Abstract

The synthetic combustion method, intended to achieve a reduced fuel consumption and an enhanced flexibility of compression ignition motors both with regards to the revolutions and load range and the sizing range, provides for the complete volume organization of the fluid circulation within the combustion chamber, by the temporary separation of the space of the vortex chamber, of the compartments of the combustion chamber located above the piston, only during the end of the compression period, during the rest of the cycle, the combustion chamber representing a unit, the whole combustion process being a synthesis between the methods of unitary chamber combustion and partitioned chamber combustion, the increase of turbulence being obtained as a result of the vector summing the three vortices at least, tridimensional circulation vortices, and the enhancement of the threshold (squish) effect generated by the piston which increases the decanting effect of the fluid. The combustion chamber has two housings which are separated by a spatial profile which enters the separation channel, profile defined by three direction surfaces at least which generate tridimensional circulation vortices and acts as a braking moving threshold for the vortex housing, by concentrating the rich mixture which burns within the decanting channel area, the fluid circulation within the vortex housing being thus determined, to meet the fuel jet at equicurrent and to displace a portion of the fuel on the incandescent head of a spark-plug.
