Abstract

UN MOTOR DE COMBUSTION INTERNA, PREFERENTEMENTE UN MOTOR DE DOS TIEMPOS, QUE TIENE UNA CABEZA DE CILINDRO (12) EN UN EXTREMO DEL CILINDRO (5), UN PISTON (6) MONTADO PARA SU ALTERNACION EN EL CILINDRO (5), UNA CAVIDAD (13) EN LA CABEZA DEL CILINDRO (12) Y UNA BOQUILLA DE INYECCION DE COMBUSTIBLE SITUADA EN LA CAVIDAD (13) EN LA CABEZA DEL CILINDRO (12) PARA SUMINISTRAR COMBUSTIBLE A LA CAVIDAD (13) EN DIRECCION HACIA EL PISTON (6). TENIENDO EL PISTON (6) UN CUENCO (31) EN SU PARTE SUPERIOR SITUADO PARA CORTAR EL PASO DE SUMINISTRO DEL COMBUSTIBLE DESDE LA BOQUILLA DE INYECCION. UNA PESTAÑA (32) QUE SE EXTIENDE ALREDEDOR DE LA PERIFERIA DEL CUENCO (31) Y QUE ESTA VERTICAL EN LA SUPERFICIE SUPERIOR DEL PISTON (6). EL CUENCO (31) Y LA PESTAÑA (32) EFECTUAN UNA CONTENCION DEL COMBUSTIBLE PARTICULARMENTE DURANTE NIVELES DE ABASTECIMIENTO DE COMBUSTIBLE ALTOS PARA CONTROLAR EL PROCESO DE COMBUSTION.
