Abstract

PROCESSO PARA PARTIDA DE UM MOTOR DE COMBUSTÃO DE AUTOIGNIÇÃO A BAIXAS TEMPERATURAS. A presente invenção refere-se a um processo para partida de motor de combustão de autoignição a baixa temperatura com as seguintes etapas: a) introdução de uma primeira quantidade de combustível no compartimento combustor durante um ciclo de compressão do motor de compressão por meio de uma pré-injeção e formação de uma mistura parcialmente homogênea no interior do compartimento combustor; b) introdução de uma quantidade de combustível no compartimento combustor através de uma injeção principal e combustão da mistura de combustível-ar através de autoignição. De acordo com a invenção, início da pré-injeção será escolhido de tal maneira que a pré-mistura parcialmente homogênea pode ser inflamada após um retardo de ignição geralmente curto e é selecionado o início da injeção principal de tal maneira que a quantidade de combustível principal é introduzida dentro do compartimento combustor durante uma fase de combustão ou imediatamente em seguida a uma fase de combustão da prémistura inflamada.
