Abstract

A combustion chamber in an opposed-piston, internal-combustion engine is disclosed in which the pistons tops are designed so that when they approach each other, they induce a tumble flow in one or two hemispherical spaces defined in the piston tops. The combustion chamber further includes injectors side mounted in the cylinder wall. In one embodiment, the tumble flows in the two hemispheres are in the same direction and in another embodiment, in opposite directions. In yet another embodiment, there is only one injector and one hemisphere in which a tumble flow is induced.
