Abstract
A combustion chamber for an internal combustion engine of the direct injection type formed by a cylinder head, a cylinder liner and a piston head, the piston head having formed therein a cavity in which air swirl can be produced by a known device. Fuel injection nozzles are disposed substantially in the central part of said cavity for injecting jets of fuel radially against the cavity wall. Said cavity comprises a generally toroidal cavity formed in said piston head and a plurality of corner cavities formed continuously to said toroidal cavity, each of said corner cavities being defined by a generally linear wall tangent to the inner peripheral wall of said toroidal cavity and a generally semi-circular wall interconnecting said linear wall and the inner peripheral wall of said toroidal cavity, said linear wall being formed upstream side of said air swirl.
