Abstract

CUANDO SE MIRA EN PARALELO AL EJE DEL CENTRO DEL CILINDRO (3), EL GAS DE COMBUSTION QUE SE EXPANDE DESDE EL ORIFICIO DE INYECCION (4) SE ADAPTA PARA FORMAR UN PAR DE HUECOS DE VALVULA (10, 11) SITUADOS EN LOS LADOS OPUESTOS DE UN EJE DE INYECCION (12) DE DICHO ORIFICIO DE INYECCION (4). SE FORMAN UN PAR DE HUECOS DE VALVULA (10, 11) DE FORMA CONCAVA EN LA SUPERFICIE SUPERIOR DEL PISTON (8) DE MANERA QUE ESTEN SEPARADAMENTE DISPUESTOS SOBRE LOS LADOS OPUESTOS DEL EJE DE INYECCION (12) DEL ORIFICIO DE INYECCION (4). LOS CENTROS DE LOS RESPECTIVOS TORBELLINOS (14, 15) DE UN PAR DE FLUJOS DE GAS EN FORMA DE TORBELLINOS (6, 7) SE SITUAN DENTRO DEL PAR DE HUECOS DE VALVULA (10, 11).
