Abstract
Patente de Invenção: "INJETOR DE COMBUSTìVEL COM CONTROLE DIRETO DE VáLVULA DE AGULHA". Um injetor de combustível hidraulicamente atuado intensificado (10) possui uma válvula de controle de pressão de combustível independentemente operável (12) disposta no lado de fluido de atuação hidráulico para fornecer uma janela de oportunidade de injeção onde a pressão de combustível é mantida em alta pressão e uma válvula de controle de ajuste independentemente operável (14) disposta no lado de combustível de alta pressão para controlar precisamente os eventos de ajuste de injeção de controle e duração que ocorrem durante um evento de injeção única dentro da janela de oportunidade. Para impedir movimento inverso do êmbolo intensificador (18) durante uma interrupção de injeção enquanto mantém a pressão de injeção completa, a válvula de controle de pressão de injeção (12) permanece aberta enquanto a válvula de controle de ajuste (14) porta combustível sob pressão para uma superfície de trás da válvula de agulha (22) para fechar a válvula de agulha (20). A pressão intensificada completa é fornecida por êmbolo intensificador (18) por todo um evento de injeção único que pode incluir injeção piloto, injeção principal, injeção de formato de taxa, e interrupções e injeção.
