Abstract

EL SISTEMA COMPRENDE DETECTORES (3) QUE DETECTAN PARAMETROS DEL MOTOR, UN DISPOSITIVO DE INYECCION ELECTRONICO (4)UN BLOQUE QUE CONTROLA EL DISPOSITIVO DE INYECCION EN CONDICIONES DE SUMINISTRO DE MEZCLA AIRE-COMBUSTIBLE NORMALES; MEDIOS (23) QUE COMPARAN PARA CADA FASE DE MOTOR EL VALOR (F) DE LA POSICION DE LA VALVULA DE MARIPOSA DEL COLECTOR DE INDUCCION DE AIRE CON UN PRIMER VALOR DE UMBRAL (MF1); MEDIOS (24) QUE PARA CADA FASE DE MOTOR, COMPARAR EL VALOR (RPM) DE LA VELOCIDAD DE MOTOR CON UN SEGUNDO VALOR DE UMBRAL (MRPM1); Y MEDIOS (25) ACTIVADOS SI EL VALOR DE POSICION DE MARIPOSA ES INFERIOR AL PRIMER VALOR DE UMBRAL Y EL VALOR DE LA VELOCIDAD DE MOTOR ES MAYOR QUE EL SEGUNDO VALOR DE UMBRAL PARA CONTROLAR, PARA CADA CILINDRO DEL MOTOR Y DE ACUERDO A UNA TABLA (28) LA VELOCIDAD DE ENTRADA DE MEZCLA DE AIRE-COMBUSTIBLE DE MANERA A CAMBIAR DE CONDICIONES DE SUMINISTRO DE COMBUSTIBLE NORMALES A UNA CONDICION DE PARADA DE MEZCLA CON UNA LEY DE PREDETERMINADA DE VARIACION DE PAR MOTOR.THE SYSTEM INCLUDES DETECTORS (3) THAT DETECT ENGINE PARAMETERS, AN ELECTRONIC INJECTION DEVICE (4) A BLOCK THAT CONTROLS THE INJECTION DEVICE IN NORMAL AIR-FUEL MIXING SUPPLY CONDITIONS; MEANS (23) THAT COMPARE FOR EACH ENGINE PHASE THE VALUE (F) OF THE POSITION OF THE BUTTERFLY VALVE OF THE AIR INDUCTION MANIFOLD WITH A FIRST THRESHOLD VALUE (MF1); MEANS (24) THAT FOR EACH MOTOR PHASE, COMPARE THE VALUE (RPM) OF THE MOTOR SPEED WITH A SECOND THRESHOLD VALUE (MRPM1); AND MEANS (25) ACTIVATED IF THE BUTTERFLY POSITION VALUE IS LESS THAN THE FIRST THRESHOLD VALUE AND THE MOTOR SPEED VALUE IS GREATER THAN THE SECOND THRESHOLD VALUE TO CONTROL, FOR EACH ENGINE CYLINDER AND ACCORDING TO A TABLE (28) THE AIR-FUEL MIXING INLET SPEED SO AS TO CHANGE FROM NORMAL FUEL SUPPLY CONDITIONS TO A MIXING STOP CONDITION WITH A DEFAULT MOTOR TORQUE VARIATION ACT.
