Abstract

UN MOTOR DE COMBUSTION INTERNA QUE TIENE UN PRIMER Y UN SEGUNDO CILINDROS (12, 14), EN DONDE EL PRIMER CILINDRO (12) TIENE UN VOLUMEN DE BARRRIDO MAYOR QUE EL SEGUNDO CILINDRO (14) Y EL SEGUNDO CILINDRO ESTA FORMADO EN UNA CORONA DEL PRIMER CILINDRO. HAY UN PRIMER Y UN SEGUNDO PISTONES (16, 18) QUE VAN Y VIENEN DENTRO DEL PRIMER Y SEGUNDO CILINDROS RESPECTIVAMENTE (12, 14) Y EL SEGUNDO PISTON (18) ESTA FORMADO COMO UN SALIENTE SOBRE LA CORONA DEL PRIMER PISTON (16). EL PRIMER CILINDRO TIENE UN ORIFICIO DE ENTRADA DE AIRE (25) Y UN ORIFICIO DE ESCAPE (27) MIENTRAS QUE UNA PRIMERA FUENTE DE COMBUSTIBLE (34) PROPORCIONA COMBUSTIBLE AL SEGUNDO CILINDRO ((14). EL SEGUNDO PISTON TIENE UNA CORONA (35) SEPARADA Y CONECTADA A LA CORONA (36) DEL PRIMER PISTON Y TIENE UN REBORDE (37) RELATIVAMENTE DELGADO EN LA DIRECCION AXIAL EN COMPARACION A LA SEPARACION DE LA CORONA DEL PRIMER PISTON DE LA CORONA DEL SEGUNDO PISTON. ESTO DEFINE UN ESPACIO DE COMBUSTION (20) ENTRE LAS CORONAS DE LOS PISTONES Y UNAPARED LATERAL (14A) DEL SEGUNDO CILINDRO (14) CUANDO LOS PISTONES SE ENCUENTRAN SUSTANCIALMENTE EN LA POSICION DE PUNTO MUERTO INTERIOR. EL ESPACIO DE COMBUSTION (20) ENTRA EN COMUNICACION CON LOS DOS CILINDROS (12,14) DURANTE PARTE DE LA CARRERA DE EXPANSION. EN COMUNICACION CON EL ESPACIO DE COMBUSTION HAY UNA BUJIA (52). TAMBIEN HAY UN ELEMENTOS INHIBIDORES PARA INHIBIR LA ENTRADA ANTES QUE LOS PISTONES (16, 18) QUE LLEGAN A O ADYACENTES A LA POSICION DE PUNTO MUERTO INTERIOR. ESTOS PUEDEN TENER FORMA DE ESPACIO (128) ENTRE LA SEGUNDA CORONA DEL SEGUNDO PISTON (35) Y LA SEGUNDA PARED LATERAL DEL CILINDRO (14A) CON UNA RANURA PERIFERICA (399 EN LA PARED DEL SEGUNDO CILINDRO EN EL EXTREMO SUPERIOR PARA PERMITIR LA MEZCLA DE AIRE Y COMBUSTIBLE EN EL SEGUNDO CILINDRO (14) POR ENCIMA DE LA CORONA (35) PARA QUE PARA QUE DESVIE A LA CORONA DEL PISTON CUANDO ESTE SE ENCUENTRA EN LA POSICION DE PUNTO MUERTO INTERIOR Y ENTRA EN EL ESPACIO DE COMBUSTION (20). SE ELIGE EL COEFICIENTE DE COMPRESION GEOMETRICA DEL MOTOR, ENCONTRANDOSE EL COEFICIENTE DE LOS VOLUMENES DENTRO DE LOS CILINDRO DISPONIBLE PARA SER OCUPADO POR EL GAS EN LAS POSICIONES DE PUNTO MUERTO INTERIOR Y EXTERIOR DEL PISTON, PARA ASEGURARSE QUE LA PRESION Y LA TEMPERATURA ALCANZADAS EN DICHO ESPACIO DE COMBUSTION CERCA DEL FINAL DE LA CARRERA DE COMPRESION SON INSUFICIENTES COMO PARA PROVOCAR EL ENCENDIDO POR COMPRESION ESPONTANEA DEL COMBUSTIBLE UTILIZADO. EL PROCESO DE ENCENDIDO SE EMPIEZA CON UNA CHISPA Y SE DEJA QUE CONTINUE MEDIANTE UN ENCENDIDO POR COMPRESION. UNA VEZ COMENZADO EL ENCENDIDO POR CHISPA, LA LLAMA AUMENTA LA TEMPERATURA Y LA PRESION DEL GAS QUE SE ENCUENTRA EN EL ESPACIO DE COMBUSTION LO SUFICIENTE COMO PARA PROVOCAR EL ENCENDIDO POR COMPRESION DEL RESTO DEL COMBUSTIBLE VAPORIZADO A MEDIDA QUE ENTRA EN EL ESPACIO DE COMBUSTION DEBIDO A LA ACCION DEL PISTON MAS PEQUEÑO Y SE MEZCLE CON MAS AIRE.
