Abstract
EN UN PROCESO PARA LLEVAR A CABO FUNCIONES DE INYECCION SECUENCIALES, CUANDO SE HA ALCANZADO UN ANGULO DE INYECCION PREDETERMINADO, SE GENERAN SEÑALES DE AUMENTO DEL ANGULO DEL EJE DE MANIVELA Y ESTOS AUMENTOS SE CUENTAN RESPECTO A UNA SEÑAL DE REFERENCIA. LAS SEÑALES DE AUMENTO SE UTILIZAN PARA DETERMINAR SI SE HA ALCANZADO UN ANGULO DE INYECCION, EXPRESADO COMO UN VALOR DE AUMENTO. INMEDIATAMENTE DESPUES DE HABER AVERIGUADO ESTO, SE LLEVA A CABO LA FUNCION DE INYECCION ASOCIADA A ESTE VALOR DE AUMENTO, ES DECIR, BIEN SE EMPIEZA O SE DETIENE LA INYECCION. PUESTO QUE LOS ANGULOS DE INICIO DE LA INYECCION Y LOS ANGULOS DE PARADA DE LA INYECCION SE PUEDEN DETERMINAR DE MANERA EXACTA SEGUN ESTE PROCESO, LA POSICION ANGULAR DE LAS FUNCIONES DE INYECCION PARA EL PROCESO DE ADMISION SE PUEDE DETERMINAR DE MANERA MAS EXACTA Y ES POSIBLE EVITAR, CON MAYOR SEGURIDAD TANTO LA PRODUCCION DE MEZCLAS EXCESIVAMENTE RICAS COMO EXCESIVAMENTE POBRES, ASI COMO EL INICIO DE LA FUNCION DE INYECCION DURANTE ELCICLO DE ADMISION PRECEDENTE O FUERA DEL LIMITE DE UN CICLO DE ADMISION DADO.
