Abstract

unidade injetora para a injeção de um primeiro combustível e um segundo combustível em um espaço de combustão. a presente invenção refere-se a uma unidade injetora (9) para injeção de um primeiro combustível (f~ 1~) e um segundo combustível (f~ 2~) em um espaço de combustão. a unidade injetora (9) recebe o primeiro combustível (f~ 1~) de uma segunda fonte de combustível (7) em que este combustível se encontra a alta pressão, e o segundo combustível (f~ 2~) de uma segunda fonte de combustível (15) em que o segundo combustível se encontra a uma pressão menor do que o primeiro combustível um atuador (29) que inicia um processo de injetar pelo menos o segundo combustível (f~ 2~) no espaço de combustão, e um bico injetor (36) adaptado para injetar pelo menos o segundo combustível (f~ 2~) no espaço de combustão. a unidade injetora (9) compreende um dispositivo aumentador de pressão (40) adaptado para aumentar a pressão do segundo combustível (f~ 2~) a um nível mais elevado do que a pressão na segunda fonte de combustível (15) por um meio da pressão do primeiro combustível (f~ 1~) antes que o segundo combustível seja injetado no espaço de combustão por meio do bico injetor (36).
