ABSTRACT:
A compression ignition, direct injection internal combustion engine which includes at least each one cylinder, with an associated piston and injection nozzle, the piston having a combustion chamber in its head in the form of a body of rotation. The combustion chamber includes below the crown of the piston a constriction which divides the chamber in an upper part and a lower part. The connecting passage formed by the constriction between the upper part and the lower part of the chamber includes a number of additionally connecting canals in the region of the circumference of the chamber, which are groovelike and open to the chamber.
Based on the specific forms and arrangements of the connecting canals, a marked micro turbulence of the cylinder charge, a better mixture formation and an improved combustion process, with lower amounts of unburnt hydrocarbons and soot in the exhaust, is achieved.
