Abstract
"CAVIDADE DE COMBUSTãO NO FUNDO DE UM êMBOLO PARA UM MOTOR DIESEL". A presente invenção refere-se a uma cavidade de combustão (4) no fundo (1) de um êmbolo (2) provido de um canal de resfriamento (9), por exemplo, em forma de um suporte anular (7) resfriado, para um motor diesel, que na área da borda radialmente externa apresenta um corte traseiro (8), formado de tal modo que, para um efeito de resfriamento do canal de resfriamento (9) sobre a cavidade de combustão (4), o limite radialmente externo da cavidade de combustão (4) está disposto suficientemente próximo do canal de resfriamento (9).
