinado com base em uma quantidade de ar de admissão.
