Abstract

Perfections introduced in an internal combustión engine, of stratified charge, including: at least one cylinder closed by a cylinder head, in which at least one combustión chamber is provided; a piston suitable for sliding in the or each cylinder, having a head provided with a protuberance suitable to cooperate with a housing of the cylinder head, this housing having an open face according to the direction of displacement of the piston, in order to receive said protrusion and determining, in the combustión chamber, an auxiliary chamber; means for introducing a fuel-rich mixture into this auxiliary chamber; and ignition means of the fuel rich mixture of the auxiliary chamber.
