Abstract

MOTOR DE COMBUSTãO A DIESEL DE DOIS TEMPOS. A invenção refere-se a um motor de combustão de pistões de movimento alternativo, em particular, um motor a diesel de grande capacidade de dois tempos (1) com expulsão de gases longitudinal. O motor de combustão de pistões de movimento alternativo tem pelo menos um cilindro (10) com uma luva de cilindro (12), na qual um pistão (20) é disposto móvel em vaivém. A luva de cilindro (12) tem várias aberturas de ar de expulsão de gases (45). O dito cilindro (10) tem, além do mais, uma camisa de cilindro (26), que encerra pelo menos uma parte inferior da luva de cilindro (12) e tem uma abertura de camisa de cilindro (27). As aberturas de ar de expulsão de gases (45) se comunicam com a parte interna da camisa de cilindro (26), e o dito pistão é móvel em vaivém, entre uma posição de centro morto de topo, em um lado das ditas aberturas de ar de expulsão de gases (45), e uma posição de centro morto inferior, em um lado oposto das ditas aberturas de ar de expulsão de gases (45). Um meio de deflexão (30) para o ar de expulsão de gases (50) é disposto entre as aberturas de ar de expulsão de gases (45) e a abertura de camisa de cilindro (27), que impede um fluxo linear do ar de expulsão de gases (50), da abertura de camisa de cilindro (27) para as aberturas de ar de expulsão de gases (45), no estado operacional do motor de combustão de pistões de movimento alternativo (1).
