The invention relates to a combustion method for a reciprocating engine which is adapted to operate with a high level of recirculated burnt gases. According to the invention, during the suction stroke of the piston, a gaseous mass is created from a first zone containing essentially recirculated burnt gases and a second zone containing essentially all of a fresh air combustion charge, said zones being kept separate during the compression of the piston. Subsequently, a fuel is introduced into the aforementioned first zone in order to create a fuel-air mixture which comprises recirculated burnt gases and fuel vapour and which is as homogenous as possible at the end of the compression. Finally, the first and second zones are compressed in order to heat separately the fresh air combustion charge and the fuel-air mixture and said combustion charge and fuel-air mixture are mixed close to the top dead centre of the piston in order to maintain a diffusion flame with the mixtures brought into contact therewith. |
