Abstract

"MOTOR DISEL COM CONVERSOR CATALìTICO". Trata-se de um motor disel com injetores de unidade (6) e um conversor catalítico (61) disposto no sistema de exaustão do motor (60), para reação com combustível em não combustão. Os injetores possuem válvulas de escape (9), que em sua posição fechada bloqueiam pressão nos injetores, e válvulas de controle de agulha (9), que em sua posição fechada mantém as válvulas de agulha dos injetores fechadas e que, quando elas estão abertas, abrem as válvulas de agulha. Os injetores de unidade possuem êmbolos de bomba, que são conduzidos por elementos de came individuais (12) com uma curva de came (13) formada de modo que uma pressão seja mantida nas injeções por todo o período durante um ciclo, que seja permitida a injeção de combustível pelo menos quando uma válvula de exaustão associada na câmara de combustão comece a se abrir tão tarde durante o curso de expansão e a queda da temperatura, que combustível não entre em combustão no cilindro após a injeção mas alcance a não combustão convertida catalítica. Uma unidade de controle (15) controla a válvula de escape e a válvula de controle de agulha (9) em resposta a vários parâmetros de controle, de modo que pelo menos uma primeira quantidade de combustível possa ser injetada durante o curso de compressão do motor para a combustão habitual na câmara de combustão e que pelo menos uma quantidade adicional de combustível possa ser injetada mais tarde para transporte com a exaustão para o conversor catalítico.
