Abstract
"SISTEMAS PARA PROPORCIONAR RECIRCULAçãO DE GáS DE DESCARGA PARA O CILINDRO DE UM MOTOR DE COMBUSTãO INTERNA, PARA ABRIR PELO MENOS UMA VáLVULA DE UM MOTOR DE COMBUSTãO INTERNA E PARA UTILIZAR ENERGIA DERIVADA DE UM MOTOR DE COMBUSTãO INTERNA, PROCESSO PARA OPERAR UM MOTOR DE COMBUSTãO INTERNA EM UM MODO DE POTêNCIA EFETIVA E EM UM MODO DE FRENAGEM E ATUADOR DE VáLVULA". Um processo e aparelho para executar uma recirculação de gás de descarga em ritmo de tempo variável é revelado para uso durante tanto em potência efetiva quanto em operação de retardamento de um motor de combustão interna. Movimento ou energia é derivado de um componente do motor (120, 50) e armazenado como energia potencial (500). A energia armazenada é seletivamente aplicada a um atuador de válvula (300) com uma válvula iniciadora eletronicamente controlada (400). O atuador de válvula (300) pode ser um pistão escravo (300) do cilindro (40) em resposta a sistemas hidráulicos independentes de recirculação de gás de descarga e de alívio de compressão.
