Abstract

motor, e veículo e embarcação que compreendem o mesmo. a presente refere-se a um motor que inclui um sistema de escape que tem uma passagem de escape para guiar o gás de escape descarregado a partir de uma câmara de combustão e um sistema de fornecimento de ar para fornecer ar. a passagem de escape é fornecida com uma parte convergente, uma parte divergente e um aparte de bifurcação. a parte de bifurcação divide uma onde de choque, que está se propagando através da passagem de escape em direção à lateral à jusante, a partir da passagem de escape a montante da parte divergente, e permite que a onda de choque se propague novamente através da passagem de escape. o sistema de fornecimento de ar inclui uma primeira passagem que é fornecida com uma primeira válvula de admissão de palheta através da qual um fluxo de ar, percorrendo a partir de uma extremidade a montante em direção a uma extremidade à jusante, passa e tem sua extremidade à jusante conectada à passagem de escape localizada a montante da parte divergente, e um segundo caminho que tem sua extremidade a montante conectada à primeira passagem localizada à jusante da primeira válvula de admissão de palheta. o sistema de escape é disposti para permitir que o gás de escape passe através da parte convergente e colida, entre a parte de bifurcação e a parte divergente, com uma onda de choque que se propagou através fa parte de bifurcação.
