Abstract
"MOTOR DE COMBUSTãO INTERNA, CáMARA DE COMBUSTãO E PISTãO". A presente invenção refere-se a um motor de combustão interna, particularmente um motor de 4 tempos que opera segundo o ciclo Diesel, compreendendo pelo menos uma carcaça de motor (2) dotada de pelo menos um cilindro (3), no interior do qual está posicionado um pistão (4), o pistão compreendendo uma primeira porção de extremidade (40) dotada de pelo menos uma região de rebaixo (5) na forma de uma câmara de combustão, a câmara de combustão (5) apresentando pelo menos uma primeira porção substancialmente central (50) em formato substancialmente cónico ou troncónico compreendendo pelo menos dois segmentos troncónicos adjacentes (51,52) dotados de inclinações distintas entre si. Adicionalmente, a presente invenção refere-se a uma câmara de combustão (5) provida em um pistão (4) e ao pistão (4) dotado da câmara de combustão (5)."INTERNAL COMBUSTION ENGINE, COMBUSTION AND PISTON CHAMBER". The present invention relates to an internal combustion engine, particularly a diesel-cycle 4-stroke engine, comprising at least one engine housing (2) provided with at least one cylinder (3), within which A piston (4) is positioned, the piston comprising a first end portion (40) provided with at least one recess region (5) in the form of a combustion chamber, the combustion chamber (5) having at least one first portion. substantially central portion (50) in substantially conical or frusto-conical shape comprising at least two adjacent frusto-conical segments (51,52) provided with distinct inclinations from one another. Additionally, the present invention relates to a combustion chamber (5) provided on a piston (4) and a piston (4) provided with a combustion chamber (5).
