Abstract
resumo patente de invenção: "sistema de pré-câmara para um motor de combustão". a presente invenção refere-se a um sistema de pré-câmara (1) para um motor de combustão com: - uma pré-câmara (2), com uma parede (3), - uma vela de ignição (4) com ,pelo menos, um eletródio (13), - um conjunto alimentador de gás (5), especialmente uma válvula de gás, - um canal de gás (7) que une o conjunto alimentador de gás (5) com a pré-câmara (2) através de um emboque (6), - um canal ascendente (8) para unir a pré-câmara (2) com um compartimento combustor do motor de combustão,- um conjunto condutor (9) para influenciar o fluxo do gás, na pré-câmara (2), sendo que o conjunto condutor (9) está de tal modo disposto vizinho à abertura de emboque (6) de tal maneira que, durante o serviço, pelo conjunto condutor (9) se verifica uma redução do gás quente que alcança a corrente do volume que atinge o eletródio (13) da vela de ignição 4, gás este que, sobre o canal ascendente (8), flui para o interior da pré-câmara (2).
