Abstract

Patente de Invenção: <B>''SISTEMA DE CONDICIONAMENTO DE CARGA PARA PERMITIR O ARRANQUE A FRIO E O FUNCIONAMENTO DE MOTORES DO TIPO PISTãO OPERADOS POR COMBUSTìVEL DIESEL, COM IGNIçãO A CENTELHAS''<D>. <B> ANTECEDENTES DA INVENçãO<D>. Motor de combustão interna, operado por combustível diesel, do tipo pistão, com ignição a centelhas, é dotado de um sistema de condicionamento de carga, que inclui um pré-aquecedor de combustível para vaporizar combustível líquido a fim de permitir a partida do motor e pelo menos um aquecedor secundário para acrescentar calor adicional à carga fornecida ao motor. O vaporizador de combustível recebe combustível líquido do circuito de combustível de partida do motor e usa um dispositivo aquecedor, energizado eletrica ou quimicamente, ou um aquecedor de combustão direta. O aquecedor secundário pode estar associado com o conduto de entrada de carga do motor ou com a câmara de combustão do motor. O dispositivo aquecedor secundário pode ser ativado eletrica ou quimicamente, ou pode constituir um regenerador de calor que retém calor de um ciclo de combustão anterior do motor. A incrustação na vela de ignição é evitada pela utilização de câmaras secundárias adjacente à câmara de combustão do motor que dirigem jatos de expansão de gases de alta velocidade para os eletrodos das velas de ignição a cada ciclo de combustão, durante o curso de alimentação de energia do pistão.primeiro dispositivo de aquecimento
