Abstract

UN MOTOR DE CRUCETA DE DOS TIEMPOS CON BARRIDO DE FLUJO CONTINUO TIENE UN ANILLO RASPADOR DE COQUE EN UN CILINDRO Y UN PISTON (18) DESPLAZABLE LONGITUDINALMENTE EN EL CILINDRO Y PROVISTO DE AROS DE PISTON (19, 19 ) QUE SE DESLIZAN A LO LARGO DE LA SUPERFICIE INTERIOR SUSTANCIALMENTE CILINDRICA DEL CILINDRO AL DESPLAZARSE EL PISTON Y CREAN UNA SEPARACION ESTANQUIZANTE A LA PRESION ENTRE EL VOLUMEN BAJO EL PISTON Y LA CAMARA DE TRABAJO (20), QUE ESTA SITUADA SOBRE EL ARO DE PISTON MAS ALTO Y ESTA DEFINIDA POR EL ARO DE PISTON MAS ALTO (19 ), EL PISTON (18), LA SUPERFICIE INTERIOR DEL CILINDRO Y LA CUBIERTA DEL CILINDRO (8). EL ANILLO RASPADOR DE COQUE (23) SOBRESALE DE LA SUPERFICIE INTERIOR DEL CILINDRO Y SE EXTIENDEN ANULARMENTE A LO LARGO DE LA MISMA EN UNA POSICION AXIAL DE MODO QUE EL ARO DE PISTON MAS ALTO SE POSICIONA CERCA DEL BORDE INFERIOR DEL ARO RASPADOR DE COQUE CUANDO EL PISTON ESTA EN SU POSICION DE CONTRAPUNTO SUPERIOR. EN SU SUPERFICIE INTERIOR CILINDRICA, EL ANILLO RASPADORDE COQUE (23) ESTA PROVISTO DE VARIOS SURCOS DE ESCAPE (24) QUE SE EXTIENDEN OBLICUAMENTE EN RELACION CON EL EJE LONGITUDINAL DEL CILINDRO DESDE LA SUPERFICIE INFERIOR HASTA LA SUPERFICIE SUPERIOR DEL ANILLO RASPADOR DE COQUE. ALTERNATIVAMENTE, LOS SURCOS DE ESCAPE PUEDEN DISPONERSE EN LA SUPERFICIE EXTERIOR CILINDRICA DE LA SECCION DE PISTON MAS ALTA (21) SITUADOS SOBRE EL ARO DE PISTON MAS ALTO.A TWO-STROKE CROSS ENGINE WITH CONTINUOUS FLOW SWEEP HAS A COKE SCRAPER RING ON A CYLINDER AND A PISTON (18) LONGITUDALLY MOVABLE IN THE CYLINDER AND FITTED WITH PISTON RINGS (19, 19) THAT SLIDE THROUGH THE SUBSTANTIALLY CYLINDRICAL INTERIOR SURFACE OF THE CYLINDER AS THE PISTON DISPLACES AND CREATES A SEALING SEPARATION TO THE PRESSURE BETWEEN THE VOLUME UNDER THE PISTON AND THE WORKING CHAMBER (20), WHICH IS LOCATED ON THE HIGHEST PISTON RING AND IS DEFINED BY THE HIGHEST PISTON RING. HIGHEST PISTON (19), THE PISTON (18), THE INNER SURFACE OF THE CYLINDER AND THE CYLINDER COVER (8). THE COKE SCRAPER RING (23) IS PROJECTED FROM THE INNER SURFACE OF THE CYLINDER AND EXTEND ANNULARLY THROUGH IT IN AN AXIAL POSITION SO THAT THE HIGHEST PISTON RING IS POSITIONED NEAR THE BOTTOM EDGE OF THE COKE SCRAPER RING. THE PISTON IS IN ITS UPPER COUNTERPOINT POSITION. ON ITS INNER CYLINDRICAL SURFACE, THE COKE SCRATCH RING (23) IS PROVIDED WITH SEVERAL ESCAPE GROOVES (24) WHICH EXTEND OBLICUALLY IN RELATION TO THE LONGITUDINAL AXLE OF THE CYLINDER FROM THE BOTTOM SURFACE TO THE UPPER SURFACE OF THE RIGHT SURFACE. ALTERNATIVELY, EXHAUST TRACKS MAY BE AVAILABLE ON THE OUTER CYLINDRICAL SURFACE OF THE HIGHEST PISTON SECTION (21) LOCATED ON THE HIGHEST PISTON RING.
