Abstract

ESTRATéGIA PARA ABASTECIMENTO DE MOTOR A DIESEL PELO USO SELETIVO DE MAPAS DE ABASTECIMENTO PARA PROVER MODOS DE COMBUSTãO DE HCCI, HCCI+CD E CD A presente invenção refere-se a um motor de injeção por compressão (20) que tem um sistema de controle (26) para processar dados, uma ou mais câmaras de combustão (22), e injetores de combustível (24) para injetar combustível para dentro das câmaras (22). O sistema de controle (26) controla o abastecimento usando o resultado do processamento de certos dados, tais como velocidade do motor e carga do motor, para selecionar um dos três modos de abastecimento (HCCI, HCCI+CD, CD) para operar o motor (20). Quando o resultado do processamento seleciona o modo de HCCI, o motor (20) é abastecido para causar a combustão de ignição por compressão com carga homogênea (HCCI) em todas as câmaras de combustão (22). Quando o resultado do processamento seleciona o modo de HCCI+CD, o motor (20) é abastecido para causar a combustão de HCCI em algumas câmaras (22) e a combustão de CD (diesel convencional) nas câmaras restantes (22). Quando o resultado do processamento seleciona o modo de CD, o motor (22) é abastecido para causar a combustão de CD em todas as câmaras (22).
