Abstract

UN SISTEMA ELECTRONICO PARA IDENTIFICAR LOS TIEMPOS DE UN MOTOR DE COMBUSTION INTERNA DE CUATRO TIEMPOS, QUE TIENE UN EJE CIGUEÑAL DE SALIDA UNIDO A UN SENSOR DE POSICION ANGULAR QUE GENERA UNA SEÑAL CON UN INTERVALO DE 360 GRADOS DEL EJE CIGUEÑAL. LA SEÑAL TIENE AL MENOS UNA REFERENCIA 0 QUE CORRESPONDE A UNA REFERENCIA 0 DEL EJE CIGUEÑAL. EL SISTEMA PUEDE DETECTAR (100) LA REFERENCIA 0 Y ASIGNAR ARBITRARIAMENTE (11) LOS TIEMPOS DEL MOTOR (2) CON RESPECTO A LA REFERENCIA 0, DETERMINANDO AL MENOS UNA RELACION ANGULAR ESPECIFICADA ENTRE LA REFERENCIA 0 Y LA POSICION ANGULAR EN LA CUAL EL CENTRO MUERTO SUPERIOR DE UN PRIMER CILINDRO ES ALCANZADA. EL SISTEMA PUEDE MONITORIZAR (131,133) LAS TORSIONES GENERADAS POR LOS DOS CILINDROS DEL MOTOR PARA DETECTAR UNA RELACION DE TIEMPO ENTRE ESTAS TORSIONES, Y PARA RECONOCER UN DESPLAZAMIENTO DE TIEMPO DE 360 GRADOS EN LOS TIEMPOS ARBITRARIAMENTE ASIGNADOS. EL SISTEMA TAMBIEN PUEDE REPROGRAMAR (136) LOS TIEMPOS ASIGNADOS ARBITRARIAMENTE.AN ELECTRONIC SYSTEM TO IDENTIFY THE TIMES OF A FOUR-TIME INTERNAL COMBUSTION ENGINE, WHICH HAS AN OUTPUT CRANKSHAFT SHAFT ATTACHED TO AN ANGULAR POSITION SENSOR THAT GENERATES A SIGNAL WITH A 360 DEGREE INTERVAL OF THE CRANKSHAFT SHAFT. THE SIGNAL HAS AT LEAST ONE REFERENCE 0 THAT CORRESPONDS TO A REFERENCE 0 OF THE CRANKSHAFT. THE SYSTEM CAN DETECT (100) THE REFERENCE 0 AND ASSIGN ARBITRARILY (11) THE MOTOR TIMES (2) WITH RESPECT TO THE REFERENCE 0, DETERMINING AT LEAST A SPECIFIC ANGLE RELATION BETWEEN THE REFERENCE 0 AND THE ANGLE POSITION IN WHICH THE CENTER DEAD SUPERIOR OF A FIRST CYLINDER IS REACHED. THE SYSTEM CAN MONITOR (131,133) THE TORQUES GENERATED BY THE TWO ENGINE CYLINDERS TO DETECT A TIME RELATION BETWEEN THESE TORQUES, AND TO RECOGNIZE A TIME DISPLACEMENT OF 360 DEGREES IN THE ARBITRARELY ASSIGNED TIMES. THE SYSTEM CAN ALSO REPROGRAM (136) THE TIMES ARBITRARILY ASSIGNED.
