Abstract

UNIDADE DE ALIMENTAÇÃO E MEMBRO DE INGRESSO DA MESMA. A presente matéria refere-se a uma unidade de alimentação (200) que compreende um bloco cilíndrico (220) e um cabeçote cilíndrico (225). O cabeçote cilíndrico (225) é montado ao bloco cilíndrico (220). O bloco cilíndrico (220) e o cabeçote cilíndrico (225) definem uma câmara de combustão (230) para a combustão de uma mistura de ar e combustível. Um membro de ingresso (300) conecta um regulador de fluxo (270) ao cabeçote cilíndrico (220). O membro de ingresso (300) compreende uma porção a montante (316) e uma porção a jusante (317). A porção a montante (316) do membro de ingresso compreende uma porção de melhora de fluxo (325) que se estende radialmente para dentro da mesma. A presente matéria aprimora o fluxo de tamboreamento sem afetar a construção existente do cabeçote cilíndrico. O fluxo de tamboreamento aprimora a mistura de mistura de ar e combustível, aprimorando-se, assim, a combustão, e reduz emissões.FOOD UNIT AND ENTRY MEMBER THEREOF. The present matter relates to a feeding unit (200) comprising a cylindrical block (220) and a cylindrical head (225). The cylindrical head (225) is mounted to the cylindrical block (220). The cylindrical block (220) and the cylindrical head (225) define a combustion chamber (230) for combusting a mixture of air and fuel. An inlet member (300) connects a flow regulator (270) to the cylindrical head (220). The ingress member (300) comprises an upstream portion (316) and a downstream portion (317). The upstream portion (316) of the ingress member comprises a flow enhancing portion (325) extending radially inwardly therefrom. The present material improves tumbling flow without affecting the existing cylinder head construction. The tumbling flow improves mixing of the air and fuel mixture, thereby improving combustion and reducing emissions.
