Abstract

Patente de Invenção: "DISPOSIçãO PARA MOTOR DECOMBUSTãO". A invenção refere-se a um sistema para um motorde combustão interna (1) compreendendo pelo menos dois cilindros(2a-2f), uma entrada (3) para a provisão de ar, uma saída (9,10)para a emissão de gases de escape, um cano adicional (17) para arecirculação de gases de escape de pelo menos um cilindro (2a)no motor (1) para a dita entrada (3) para a redução de emissõesdanosas procedentes do motor (1), e pelo menos uma unidade derecuperação de energia (12) compreendendo um dispositivo (12)para recuperar energia dos gases de escape e também umdispositivo (14) para comprimir ar para a dita entrada (3). Ainvenção é caracterizada pelo fato de que a dita entrada (3) éprojetada com um volume, calculado a partir da conexão (25, 26)do dito cano (17) para a entrada (3) e até o orifício de entrada dosrespectivos cilindros (2a-2f), o qual é dimensionado de modo talque os gases de escape que são recirculados do dito cilindro (2a)são divididos principalmente de modo igual entre os respectivoscilindros (2a-2f) do motor (1). A invenção proporciona um sistemaaperfeiçoado, particularmente para um motor a diesel com umsistema EGR, pelo que se obtém uma distribuição uniforme dosgases de EGR recirculados para o respectivo cilindro (2a-2f).
